You really need to find a domain expert who can at least get you started. I'm working on a problem that I would not have even known existed, if not for running across a couple of engineers who had a business in the field and saw an opening that only a small company would care about (market isn't big enough for the large players).

I know similar situations have to be all around us. The problem, as you say, is finding out about them.
