These inventions are incredible! Why? Because they are based on lived experiences (like old age) and needs (like the need to get out of a building fast). Because they function so well for the places and activities of daily life. AND because they are so beautiful! The combination wheelchair foldable bike is genius (exercise for the caregiver)! And who doesn’t want (need) a bike that is able to carry us over water as well as land as we commute to work? And that evacuation slide? It’s a work of art! Wouldn’t it be awesome in the MOMA?
83-year-old Zhang Yongqing shows off his invention, a combination of a wheelchair and foldable bicycle. Zhang said he invented the multifunctional bicycle so that care-givers can take better care of wheelchair-bound elderly people.
Lei Zhiqian rides a modified bicycle across the Hanjiang River. The bicycle, equipped with eight empty water containers at the bottom, was modified by Lei’s instructor Li Weiguo, who hopes to put his invention into the market.
70-year-old inventor Zhou Miaorong tries out an evacuation slide he built himself in a building in Shanghai,. Zhou took over two years to design and build the mechanical slide which uses no electricity to implement in a domino effect, while also triggering a sprinkler system to fight a fire.
