Design For Assembly: An approach to increase Design Efficiency of Electronics Home Appliance

Abstract

Innovations lead market. In today's computational and technocrat world, product development needs a prompt respond to accomplish market demands in short time and must be economically sustainable. Since the product design strongly affects the assembly process, it must be taken care at the initial stage which results in improving manufacturing process, saving assembly time and thereby cost. In this paper, an active approach to reduce the number of parts and thereby increasing design efficiency has been taken into consideration. Design for assembly (DFA) approach was applied to facilitate product structure without losing its standardization and functionality of product. Comparative analysis between, current and proposed design of refrigerator components like evaporator fan in freezing compartment and door hinge assembly are described out of the many sub assembly part reduction in total number of parts of refrigerator. Using DFA guidelines, we reduced total number of parts from 328 to 172, thereby leading to increase in design efficiency by more than 25%. The results obtained from the analysis leads to achieve our required expectations and can be further applied in manufacturing industries in order to improve the design efficiency.

Redesign of an In-Market Conveyor System for Manufacturing Cost Reduction and Design Efficiency Using DFMA Methodology

“…Design efficiency for the product development is calculated based on the theoretical number of parts, time taken to assemble the parts and total part count of the component. The calculations are shown below [4]:…”

Generic Challenges and Automation Solutions in Manufacturing SMEs

“…Consequently, they are in better position to adapt quickly to customers' demands and offer customized products, the challenge however is their productivity and level of automation especially in high salary countries in Europe. Globalization, market changes and not least digitalization technologies challenge manufacturing businesses to think in smart innovative solutions [1] [2]. A range of manufacturing development initiatives are available in industrialized economies such as Industrie 4.0 in Germany, Advanced Manufacturing Partnership in the United States and Manufacturing Innovation 3.0 in the Republic of Korea [3].…”
