The Design And Research Of The Safety Seats Of The Car Based On The Principles Of Kansei Engineering

The car, as an indispensable means of transport, has also been owned by growing people especially with the constant deepening economic construction and the continuous improvement of living standards of China; however, with rising car ownership rate, injuries for children due to traffic accident follows which are gaining greater and greater concern by the society. According to relevant statistics, there are over 18,500 each year for children fewer than 14 died in traffic accidents. The mortality rate is 2.5 times of that in Europe, and 2.6 times for the case of the United States which made the traffic accidents come the first cause of death among children under the age of 14.One of the important reason of that high rate of injures and death for the child under 14 in traffic accident is that the current car's safety equipment and emergency measures are designed in accordance to adult body size which is not suitable for children's physical specifications, and therefore can not effectively protect the lives of child occupant. Experiments show that the use of child-only safety car seats can reduce a large extent on the rate of child occupant injury, which made using child car safety seats come into a necessary.The safety car seat is a kind of ancillary equipments which is installed on the car seat for infants, young children or adolescents to protect the personal safety. In China, the laws and regulations of child occupant have not been fully established yet; apart form that many parents lack of the knowledge or have misinterpretation of the safety of child occupant. Therefore, the child-only safety car seat covers a very low penetration rate in China, which resulted in the design of the child-only safety car seat keeps a huge gap from its counterpart like United States and Europe.The research is based on the basic principles of Kansei Engineering. Under the guidance of perceptual psychology of consumers and for applicable people, the design of the child-only safety car seat makes the starting point by first gaining of theories and research of design aesthetics, ergonomics, child pathology, consumer psychology and product semantics and questionnaires as the second step, then comprehensive analysis of the survey data. Finally, the industry finds the best pattern of the device which is more suitable for young children to explore Physical and psychological demandsThis paper analyzes both the status and the problem of injures happened in traffic accident of child by integrating the research status of situation and the problems of the case at home and abroad. Then both the main content and significance of research of the industry would be established in this paper. After that the paper would give out a brief introduction of the history of child-only safety car, the development process and basic classification of this industry; then come to the summary of both the characteristics of infantile form and structure of child-only safety car seat in accordance of the above-mentioned information. Then this paper describes the basic concepts, domestic and international development, procedures and methods of Kansei Engineering, Finally, the paper applies method of qualitative type of inference layer by layer from Kansei engineering to guide the design of child-only safety car seat by step with theme of "love and care", which aims on starting from the theories of the following four aspects: the security, integrity of form, the principles of modern aesthetics and functionality to explore a scheme of feasible design of child-only safety car seat with improved product structure, color, texture and other factor in order to analysis.
