本研究乃藉由人因工程學的探討與引用至可調式電腦桌之設計,以降低肢體健康方面之危害。對於桌面高度可調式電腦桌而言,可省去桌面下置物空間,免除調整高度時桌面下活動空間的不足,而桌面下活動空間宜用開放式空間,可減少桌面下活動空間不足所引起的健康危害。並基於成本與實用性的考量,可調式設計的電腦桌最佳調整範圍為600~800mm。 比較過市售之各種電腦桌後,得知其桌面大多固定而無法移動、無法旋轉及無法調整桌面高度,使電腦桌在使用上非常不靈活。因此,本研究應用電腦輔助設計來建立一張具有多自由度概念之電腦桌雛型,並透過有限元素分析軟體ANSYS Workbench,針對電腦桌之強度及剛性進行分析及設計,以確保電腦桌應有之強度及撓曲剛性符合要求。評估其結構的可行性後,設計並自行加工製造具有多自由度概念之電腦桌的原型,其桌面可以前後調整、左右調整、原地旋轉及高度升降調整,設計出創新的調整功能,並包含人因考量,帶給使用者新的操作電腦桌環境,機構多自由度調整功能是市售常見相關產品所沒有的功能,也是進入電腦桌市場的條件。
Most of the available computer tables on market have a fixed structure, which makes it unmovable, and couldn’t rotate or adjust height. All above that make the computer table inconvenient when in use. This research will design a computer table with multi-degree of freedom, which can freely rotate and move up and down. In this research, we will take cantilever mechanism as the computer table’s main structure, using finite element analysis software ANSYS Workbench to analyze and design the cantilever mechanism’s strength and rigidity, in order to ensure that the strength and deflection rigidity meet the requirement. The new computer table can not only use at home or in office, but also suit the injured patients, industry and commercial designer. Since the table’s height and position can easily adjust, it will gain the practicable and comfortable when in use.
