全球鞋類產業多採品牌與製造分工模式，亦即以歐美國家為主之品牌商負責產品設計、市場行銷與通路管理，以台商佔多數之亞洲地區「原始設備製造商」則僅負責產品生產製造。因此，「原始設備製造商」其主要價值即為迅速依循品牌商設計概念於約定時間內交付符合約定品質標準之成品。品牌商其所最為在乎之鞋品品質，在於避免發生成品鞋無法發揮基本行走功能之客訴事件，例如鞋面與鞋底因貼合不佳而致脫落。倘發生此類嚴重品質問題，除造成品牌商之商譽受損外，負責生產製造之製造商亦恐面臨來自於客戶之鉅額索賠。
本研究提出基於「萃智理論」之思維與工具，針對鞋類產品製造中之鞋面與鞋底貼合品質問題進行系統性觀察研究與改善。「萃智理論」此項系統工具可協助產業由過往僅依靠資深從業人員工作經驗以推斷與解決品質問題之窠臼，轉換為使用具清楚流程之系統工具以解決問題，俾令組織人才養成與寶貴經驗得以延續，進而避免發生因人員更替而致組織內解決問題能力之降低。
本研究首先以特性要因分析法分析問題可能潛在原因，其後將改善各要因之提案及所遭遇矛盾轉譯為39項工程參數後，再行代入矛盾矩陣中，最終搭配相對應之40項發明原理發想出創新改善方案。經七週拉應力試驗結果顯示，鞋面與鞋底貼合拉應力之變異係數由第一週之36.68%逐步降至第七週之17.36%，顯示品質穩定度逐步提升並達成改善目標。

Global footwear industry adopts a model of division of labor between branding and manufacturing. Brand owners‚ mainly from U.S. and European countries‚ are responsible for product design‚ marketing and channel management‚ while the Original Equipment Manufacturers (OEMs) mainly from Taiwan and Asia‚ are responsible for product development and mass production. Therefore‚ OEMs‚ the prime value of is to quickly convert customer design concepts into actual samples‚ and then deliver finished products that meet the agreed quality standards at the agreed time. The quality focus that brand customers care about most is to prevent the finished shoes from being unable to function for basic walking. Functional situations‚ such as shoe uppers and soles detaching due to poor fit. If this serious problem occurs‚ it will not only cause damage to the goodwill of European and American brands‚ but also damage the Taiwanese business representatives responsible for production. The factory faces huge claims from customer.
This study proposes to use the thinking and tools of TRIZ theory to systematically observe‚ study and improve the fit of uppers and soles in the manufacturing of footwear products. This systematic tool of TRIZ theory allows the industry to no longer rely on senior practitioners to use past work experience to infer the cause of the problem and then solve it‚ and switch to using system tools with clear processes to guide problem solvingso that the company's talent development and valuable experience can be continued‚ and avoid problems within the organization due to personnel replacement. Reduction in problem strength〪
This study first conducts root-cause analysis using the fish bone analysis, then translates the proposals for improving each root cause and the contradictions encountered into 39 engineering parameters and then put them into the contradiction matrix. Finally, it is combined with the corresponding 40 invention principles, coming up with innovative improvement solutions. After seven weeks of experiments, the research results show that the Coefficient of Variance of tensile strength test was reduced from 36.68% to 17.36%.
