目前對於因意外傷害或中風等因素所造成的單側殘障者，尚無適當的輪椅供其選擇，仍處於寸步難行的困境。故具內變速器之單側驅動輪椅的設計，在於滿足偏癱患者的需求，以提供驅動省力、操控簡易的行動輔具，並改善其生活的舒適性和自主性。本研究是從產品的開發與工程設計的程序進行模組化設計，首先根據單側驅動輪椅的市場分析與文獻探討，並訂定設計規範。再者，將單側驅動輪椅分為驅動系統和轉向系統進行設計，其中以內變速器的設計最為關鍵，選擇五桿行星齒輪式內變速機構，以具有直接檔、低速檔、空檔、倒檔等四種檔位為設計需求，根據輪椅內變速器設計方法與程序，依序設計和發展其構造合成、檔位合成、運動合成、以及性能評估。最後，選擇一個最佳的可行設計，進行調速機構的設計與配置來作循序的檔位切換控制，以提供單側驅動輪椅可以自如地前進或倒退的行進和轉向。
本研究成功地設計出一個符合僅能以單側肢體活動的輪椅使用者生活需求的單側驅動輪椅。是以單手來操控轉向操作桿，以單腳踩踏曲桿來驅動輪椅。不但操控直接、位移明確、轉向角度大，且驅動舒適省力，長時間操作亦不會造成運動傷害。再者，其內變速器的運用更提高了機械效率。本研究成果可作為其日後製造的依據，以造福如半邊癱瘓之單側驅動輪椅使用者。

At present, it is difficult for one-sided disable patients who suffered an accident or hemiplegia to find a suitable mobile instrument. The design purpose of this one-sided driven wheelchair with a transmission hub is an effort-saving and easily driven wheelchair. It can not only meet the needs of such patients but also enable them to have a comfortable and independent life. The modulized design in this study is based on the procedures of product development and engineering design. First, the design requirements were set according to literature and market analyses on wheelchairs with one-side drive. Then, the design was processed in two parts, the driving system and the steering system. Among these, the design of the transmission hub is the most important part. A transmission hub with 5-link planetary gear was chosen for this design. Based on the design requirements of a four shift-levels (i.e direct, low-speed, neutral and reverse gear shifts), structural synthesis, shift-level synthesis, kinematics synthesis were developed according to the design method of transmission hubs for wheelchair. Besides, performance tests were also conducted. Finally, the most practicable design was chosen to develop a shift-level control governor so that the wheelchair can freely move forward, backward and change its directions.
In this study, we have successfully designed a one-side driven wheelchair which can meet the specific needs of one-side disable patients. The steering of the wheelchair is operated by one hand and the driving treadle is propelled by one leg. The operation is direct; the movement is clear; the steering angle is large; and the driving is effort-saving. Even long time driving won’t cause secondary injuries. Moreover, the utility of a transmission hub has largely enhanced the mechanical efficiency of this wheelchair. The results of study can serve as basis for production so that one-side disable patients can be greatly benefited
