碩士 === 國立勤益科技大學 === 工業工程與管理系 === 103 === Elderly Programme of the United Nations adopted in 1991 addressed the importance of concepts such as "independence", "participation", "care" , "self-realization" and "dignity." Based on the Declaration above, currently the world's countries have invested a lot of manpower and material resources to satisfy domestic needs of the elderly and care on daily life. Taiwan Republic of China as early as 1993 has already stepped into the "Highly Aging Society." According to the physiological characteristics of human beings by the medically proven researches, age recession begins mostly from his/her own feet parts. Among the aid facilities, walker is the mostly common one for seniors and those with reduced mobility. First, by helping users walking safely, the walkers increase autonomy mobility for life. Second, by preventing tendons of lower limbs from deterioration caused by stroke, the walkers improve the quality of life for elderly people or patients. In this thesis our research focuses on how to improve walkers by surveying the questionnaire feedback for user needs hen we employ methodologies such as PHA and 9Windows, to analyze indicators that contribute to meet user demands. Furthermore, by combining the 39 engineering parameters TRIZ innovation theory and the TRIZ contradiction matrix, we find 40 innovation principles for invention improvement, to improve the walker products comply with the principles of universal design concepts and be able to meet the demand. By using the foldable walkers with seat available in the market as the main body, we installed the wheels in each foot of walkers (2 bigger wheels at front end while 2 smaller wheels at the back end of walkers). Meanwhile, wheel brake has been equipped at the back end of walkers. By gently pushing the walker forward without oppressing the rear wheels, it creates momentum that helps user move forward safely. By oppressing the rear wheels to trigger the springs of brakes, it stops the users from moving forward. Conversely, releasing the brake makes walker continuously moving forward. Combined with the existing seat and folding function of walker available on the market, the function-improved walker is convenient to carry-out for longtime outdoor activities and makes it possible to combine recreation with rehabilitation for the users.
