Using Axiomatic Design and TRIZ in (re)Designing of Product Architecture Toward Upgradable Products

Abstract

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.

An Integration Matrix for Investigating the Impact of Design Changes in Mechatronic Products

“…The effectiveness of many applications was analyzed, revealing our work's reasonable application in practice. The reverse zigzagging approach adapted from [1] was used in the analysis of the existing design stage to break down the current design of a mechatronic product and to reflect the technique of a descending order for the product structure and design hierarchy to the lowest level by applying AD (in the case of an AGV). The findings revealed three layers of multidisciplinary relationships between DPs and FRs at their fundamental level (mechanical, electrical, and information technology).…”

“…Compared with two previous studies [1,22], in terms of modeling efficiency, the modeling approach suggested in this study to analyze the information data in an original design provides a number of advantages. Due to the interconnections of the analyzed components, it is comparatively less difficult.…”

“…Furthermore, Janthong [1] presented reverse zigzagging as an approach allowing a novice designer to examine and grasp the design rationale of an existing product. This method was developed by breaking down the product structure and design hierarchy to the lowest level of DP and FR linkages, as shown in Figure 10.…”

“…A design change may be initiated for many reasons, such as to improve a design, to support customers' needs, to innovative technology development, to respond to legal and regulatory policy changes, and the pressure of competitiveness. In addition, the terms of the business process should provide new products and support after-sale and maintenance services, which include repairing, retrofitting, and renewing/renovating, in order to extend the lifetime of a product, because products become obsolete over time [1]. These are seen as challenges for the engineering designer, who must manage these changes as much as possible, including customer needs, product specifications, functioning, and the component aspects of an assembly.…”
