Product requirement-structure mapping method based on effect

Abstract

The invention discloses a product requirement-structure mapping method based on an effect. According to the method, it is thought that all stages of concept design must be comprehensively considered, and an efficient and consistent design process is provided for concept design of a product. Thus, the product requirement-structure mapping method based on the effect is put forward. Common steps mainly include the steps that requirements are analyzed, the requirements are converted into functions, and the functions are mapped into structures. By means of the method, design efficiency can be improved, and design cost is reduced.

Description

technical field [0001] The invention belongs to the field of conceptual design of mechanical product design, and in particular relates to an effect-based product requirement-to-structure mapping method. Background technique [0002] In the entire design and manufacturing process of a product, although conceptual design only accounts for 5% of the development cost, it often determines 70% to 80% of the total cost and directly affects the quality, cost and performance of the product. Therefore, it is necessary to develop efficient product concept design methods to reduce design costs and ensure design quality. The mapping of product requirements to structure is an important content and key process of product conceptual design, which is mainly embodied by effect-based requirements acquisition, processing, transformation technology, and function-to-structure mapping algorithm. The purpose is to quickly establish a set of conceptual structures through the mapping method. Existin...
