Recovery Potential

Application of axiomatic design (AD) for the purpose of enhancing end-of-life recovery potential of a product has been the main focus of this paper. To demonstrate the usage of AD in this particular area, a case study that involves keypad assemblies of mobile phones is presented. The functional requirements (FR) of the two assemblies were defined differently (only Handset 2 involves refurbishment-related FRs). Using evaluation approach presented by Kwak and Kim (2010), it can be observed that when recovery-related requirements are omitted, application of AD produces a keypad assembly that fulfills the FRs derived from customer needs with more complicated product architecture. In contrast, when recovery-related FRs are included during problem definition using axiomatic approach, the disassemblability of the resulted keypad is improved and thus increasing recovery potential in the event of replacing defective keypad, while satisfying product-related FRs.

Product modularization aims to improve the overall design, manufacturing, operational, and post-retirement characteristics of products by designing or redesigning the product architectures. A successful modular product can assist the reconfiguration of products, while reducing the lead-time of design and manufacturing and improving the ability for upgrading, maintenance, customization and recycling. This paper presents a new modular design method called the House Of Modular Enhancement (HOME) for product redesign. Information from various aspects of the product design, including functional requirements, product architecture and life cycle requirements, is incorporated in the method to help ensure that a modularized product would achieve the objectives. The HOME method has been implemented in a software system. A case study will be presented to illustrate the HOME method and the software.

Analysis And Design

Recently, much attention has been focused on the design of the fuel assemblies in the Pressurized Light Water Reactor (PLWR). The spacer grid is one of the main structural components in a fuel assembly. It supports fuel rods, guides cooling water, and maintains geometry from the external impact loads. In this research, a new shape of the spacer grid is designed by the axiomatic approach. The Independence Axiom is utilized for the design. For the conceptual design, functional requirements (FRs) are defined and corresponding design parameters (DPs) are found to satisfy FRs in sequence. Overall configuration and shapes are determined in this process. Detailed design is carried out based on the result of the axiomatic design. For the detailed design, the system performances are evaluated by using linear and nonlinear finite element analysis. The dimensions are determined by optimization. Some commercial codes are utilized for the analysis and design.

Environmental Criteria

Legal and public pressures have urged companies and firms to practice good environmental policy. Apart from that, growing environmental consciousness among consumers has also evolved into a potential marketing opportunity that many companies deem valuable. In order to effectively manage a companys environmental policy, linking it closely to purchasing activities can potentially be a helpful way. In this paper, fuzzy axiomatic design (AD) approach is used to address the issue of green supplier selection. A case study is presented to demonstrate the utilization of fuzzy AD principles in analyzing qualitative environmental performances of suppliers with the consideration of all sub-criteria. The proposed approach is able to produce indicative results in terms of information content and is capable of identifying the most eligible supplier among three alternatives. This signifies that the application of fuzzy AD approach in the area of green supplier selection is feasible and is worth further exploration.

This paper aims to provide an insight to later researchers on the application of axiomatic design in the area of design for end-of-life (EOL) management. Among all life cycle stages of a product, design and development stage is the one that influences the later stages the most in terms of environmental impacts. In order to achieve sustainable product development, one of the considerations to be taken during the design stage is EOL management. EOL management process can be enhanced by utilizing a robust design method as well as an effective method for evaluating product design. Recent researches show that application of axiomatic design in the field of eco-design (especially design for EOL management) is still in a premature stage despite having a vast application area that covers the aspect of product design, manufacturing and supply chain management. Nonetheless, a case study published recently on eco-design using axiomatic approach has shown adequate feasibility and effectiveness. Therefore, design for sustainable EOL using axiomatic approach is worth further exploration.

Design is done in many fields. Although the design practices in different fields appear to be distinct from each other, all fields use a common thought process and design principles. Consequently, the true differences between these fields are minor, often consisting of the definitions of words, the specific data, and knowledge. In comparison, larger differences can exist within a given field between simple systems and large systems due to the size and the time dependent nature of functional requirements. The axiomatic approach to design provides a general theoretical framework for all these design fields, including mechanical design. The key concepts of axiomatic design are: the existence of domains, the characteristic vectors within the domains that can be decomposed into hierarchies through zigzagging between the domains, and the design axioms (i.e., the Independence Axiom and the Information Axiom). Based on the two design axioms, corollaries and theorems can be stated or derived for simple systems, large systems, and organizations. These theorems and corollaries can be used as design rules or guidelines for designers. The basic concepts are illustrated using simple mechanical design examples. When design is viewed axiomatically, not only product design but all other designs, including design of process, systems, software, organizations, and materials, are amenable to systematic treatment.

The movements to personalized products and up-to-date technology speed up the time of products become obsolete (partially obsolete) before the end of their life. Thus, the capability to design product more flexible is the key competitive factor leads to secure product cost and extend the product life time. In this paper, the (re)design methodology that leans on Axiomatic design and TRIZ has been developed and implemented to enhance flexibility of a product meeting customer’s requirements and support future change. The paper shows, through a case study, how the flexible are created for specific industrial product: electric towing vehicle.

The United States generates more than 250 million tons of municipal solid waste (trash/garbage), with only 34% being recycled. In the broader global environment, the problem of waste management is becoming increasingly relevant, demanding innovative solutions. Traditional End-of-Life (EOL) approaches to managing waste include recycle, reuse, remanufacture and disposal. Recently, resynthesis was proposed as an alternative to traditional EOL options that combines multiple products to create a new product distinct from its parent assemblies. Resynthesis employs data mining and natural language processing algorithms to quantify assembly/subassembly combinations suitable for new product combinations. However, existing resynthesis methodologies proposed in the design community have been limited to exploring subassembly combinations, failing to explore potential combinations on a materials level. The authors of this paper propose a material resynthesis methodology that combines the materials of multiple EOL products using conventional manufacturing processes that generate candidate resynthesized materials that satisfy the needs of existing domains/applications. Appropriate applications for a resynthesized material are discovered by comparing the properties of the new material to the functional requirements of application classes which are found using clustering and latent semantic analysis. In the course of this paper, the authors present a case study that demonstrates the feasibility of the proposed material resynthesis methodology in the construction materials domain.
