Problem Solving
By deriving these networks of relations among these objects and their physical properties, the functions of the objects are transformed in a manner that allows the goal (turning the screw) to be achieved.

In the proper sequence, these functions combine to give the toothbrush the entirely new function of screw-turning. Problem solved!
