Abstract

Design for Assembly method is an established framework that is used to create a product. By implement DFA method in this project the design analysis is conducted for Cornell CFF-12P fan. The important aspects that need to be considered is assembly process, handling difficulties & insertion difficulties. The problem with this fan is a lot of fastener use to assemble the product. The objectives of this project is to reduce part while maintaining the function of fan, to analyse the comparison between the design efficiency original design and improved design and to provide optimised solution that better than existing fan in market based on DFA guidelines. Based on study, it is proven that the assembly time is save from 52.31 s to 15.8 s. the DFA index also show improvement from 0.6 to 6.3. The advantages of using DFA method has been proved in redesign the Cornell CFF-12P fan. The design efficiency that has been calculated manually also show increasing from 29% to 76%.
