Abstract

Product development can be considered as the evolutionary and iterative process of recognition, formulation, and satisfaction of constraints. These constraints become the rationale driving the design to the final specifications, while the evolution of constraints reflects the design process, and embeds decisions made by designers through the iterative process. This paper proposes an approach to integrate a constraint-based approach and mark-up of a CAD model, so as to allow the designer to annotate the product model with the design constraints, and which can then be used to optimize the design by monitoring, satisfying and adapting the constraints. The paper also proposes that the evolving constraints can be used to retrace the engineering reasoning and decision making processes. The investigation of the rationale behind these evolutions can be further benefit by allowing new designers to assimilate and digest the design process.
