目的：本研究針對市售負重式雪橇車，以3D建模的方式建立改良版的模型，期待改良後的3D雪橇車模型，能更加符合使用者需求。3D模型是問卷訪談重要的素材，透過問卷訪談相關領域專家，並歸納出最終器材改良的方向。方法：本研究透過問卷調查的方式，藉由“市售負重式雪橇車改良設計調查問卷”訪談17位，以及“雪橇車手把改良設計調查問卷”訪談13位相關領域專家。在問卷調查前，先以3D建模的方式建立改良後的雪橇車圖型，透過改變置放重量的方式以及更多功能的握把設計，期望相關領域的專家能夠在問卷訪談中，透過觀看3D模型去給出對於設計上的見解與看法。問卷的訪談除了填答問卷中的題目外，會同時透過錄音方式記錄受訪之領域專家的口頭補充說明，以獲得專家對於不同設計版本的雪橇車最完整的看法與建議。蒐集完問卷的資料以及錄音的檔案後，統整問卷的內容，並討論訪談中逐字稿內容。結果：經過兩階段的問卷訪談後，第一份問卷的17位受訪者，在比較了三款雪橇車後，47%認為改良第二款最好；35.2%認為改良第一款最好；17.6%認為現有市售版最好。第二份問卷的13位受訪者，在比較了三款握把後，53.8%最喜歡改良第一款握把；38.4%最喜歡改良第二款握把；7.6%最喜歡現行市售版握把。 結論：本研究經過詳細的調查和設計過程，完成了實際的外觀設計。受訪者提供了豐富的回饋與建議。儘管目前距離實際製作出實體機台尚有一段距離，但是對於未來負重式雪橇車的改良方案，已經有了非常具體的方向。負重模式改以斜掛槓片的方式，能讓使用者更方便放置取用，類似槓片架的外觀也帶給使用者熟悉感並提升使用器材的意願。許多受訪者認為，不一定只能有一種握把選擇，雪橇車的握把原本就能拔起來換邊，握把便可當作不同的套件，讓使用者依據自己的需求和喜好，選擇自己想使用的握把。在本研究中，握把新增有橫桿的設計，能提供能讓使用者的手腕、手臂甚至肩膀以不同的角度訓練，並且更貼切日常生活中推拉物品的習慣，是多數受訪者重視的特點。

Purpose: This study aims to explore commercialized weighted sleds, using 3D modeling to create improved versions that better meet user needs. The 3D models serve as essential materials for the questionnaire interviews with experts in related fields, helping to identify the final direction for equipment improvements. Methods: This study using questionnaire to survey. Two surveys were conducted: the "Survey on the Improved Design of Commercialized Weighted Sleds", and the "Survey on the Improved Design of Sled Handles" involved interviews experts in related fields. 3D modeling was used to create images of the improved sleds. During the interviews, in addition to completing the questionnaire items, the experts' verbal supplementary explanations were recorded. After collecting the questionnaire data and audio recordings, the content was consolidated and analyzed. Descriptive statistics were used to organize the collected data, which was then further analyzed and discussed. Results: After two stages of questionnaire interviews, the first survey of 17 respondents concluded that, after comparing three sled designs, 47% preferred the second improved version, 35.2% favored the first improved version, and 17.6% preferred the existing commercial version. The second survey of 13 respondents concluded that, after comparing three handle designs, 53.8% preferred the first improved handle, 38.4% favored the second improved handle, and 7.6% preferred the current commercial handle.
