Performance Evaluation System Of Elderly Transfer Products Under Collaborative Operation Scenario

In recent years,due to the increasing aging situation,the number of disabled elderly people has continued to increase.As a tool to assist disabled elderly people in position transfer and movement,the elderly transfer products can effectively improve the elderly’s transfer experience and reduce nursing operation burden.However,the current design of elderly transfer products often considers more about how to meet the experience and needs of elderly users,while ignoring the operating experience of nursing staff.Blindly improving the experience of elderly users will increase the operating load of the nursing staff and make the shifting process more difficult,causing the nursing staff to reduce the overall operation quality due to physical fatigue and psychological incompatibility.Therefore,it is of great significance to coordinate user needs for different operation scenarios and improve the overall operation quality of collaborative operation objects in a relatively balanced manner.This thesis first defines and classifies operating users,operating behaviors,and transfer products,and conducts theoretical research on synergy,operating behavior analysis methods,and operating quality evaluation methods.Secondly,the elderly and nursing staff are analyzed physiologically and psychologically,and the operating scenarios and operating behaviors of the transfer products are classified and analyzed through behavioral observation combined with kinetic analysis.On the basis of user and operation research,based on the inclusive design concept and operation behavior evaluation method,the quality evaluation indicators of elderly users and nursing staff operating the shifter were summarized.According to user characteristic analysis,operation scenario and behavior analysis,and operation quality evaluation index,the user operation synergy effect in different operation scenarios is analyzed,and a coupling coordination degree model based on synergy is constructed,and the data is analyzed through Likert 5-level scale.Evaluation and quantification,on the basis of quantification,calculate the coupling coordination degree,judge the pros and cons of a series of operation behaviors performed by users in different operation scenarios according to the calculation results,and assign weights to users.Then,on the basis of research and interviews with different users,summarize the use problems and needs of the transfer products in different scenarios,apply the AHP/QFD/TRIZ integrated design method,use the AHP method to quantify the needs of elderly shifter users,and combine different operating scenarios Calculate the comprehensive weight by assigning weights to users under the following conditions,and obtain the focus and ranking of user needs for the elderly shifter under collaborative operation,use QFD method to convert user needs into technical requirements and analyze their importance,use TRIZ to eliminate conflicts in design strategies,and The JACK simulation analysis is carried out for the indicators with strong human-machine relationship,and the design strategy is further optimized.Finally,combined theoretical research,user and scene research,and design strategy for elderly transfer product design practice,and verified the feasibility and effectiveness of the research results.
