Design Development of a Coffee Maker using Design for Assembly Method

Abstract

The purpose of this research is to evaluate the design of a coffee maker by using Boothroyd Dewhurst Method which this method is one of the Design for Assembly (DFA) methods. DFA method will help to simplify the assembly designs of the product that will leads to significant cost savings and less tine to produce a product. Main objective of DFA is to estimate the difficulty of assembly, eliminate unnecessary parts and assembly tooling and design products that are less costly to manufacture. The study will focus on analyzing the current design of coffee maker, reducing the number of parts, comparing the design efficiency and the cost between the current and improved design. The product is evaluated by using Manual Handling Table and Manual Insertion Table. The results of current design are used to make improvement to the coffee maker. Then, new design is made by eliminating or combining the old design so that total cost and time for assemble the coffe maker is reduced. Lastly, comparison is made between new and old design.
