James Dyson designed and manufactured a wheelbarrow that was harder to over-balance. It had a ball instead of a wheel. And it didn't bite into the mud in the same way as a wheel. It was called the Ballbarrow.

At one point the paint-spray booth extractor needed maintenance and when he took it apart they discovered the main collector was a cylinder and Dyson being an inventor saw immediately it worked as a centrifuge. The leap to vacuum cleaners was pretty swift. That's how inventors' minds work.

That's why he champions creativity and invention.
