摺疊課桌椅之設計與分析

本研究針對多功能摺疊課桌椅，首先蒐集相關文獻、學術期刊、論文、各國專利公報、網站資料及產品型錄後。再針對各種功能的椅子，依其使用功能，將椅子依據椅子功能、收折功能，和桌子功能區分為三種使用功能，再依此三種功能將其分類為單功能用椅、雙功能用椅，和多功能用椅，並針對其優缺點進行探討，作為本研究之參考依據。經由文獻之分類與分析後，了解各類型坐椅之優缺點。接著依據椅子、桌子和收摺型態的不同，分別定義不同的需求。在坐椅部份需考慮人體工學之設計，桌子部分則需符合一般桌面使用高度，而收摺方面更需考慮收摺平整和攜帶方便。本研究利用機構合成的概念設計，並利用電腦輔助繪圖軟體SolidWorks製作摺疊課桌椅之電腦模型。最後藉由各種不同軟體，來分析或檢驗本研究設計之摺疊課桌椅，包括干涉檢查、作動模擬和應力分析。干涉檢查主要確定本研究設計之摺疊課桌椅，在椅子型態、收摺型態，和桌子型態下無干涉的現象。作動模擬是要確定本研究設計之摺疊課桌椅能夠符合概念設計。應力分析則是要確定本研究設計之摺疊課桌椅能夠承受一定的重力，而不導致損壞。

This research is aimed at multi-functional folding chair. First of all, This research collect the relevant document such as academic periodical, thesis, patent communiqués, and catalog of products. By these documents, This research divide the chairs into three kinds of function of use. They are chair function, foldable function, and desk function. By these three functions, we can classify these chairs into single function, double of function, and multi-functional chair. Then we treat and study the advantages and defects of these chairs. By analyzing and classifying these documents, This research can understand the advantages and the defects of the chairs. According to the different types of chair, desk, and folding type, This research can define different kinds of demand. In the part of seat, this research have to consider that the designs of ergonomics. And need the desk which is designed with the adaptable height. Then this research still have to consider that the chair can be folded up and carried very convenient. By the concept of mechanism synthesizing,this research use the computer software of the SolidWorks to make the computer model of the foldable chair. Finally, this research analyze and examine the folding desk chair designed in this research by different software. They are including the check of interfere, move simulation and stress analysis. By these analyses, we can confirm that the chair is convenient and safe to use and the design accords with our concept.
