I am opting towards the rachet type things however, could someone show me an example of how to disengage the pawl?

I'm not really sure how I could setup a rachet and pawl so that it wouldn't want to unwind the motor as my cable unwinds.
Care to elaborate? I was trying to think of a realworld machine that uses something like this, but I have come up with nothing.
I'd think a simple servo with its output linked to the pawl could work rather well as a disengaging mechanism. Also theres always the option of a small pneumatic cylinder, but i'd figure that'd be overkill.

Heres a simple paint drawing to help illustrate (literally) my idea
