Research and implementation of product functional design based on effect

Abstract

Functional design is a process includes function understanding, function recognition, function representation, function modeling and function-to-structure mapping. The effect in TRIZ is extended by multi-pole effect model and effect chain modes, and then the functions and flows in TRIZ are reclassified. The combinative relationships among functions are discussed, and the function modeling based on effect is proposed. The principle structure is introduced, and the combined rules are presented. The functional design process model for function modeling and function-to-structure mapping is proposed, and the computer-aided functional design software is developed. A design example is presented to demonstrate the proposed functional design methodology. © 2007 International Federation for Information Processing.
