A heuristic-based approach to conceptual design

In the inherently large space of design, explicating all possible concept variants—to avoid leaving out potential concepts—is astronomically costly, if at all possible. A strategy that can assist designers in exploring and ascertaining design solutions within this vast space is therefore crucial. This work adapts a general best first heuristic algorithm for applications on conceptual design problems. The algorithm is tailored to operate on a model of conceptual design postulated in this paper. The propositions are established by an ordered series of formal definitions and mathematical assertions, which characterizes the complete theoretical model. Via a simple design case study, this product conceptualization approach is demonstrated to strategically guide designers in the exploration of design concepts.
