Google's keyword tools are there to help webmasters decide what keywords to target, not the other way around. You can't force people to all of a sudden start searching for a specific keyword. If people currently aren't searching for a keyword or phrase it could be for several reasons. One reason could be that it's something so innovative that it doesn't exist yet. Another reason could be that it's just not a natural way of phrasing something.
However, whatever the reason is for the lack of use of that keyword or phrase, the fact remains that people don't search for it.
My advice is to forget about that phrase no matter how great you think it is, and come up with one that people actually do search for that has low to medium competition.
