| Keywords: C2C strapon quad roller skates.png en A schematic showing a cradle-to-cradle quad rollerskates concept This concept would improve the manufacturing method and also makes the skates modulatable This means that a same skate can be kept even as the foot grows as the person using the skate gets older For this the wheels and X-frame are kept and a different metal sole+rubber/plastic sole is attached by screwing another one on The metal+rubber/plastic sole that has become too small can be brought back to the shop and reintroduced to the market circuit Note that plastic would only be a viable alternative for the top sole if it has been recycled; no new plastic should be made to produce the sole Also the paint layer would be composed of biodegradable matter; no undegradable paint can be used The design was done by User KVDP own KVDP 2010-04-25 Concepts Appropriate technology Industrial ecology Sustainability | ||||
