Ever dreamed of patenting a great idea that could make you a fortune? The Pet Rock maybe? Or the Jump To Conclusions mat? Well, you'll find even more crazy ideas using Google Patent Search , or even better, submit one of your own.

I've only been buzzing around on Google's patent search engine for a few minutes, but I have already found some very unusual and unique inventions. For the sake of Wisebread readers, I thought I'd look for inventions about saving money, time and hassle. I found thousands. Here are just a few of my favorites.

1: The Compartmented Piggy Bank

2: A space-saver pizza box (nice)

3: A wine & spirits carry-out package

4: A briefcase that converts into a table

5: A split-ends remover (not much use for me, I shave my head)

I'm sure you'll have something more specific in mind when you're looking around. Maybe it will inspire you to invent something of your own, and file a patent. With over 7 million already out there, you've got some competition. But who knows, maybe your idea will be the next iPod. Go for it.

Oh, and speaking of inventions, check this one out. A fridge that throws you a beer. Nice.
