Abstract This paper describes a method for evaluating the compatibility of a product design with respect to end-of-life product retirement issues, particularly recyclability. Designers can affect the ease of recycling in two major areas: 1) ease of disassembly, and 2) material selection for compatibility with recycling methods. The proposed method, called “clumping,” involves specification of the level of disassembly and the compatibility analysis of each remaining clump with the design’s post-life intent; i.e., reuse, remanufacturing, recycling, or disposal. The method uses qualitative knowledge to assign a normalized measure of compatibility to each clump. An empirical cost function maps the measure to an estimated cost to reprocess the product. The method is an integral part of our life-cycle design computer tool that effectively guides engineers to an environmentally responsible product design. A refrigerator in-door ice dispenser serves as an illustrative example.

Abstract This paper describes a methodology and tool which assist deployment of serviceability in the early stages of life-cycle design. Unlike design for assembly, producability, etc., design for serviceability (DFS) commonly occurs in the later stages of the design process. By this time, any design changes required to enhance serviceability are either costly or infeasible. We have developed a graphics-based computer tool to be used early in the design phase that employs the concept of service mode analysis (SMA), coupled with a service-based design description, to assess the impact of component relationships on life-cycle service costs. We also employ design compatibility analysis (DCA) to assess qualitative aspects of the design for serviceability concerns and provide the user with comments and suggestions for design improvements. Significant reductions in life-cycle costs and significant improvements in customer satisfaction can be achieved by including DFS in the design trade-off analysis process.

Increasing awareness of environmental burdens has led companies and designers to initiate design for the environment (DFE) programmes, which consider the design of products from the ‘cradle to grave’ and is also known as ‘life-cycle design’. In this paper, the use of a novel environmental performance technique to be used at the early stage of product design is presented. This technique, which is to be used as a framework for green product design, is demonstrated in this paper by evaluating the environmental performance between plastic and steel fuel tanks. The fuel tank comparison can be divided into five steps. In the first four steps, a modified house of quality (HOQ) is used to analyse the performance of fuel tanks in terms of requirements of environmentally conscious design. The final step is an overall assessment that synthesizes the results from the previous four analyses. As a result, the comprehensive environmental effects in the whole life cycle of fuel tanks are captured in the early stage of design.

Sustainable Product

Sustainable product design plans the entire life cycle of a product from its raw material selection, conceptual and structural formation, manufacturing processing, and usage to its end-of-life, reuse, and recycle. The product design needs the sustainable knowledge and proper tools. Current computer-aided design systems are insufficient to represent complex relationships of product functions, structures and life cycle options. It is required for design tools to support product life cycle planning with multi-objective optimal solutions. In this paper, our experience in design of a wheelchair is used as an example to discuss the need of design tools. The aim is to define ideal tools for design of sustainable products.

Geometric Feasibility

Minimizing the environmental load and cost throughout the product life cycle requires appropriate life cycle design as well as product design. In life cycle design, we must determine the life cycle scenario at an early stage and design the product to realize this scenario. Modularity is a key to linking life cycle scenario to an appropriate product architecture because modular architecture increases performance in life cycle processes, such as disassembly, recycling, maintenance, reuse, and upgrading, by unifying components applicable to the same lifecycle scenario. We propose a method for determining modular structure based on life cycle scenario by evaluating the similarity among lifecycle-related components attributes. We also evaluate the modular structure's geometric feasibility using an index indicates rigidity and compactness of the modules.

Material selection in mechanical products based on total life cycle design is a complicated work, which should be studied systematically. A material selection model of mechanical products based on total life cycle design was proposed. A set of candidate materials were screened out, and then assessed according to the technical, economic and environmental assessment index. The candidate materials were ranked by using by using Z-transformation method in each of the assessment index. Different weights were assigned to each of the three assessment indexes, and global assessment was carried out according to different strategies or requirements which pay more attention to technical, economic or environmental performance of the material product used. A case in selecting aircraft structure element material was studied. The analysis results showed that the method could rank the candidate materials and selected out the “optimized material”, and the influence of the subjectivity of designer was reduced. The method provides some practical values for preliminary material selection in the early design stage of the mechanical products based on life cycle design.
