True Lego changes the world! Children can also use it to design their own prostheses ｜ Feel Good Weekly

How can in-situ printing of turbine blades change the world with Lego? This book gives interesting answers.

　　When people say "Lego can build anything", I think it's just a rhetorical statement.

　　But a book recently put on the shelves of Lego official website changed my mind.

　　This book, Lego Heroes, tells the story of 12 innovators who used Lego to "change the world".

　　The first character in the book is the designer Carlos Arturo Torres.

　　When communicating with Dario, an 8-year-old boy whose right arm is missing, Torres realized that only children know what they need, so he thought of applying Lego to children's prosthetic limbs so that children can build the components they need.

　　Torres finally made a prosthetic system called Iko, which has a built-in battery, a processor and an electromyographic sensor that can detect muscle movement. Children can build any Lego design according to their own needs and connect it to the Iko system.

　　In addition, this book also records how people use Lego to make a wheelchair for injured turtles, create Lego bricks in Braille, and use Lego to study coral reefs.

　　MUJI rebuilt the electric car, and this time it also used recycled plastic.

　　Some time ago, MUJI stores in Taiwan Province began to put away "waste products".

　　It turns out that this is a "Recycling for Good" activity initiated by MUJI and Gogoro, a local electric vehicle brand in Taiwan Province, inviting consumers to take useless PP (polypropylene) plastic waste to the stores of the two brands for recycling.

　　Next, these recycled products went through "screening, screening, cutting, granulating, remodeling and regeneration", and finally became the body panel of the newly designed electric vehicle.

　　This time, in addition to joining hands with Gogoro, MUJI invited naoto fukasawa, one of the designers who defined the "MUJI style", to jointly build two electric vehicles, Gogoro Vivames and Gogoro VIVA MIX ME.

　　For this project, naoto fukasawa said:

　　In the design, the most important thing is that it must have the spirit of honesty to people, the environment and life.

　　As always, these two electric vehicles inherit the minimalist aesthetics of MUJI, and adopt simple design and soothing and elegant color matching.

　　When asked why recycled PP was chosen, MUJI said that PP is "the most heat-resistant plastic" and "durable and not easy to react with water and chemicals", and recycling is easier.

　　Muji said that this is why brands also choose PP as raw materials when making storage containers.

　　Previously, MUJI cooperated with Honda to launch an electric car in 2022, and the overall design was more compact.

　　Let more people fix it, and Xbox has also started selling spare parts.

　　Recently, Microsoft officially launched a batch of Xbox spare parts in official website, North America. Users of Xbox Elite Series 2 and Xbox Wireless Controller can do it themselves.

　　Accessories on the shelves this time include: handle shell, various buttons, printed circuit boards, etc. The price ranges from 19.99 to 59.99 US dollars (about RMB 144-430 yuan), and the warranty period is one year.

　　In addition, Xbox also released a detailed "Xbox Controller Safety and Maintenance Guide" and a video version of the maintenance guide, even if you are not a professional, you can follow the maintenance step by step.

　　In recent years, more and more people are seeking to regain the "maintenance right".

　　In the digital age, due to the limitation of software or hardware, we can only have the right to use electronic equipment, but we can't repair it or even give it to others.

　　The "Maintenance Right Movement" is an attempt to change this situation, advocating that large companies should consider the maintainability of products when designing products, and consumers should also get more information when consuming.

　　At the same time, products that can be repaired and can find repair parts mostly mean longer service life and less waste, which is also in line with the concept of sustainability.

　　In addition to this Xbox accessory, Microsoft has previously introduced replacement parts for Surface devices. Last year, Apple also launched a self-service maintenance program for the public, allowing users to purchase maintenance parts and tools by themselves.

　　OPPO Announces "Smile Proposal" China Roadshow TOP 5

　　The "Smile Proposal" is a science and technology innovation and empowerment platform initiated by OPPO Research Institute. Focusing on the brand mission of "Science and technology serve people and make the world better", it collects and empowers innovative technology solutions for the whole world.

　　The theme of the Smile Proposal in 2023 is "Innovation for Good", which consists of two topics: "Science and Technology for People" and "Green Future".

　　Recently, according to the four dimensions and 15 detailed rules of "application landing", "technological innovation", "long-term development potential" and "social public value", the judging panel finally selected China's TOP 5 proposal to enter the global final roadshow.

　　In October this year, the TOP 5 proposal in China will participate in the Smile Proposal Acceleration Camp together with TOP 5 roadshows in Boston, USA and Bangkok, Thailand, and have in-depth exchanges with OPPO executives, technical and investment teams and industry partners, and enter the global finalist roadshows.

　　The TOP 5 proposal that finally wins in the final will receive a bonus of RMB 350,000, and have opportunities for business and technical cooperation with OPPO and its partners.

　　Orbital Composites: how to reduce the cost of wind power? In-situ printing turbine blades

　　It is not easy to transport the wind turbine to its destination, and it may take a year to plan it alone.

　　If you encounter a mountain road, it may take two weeks to transport a 60-meter-long wind turbine blade.

　　Orbital Composites, a startup, has come up with a new idea-why don't we print the blades in situ where the wind turbines are used? This will reduce the trouble of transportation.

　　Orbital Composites' technology can print composite materials at high speed, and drones and satellite components have been printed in 3D before.

　　Applied to wind turbine blades, the team needs to print a huge mold in 3D first, and then print the blades in this mold.

　　Surprisingly, the materials used in the above work can be packed in containers, which makes transportation easier.

　　Later this year, Orbital Composites will use 30-meter-long blades to test the effect, and then continue to test 50-meter-long blades.

　　To add to the icing on the cake, 3D printing saves more materials than traditional production processes, and in the future, Orbital Composites can also print blades with recyclable materials:

　　Not only can we reduce the use of raw materials from the beginning, but we can also recycle these materials and reuse them downstream.
