Creative/inventive dreams

So I had this crazy dream about a bondage toy that I’d made up completely, I’d never seen such a thing before I did some research and found there’s nothing quite like what I managed to conjure up in said dream, usually my kinky dreams are simple light bondage but this one was rather heavy and I was a fan! I’d love to be able to make the item but I’m not that good with designing something myself! Now I know lovehoney have the design a sex toy thing going on, but there’s the part of building a prototype that I couldn’t pull through. Which is gutting because I’m certain what I came up with would fly off the shelf’s for those who enjoy clamps and restriction! I won’t write it here but I would love to know if anyone can suggest a way I can propose the idea to someone making it without me building a prototype.
