Just go ahead and say you’re conceiving ideas about conceiving ideas! Haha.
I don’t think you need to think of your driver itself as conceiving an idea. Your driver just needs to be an action or decision. Conceiving is what is creating conflict between story drivers. Your driver is what drives the story into the next act, the next perspective on the conflict.
It’s announced that the Americans have launched a missile (action driver) which forces the Russians to decide how to respond-strike back? Take cover?-but when one man has trouble conceiving that they are being attacked, he can’t bring himself to push the button to launch a counter strike (an attempt at SP of Conceiving-it could probably be stronger). The man steadfastly refuses to push the button (solution). The higher ups call and congratulate the man for keeping calm and not pushing the button when a glitch in the system made it look like the Americans had attacked (final action driver that ends the need to decide how to react and ends the exploration of the problem)
Probably not the strongest example, there, but that’s kind of how I would use everything.
