Conceptualization

Conceptualization is the building of a mental picture or the construction of an idea or theory.

An example of this could be an engineer mentally visualizing a machine or device that is needed to solve a problem. Imagine the Wright Brothers visualizing what was needed to invent a flying machine and trying to merge the physics of flight with the mechanics of a machine - this was a conceptualization of their idea. Another fascinating example are the concept designs made by Da Vinci centuries ago that devised weapon systems that the technology of the time couldn't yet use.
