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.

Environmentally Conscious Design

This paper describes the outline of “life cycle design” course the author teaches and illustrates some experiences and findings with results of questionnaires to attendees of the lecture. “Life cycle design” is a half-year course to third-year students at Tokyo Metropolitan University, Japan. The main subject is environmentally conscious design focusing on life cycle thinking. This course intends to establish general and correct viewpoints toward relationship between manufacturing industry and the environmental issues, which are indispensable knowledge as mechanical engineers, rather than to educate environmental specialists. Results of questionnaires indicate that this course succeeded in increasing students’ interest in this area and awareness of importance of the environmental issues. However, some students feel bewildered because of wide variety of topics and, therefore, lack of a central theory.

The Relationship

Environmentally conscious design is focused on reducing the environmental impact of engineered systems, but common practice in life cycle analysis overlooks the relationship between a product’s usage-context and its environmental performance. Existing studies rarely consider operational variability or the correlation between performance, design, and usage variables. Probabilistic graphical models (PGMs) provide the capability of not only evaluating uncertainty and variability of product use, but also correlating the results with the product’s features and usage context. This discussion explores the use of PGMs as a tool for evaluating operational variability in products and including the results in life cycle inventories. The tool is illustrated for environmentally conscious product design through an example study of an electric kettle.

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.

General Method

A reverse engineering methodology is presented for identifying environmentally conscious design guidelines for use in the conceptual stages of product design. Environmentally conscious principles and guidelines help designers improve environmental impacts of products by making better decisions during conceptual design stages when data for life cycle analysis (LCA) are sometimes scarce. The difficulty in using the current knowledge base of guidelines is that it is not exhaustive and conflicts are not well understood. In response, the authors propose a general method for expanding the current set of guidelines and for understanding potential environmental tradeoffs. The method helps designers extract environmentally conscious design guidelines from a set of functionally related products by combining reverse engineering with LCA. The guidelines and LCA results can then be used to inform subsequent design cycles without repeating the process. Although in environmentally conscious design, reverse engineering is commonly applied to studies of disassembly and recyclability, the methodology and case study herein show how reverse engineering can be applied to the utilization stage of a product’s life cycle as well. The method is applied to an example of electric kettles to demonstrate its utility for uncovering new design guidelines.

Abstract The growing emphasis on environmentally conscious design and manufacturing approaches has placed new burdens on designers. The amount of information available to designers is of great significance in making life cycle assessments on a product. However, well-established commercial CAD systems do not provide means for evaluating most of the different life cycle aspects of the product being modeled. Hence there is a need to have a CAD-environment where the life cycle tools (DFX tools in this work) are integrated with these systems so that life cycle design is made possible. In the research discussed in this paper, the specific focus is to enable the quantification and enhancement of product assemblability, serviceability, recyclability, remanufacturability, de-manufacturability, and life cycle impact during product design. Guidelines for integrating some of the commercially available CAD packages (I-DEAS and Pro/ENGINEER) to these assessment models, and ways to use the input information to some these assessments for making other assessments are developed. A case study is given to illustrate the approach.

Environmentally Conscious Design

Abstract This paper approaches environmentally conscious design by further developing a reliability model that facilitates design for reuse. Many reliability models are not suitable for describing systems that undergo repairs performed during remanufacture and maintenance because the models do not allow the possibility of system reconfiguration. In this paper, expressions of reliability indices of a model that allows system reconfiguration are developed to enable life-cycle cost estimation for repairable systems. These reliability indices of a population of repairable systems are proven theoretically to reach steady state. The expressions of these indices at steady state are obtained to gain insight into the model behavior, and to facilitate life-cycle cost estimation.

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.
