12.4 Expand the Concepts and Develop the Concept Fragments

Expanding the Propulsion Function

In Chapter 7, we noted that concepts can often be broken down into constituent ideas, which we call concept fragments. Step 2 in creating the concept is to expand the concept and develop ­fragments. For the Hybrid Car, the specific process we identified is driving—a concept rich in meaning! In order to expand this concept, we are going to decompose the driving process to identify concept fragments. We begin with the concept fragment of propulsion as one of the constituents of driving, and then we will examine seven additional concept fragments.

Specifically, we will categorize hybrids first by how their propulsion systems are combined. Three types of ...
