Research Of The Design Of The Desks And Chairs In Primary Schoolbased On The Body Engineering

In recent years, much attention has been paid to children’s health problems, with the general rise of people’s reasonable change of dietary structure and nutrition consciousness, the development of children has changed obviously compared to a decade ago, but the health status of primary school decline year by year, the burden of studies have influences on children’s physical and mental health. pupils spend a quarter of a dayin theregular classroom of the elementary school.children easily bow-backed after using low desks and chairs for a long time.It is possible for students to be shortsighted if The table is too high, the chair is too low and the distance between eyes and the book too close or too far.Incorrect learning posture affects bone development of students. the problem of the mismatch of the desks and chairs and pupil height in regular classroom of elementary school has been increasingly prominent, so it is very necessary and significant to study and design the desks and chairs in regular classroom of elementary school. As the important facility of students learning, student desks and chairs design should change according to the development trend of dynamic. This paper will have human body engineering study desks and chairsof primary school classroom by using the knowledge of human body engineering, surveying, the knowledge of the anatomy, psychology and other disciplines.the method of observation, analysis, induction method, questionnaire survey, field testing and methods of market investigation.First of all, this topic analyze the characteristics of the population who apply the classroom, with the combination study the size of pupils, cognitive features and psychological characteristics,and points out serious consequences produced by the dis-matching of school desks and chairs,which provides theoretical basis for development and improvement of the elementary school desks and chairs design.Secondly, understanding our country’s current teaching model, analyzing the influence of the teaching mode of primary school classroom desks and limitations, and summarize the using condition by combining with questionnaire survey method and field testing,comparing and analyzingthe size of desks and chairs in primary school classroom, proposing the problems of the elementary school classroom combined with the market present situation and the human body engineering.Finally, study and design desks and chairsin the primary school classroom by using the human body engineering, and combining with anthropometry, anatomy, psychology and other disciplines of knowledge, which is reasonable applied to the design of primary school classroom desks and chairs,putting forward the design principle and concept design of fixed partition tables and chairs, which makes the the selection of students’ desks and chairs more diversified so as to improve the satisfaction of elementary school students use, and fully meets the students’ physiological and psychological needs when using classroom desks and chairs.
