Function Integrated Product Innovation Based on Laws of Need Evolution

Abstract

Function integration is an effective method for product innovation to enhance the product competitiveness in the market. Laws of need evolution can predict potential needs of products. In order to improve the innovative design, this paper proposes a function integrated product innovation method based on laws of need evolution. Firstly, laws of need evolution and strengths-weaknesses-opportunities-threats analysis (SWOT) are used to determine needs of the target product. Products with the function similarity are searched from the patent database. Functions of the similar products are then integrated to meet of the target product. The preliminary solution is obtained by using Theory of Inventive Problems Solving (TRIZ) tools. The innovative solution is formed according to the design priority of the product. Thus, a function integrated product model is constructed based on laws of need evolution for innovative design. Feasibility and rationality of the proposed method are verified by the innovative design of a cleaning device of the oil sump in a range hood.
