Research On The Design Of Home Lifting Aids Based On UCD

As the aging of our country’s population continues to deepen,the number of disabled elderly people continues to increase.Most of these people lose or partly lose their ability to take care of themselves,have varying degrees of mobility impairment,and need to complete their daily displacements with the help of assistive devices and caregivers.At present,the development of the assistive device industry in China is relatively slow,the lack of refined division of lifting assistive devices,the single function of the product,and the poor user experience have caused the disabled elderly to be unable to use assistive devices to complete daily shifts,which has increased the workload of caregivers.Taking the above factors into consideration,this topic aims at the home displacement problem of the moderately disabled elderly,and considers the needs of caregivers,and designs a home displacement product.On the basis of ensuring safe displacement and good maneuverability,the product adds new functions such as bed assisted displacement,seat conversion and fall prevention,which improves the efficiency of home life displacement of disabled elderly people and the care experience of caregivers.Through literature research,the subject clarified the relevant concepts of UCD,the current research status at home and abroad and the design process,combined with this subject to summarize the product design process,and run it through the subsequent design practice.The subject investigates users,existing products and the use environment,and initially determines the target users,product types and basic functional elements of the subject.The topic uses questionnaire surveys and user interviews to investigate related users,and establishes a user conceptual model through user portraits and user experience journey maps to clarify user needs.Based on the above research,survey results and UCD theory,the product design principles of this topic are summarized to guide design practice.In the design practice,the target user was further defined,the product shifting operation process was sorted out,and the specific function of the product was determined.A large number of targeted sketches were drawn according to the preliminary design positioning;two types of product design schemes were sorted out according to the determined functions and design principles,and they were compared and analyzed through the method of user satisfaction testing to obtain the best design scheme.In the deepening of the product design plan,ergonomics is used to standardize the product size,and combined with the existing technology,the product function,movement mechanism,structure,control method,material and product color are analyzed in detail,and the three-dimensional model and use scene are used to construct And showed the final product design plan.In the research of the product design of this subject,in accordance with the summary of the design process and principles,and fully considering the needs of target users,product safety,ease of use and user experience,the design practice has been completed,providing reference for the design of related assistive products.To promote the coordinated development of my country’s assistive devices and the elderly care industry.
