Product concept design method combining living system theory and fbs

Abstract

The invention discloses a product conceptual design method combining a life system theory and an FBS. The method includes the steps of first expressing FBS design elements based on the life system theory, and utilizing a key subsystem of the life system theory to perform standardized expression on product functions, behaviors and structures of products; reconstructing a conventional FBS model, andreconstructing an FBS design process on the basis of FBS design element expression based on the life system theory. As a result, the local deformation and local innovation design problem which cannotbe solved by a conventional FBS design process is solved, and the design quality is improved by adding check operations. According to the method, by using the life system theory to perform design element expression on an FBS model and reconstruct the design process, an operable LST-FBS model is formed. The product conceptual design method has feasibility and reliability on the basis of versatility and comprehensiveness, and can simultaneously support variant design and innovative design and form a standardized and designable design process.

Description

technical field [0001] The invention relates to a concept design method, in particular to a product concept design method combining life system theory and FBS. Background technique [0002] Conceptual design is in the early stage of product design and is very important in the design process. Research shows that 70% of the cost of the product life cycle is determined in the conceptual design stage. At the same time, conceptual design has the least constraints on designers and has a large space for innovation. It can best reflect the experience, wisdom and creativity of designers, and is considered the most critical in the design process. most creative stage. FBS (Function-Behavior-Structure) design model has been widely used in the conceptual design field, such as innovative design, variant design. The FBS model transforms a series of designed functional requirements into design descriptions through behavior and structure, conforms to design thinking habits, is easy to impl...
