Design evaluation plays a considerably important role in product development process, and evaluation helps to provide reference for plan improvement or optimization. With the integrative development of different disciplines and improvement of relevant theories, ways to design evaluation methods become diversified, changing from subjective qualitative evaluation to objective quantitative evaluation. From the perspective of industrial design, the typical evaluation methods involved in product design and development process were combed and summarized here, providing reference for further research and bearing certain significance for the construction of systematic product evaluation system and optimization of product design and development process.
Abstract. since large engineering equipment cannot meet customers' personalized demands or respond fast to market changes, the method to conduct innovative design of engineering equipment based on modular strategy is proposed here. With the innovative design of excavator for example and by combining the product characteristics of excavator, the modular design study was carried out and the modular design process worked out to utilize modular design method for excavator. By combining different function modules, effects with various functions can be achieved, providing an entry point for the sustainable development design of engineering machinery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
