Inspiration flagging?

The last couple of days I've been having a rather difficult time working on a paper I need to get out by the end of the month. The problem is that the ideas for how to combine the two rather disparate concepts I want to describe is rather challenging, yet it really needs to be done.

I'm not sure how this will happen, but usually some rather blatantly obvious oversight usually is the culprit behind these cases of writer's block.
