Abstract

This project deals with study of Boothroyd Dewhurst Design for Manufacturing and Assembly (DFMA) method in terms of design efficiency to design a low cost table fan. DFMA is a method for designing or redesign product. The advantage of DFMA is able to deliver a systematic procedure to analyzing a proposed design from the point of view of assembly and manufacture, improve the design efficiency, minimize the cost production and fulfill customers’ need. The total of part number table fan affecting the design efficiency of the product. To improve the design efficiency, the table fan is analyzed using DFMA method. The result of DFMA analysis is implemented in order to propose a new design of low cost table fan. The project was carried out through dismantle the unit of product, determined the function of each component by evaluating and compare the existing product using DFMA analysis. Lastly is implementing the DFMA analysis result and design guidelines to create a new design by generating a 3D modelling using CATIA V5R20 software. The selection criteria for a good design are based on number of part and operation time. DFMA analysis of optimized design is done and comparative analysis is made between the current and proposed design. The existing product design efficiency is 10.39% for National brand and 11.12% for Pensonic. Result shows that the design efficiency for proposed new design of table fan is obtained better percentage which is 16.61% rather than the existing design. . The final result shows that design efficiency for new design is increased by 5.49 to 6.22%. From the project findings, the number of parts is reduced to 15 parts and the operation time is 180.56s. Eventually, the improvement of table fan design that implemented from DFMA analysis result finally will be able to meet user requirements and satisfactions to design a low cost table fan
