| Summary: | 碩士 === 國立臺北科技大學 === 工業設計系創新設計碩士班 === 105 === Due to the booming economy, growing living standards and the progress of medical and hygiene technology, the lifespan of human beings is significantly extended. However, more and more elderly people face deterioration physically and psychologically. For example, the function of hands is deteriorated by ages. The happening rate of deteriorative arthritis is 20-30% at 50 years old, but rises to 70% at above 70 years old. Therefore this kind of arthritis is also known as elderly arthritis.
By means of literature review, observation method and user testing to find out problems about wrining out water of towels for older adults. Three designs, “Twist It”, “One Piece” and “Double Wring”, were proposed to be tested by three groups of older adults respectively. As a result, we found that age isn’t an only factor that affect the grip strengh of older adults. The physiological conditions of users is the most important factor. In this study, comparing to “Twist It” and “One Piece”, “Double Wring” can help testee wring out more water at about 50%. Meanwhile, hand-injured testee use “Double Wring” that can wring out more amount of water than those without hand-injured. Therefore, we conclude that “Double Wring” might help hand-injured people wring out the towels efficiently.
