Constraint Based Design from Research into the Classroom

by David Serrano, Univ of Puerto Rico,

Abstract: Design is constraint oriented; much of the design process involves the recognition, formulation and satisfaction of constraints. Constraints are continually being added, deleted and modified throughout the development of a new device. Of particular interest are the constraints that relate the design's performance, governing physical laws and its geometrical properties. This paper presents a brief historical overview on constraint based design systems, the fundamentals of the technology, ongoing research on constraint-based systems for design and manufacture at the University of Puerto Rico and the author's experience with a commercial constraint-based system in the classroom. Sample mechanical design problems solved by the students are also presented.
