Musk’s product design once again swept our field of vision, this time it was a humanoid robot.

Tesla Optimus Prime Product Design Path

On September 30th, Optimus Prime, which aims to "reshape the future of the labor force", was released, adding more variables to the product design of humanoid robots.

On August 11th, before Tesla, Xiaomi released his own humanoid robot CyberOne, code-named "Tieda". A well-known domestic artificial intelligence solution provider, Ubisoft, also released a new generation of Walker X in October last year.

The isometric drawings of Optimus Prime and other large-scale product designs.

However, if the DEMO released this time is shown to the Japanese fifty years ago, I’m afraid the product designers will be disappointed. As early as 1972, Waseda University in Japan had made the first full-size humanoid robot WABOT, which could communicate in Japanese, navigate indoors and grab objects.

Wabot is highly similar to the DEMO of Optimus Prime.

Fifty years later, humanoid robots seem to be stuck in the castle in the air of cutting-edge technology, and it is difficult to get out of the laboratory and land. Aside from Tesla’s brand aura, where does the future design of humanoid robots lead?

Chronicle of Honda ASIMO product design

From psychology to art, from product application to steering gear cost, humanoid robot may be the most challenging product design in human history.

Challenge uncanny valley.

In the classic book Crossing the Gap, Geoffrey Moore thinks: "The most dangerous and crucial point in the process of high-tech products coming out is the transition from the early market dominated by a few visionaries to the mainstream market occupied by a large number of customers dominated by pragmatists."

Tesla CyberTruck’s sense of the future is inseparable from industrial design.

Compared with Tesla’s previous CyberTruck and Model electric cars, humanoid robots rely more on industrial design. Only in this way can we achieve a thrilling leap from laboratory prototype to commercialization.

The theory of horror valley belongs to the industrial design of humanoid robots. If humanoid robots try to approach real people from various characteristics, users’ expectations for design will be unattainable.

"uncanny valley" Psychological Theory in Robot Design

Once designers pay too much attention to appearance and emotional expression, such as trying to recreate human muscles and skin, they will easily fall into uncanny valley, and become a failed commodity like the "corpses" of countless laboratory DEMO lying at the bottom of the valley.

The list of "scary robots" on IEEE

Zhang Haochong, director of Naiyang Creative Design, said: No matter from the design trend or the current product technology, the more effective design ideas are not to challenge the "uncanny valley", to resist the impulse of design, and to design robots as "digital products" and "home appliances" to avoid the corresponding seats for real people.

This means that on the left side of uncanny valley, there is still a vast design space to prove the consumption value.

How many obstacles are there to overcome in designing the dream humanoid robot commodity?

Overcoming Moravik Paradox

In fact, the design of humanoid robots has never been seen by the AI industry.

In 2012, teacher Kai-fu Lee once commented that the idea that humanoid robots will enter thousands of households immediately is simply nonsense.

Peter teale, the founder of Paypal, came to the same conclusion: "It’s just a simple action to let the robot take out the dirty clothes from the basket and put them into the washing machine". In the opinion of the engineers he communicated with, "it can’t be seen in his lifetime."

The criticism of AI predecessors is not groundless. Its foundation is actually one: Moravik paradox.

Humanoid robots are smart, but their movement ability can never keep up with the algorithm.-Because the existing motors and sensors are not accurate enough, the limbs are extremely underdeveloped. It can copy the story of AlphaGo countless times, easily defeating humans in data calculation and quiz, but it can’t twist a door handle and pick up a water cup accurately-not as good as a three-year-old child.

All children’s sports skills: picking up pencils, running and jumping, and tightening bottle caps-all are the most difficult problems for humanoid robots so far. A cold joke in the AI industry is that manual jobs such as gardeners, receptionists and chefs don’t have to worry about being replaced within 30 years.

The limitation of Moravik’s paradox is what all robot designers need to face up to.

The daunting design cost.

The industrial design of humanoid robot needs abundant funds to irrigate it.

The joints of Tesla Optimus Prime contain a large number of motors.

To create a perfect robot design, ABS plastic shell and color matching are only small heads among small heads, and a large number of joints and servo steering gears are needed to support the design.

Exploded view of millet CyberOne hip motor structure

Relevant practitioners have revealed that the cost of servo steering gear system accounts for 40% to 50% of sports robots. The multi-stage steering gear needed to realize human action design and the high price of accessories force humanoid robots to bid farewell to high quality and low price at the consumer end.

The common servo steering gear on Taobao is expensive.

Tesla shouted out a customer unit price of $20,000 at the press conference, but this is still not an acceptable price for the consumer market.Even in the field of children, considering the lower customer unit price of toy robots, the high cost of motors will not change because of their size, which greatly reduces the cost space.

Small steering gear for children’s toys is also expensive.

For Tesla and any robot, the whole body needs countless steering gears to drive, and the cost fluctuation of any motor is a factor that cannot be ignored when designing products.

Home furnishing field

If you want to design humanoid robots for the home field, the first thing to consider is the material and color matching.

White material is a common color for household appliances in industrial design. It has also become the home color matching standard for humanoid robots.

However, the curse of Moravic’s paradox is the strongest in the field of home.

Although the humanoid home robot has always been a design that attracts people’s attention, it has always been far from the designer’s expectations: since its inception, humanoid robots have been subjected to various "less human-like" home robots.

From 2021 to 2022, Aqara Green Rice and Eurobo completed financing with a total amount of 1 billion yuan respectively. It has become the two largest financing for smart homes in recent years. Humanoid robot and smart home are both capital-intensive industries, but the former is a research and development need, and the profit is far away; The installed capacity of the latter products is well documented.

Aqara’s various professional home robot matrices

In Japan, where ASIMO home robot was born, there is a unique SwitchBot company.

Its product design style is to use a small motor to quickly control the common buttons and door handles at home. To achieve the same function, humanoid robot needs the identification, positioning and linkage of dozens of servo motors.

The humanoid robot needs dozens of steering gears to twist the door handle.

A large number of micro-powered robots directly skipped the defense line of Moravik paradox. When humanoid robots are still studying how to form a mechanical arm with a variety of steering gears, press the switch and unlock the door lock with high precision, the IoT robot chose to reduce the dimension.

The best-selling button robot in Hong Kong, Macao and Taiwan and Japan.

This is a moment that has appeared many times in the history of industrial design: in the 19th century, Germans once carved guns with the same high quality as works of art, which is still a model of design collection; The British designed a cheap, simple gun which is suitable for rapid and large-scale industrial manufacturing. When low-cost small steering gear can quickly realize the home scene of dozens of heavy steering gear linkage, the balance of war will inevitably tilt to the other side of the humanoid vase.

The search volume of Google Trend, a home robot, is significantly higher than that of humanoid robots after 2011.

What few people know is that before Tesla and Xiaomi’s robots, the once-popular Honda ASIMO home robot officially retired in March 2022.

On March 31st, 2022, Honda ASIMO robot officially retired.

The performance of humanoid robots on the home stage has ended before it started.

Although this expression is somewhat cruel, it is hard not to think that the design behind Tesla’s "Optimus Prime" and Xiaomi’s CyberOne today is just a replica of the defeated soldiers in the home battlefield.

An educational scene that is beyond one’s power

Outside the smart home stage, humanoid robots could have found another way to capture children’s desks as "educational robots".

The design opportunity began in 2017, when the State Council issued the artificial intelligence education policy.

This policy has greatly stimulated the demand for robot education. In front of major companies, it is a grand blue ocean market. In 2018, Ubisoft hired Takahashi Zhilong, who had designed RoBohon robot, as the chief product officer to take charge of product design.

China and Japanese robot industry designers met on the education track.

Everything about the humanoid educational robot looks beautiful.

Take the "Wukong" released in 2019 as an example. The size of the mini makes it not be regarded as a real person, avoiding the pit of the horror valley effect; As the most acceptable interactive carrier for children, humanoid can play the role of children’s learning companion and promote students’ social skills of communicating with others, understanding emotions and expressing. You can also get through all kinds of educational IP and become a traffic portal.

However, there have been professional teachers’ voices opposing humanoid design.

The reason is the familiar Moravik paradox: the educational subjects of humanoid robots are mainly mathematics, physics and engineering project learning, and the reasonable and efficient educational product modeling is actually not bound by humanoid.

The best-selling robots in Amazon, USA, are usually wheeled or tracked.

A robot product designer before making a child’s heart gave an example of an excavator: assuming that the mechanical arm and the principle of the mechanical arm should be taught in the primary school curriculum, the product form should reflect the semantics of mining. In modern classroom teaching, when introducing the popular science of robots, children’s reaction after getting humanoid robots is bound to exceed expectations: "Can it help me move things?" "Can these two robots race?"

Motionblock modular robot is a typical idea of split design according to projects.

Among them, the ability to walk and exercise is far beyond the ceiling that humanoid robots can meet from the beginning.

Teacher Cheng, who has used Alpha and Wukong robots to write courses, said: "Humanoid robots are very cost-effective and can’t support a few classes." Ye Yonghao, chairman of Yuzhi Kechuang, revealed: "Humanoid robots usually have requirements for venues and teachers, and institutions will not use human figures. Primary and secondary schools rarely introduce it. Even if there is, it is also the display purpose led by the Education Bureau. "

Modular educational robot occupying the market

The consensus reached by the education sector not only that teaching should not be restricted by human design, but also includes the need for emotional expression.

In April 2001, in Los Angeles, a studio named Cozmo Robot was established. Its products will be praised by many robot teachers, designers and even small bosses of Dongguan toy factory, and will occupy a very heavy weight in the design history of robots and educational toys.

Vector is not a humanoid design, but the introduction of LED panel brings emotional design to the extreme.

What makes Cozmo famous is the extremely rich emotional design. "This is what robots should look like. Please stop making humanoid robots like nightmares!" Become a representative of the consumer market.

High praise product reviews under the evaluation of Unbox Therapy

Cozmo’s design idea reduces the market’s dependence on human form and turns to richer expression design to meet the better output of children’s content. Drive the head expression of humanoid robot to develop in a rich and delicate direction.

The subsequent development has nothing to do with human form:After 2020, with the outbreak of online education and the decrease of the cost of superimposed screen components, the design trend is to further enlarge the expression panel and cut off the expensive humanoid joints.The industrial design at this stage is essentially a tablet computer dragging its body and speakers.

Image source: finishing by the author

Zhang Haochong, who has participated in Corbit, mTiny and Codey Rocky, pointed out the reasons:No matter the cost of steering gear, the feasibility of technology or the actual cost, its content can not bear the main responsibility of humanoid robot as education.

From school to family, from desks to dining tables, a large number of modular and kit toys and teaching AIDS have occupied the fields that Takahashi Zhilong and humanoid robots once dreamed of. However, due to the lack of support from professional B-end users, the proportion of humanoid modeling in the educational product line will inevitably decline.

Commercial performances and reception scenes

Tesla "Optimus Prime" pays attention to different physical labor scenes, and the commercial exhibition and reception in Chinese mainland is the undisputed home of humanoid robots.

The annual Spring Festival Gala is a battleground for all kinds of traffic operations for China Internet companies; For humanoid robots, it is a window to show product design.

In 2016, 540 Alpha humanoid robots landed in the Spring Festival Evening of the Year of the Monkey, and completed the product appearance in the song of Sun Nan’s "Rushing to the Peak"; Three years later, six Walker robots landed at the Shenzhen Branch of the Spring Festival Evening again. Subsequently, Ubisoft received a $100 million investment from CDH and CITIC Jinshi, and the overall valuation of the company reached $1 billion.

This is a pre-advertised product show. On the one hand, as a new product, it takes an educational process for design to go to the consumer market, and Spring Festival Evening Harmony is the best market promoter of product design. On the other hand, humanoid robots with excellent appearance and tonality in line with business scenes help to drain variety shows and offline shopping malls and tell a more technological brand story.

However, far from the performance of financing aura:In the field of domestic leasing, the product design with good sales performance is actually a wheeled flat-panel robot dominated by domestic Da Yun robots.

SoftBank Pepper, similar to Da Yun, receives robots.

In contrast, Ubisoft’s best-selling commercial reception robot is not a humanoid, but a Cruzr robot that also provides information consultation with a large tablet computer.

The choice of enterprises is clear-cut: avoiding the humanoid design with higher cost and more instability at this stage, and realizing offline service efficiency through AI voice and content. As for whether the product design is bipedal and conforms to the humanoid ideal of designers and engineers, it is not for enterprises to consider.

In any case, the B-end products support the valuation confidence of the industry. In April 2019, the representative of domestic humanoid robot, You Bixuan, started filing counseling at Shenzhen Securities Regulatory Bureau and started the journey of IPO listing.

At this moment, it is less than 10 months before the full-scale outbreak of the COVID-19 epidemic.

Epidemic prevention medical care, failed answer sheet

When the epidemic spread around the world, the design route of humanoid robots was also subverted.

Faced with such a large-scale epidemic and the emerging demand for massive service robots, designers suddenly found that wheeled robot talents are the solution to deal with the epidemic quickly.

The medical robot of Cizhi Wei ‘an has no obvious humanoid bipedal design.

As a result, there is no doubt that all kinds of unmanned vehicles have played a far more important role than humanoid robots. After 2020, humanoid robots are absent from both epidemic prevention service robots and rehabilitation service robots released in 2022.

European and American designers from the other side of the ocean, without China and Japan’s attachment to the biped scheme, adopted the wheeled design scheme "pragmatically". At this point, the stage of epidemic prevention and medical service has been decoupled from the design of humanoid robot.

The epidemic in COVID-19 seems to have nothing to do with humanoid robots, but it seriously overdraws the design funds-humanoid robots that are difficult to make profits in the short term and break through the technical bottleneck are even more backward in product application.

Entertainment and IP

The ebb tide of humanoid design does not seem to affect the surrounding IP and film and television products.

Why can today’s humanoid design still occupy a place? Essentially, humanoid robots are still enjoying the afterglow of all kinds of capital, media and IP. It has always been the global animation and film industry that has a profound impact on the product design of manufacturing industry, not the other way around.

When Takahashi Chihiro, the designer of the current article, was still studying at Ritsumeikan University in Kyoto, the Gospel Warrior of the New Century was already popular in East Asia, and at this moment, it has been 30 years since the humanoid robot Astro Boy was first serialized.

IP has a great influence on public cognition and product design.

When the design of humanoid robots lacks depth and fails to meet the public’s expectations of various classic IP, no matter how much design efforts, it will become a market failure. When one consumer story after another is finished, the humanoid robot persists except for the IP stage, and the audience on other stages has already gone empty.

The only purpose of design seems to be to stimulate investment.

Brand window telling vision

As the ceiling of humanoid design technology, Boston Power is probably a bumpy demonstration of stimulating investment.

Long ago, Boston Dynamics stated that it was, is and will be a money-burning company for a long time.

Although it has solved the problem of humanoid motion performance well enough, it has changed hands three times in seven years, and it has successively moved to Google, Softbank and Hyundai, which accurately illustrates the embarrassing situation that humanoid design lacks profit: enterprises are more inclined to use it as an imaginative tool to mobilize investment value, and once its revenue fails to meet expectations, it will be cut decisively.

This is similar to the underlying logic of Xiaomi’s project to build cars and robot products. Regardless of the impact of releasing humanoid robot products on business, it is definitely timely in stock price and future vision.

Xiaomi CyberOne Design Conference Site

This means that Xiaomi’s brand imagination has a new short-term anchor object.

Today’s Tesla has also learned how to pull this stock price. Musk clearly knows what the brand story about Tesla’s next decade looks like.

Today’s industrial design can’t solve the dilemma that humanoid robots are not popular, and Tesla is not optimistic. Various cost and scenario application problems will also be an urgent problem for Tesla designers.

The Design Bonus of Sunset Western Hills

In the history of industrial design all over the world, no design team has completely run through the difficult design road of humanoid robots. How to design a humanoid robot? Musk, peter teale and Kai-Fu Lee have no answers, there is no answer in the history of industrial design, there is no answer in bionic design, there is no answer in motor parameters, and there is no answer in data algorithm.

In any case, humanoid robots will always inspire industrial designers deeply: try not to let backward product forms and concepts guide product appearance and creativity.

Jian li, senior product manager of Hetai, believes that the future prospect mainly lies in the service scene function of the companion.Humanoid has never been an efficient productive form, so when designing products, don’t be bound by the evolution process of carbon-based life, so that the efficiency of robots can not be limited to humanoid.

Nina, director of Naiyang’s creative design and operation, said: After the iPhone came out, all the industrial designs of the old era, such as the touch screen slider, disappeared. The category of "smart phone" has also been settled after years of competition. If Tesla’s "Optimus Prime" can become an iPhone-like classic design and have a profound impact on the industry, even if it is wheeled or modularized and detachable, it is very different from the "humanoid" imagined by consumers. As long as the market opens, everyone will slowly accept the new design.

Before the design proposition of human modeling, not only Tesla designers, but also product designers all over the world may be thinking: can humanoid robots get rid of the unnecessary conceptual constraints and break the original appearance ideas?

The answer to this design proposition will probably affect Tesla and other humanoid robots in the next decade or even twenty years.

From the 7th, the autumn in the central and eastern regions will be crisp, and the lowest temperature in the northeast will fall below 10℃.

  CCTV News:According to China Weather Network News, due to the influence of cold air, from today (7th) to the weekend, most of the central and eastern regions are "autumn". The lowest temperature in Harbin, Changchun, Shenyang and other places will fall below 10℃, which is the first time in the second half of this year, and it will be cold in the morning and evening. The sultry weather in the south will also be swept away, and the highest temperature in most areas will be less than 30 C. In terms of precipitation, there are still scattered heavy rainfall in Jiangnan and South China today, and the range of heavy precipitation will retreat to the southeast coast tomorrow.

  The lowest temperature in Northeast China will fall below 10℃, or the local frost in Heilongjiang and Inner Mongolia will be present.

Wechat Picture _20180906160219_ Copy. jpg

  Yesterday, cold air brought strong winds and cool weather to most parts of the north. Monitoring shows that there are 4 ~ 6 winds in most parts of North China, central and eastern Inner Mongolia, Shandong Peninsula and central and western Liaoning, with gusts reaching 7 ~ 9. The temperature in central Inner Mongolia and northwestern Shanxi dropped by more than 10℃ at 14 o’clock yesterday, and the temperature was only about 15℃, which was obviously cool. In Beijing, Tianjin and Hebei, there is also a temperature drop of 6-7℃, but in the afternoon, the sky is clear and the light is strong, and there is still a feeling of sunny and hot.

  Affected by cold air, there will still be 4 ~ 5 northerly winds in the middle and lower reaches of the Yangtze River today and tomorrow, so we need to pay attention to prevention.

  In terms of temperature, from now until the weekend, the highest temperature in most parts of the north is generally less than 30 C, and the lowest temperature is lower than 20 C. The temperature in most parts of North China and Northeast China will remain lower than normal. At present, the front of autumn is roughly in the central part of North China, and the North China Plain has entered the transition period from summer to autumn.

  The highest temperature in northern North China and most parts of Northeast China will be below 20℃, and many places, including Harbin, Changchun and Shenyang, will spend the most obvious day of coolness since the second half of the year. At the same time, the lowest temperature will also fall below 10℃, and it will be cold in the morning and evening. The public should pay attention to adding clothes to keep warm when going out to avoid typhoid fever. On the 8th, the lowest temperature in the north-eastern part of Inner Mongolia and the northwest of Heilongjiang will drop to about 0℃ or below, and the first frost may occur. Agriculture should pay special attention to prevent the adverse effects of low temperature and strong wind.

  The high temperature and sultry weather in the south are swept away, and the weather is "autumn" on weekends.

  Autumn is getting stronger in the north, and there will be a period of cool weather in the south. Yesterday, Chongqing, Hubei and northern Hunan took the lead in cooling down, especially Chongqing, which almost cooled down all the way during the day. At 14 o’clock, the temperature dropped by 15℃ compared with the previous day, only 22.7℃. However, there are still small areas of high temperature weather in Zhejiang, Jiangxi, Guizhou and Guangxi.

20180906093146461_ Cold air cooling _ copy _ copy. jpg

  Today, the high temperature weather in the south will be completely eliminated. Only the highest temperature in Guangdong coastal areas and Hainan is above 30℃, and most other areas will usher in cool weather below 30℃.

  On weekends, the main body of cold air goes south to disperse the rain, and the humidity in many places in the south of the Yangtze River will also drop significantly, and the sultry feeling will be swept away, and there will be a feeling of "autumn" for the time being. However, it will take time to really enter the autumn. The influence of cold air will weaken next week, and the subtropical high will be under control again. After the 11th, there will be another round of sultry weather.

  The precipitation range is reduced, and there is heavy rain in some parts of Jiangnan and South China.

  In terms of precipitation, yesterday, the rain was strong in the eastern part of Northeast China, the central and eastern Sichuan Basin and the southwestern Jiangxi. Monitoring shows that there are scattered rainstorms or heavy rains in northeastern and southern Sichuan, northern and southeastern Chongqing, eastern and south-central Guizhou, eastern Yunnan, south-central Hunan, southwestern Hubei, south-central Jiangxi, Fujian, north-central Guangdong, eastern and northern Guangxi, etc. The maximum rainfall in Yanhe County, Tongren, Guizhou Province is 170 mm, and the maximum hourly rainfall in the above areas is 60 ~ 87 mm; Heavy rain or rainstorm occurred in parts of central and eastern Jilin, central and eastern Liaoning and eastern Heilongjiang, and Kuandian in Dandong, Liaoning was 85 mm.

  Today, the rain in the north has weakened, and most of the south is affected by cold air and warm and humid airflow. It is still rainy, and some areas have scattered heavy rainfall. The Central Meteorological Observatory predicts that there will be small to moderate rain or thunderstorms in northeastern Inner Mongolia, north-central northeastern region, Xinjiang along Tianshan Mountains, most of the Qinghai-Tibet Plateau, most of the southwest region, most of the south of the Yangtze River, southern China and Taiwan Province Island. Among them, there will be heavy rain in parts of southeastern Jiangnan, southern China and central and western Yunnan, with local heavy rain or heavy rain (100-130 mm), accompanied by strong convective weather such as short-term heavy precipitation, thunderstorms or hail.

  Tomorrow, the rainfall in the south will also fade rapidly, and only the southeast coast will still be haunted by heavy rainfall. It is expected that there will be small to moderate rain in parts of eastern Heilongjiang, eastern Jiangnan, central and eastern South China, central and western Southwest China, central northwest China, most of the Qinghai-Tibet Plateau, northwestern Xinjiang and Taiwan Province Island, among which there will be heavy rain or heavy rain in parts of southeastern Fujian, eastern Guangdong, northwestern Yunnan and northeastern Hainan Island, and local heavy rain (100-110 mm).

Extended range car: an innovative journey from germination to popularity

The development of automobiles.

In today’s era of continuous change and innovation in the automobile industry, automobiles, as a unique type, are gradually emerging in the market. It not only has the advantages of environmental protection, but also overcomes the endurance anxiety of pure electric vehicles to a certain extent, which has become the focus of many consumers and automobile manufacturers. Let’s review the development of automobile together and explore its trajectory from birth to gradual rise.

First, the origin of the car. The concept of automobile can be traced back to the early 20th century, when it was in a stage of rapid development, and people put forward higher requirements for the performance and reliability of automobiles. Some engineers began to think about how to improve the fuel economy and environmental protection of automobiles without sacrificing performance, so the new concept came into being.

Early cars mainly added a battery pack on the basis of traditional fuel vehicles, which were driven by electric motors and mainly used to charge batteries. Although this design concept has improved the fuel economy of the automobile to a certain extent, it has not been widely used because the battery technology and motor technology at that time were not mature enough and the performance and reliability of the automobile were not ideal.

Second, the tortuous road of technological development. In the following decades, the development of automobile experienced a long and tortuous road. With the outbreak and the continuous improvement of environmental awareness, people’s demand for new energy vehicles is increasing. However, due to technical and cost constraints, pure electric vehicles and hybrid electric vehicles can not fully meet the market demand for a long time.

During this period, some car manufacturers began to pay attention to cars again and invested a lot of resources in research and development. By constantly improving battery technology, motor technology and engine technology, they have improved the performance and reliability of automobiles. At the same time, the government has also issued a series of policies to support the development of new energy vehicles, providing a good policy environment for the development of automobiles.

Nevertheless, the performance of cars in the market is still unsatisfactory. On the one hand, due to the relatively complex structure and high cost, it is difficult to compete with traditional fuel vehicles and pure electric vehicles. On the other hand, consumers’ awareness and acceptance of cars are relatively low, and many people have doubts about the performance and reliability of this new type of car.

Third, the rise in recent years. Since the 21st century, with the rapid development of battery technology, motor technology and electronic control technology, automobiles have ushered in new development opportunities. Some emerging automobile manufacturers began to take automobiles as their main product direction, and launched a series of competitive models.

Take it as an example, its ideal L series models have achieved great success in the market. These models adopt advanced extended range technology, and the comprehensive cruising range can reach thousands of kilometers, effectively solving the problem of users’ endurance anxiety. At the same time, they also have spacious and comfortable interior space, rich intelligent configuration and excellent dynamic performance, which are favored by many consumers.

In addition to LI, the car series, such as car, also performed well in the market. The appearance of these models not only enriches the product line of automobiles, but also improves consumers’ awareness and acceptance of automobiles.

Fourth, the technical characteristics of the car. The core technology of automobile is range extender, which is usually composed of engine, motor and motor. The function of the range extender is to charge the battery when the battery is low and extend the cruising range of the vehicle. Different from the traditional fuel car, the engine of the car does not directly drive the car, but converts mechanical energy into electrical energy through the generator, and then the electric energy is converted into mechanical energy by the motor to drive the car.

This design concept makes the car have the following technical characteristics:

→1. Long cruising range: Due to the existence of the range extender, the car can charge the battery when the battery power is insufficient, thus extending the cruising range of the car. Compared with pure electric vehicles, cars have a longer cruising range and are more suitable for long-distance travel.

→2. High fuel economy: under urban working conditions, cars can mainly rely on battery to achieve zero emissions; When driving for a long distance, the range extender can work in the most economical condition to charge the battery and reduce fuel consumption.

→3. Good driving experience: Cars are usually driven by electric motors. The characteristics of the electric motors make the vehicle have a quick dynamic response and a smooth acceleration when starting, and there is no sense of shift frustration of traditional fuel vehicles.

→4. Good environmental protection performance: Although the car needs to consume fuel during use, its engine is mainly used to charge the battery instead of directly driving the vehicle, so its emission is relatively low and its environmental protection performance is better.

V. Future development prospects. With the continuous progress of technology and the continuous reduction of cost, the future development prospect of automobiles is very broad. On the one hand, with the continuous development of battery technology, the energy density and cruising range of batteries will be continuously improved, which will further improve the performance and competitiveness of automobiles.

On the other hand, as the government’s support for new energy vehicles continues to increase, cars will be expected to get more preferential policies and subsidies to reduce consumers’ car purchase costs. In addition, with the increasing awareness and acceptance of new energy vehicles by consumers, the market demand for automobiles will also increase. In the future, automobiles are expected to become an important part of the new energy automobile market and contribute to promoting the automobile industry.

In a word, automobile, as a new type of new energy vehicle, has experienced some twists and turns in its development process, but it has gradually risen in recent years and shown great development potential. It is believed that in the future, with the continuous progress of technology and the continuous maturity of the market, automobiles will play a more important role in the automobile industry.

During the year, 182 "recyclable transfer stations" and "bottom recycling" waste glass waste foam boxes will be built, and worthless waste products will also be collected at home.

  Original title: During the year, 182 "recyclable transfer stations" will be built, and worthless waste products from "bottom recycling" waste glass waste foam boxes will also be collected at home.

  Some people collect "valuable waste products" such as cardboard boxes, plastic beverage bottles and scrap metal, but "worthless" waste products such as glass bottles, old clothes and foam boxes are obviously recyclable, but no one who collects waste products is willing to recycle them. According to the Municipal Urban Management Committee, before the end of the year, 182 "recyclables transfer stations" will be built in this city, the main task of which is to recycle and treat "low-value recyclables" such as waste glass, waste textiles, waste foam boxes and large garbage, so as to play the role of "bottoming recycling". This means that "low-value" waste products will soon be sold.

  In Hualong Meiyu Community, the "waste recycling" personnel appointed by residents to manage the country on behalf of the country came to the door. Old cartons, wrapping paper holders, plastic bags for quilts, foam boxes for fresh food, glass bottles … The waste recycling staff sorted the waste that had been saved for more than a month on behalf of the country, and took out electronic scales to weigh it. After weighing and measuring all the waste products, the waste recycler indicated that he would take out his mobile phone on behalf of the country. "A total of 16 yuan, I will transfer money directly to WeChat."

  Like this "paid recycling of waste products", 19 communities in Baizhifang area have achieved full coverage. Zhang Xiaobo, director of the Urban Management Office of Baizhifang Sub-district Office in Xicheng District, said that each community in Baizhifang has set up a garbage sorting station, which can recycle waste products with compensation. In addition, 13 fixed recycling points have been built, and 7 mobile recycling vehicles are equipped. If residents don’t want to go to the recycling point to trade waste products, they can also make an appointment for a recycler to collect them at home, just like managing the country on behalf of others.

  "In many societies, only cardboard boxes, plastic beverage bottles and other recyclables with high recycling value are collected. In addition to recycling valuable waste products, we also recycle worthless waste products such as foam boxes, beer bottles and old clothes. " Yin Bo, director of the operation office of Beijing Jincheng Xinheng Renewable Resources Utilization Co., Ltd., said that the collected domestic garbage can not only be accumulated, but also be transferred by cash via WeChat and Alipay to meet the needs of different residents.

  "In the next step, we also plan to introduce garbage classification points to deduct some property fees, and kitchen waste, other garbage and recyclables can participate in the points." Zhang Xiaobo said.

  Soon, all the recyclable garbage in the city will be collected and disposed of. Wu Runjiang, a third-level researcher at the Solid Waste Department of the Municipal Urban Management Committee, said that in 2021, the city will build another 600 "domestic waste sorting stations". "At present, 339 buildings have been built in each district. In the next step, those that meet the standard requirements will be verified and accepted, and those that do not meet the standard requirements will be rectified. "

  In addition, the city will also build a "recyclable transfer station". Wu Runjiang said that 182 buildings will be built by the end of the year, and now 151 have been built. The main task of the transfer station is to recycle and treat "low-value recyclables" such as waste glass, waste textiles, waste foam boxes, and large-sized garbage, and play the role of "bottoming out".

  At present, the city has built two sorting centers for renewable resources, located in Chaoyang and Miyun respectively. Three temporary sorting centers have been put into trial operation, located in Daxing and Yanqing respectively.

  Wu Runjiang said that in the next step, the city will start with low-value recyclables, introduce corresponding policies and measures, such as giving some necessary subsidies to low-value recyclables, and guide enterprises to promote the classification of recyclables by means of door-to-door recycling, so as to achieve all points and all receivables.

Difference between Ferrari sf90spider and sf90

SF90 Spider is the latest model of Ferrari. It is a roadster. The SF90 is a plug-in hybrid sports car of Ferrari, which is Ferrari’s first mass-produced V8 hybrid supercar.

The main difference between the two is that:

1. The power system is different: SF90 adopts plug-in hybrid power system, which consists of a 4.0-liter V8 engine and three motors; The SF90 Spider uses the traditional naturally aspirated V8 engine, and has no motor configuration.

2. Different appearance: SF90 Spider is a convertible design, and the roof can be folded up at high speed; The SF90 is a hard top design.

3. The performance parameters are slightly different: due to the different power systems, their performances in acceleration and extreme speed are also different. But overall, the performance of both models is excellent.

Compulsory internships that earn "headcount fees" must be curbed.

  [Guangming Times Review]

  Author: Xiong Bingqi (Dean of 21st Century Education Research Institute)

  Recently, the Ministry of Education and other departments jointly issued the newly revised Regulations on the Management of Students’ Internship in Vocational Schools (hereinafter referred to as the Regulations), clarifying that "internships should not be arranged across major categories", "students should not be arranged to engage in simple repetitive work", "students should not be arranged to engage in manual labor of Grade III intensity or above or other internships harmful to physical and mental health" and "it is strictly forbidden to organize internships illegally for profit".

  As early as 2016, the Ministry of Education, the Ministry of Finance and other five departments jointly issued the Regulations on the Management of Students’ Internship in Vocational Schools, which played an important role in regulating students’ internship in vocational schools. However, in recent years, there are still some problems in some areas, such as organizing students to work in the production line of enterprises in the name of internship, arranging overtime and night shift, compulsory internship, fee-based internship, and mismatch of internship majors.

  The compulsory practice of earning "headcount fee" is nominally "school-enterprise cooperation", and the essence is to treat students as cheap labor. Schools charge management fees by exporting labor services to enterprises, while enterprises fill the labor shortage with student labor services. Most of the enterprises that vocational colleges force students to practice are low-end labor-intensive enterprises. It is difficult for these enterprises to recruit workers through the labor market and turn to schools for "cooperation" to obtain cheap labor. Students are arranged to do assembly line repetitive work unrelated to their majors, which not only infringes on students’ rights, but also misleads students’ understanding of vocational education and skilled personnel. Many students have not learned skills and think that skilled personnel have no way out. The existence of this kind of low-end practice actually hinders the improvement of vocational education quality and affects the image of vocational education.

  The revised "Regulations" focus on curbing the compulsory practice of earning "headcount fee", protecting students’ legal rights and improving the quality of practice. To implement the Regulations, in addition to improving the accountability mechanism, we must seriously blame the off-campus vocational colleges that illegally organize internships, we must also strengthen investment in vocational colleges, eliminate backward enterprises that have been unable to recruit laborers from the labor market, and promote the establishment of a modern vocational college system to carry out high-quality integration of production and education.

  For the illegal organization of student internships in vocational colleges, most of the current treatments are just to stop illegal internships, without further treatment and accountability. In this regard, we should increase the punishment, blacklist the schools that illegally organize students’ internships, disclose the school’s illegal behaviors to the public, reduce its enrollment plan or even revoke its qualifications for running schools.

  In addition to the relevant personnel profiting from it, there are also vocational colleges that illegally organize student internships as a way to obtain school funds and improve teachers’ treatment. In recent years, some intermediaries have also seen this demand in vocational colleges and intervened to organize student internships as business opportunities. Regarding the participation of intermediary agencies in students’ internships, the Regulations specify that the tripartite agreement on internships must be signed by vocational schools, internship units and students, and reiterate that students’ internships cannot be organized, arranged and managed through intermediaries or paid agents. The warning significance of this is that institutions that enter the field of vocational education can’t make profits and take organizing student internships as a business. The school’s self-"labor intermediation" is more worthy of attention. In this regard, it is necessary to increase investment in vocational colleges, improve the treatment of vocational school teachers, and let schools concentrate on running schools.

  Practice is an important link in the practical teaching of vocational school students, which is not only a necessary way for professional learning and technical skills training, but also an important way to temper the will quality, get familiar with the post in advance and guide integration into society. In order to achieve the goal of practice teaching, it is necessary to eliminate the practice of working in the post.

  In the final analysis, organizing students’ internships in vocational colleges is an educational matter. To avoid vocational schools sending students to work in enterprises that do not have internship conditions, it is necessary to play the role of the school professors’ committee, which makes internship teaching plans, selects qualified internship enterprises, designs internship teaching contents, supervises the internship teaching process and evaluates the internship teaching effect. This is the key to establish a modern vocational college system and to improve the quality of running a vocational college.

  Guangming Daily (January 27, 2022, 02 edition)

China is the country with the largest amount of marine plastics. How can plastic waste be discharged into ocean currents?

Several ways for plastic garbage to enter the ocean;

1. Dump directly into it. For some plastic wastes with no recycling value, in order to reduce the cost, they are either directly burned or dumped into rivers and finally merged into the ocean. This phenomenon is particularly common in rural areas of China, and at present, the treatment capacity of landfill sites in China is mostly saturated, and there is no matching treatment capacity with a large number of plastic wastes. In addition, some of them are daily garbage produced by human life, which are randomly discarded in rivers, beaches and the sea due to the incomplete recycling system and the lack of environmental awareness. The widespread use of disposable plastic packaging aggravates this situation, and the related garbage collection system may be underdeveloped or even non-existent.

2. Sewage outlet. Mainly discharged into rivers through sewage pipes of sewage treatment plants. The waste water of industrial products may contain plastic particles, and in some places where supervision is not strict, large pieces of plastic waste may be directly discharged with the waste water through the sewage outlet.

3. Secondary pollution caused by improper garbage disposal

(1) landfill leachate pollution caused by improper landfill. The plastic particles contained in these leachate will penetrate deep into the soil and pollute the groundwater. The groundwater and the water flow in inland lakes are complementary, and these polluted groundwater will enter the river through the lake and finally flow into the ocean.

(2) Non-standard treatment of plastic recycling family workshops in China. In these small workshops, it is often necessary to use a lot of clean water to clean plastic waste, and these plastic-washed wastewater will not be treated harmlessly, so it will directly carry a large number of plastic particles or even whole pieces of plastic into the river. Like these sewage, the remaining plastic garbage residues will be directly dumped on the river bed.

4. Maritime activities

Including marine aquaculture and fishing, exploration and development, all kinds of garbage and ship coatings discharged during the ship’s driving. Some large-scale maritime accidents, such as capsizing of ships and leakage of raw materials, will also lead to plastic waste entering the boundless sea.

What impact will plastic waste have on the ocean?

People call the plastic garbage floating on the ocean the "seventh continent" as a whole, and plastic pollution has become the "unbearable weight of life" for many marine creatures in the vast ocean.

The harm of plastics to wild animals is unimaginable to human beings.

Maybe you never thought that the plastic rope you threw away would sink into the sea and entangle with countless marine life. It is reported that at least 344 species have been caught in the pain of being entangled with plastic so far.Including all turtle species, more than two-thirds of seal species, one-third of whale species and one-quarter of seabirds.

The seemingly dazzling and exquisite packaging plastic paper is also "hidden" after flowing into the sea. Most marine life has eaten plastic fragments by mistake. According to the records of the media and related institutions,At least 233 marine species, including all turtle species, more than one-third of seal species, 59% of whale species, 59% of seabird species, 92 species of fish and 6 species of invertebrates, have ingested plastics..

In addition, touching or colliding with plastic products can also threaten the lives of marine animals. For example, fishing gear has been proved to cause wear and damage to coral reef ecosystem during collision.

The report "Marine Garbage: Understanding, Preventing and Mitigating the Adverse Effects on Marine and Coastal Biodiversity" issued by the Secretariat of the United Nations Convention on Biological Diversity collates the field investigation of polluted marine organisms since 2012. The report shows that plastic pollution has involved various marine biota such as fish, algae, marine birds, marine mammals and marine reptiles.

To make matters worse, plastics are encroaching on the habitats on which marine life depends at an alarming rate. UN Secretary-General Guterres pointed out that pollution, overfishing and the impact of climate change are seriously damaging the health of the oceans. He said that according to a recent study, by 2050, the total weight of plastic waste in the ocean may exceed that of fish.

Marine plastics are difficult to degrade.

Plastic is a synthetic macromolecular polymer, and its molecular structure is difficult to be destroyed by biodegradation. If plastic is to be completely degraded into small molecules, a large number of chemical bonds need to be completely broken. For polyethylene molecules, this requires a lot of energy. Therefore, it may take hundreds of years to completely degrade plastics. A BBC report mentioned that a plastic cup can "survive" on the earth for half a century, which shows that the degradation of plastics is very difficult. Unlike land, the refrigeration effect of seawater slows down the degradation process caused by sunlight and high temperature. Therefore, the process of comprehensive decomposition of marine plastic waste is more long and arduous.

-It is difficult to recycle marine plastics.

The vast majority of monomers used to make plastics, such as ethylene and propylene, come from fossil hydrocarbon maps. None of the commonly used plastics is biodegradable. Plastics will eventually accumulate in landfills or natural environments rather than decompose. The only way to permanently eliminate plastic waste is through destructive heat treatment, such as combustion or pyrolysis. Therefore, the near-permanent pollution of the natural environment with plastic waste is an increasingly serious problem. Plastic fragments have been found in all major ocean basins, and it is estimated that the plastic waste entering the marine environment in 2010 alone reached 4-12 million tons. Fresh water system and terrestrial ecological environment are increasingly eroded by plastics.

Nowadays, plastic waste is everywhere.

Sea water is flowing, and plastic will drift to all directions with the water flow; Seawater is also unfathomable, and plastics with different weights and qualities will be divided into different depths. No matter how hard people try, there is no guarantee that there will be no more plastic in the seawater of a certain area. When the plastic is turned into tiny particles, things become more complicated, the difficulty of recycling suddenly increases, and the harm is even greater. 

-There are limitations in monitoring marine plastics

1. There are disputes about the data model and sampling method of plastic waste.

A few days ago, a number of experts and scholars announced their monitoring results of microplastics off the coast of China at the APEC seminar on innovative ways to prevent and control marine debris. Although the monitoring scope is the same, their data results are quite different. Luo Yongming, a researcher from Yantai Coastal Zone Research Institute of Chinese Academy of Sciences, said that this is due to the differences in sampling tools and methodology.

Not only are there great differences in domestic research results, but the sampling and research methods of marine plastic waste have not been unified internationally. Li Daoji, a marine environmental expert, once pointed out that the international model research on the amount of marine plastic waste has not measured the amount of plastic waste discharged by various countries, and the research method is still open to question.

2. It is difficult to monitor and treat marine plastic waste.

It is very difficult to track the input and distribution of marine plastics, and there is a great difference between the annual input of plastics and the ocean and the estimated value of surface plastic accumulation. This difference is called the "missing plastic" problem. The monitoring of microplastics is even more difficult, because the particle size of microplastics is very small, and the analysis is very difficult. Therefore, the economic strength of different research teams, the ability to obtain data, the advanced analytical instruments and the feasibility of analytical technology will all have an impact on the monitoring results, which leads to great uncertainty in the monitoring of marine microplastics.

Therefore, it is unrealistic to try to clean up all the plastic garbage in the ocean by manpower. What human beings should do is how to reduce the production and use of plastics, improve the recycling and utilization rate of plastics, and control the source of pollution.

Tens of billions of years ago, the first single-celled life on the earth was born in the ocean, but there is no doubt that these white ghosts created by ourselves are slowly destroying the source of life. It is difficult for us to predict where the plastic bottles we throw away will float, just as we can’t predict what node these plastic wastes will bring to the fate of six billion human beings.

Boxster’s past lives. It brought Porsche back to life.

  [History of car home Cars] Today, Porsche is one of the most profitable car manufacturers in the world. However, in the 1990s, it suffered a serious crisis and almost went bankrupt. How did Porsche get out of the predicament step by step and realize its legendary revival? Among them, (|), the two-seater roadster to be discussed in this paper, plays a decisive role.

Home of the car

  In the early 1990s, although Porsche owned three models, 928, 911(964) and 968, the sales situation was not satisfactory, which caused the company to fall into a terrible business crisis. In order to save the enterprise, Porsche has carried out drastic reforms. On the one hand, Toyota production mode is introduced to save costs and improve production efficiency.

  On the other hand, adjust the product range, stop production of the expensive 928 and 968 equipped with front-mounted 4-cylinder engine, and instead develop a sports car with more attractive price that can capture the hearts of young consumers. In addition, in order to raise more funds, Porsche and Audi jointly built a high-performance station wagon RS2 and designed a sedan C88 for the China market.

  In 1991, Porsche, which was in deep crisis of survival, tried various solutions, including a two-seat convertible concept car with a mid-engine layout-Boxster. The design of the car was inspired by the concept car Panamericana built by Ferrari Porsche on his 80th birthday. The short rear suspension and short body, the front suspension extending forward and protruding from the front axle and the exhaust tailpipe arranged in the center of the rear of the car continue the classic design of Porsche.

  Boxer is a combination of the words "horizontally opposed engine" and "roadster". This name contains the initial setting of horizontally opposed engine, which is also a prominent technical feature shared by the 356 models launched in 1948 and the 911 models from 1963 to the present. The concept of mid-engine is derived from the predecessors 550 Spyder, 914/6 and 718 racing cars.

Home of the car

  Boxster concept car is equipped with Porsche’s first mass-produced water-cooled horizontally opposed six-cylinder engine, with an initial displacement of 2.5 liters and a maximum power of 204 HP. Because of the water cooling system, four valves and variable intake timing, its design meets more stringent emission standards. The car’s innovations also include a balanced weight distribution, a quick-opening movable roof, a braking system derived from racing, and the best drag coefficient (Cd=0.31) in its class.

Home of the car

  The research and development work is in full swing. According to Grant Larson, the designer in charge of Boxster concept car, "We originally planned to show our concept car at the Geneva Motor Show in the spring of 1993. But we decided to choose Detroit in January because we didn’t want to waste any time. More importantly, our focus on sports cars was on the American market, when Porsche did not perform well in the American market. Mazda Miata and BMW Z1 have already appeared in the market. "

Home of the car

  The Boxster concept car unveiled at Detroit Auto Show was very popular. "Boxster received overwhelming praise from the public and experts, which obviously had an impact on development," Grant Larson continued. "Shortly after the exhibition in Detroit, we were asked to stop the design and development of Boxster immediately, and instead, we were asked to produce it as a concept car!" Time has proved that this is a wise decision.

  In October 1996, Porsche Boxster was officially released, which filled the gap of entry-level models below 911. It is worth mentioning that Boxster is not only manufactured in Zuwenhausen factory in Stuttgart, but also subcontracted to Valmet company in Finland, which is the first time that Porsche models have been produced outside Germany since the early Austrian factory.

Attention! This "subsidy" must not be received!

"Individual labor subsidy in the fourth quarter of 2023"

It has been distributed now.

Please scan the QR code for authentication and collection immediately.

Near the end of the year

Receive such an e-mail

Don’t get it yet!

This is a new trap for swindlers! !

Real case

Recently, Ms. Lou (Hua’s surname) of Chengxiang Street in Xiaoshan received an email entitled "Application for Personal Labor Subsidy in 2023" at home, which required "scanning the QR code registration information in the document and receiving the labor subsidy for on-the-job personnel." Ms. Lou didn’t think much, scanned the code and opened the link, and filled in personal information such as ID number and bank card number as prompted. However, when she filled in the verification code and payment password, she received a debit message from the bank, showing that the deduction was 6900 yuan, and she realized that she was cheated.

Routine analysis

Step 1: Send fake mail.

Liars illegally embezzle the mailboxes of internal managers of enterprises and send emails to employees in batches. The contents are official documents of relevant government departments on issuing "labor allowances and subsidies" with QR codes attached.

Step 2: Induce to fill in personal information.

The swindler induces the deceived person to scan the code and log in to the fraudulent website, click "Confirm Collection" on the page, and fill in personal information such as ID number, bank card number and bank card balance as prompted.

Step 3: Induce the input of verification code.

After the deceived person receives the short message of the bank’s verification code, he is induced to input information such as verification code and bank card password to steal the balance in the victim’s card.

1. If you receive an email similar to "scan the QR code to receive subsidies", check with the relevant departments of the company in time, and don’t believe it easily.

2. Don’t scan the unknown QR code at will, and protect personal information such as ID number, bank card number, balance and mobile phone verification code.

3. In case of online fraud, keep relevant evidence materials such as chat records and transaction records, and call 96110 in time.
