Name this inventor / designer

A colleague was describing a designer, but left out a lot of details.

As it was described to me, the designer took one thing, object, process, tool from his everyday life, each day. He would then redesign, or invent something to make this ‘thing’ better. Apparently he ended up inventing something that most of us use every day, but my colleague can’t remember that either.

Any ideas ?

I don’t know, but it sounds like the sort of thing that Buckminster Fuller would have done.

Just where is my Dymaxion Bathroom?
