The innovation process has been fairly well codified by a lot of research. And they pretty much proved the bleeding obvious:
A strong, well defined problem really helps you to create successful innovations.
Most people tend to jump to solutions first, but you still need that defined problem in order to sell the idea to investors and the product to customers.
Or in other words, you can have the best solution in the world, but if that problem doesn't effect enough people badly enough, you haven't got a viable business.
So if your problem is "people want to wash their bikes without electricity" you might be looking at a small eco-mentalist market.
If it's "people want to wash their bikes without electricity, using any water they've got, for a third of the price of a dirtworker, and also don't want to have to lug a 15 litre tank of water around" then you've suddenly made things a lot broader.
