Current market environment are volatile and unpredictable ; the competition has intensified and market windows have shortened ; the ability for design products to meet customer’s requirements has become critical to success. Cutting time-to-market, reducing costs and increasing quality are widely accepted as key factors to successful product development. To compete, many manufacturers across all industries have increasingly incorporated electronics (microelectronics, power electronic, measurement, sensors and actuator technology) and software (routing, plannification, artificial intelligence, and embedded software) into their mechanical products in order to deliver features and services that customers want at a competitive price. However, most manufacturers lack expertise for multi-disciplines integration including software, electronics and mechanical engineering leading to poor products and services. The key element to develop such product is identifying functional requirement and knowledge utilization based on a scientific approach to provide the suitable solution for both designing new products or redesigning existing products with respect to customer’s needs. This research presents a method to design (redesign) mechatronics products by combining the axiomatic design and case-based reasoning approaches. The methodology explains how design axioms are used for the analysis of the existing product functionalities compared with the new functional requirements and then adapting to the design purpose. The case based reasoning is used as a general framework for the reuse of design purpose and applied when a similar function is required. A case study of a redesigned electric vehicle as automated vehicle is provided to illustrate an application of the method. Innovation has increased the new product value, which has not only improved the product efficiency but also extended the product life cycle and the need for new engineered design method.
