Product Innovation Design Process Model Based on Knowledge Service

Abstract

With the advent of the era of knowledge economy, knowledge plays an increasingly important role in product innovation design. In order to help designers to acquire and apply knowledge in product innovation design process, a kind of model of product innovation design process based on knowledge service was proposed. Product innovation design was divided into several stages: requirement analysis, problem determination, problem solving and solution evaluating. And the mapping relationship between design process, service strategy and service knowledge was also analysed. Taking the designers as the main body of knowledge service, a knowledge service strategy supporting design process was proposed. In view of the different knowledge services required in different stages of product innovation design process, the forms and service strategies of knowledge in various stages of product design were studied step by step, and the product innovation design service composition model that conforms to the designer's habits of mind was put forward. This method links the knowledge and design process in each stage of product innovation design process with the combination of innovation strategy and design knowledge, which is used to assist designers in tracking and applying the required knowledge resources for innovation design. Finally, a prototype system of product innovation design knowledge service was developed, and a design case of micro force measuring device was presented to demonstrate the practicability and validity of the proposed method.
