The Research Of Product Design Based On Natural Tendency

People's habits and lifestyles are tendencies which have developed for a long time and are difficult to change. These tendencies have great significance to the study of product design. In line with human natural tendency, the products and their users will play their maximize efficiency, reduce the unsafe acts and improve the working and living efficiency. At a deeper sense, the further study of the human natural tendency can help us effectively control and predict men's behavior, and make people act in accordance with the unique needs of human actions, which can promote the society and human beings' development.But due to the impact of external factors and their own conditions, human beings' natural tendencies tend to be diversity, and because of these differences and diversity, we have various difficulties in the study of the natural tendency. Up to now, the repeatedly mistakes show that we are still in a formative stage in the study of the natural tendency. When mistakes happen, people may mainly analysis reasons of products, machines or tools, rather than the human factor as a major part of the study. These neglects on the natural tendency of human behavior will not solve the root causes of errors, for these reasons, the author did the research and analysis of the human natural tendency from the perspective of the product design.Firstly this article analysis the internal and external factors to the impact of natural human tendency, that is, people's act tendencies are formed in the domination of the acts demands over a long period of evolution and adaptation, which is the direct products of the interactions between humans' evolution and objective environment. Then on these basements, the article conducts people's sense characteristics, the operating characteristics of acts, behavioral needs, awareness, irrational behavior etc. as basis of the study, and explores the basic laws of conduct and behavior habits from a macro point of view, as well as rational behavior tendencies or irrational behavior tendencies in the performance of the products, and so on. In these basement, creating a number of design principles for guiding product design, in which can adapt to people's natural tendency to the highest degree and reduce some unsafe behavior and unnecessary mistakes, so people can work and live comfortably, relaxed and happily, which to promote the society and human beings' development.
