Functional Behaviors Synthesis and Innovation for Mechanical Systems

doi:10.3901/JME.2019.19.128

Abstract

Abstract: Incompetence in generating innovative functional principles has restricted the capability for AI-based functional synthesis approaches to obtain novel and innovative conceptual design schemes. In consideration of the behavior characteristics of mechanical systems, with a set of behavior segments to express the kinematic behaviors of common complex mechanical systems, a new kind of functional synthesis approach in accordance with the equivalence relations in granularity, quotient structures and quotient attributes based on the domain synthetic theory in quotient space is presented. Different equivalence partition rules lead to produce different function configuration schemes, in which the subfunctions are formed and contributed by all of basic operation actions in the divided subsets. For making the synthetic subfunctions formed and contributed by all of basic operation actions in the divided subsets take place in time and space continuously and orderly, the partition schemes relative to the granularity equivalence relations are secondly divided into two quotient spaces corresponding to the time sequence equivalence relation and the space position equivalence relation, respectively. Then the intersection quotient space of these two quotient spaces is synthesized, in which all of basic operation actions in the synthetic subfunctions occur in time and space continuously and orderly. In this way, the functional synthesis process can not only generate novel functional principles and new functional schemes, but also guarantee the generated subfunctions take place in time and space orderly and sequently. These kinds of functional schemes will benefit of finding optimal structures to realize the overall function.

Key words: functional innovation, synthesis in quotient space, equivalence partition, CAD-based conceptual design, mechanical system
