Design Efficiency Analysis Towards Product Improvement for Eco-Friendly Using DFMA Method

Abstract

This paper presents the comparative study of design efficiency of two different brands of products, performing the same function using the Design for Manufacturing and Assembly (DFMA) method. The study aims to compare the products on the relative design efficiency. The DFMA method was used as it is a well-established technique for improving the efficiency of the product leading to minimizing production costs. It also shortens product development time by reducing the number of components in a product. The study used two different brands of dry iron as a case study. The result shows that the percentage of the design efficiency of dry iron A is 8.82%, whereas it is 10.34% of dry iron B. Thus, the dry iron B is much better as compared to A in term of its assembly operation and design efficiency. Therefore, the dry iron B is greener than dry iron A. Furthermore, a redesign of dry iron B was proposed and analyzed for the internal validation. The DFMA analysis result shows that the percentage of design efficiency of a new conceptual design of dry iron B increased to 18.08%. The application of the DFMA method to enhance the eco-friendliness of a product has been proven to be highly useful in design work.

Integrated product development and lifecycle management in building production – A case study for logistic of mortar distribution in building sites

“…Both principles follow a logical pattern; because the DfM is the predecessor of the DfA [ 18 ]. Therefore, the two principles can be combined to create a new one: Design for Manufacture and Assembly (DfMA) [ 19 ], which covers the two design principles simultaneously, i.e., the product development team must consider the manufacturability and assemblability of a product, during the entire designing process. Thus, the DfMA aims at designing easy-to-manufacture multifunctional components and reducing the use of fastening components and unnecessary adjustments [ 13 , [18] , [19] , [20] , [21] ], whereas PLM deals with lifecycle management.…”

Evaluation of Design Efficiency Using Boothroyd Dewhurst Method for PCB Drilling Machine Products

“…There are six main design structures as shown in Figure 1. Referring to [10], the morphologic matrix framework is utilized to arrange all conceivable plan arrangements, for every item work, characterized at the practical displaying stage. Figure beneath demonstrates the morphological framework found for this item.…”
