中文摘要 | 公路自行車專用的下垂式把手,除了供騎乘者操作施力外,也可藉由改變握持的位置,達到減緩手部不適的程度。因此,本研究以探討下垂式把手握持部位之舒適度為主要目的。首先,針對市面上現行銷售106件產品,以型態分析法歸納產品的屬性元素表,進行圓管式把手中心線路徑的舒適度實驗,以了解中心線路徑對握持舒適性的影響;接續以主觀性問卷評量資料蒐集方法,進行握持部位與舒適度之關係實驗,探討把手對於手掌的接觸面與受身體重量傾斜壓迫的疼痛狀況。根據實驗數據以迴歸統計的二次函數曲線檢定,推估出最舒適的把手面寬尺寸,以該尺寸重新設計新式樣的把手造形,利用CAD搭配快速成型技術(RP-Rapid Prototyping)完成新式樣把手的製作,最後,再進行新式樣把手的握持舒適度實驗與問卷評估。結果發現,新式樣把手在上握位置寬度為53.8mm與側握位置寬度為40.2mm時,可得到最佳的手掌接觸面積,同時,也可使得疼痛區域減少。除此之外,以把手上方靠近把手中心的橫桿部份,經由兩相關樣本的符號檢定方法,比較新式樣把手與舊把手的優劣狀況,結果顯示新式樣把手接觸面積大於舊式把手,且呈現顯著差異性。並依實驗數據進行綜合評估,發現新式樣把手確實優於其他把手,且增加騎乘握持的舒適度。 |
英文摘要 | The downward handle of road bikes not only could transfer the hand grip force of the rider, but also improve the hand stress by changing the grip location. Therefore, this study discussed the comfort of the hand grip position of downward handle. It first conducted morphological analysis on the product attribute elements, and conducted comfort experiment on the handle curve path, in order to confirm the effect of curve path on the grip comfort. It also conducted subjective questionnaire survey to measure the data, and experiments on the force impact area and comfort, in order to discuss the contact surface and received pressure of the handle in relation to the palm. Based on the result of the analysis of the experiment, we would be able to estimate the most appropriate handlebar size by using regression statistics quadratic function, and a new design handlebar can be created with Rapid Prototyping technology. The final experiment is executed to evaluate the comfort sensation on the new RP handlebar. The results showed that the new RP handlebar can obtain the optima contact area in the width of 5.38mm at up position and 4.02mm width at lateral side, but also eased the pain region. In addition, the pressured contact area of the redesigned handlebar is larger than the old ones, and has significant difference by using sign test method. According to the experiment data, the redesigned road bicycle handlebar is indeed better than the others, and increase holding comfortable sensation. |
