MODULAR PRODUCT DESIGN : A LIFE-CYCLE VIEW

摘要

This paper discusses the incorporation of modularization into mechanical designs. The researchrnuses a definition of modularity that incorporates the potential of modularity based not only onrnthe form/function structure of a product but also life-cycle processes such as manufacture,rnassembly, service, and recycling.rnModularization, due to the functional independence it creates, has been called the goal ofrngood design. Industry has made an effort to modularize products to be flexible to the needs ofrnend users. In addition, some modules are created with some aspects of assembly in mind. Lifecyclernmodularity entails maintaining independence between components and all life-cyclernprocesses in different modules, encouraging similarity in all components and processes in arnmodule, and maintaining interchangeability between modules.rnIn this paper, the definition of product modularity is given. A measure of relative modularityrnand a modular design methodology are developed that encourage modularity, prevent a cascadernof product design changes due to changes in life-cycle processes, and support agile reaction tornchanges in life-cycle processes. A short example is used to clarify the work.
