A Hybrid Model for Acquisition and Evaluation of Product Innovation Solutions

Abstract

The fusion of Quality Function Deployment (QFD) and Theory of the Solution of Inventive Problems (TRIZ) can identify customer requirements for product design to effective search the design solution. Existing studies of QFD and TRIZ are mainly based on experience of designers to extract the product characteristics for customer requirements. A single evaluation indicator is used in the solution evaluation. This paper proposes a scenario-based evolution method to map customer requirements and technical characteristics. The defective technical characteristics is identified in the design evolution process. Design conflicts of technical characteristics are solved using tools in TRIZ. A mixed information evaluation method is used for selection of the final solution. A hybrid model is developed for acquisition and evaluation of product innovation solutions. The innovative design of a car satellite antenna verifies the proposed method.
