Israelis have invented a smart wheel
The Israeli start-up Softwheel has created a self-cushioning wheel that can make life a lot easier for wheelchair users and cyclists. A wheelchair with these wheels can be ridden up and down stairs thanks to a built-in mechanism that can absorb shocks when hitting obstacles.
As the inventors themselves explain, when the wheel rides on a flat surface, it behaves like an ordinary rigid wheel. However, if the wheel encounters an obstacle above a predetermined threshold, it "softens" and dampens the impact. The softness threshold can be changed to suit the owner's needs.
