Abstract
In a general design process, development of criteria and brainstorming of ideas must be have applied before generating design concept. Then, the selection of best design concept will be conducted. Nevertheless, in real market situations, the contribution of failure product marketed increase due to deficiency in design selection process. Thus, the research is aimed to develop a new framework for design selection at the conceptual design stage using the Theory of Inventive Problem Solving (TRIZ) and Analytic Network Process (ANP). The TRIZ method is intended to regulate its limitation by integrating simultaneously with the ANP technique. The ANP consists of two dependence feedback; outer dependence and inner dependence which to measure the accuracy of the result. The TRIZ identifies specific problem and ANP set a goal for a research project. The system parameter will be identified and implement into the contradiction matrices. The inventive problem solving is then generate and develop ideas to be assessed through ANP judgement using Super Decision™ software. The simultaneous integration contributes in solving the contradict problem and selecting the best design concept at the early stage of a design process. This integration is verified by a case study of a manual wheelchair as it assists designers in selecting the most optimum design concept. A case study has been conducted at Rehabilitation Department, Serdang Hospital with assistance from 3 expertise in wheelchair manual handling and technique. Different types of injuries may need different types of manual wheelchair. The discussion includes the main criteria needed in a manual wheelchair, main issues of a manual wheelchair, the process of using a manual wheelchair and et cetera. Therefore, the case study of a manual wheelchair is applied into the simultaneous integration method and generates 4 design concepts of a manual wheelchair. The validation of the selected design concept is described in term of sensitivity analysis, which is to generate the highest value among 4 design concept of a manual wheelchair. The sensitivity analysis was performed respect to each design concept and respect to each criteria. Therefore, Design concept 3 is selected as the best design concept due to its higher value in the normal weight.
