How does the text differentiate the definitions of a Design Engineer versus a Chemical Engineer based on their modifiers?

Answer

A Design Engineer is defined by the function (designing), whereas a Chemical Engineer is defined by the domain (chemistry/process).

The differentiation lies in the naming convention: Design Engineer describes the primary action or role performed, while Chemical Engineer describes the area of scientific study or industry specialization that defines the work.
