Abstract

This report describes about the implementation of redesign the manual wheelchair by using the application of concurrent engineering. The scope based on the existing wheelchair design and the appropriate application of Concurrent Engineering (CE) tools. The method used for gaining the data was from the survey done by distributing of questionnaires to several numbers of people and the wheelchair user. From the data achieved, it can be classified into several categories to be studied. Data will be analyzed by using the Quality Function Deployment (QFD) method to verify the highest rank from the people and customer requirements. The new proposed design of wheelchair was drawn using SolidWorks software based on the QFD result achieved. In the same time, both design and redesign of manual wheelchair were analyzed by using the Design for Assembly (DF A) tools which is TeamSET software, to compare the design efficiency to achieve the objectives of the project. Result shown that the design efficiency for redesign manual wheelchair obtained better percentage rather than the existing design. From the study, even the redesign possesses a greater number of part compared to the existing design, it still has the advantages based on the convenience functions and the percentage of design efficiency. Eventually, the improvement of wheelchair design finally will be able to meet user requirements and satisfactions.
