Innovation is anything that is new, useful, and surprising. "Surprising" means that the idea makes you slap your forehead and say, "Gee, why didn't I think of that?" Here's a great example.

It is a classic and clever example of the Divison Technique, one of the five techniques in Systematic Inventive Thinking.
