A Systematic Approach to Conceptual Design

Abstract

The issue in conceptual design theory is to understand the processes which lead to innovation and to create tools which generate step changes in function in an orderly and repetitious manner. Detailed synthesis methods which generally follow the conceptual phase of the design process require input specifications. An extension of function logic is proposed as a means to promote innovation systematically, manage conceptual design information, and produce such specifications. A three-tiered model for conceptual design is presented comprising function structure, allocation, and components. Applications of the model are given to include design intent, information flow, functional vanants, and system behavior. Detailed examples are given with references to current methods.
