Abstract. Product innovation is a process of knowledge and technology resource integration. This paper mainly researches the process and realization of product integrated innovation based on function. Several function integrated methods are presented, and the principle solutions are selected and evaluated based on extend effect model. The process model for product integrated innovation is proposed, which provides a systematic approach to product integrated innovation from functional design angle. A design example for integrated innovation of Chinese medicine demonstrates the proposed method is feasible.
The evolution of product function is the result of demand evolution or system evolution, which is governed by certain laws and is predictable. The composition of function structure and function classification are proposed to lay the foundation for function evolution. The stages division and laws of function evolution are proposed to point out the direction for function design, and the approaches of function are proposed to give the concrete method of function design. The forecasting zones of function evolution are proposed to provide a practicable space. The contradiction analysis is to make evaluation of function evolution, then TRIZ tools and CAI software can help designer to solve the contradiction and generate principle solutions. Integrated above contents, the product innovation process model based on function evolution and forecasting is proposed, which provides a systematic approach to product innovation from functional design angle. A innovative design example of pill dispersing machine demonstrates the proposed method is feasible.
Product configuration system, being a knowledge intensive system, plays an important role in order to realize Mass Customization. The Platformbased generic product configuration tool(PB-GPCT) being developed by Institute of Design for Innovation, Hebei University of Technology. PB-GPCT is a structure-based and domain independent configuration tool. For the realization of PB-GPCT, UML is chosen to construct the configuration model and OCL(Object Constraint Language) to express constraints. In order to manage the constraints of product easily, the approach of checking consistency of configuration model is presented. The theory of constraints hierarchies is introduced into the system of PB-GPCT in order to express customer requirements of different levels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
