摘要

本研究旨在研發一種站立式輪椅，其主要目的是針對一般傳統式站立式輪椅，在穩定性上作突破性的改善，且整合站立與高坐姿之兩項功能，並提供低製作成本、結構簡單和準確的動作之站立式輪椅，作為站立式輪椅使用者之另一種新選擇。
本研究利用機構合成之方法，首先先確立設計需求與設計限制，並經過一般化、特殊化的過程，篩選出適合本研究所需之輪椅站立與高坐姿機構之特殊化鏈，並將其轉換為特殊化圖集，最後並還原成機械裝置，此外，本研究藉由Pro/Engineer Wildfire 2.0電腦輔助設計軟體，進行輪椅站立與高坐姿機構之尺寸合成，建立其3D Model，並應用Pro/Assembly模組中Mechanism指令之模擬功能，對所設計之站立式輪椅進行動態模擬，確認輪椅於站立與高坐姿動作過程中無干涉情形發生，再利用藉由COSMOSDesignSTAR 4.5進行應力、應變及位移之分析，以確定所設計輪椅之強度，最後則進行實體模型之製作，使本研究設計之站立式輪椅得到驗證，本研究經過以上種種步驟所完成之站立式輪椅具有製作成本低、結構簡單和準確的動作，適用於脊椎損傷癱瘓或下肢癱瘓者使用之站立式輪椅。

In this thesis, a low cost, simply-constructed, and precise in movement stand-up wheelchair was developed by integrating the 2 major functions of the traditional stand-up wheelchair, allowing users to move from a seated-to-standing position and sitting on a higher position. At the same time, some breakthrough improvements on stability have been made as well. This newly developed Stand-up wheelchair may be a brand new choice for wheelchair users.
First of all, this thesis adopts mechanism synthesis to establish its design concept under the consideration of its design constraints. Through the processes of generalization and specialization, the specialized kinematics chain is sorted out as the best for the demand of stand-up and sitting of the wheelchair. It is then transferred as the atlas of specialized chains, and finally returns to a mechanical device. In addition, the computer aid program, Pro/Engineer Wildfire 2.0, proceeds with dimensional synthesis to build up the 3D model; while the Mechanism instruction of Pro/Assembly is applied to simulate the movements of subject wheelchair in order to ensure no interferes are involved or occurred. Furthermore, COSMOSDesignSTAR 4.5 is used to analyze stress, stain, and displacement, so as to confirm the strength of the wheelchair. Last but not least, the physical mock-up of the wheelchair is made to testify this new design of stand-up wheelchair.
With completion of all the processes mentioned above, this new stand-up wheelchair acquires qualities of low cost, simply-constructed, and precise in movement. It is a stand-up wheelchair suitable for spinal cord injured (SCI) and paraplegic users.
