I agree with "MJL927" on the patenting part .But that like he said needs $$$, and stile after you pay the atturny you haven't started yet .I sugest you try to sell the design to a company work in the filed or one of those companies who look for new enventions to produce new products.before you show them any thing you make sure they sign a desclimar not to produce without paying you.
if you think it works go for it there are lots of companies are just looking to make new $$$ from new products.
best luck
