Abstract

Modular design can shorten the product development cycle and enhance the product research and development capability of enterprises. To better solve the problem of module interface coupling after module partition, the present modular product design method has been improved based on the theory of inventive problem solving and axiomatic design theory. This article summarizes the engineering parameters commonly used in modular design based on the requirement analysis and conflict problems of modular structure design. And in the process of dividing the functional modules by fuzzy clustering algorithm, we propose defining and classifying the principle (technical) correlation between parts by these parameters. Then the coupling relation of each module interface is analyzed by the design matrix of axiomatic design and the conflict solving tool of the theory of inventive problem solving is utilized for decoupling. Finally, the high chair is taken as the design object and the design process is used to verify the feasibility of this method.

Highlights

Modular design is an important method to shorten the product development cycle, enhance company competitiveness, and make the product easy to disassemble, repair, and recycle, thereby reducing the waste of resources
The TRIZ theory can effectively solve the problem of ‘‘how to do.’’ Besides, according to the requirements of modular design, we summarized the engineering parameters commonly used in modular design and use it to define the principle correlation of parts in the fuzzy clustering algorithm stage
The modular innovation design process integrated with TRIZ and axiomatic design (AD) proposed in this article is divided into functional decomposition of product, module partition by fuzzy clustering algorithm and fuzzy evaluation method, establishment of module design matrix, and decoupling with TRIZ tools

Summary

Introduction

Modular design is an important method to shorten the product development cycle, enhance company competitiveness, and make the product easy to disassemble, repair, and recycle, thereby reducing the waste of resources. Aiming at the unreasonable interface structure and other problems after module partition, the AD can help designers to identify the problem, but still lacks specific problemsolving tools.[22] the TRIZ theory can effectively solve the problem of ‘‘how to do.’’ Besides, according to the requirements of modular design, we summarized the engineering parameters commonly used in modular design and use it to define the principle (technical) correlation of parts in the fuzzy clustering algorithm stage. The modular innovation design process integrated with TRIZ and AD proposed in this article is divided into functional decomposition of product, module partition by fuzzy clustering algorithm and fuzzy evaluation method, establishment of module design matrix, and decoupling with TRIZ tools.
