Routine design problems solved by methods well known within the specialty. No invention needed

Minor improvements, by methods within the industry. Usually with some compromise

Fundamental improvements by methods known outside the industry. Contradictions resolved

New generation principle to perform primary functions. Solution found in science than in technology.

A rare scientific discovery or pioneering invention of essentially a new system
