Research On Comfort Design Of Rehabilitation Wheelchair Based On The Characteristics Of Elderly People

Due to illness,trauma or degenerative factors,many of the elderly have to use wheelchairs to move. Long-term ride in an ordinary wheelchair and lack of physical activity,often lead to further deterioration of the condition of these elderly,and may even lead to the complete loss of walking ability.In addition,the existing wheelchair in the market is mostly uncomfortable and less functional,and few of the wheelchairs are specifically designed for older people.To deal with these problems,this paper makes a study on the comfort design of rehabilitation wheelchair based on the characteristics of the elderly.The main work of this study is as follows:(1)Analysis and research the current status?the development trend and key technology of rehabilitation medical industry?rehabilitation robot and recreational wheelchair;and find out the shortcomings of the design of rehabilitation wheelchair;(2)To determine the needs of the elderly rehabilitation wheelchair: using literature research,questionnaires,interviews,functional design methods and Kansei engineering methods to study the elderly human characteristics,mining the functional design requirements and morphological preferences of the rehabilitation wheelchair in the elderly;determine the style of rehabilitation wheelchair and clear the design direction;(3)Summed up the design principles of rehabilitation wheelchairs for the elderly: safety,comfort,ease of use,lightweight and aesthetics;(4)Complete the design of the elderly rehabilitation wheelchair:under the guidance of the comfort design method and ergonomics,the elderly rehabilitation wheelchair's size?shape?structure ?function and materials are designed;(5) Carry out the man-machine engineering analysis of the rehabilitation wheelchair: using SAMMIE to analysis the man-machine matching degree,static force and reachable domain,andverify the comfort and reliability of recreational wheelchairs.Rehabilitation wheelchair can help elderly people who has difficulty in walking with the rehabilitation training of lower limbs at home,maintain the flexibility of lower limb joints,prevent muscle atrophy,so that the elderly can enjoy a healthy and happy old age. Therefore,it is of great practical significance to study the wheelchair which is comfortable and capable of exercising on the leg in line with the characteristics of the elderly.
