Research On The Design Of Household Medical Care Shifter Based On Ergonomics

The service object of the design is immutable,that is people.In the optimization of product systems closely related to life,such as medical and nursing products,we should fully meet the diversified needs of "people".Household medical transposers have been studied for several years in developed countries,but there is still a broad space for growth in the market of our country.This paper studies the design of household medical shifter for patients with lower limb dysfunction.The specific research contents are as follows:First of all,by consulting the data,this paper summarizes the research status of household health care products at home and abroad,and defines the overall research framework,contents and methods through the analysis of the data.Secondly,on the basis of the current situation of product research,the design elements are analyzed,and the corresponding relationship between the guiding significance of different design elements to product design and user requirements is formed,and the hierarchical model and judgment matrix are determined.Through the analysis of the judgment matrix,it is demonstrated that the extracted design elements can not only meet the subjective judgment,but also accord with the objective evaluation.Thirdly,under the guidance of ergonomics theory,the human factors involved are analyzed,and the functional structure of the shifter is designed through human body size measurement and human function analysis.DC motor drive as the main driving mode,relying on hydraulic push rod and linkage mechanism to further clarify the overall structure design of the shifter.Fourth,through the Kano model analysis method,the user demand survey questionnaire is designed to demonstrate the rationality of the functional concept of the shifter and whether it can really meet the needs of users.Under the support of the results of the reliability and validity of the questionnaire,modeling and evaluation are carried out to demonstrate whether it meets the requirements of ergonomics.At the end of the article,the market of household health care products in China is prospected.
