Investigation And Research Of Primary And Middle School Students Desks’ Usage

According to the human engineering principle as the basic, through domestic and international design, statistics, basic design theory, elementary and middle schools in Shaoyang city general classroom desks and chairs the use status of the investigation, combined with the primary and secondary school students to conduct human data measurement and carry on to the student questionnaire, then:First、Based on the domestic and abroad research situation and development trend of the research, understanding of domestic and foreign furniture design present situation, summarized the development trend of design, combined with the existing advantages and disadvantages, thus better for their design services.Second、Combining students furniture concept, through the Hunan province Shaoyang City37middle and Primary School of the desks and chairs in procurement status, use present situation investigation and analysis, in view of the students’ psychological characteristics and needs, to the national standard " school desks and chairs function size " as research guidelines for existing products, the functional size measurement, validation of primary and secondary school desks and chairs the main ergonomic problems.Third、According to the national standard GB/T5703-1999" basic human body measurements for technological design project", through2012in Shaoyang city7-15year old urban and rural students in939anthropometric data analysis and research, the data obtained through statistics and calculation, combined with the human scale percentile and the human body static size selection, determine the desks and chairs models and function size standard.Fourth、Based on the principle of ergonomics, human anatomy of the human body problem, put forward the desks and chairs the tall, wide, deep, base seat backrest angle, desktop high, under the table space and other design parameters of basic principles. Discussed make sitting people comfortable material selection and color on the use of a psychological impact on in-depth summary.Fifths With adjustable for the design of the basic point, combined with human body measurement data analysis, tables and chairs, desks and chairs of the materials and structures, based on ergonomics, Then using the objective optimization method, finally arrive at the optimum scheme.The discusses and the research of this paper provides some new train of thought of how to develop and use the primary and middle school’s desks and chairs,make the desks and users can be very good fit with each other providing a better eviroment for the primary and middle school students, improving the quality of studing, and providing a reference for the future development of adjusting desks’ design.
