Is reinventing the wheel really a bad thing

As the old saying goes, "don't reinvent the wheel". We say this in reference to not work too hard to do something that has already been done. However one man decided to try to reinvent the wheel. and what he got was a new wheel that is very practical and completely innovative. Duncan Fitzsimmons created a new wheel called the Morph. The Morph is a detachable wheelchair wheel that can compress to around half of its original width. It is designed to provide greater flexibility and mobility to the estimated 65 million people around the world who need a wheelchair. Anyone who has ever tried to move a wheelchair knows that even when folded they take up a large amount of space.
