摘要


現今人們對於健康保健越來越重視,且目前功能性鞋墊的使用者越來越多,對於快速客製化鞋墊之需求,現有技術都無法滿足,因此有開發新製程的必要。如何開發一種快速客製化鞋墊製程,使顧客可在最短的時間取得為其量身訂做的鞋墊,將會有市場的前景。 有別於目前傳統客製化鞋墊製造技術,本研究主旨分為『量測與鞋墊設計』與『製程設備與製造』兩部份,在量測與鞋墊設計方面,藉由量測足形以及足壓資料,來進行鞋墊設計,其足形資料用來建構鞋墊上表面曲面,希望將鞋墊上表面完全接觸足底,達到良好支撐效果,而足壓資料用來建構鞋墊底部特徵,調整鞋墊的軟硬度,可使壓力分散,而在製程設備與製造方面,以結合NC加工技術與真空熱壓成型技術為目的,整合三軸雕刻機與真空壓力平台作為製程設備,其製程步驟是利用NC技術加工石膏母模,再將熱塑性發泡材料加溫超過至熱變形溫度,至於石膏母模上抽真空使鞋墊材料完全貼合於母模上,等待其降溫至熱變形溫度以下,便可繼續NC加工鞋墊底面特徵,而完成客製化鞋墊。 本研究成果除了針對成品外形與CAD圖檔作大小比較,驗證其加工可行性與準確性,並分別以不放入鞋墊、放入無軟硬度調整孔鞋墊及放入完整客製化鞋墊的方式,量測出足底壓力行為,其結果顯示完全接觸足底的鞋墊上表面曲面,有效的分散其壓力分佈,而再加上軟硬度調整孔的結構,其效果更加明顯。

Come together with the awareness of health care, there are getting popular for people using functional insole in their shoes. It is necessary to develop a new manufacturing process to overcome conventional time consuming labor intensive process. There are two parts in this research, the measuring and design of the insole, and the manufacturing process for insole customization. Both plantar surface and the pressure of the foot have been measured in digital format. According to the measured data, an innovative insole structure can be constructed. The plantar surface will be the upper surface of the insole to provide the foot a good support. The mechanical structure on the bottom of the insole will be build based on the foot pleasure information to adjust the softness of the insole. The manufacturing process integrates the thermal forming process and CNC milling. The process starts from milling to the plaster block material to form the female part of the insole. The process followed by the thermal forming to make the invert EVA plate to be the male part of the insole. The CNC milling is then cut the back side of the insole to build up the designed structure to finish the manufacturing process. The resulting insoles show the ability to provide total contact between the foot and upper surface of the insole. This design can provide high pressure reduction over the foot. By adding the designed structure on the bottom of the insole, the pressure over the foot can spread further.
