If there’s anyone out there who’s had a “Why Didn’t I Think of That?” idea before– some product or invention that you know is a good idea, but you just don’t have the time to actually, well, invent it– here’s your chance.

It’s just good timing that this came along during our month of covering unique inventions. It’s called “Firebox Inventor,” and it’s a search for “inspired ideas for new products.”

According to the website, Firebox, in accordance with Stuff, is conducting “a national search to find the next must-have product for 2010 and it might just be your idea that makes it onto our shelves! It could be a cool new toy, handy gadget, or something else entirely: if it’s original and it fits our quirky range, we want to hear about it.

You don’t need to have an expensive prototype, polished business plan, or to take part in a scary formal pitch.”

“There is no age limit to this competition and no experience necessary. Your product suggestion could take the form of a drawing, photo, video, or doodle on a beer mat. Whether it’s a long email, a short tweet or arrives by carrier pigeon; any entry format goes.”

If you win, your product will be developed, manufactured and sold by Firebox on their website. And you’ll get 50% of the profits too. A good deal, if you don’t mind giving away one or two of your great ideas.

My suggestion? Give it a shot. And let me know how it goes. You can find out more at their website:  http://www.firebox.com/features/inventor.

Good Luck!
