Soccer, a/k/a football is a popular children's pastime around the world, particularly in developing nations. A patch of ground, the ball, and improvised goal posts are the only infrastructure required. Should the ball deflate, however, an air pump is required; should the ball be punctured, it's worthless.
To solve this, Nendo has designed a soccer ball that doesn't rely on air pressure to hold its shape, requires no inflation, and therefore cannot be deflated.
Instead, their design is composed of three different types of interlocking components, 54 pieces in total. The bands and structural inserts are made of recycled polypropylene, and the pentagonal exterior panels are made from softer EVA (ethylene vinyl acetate) for cushioning.
The product ships flat, meaning more units can be fit into a shipping box versus a conventional ball.
The end user must assemble the ball by referring to an Ikea-like language-free instruction manual.
Once assembled, the ball is soft enough for bare feet, and is "unlikely even if broken to develop a sharply fractured surface that might cause injuries," Nendo writes.
They reckon the ball is also durable enough to take a pounding--and in the event that a section of the ball becomes damaged, it can be replaced (assuming there's an infrastructure/ordering process for replacement parts).
