Research On The Design Of Mobile Assistant Products With Limited Light And Moderate Activities

The development of elderly products has always been valued by people.A good old-age product can not only realize its basic functions and help the elderly's life,but also improve the psychological effects of the elderly.For example,to sooth mood and strong fitness.Among the assistive devices,according to the national standard "Auxiliary Appliances-Classification and Terminology"(GB/T 16432-2013)is equivalent to the 2011 version of ISO9999(Assistive Product for Person with Disability-Classification and Terminology),the 794 kinds of assistive devices are divided into 12 main categories,130 sub-categories and 781 sub-categories.Among them,personal mobile assistive device is one of 12 main categories,including 16sub-categories and 103 sub-categories.This article mainly through a comprehensive understanding of the physical condition of the elderly,to assess the elderly's balance ability,lower limb weight bearing capacity,gait pace,upper limb control ability,cognitive ability,self-care ability,living environment and other factors,research design can help the elderly complete the movement of the body consisting of a series of large limb movements such as sitting up,standing,picking up.In this paper,according to Holden's walking function level,the classification of behavioral disorders in the elderly was targeted to the elderly population with limited light and moderate activities,that is,the elderly population without natural disasters,diseases and natural aging.Firstly,based on the analysis of the human body shape,joint mobility,muscle strength,muscle tension and activities of daily living,the influence of the elderly on the movement of the body is studied.For the main damaged parts,research on the existing mobile auxiliary products on the market,through the analysis of competitive products,comparison of advantages and disadvantages of similar products,existing product analysis at home and abroad,and literature research methods,find out for mobile The breakthrough point of auxiliary products.Break the inherent limitations of existing products,explore their connotations and give them new forms.Among them,the author through the comparative study of the different categories of existing mobile aids,and finally chose to use the unpowered exoskeleton for the elderly as the main research carrier of this topic.2.In the experiment,the leg of the experimenter was kept at an inclination angle of 12°,and the outline of the leg of the experimenter was collected by gypsum cloth,and the plaster was poured.Product analysis was performed on the experimenter's leg plaster model to make a small batch prototype.Third,verify whether the various parameters of the product are reasonable,make physical objects,and carry out subsequent design practices.Finally,in the design practice,the author comprehensively considers the structural form of the product and the application of the new material,and studies and analyzes the unpowered exoskeleton,and summarizes its basic principles,the authorhas carried out a lot of thinking,and finally designed a mobile auxiliary product for the elderly.
