Research And Design Of Lower Extremity Disabled Personalized Travel Tool

Chinese government pointed out that China has entered the aging society gradually in 2014,Population aged over 60 reached 210 million,accounting for 15.5% of the total population.Nearly 40 million of them are disabled and half disabled.It is predicted that the elderly population will reach 400 million in 2035,and the number of the disabled and semi disabled elderly will increase further.How to make disabled and semi disabled elderly enjoy better quality of their live is a social problem that must be solved.According to the second national sample survey on disability in April 2006,huge number of people with disabilities in China who need the help of transport tools.The importance of mobility tools for lower extremity disabled people is obvious.China is moving towards a well-off society in an all-round way,the people’s economic level has improved,and the level of science and technology has been changing with each passing day.All kinds of new technologies have penetrated into every aspect of our lives.In the new situation,how to integrate the economic progress and scientific and technological progress into the means of transportation,bring the vital benefits to the disabled people,is an urgent task for the designers.This paper extensively analyzes the existing technology and related design at home and abroad,and investigates and studies the physiological characteristics and psychological characteristics of users.The paper analyzes the specific scene of the work,and sorts out the different terrain and the requirements of passing tools.With the modular design meet the different user personalization options,the vehicle is divided into mobile seat module,module and interface module for specific research and design.The mobile module according to the economic capacity and use of the scene design of the "professional indoor" and "outdoor" two modules are analyzed and a detailed demonstration of each module according to the users’ demand;the design of "universal" and "comfortable type" and "special demand type appearance.Finally,the requirements of interactive modules are briefly explained.The innovation of this design is that different situations need to be dealt with by different modules,and these modules are integrated into a system.Lower limb disability can be combined with their own needs,their own wishes in different occasions,with different module combination to achieve his own satisfaction.
