塑性流動接合製程係為在接合件上產生局部塑性變形，使其材料流入被接合件之接合區中，兩者彼此扣合之製程。然而，目前關於塑性流動接合的文獻常見於板材與板材間之接合，而少有扣件與板材塑性流動接合之探討。本文以上界限法預測接合時所需之接合力，及透過有限元素分析軟體建構出FEM模型，獲得抗拉力與抗扭力。接著進行自固接合螺帽之專利分析，使用TRIZ系統化創新方法得到專利迴避之建議，再根據其建議做創意發想，得到性能優於原產品之自固接合螺帽的創新設計。

Clinch joining is a process that the material is forced to flow into the joining area joined together with the other part by local plastic deformation. Over the past years, several studies have been made on one sheet clinch joined with the other one but no study has been made for the clinch joining process between the sheet and the clinch nut. In this thesis, an upper bond method has been used for predicting the staking force when clinch joining and a finite element simulation model has been constructed to evaluate the push-out force and unsupported torsional resistance by FEM commercial software. Then the patents concerned with the clinch nut have been analyzed and the suggestions have been obtained through TRIZ systematic innovation methodology to avoid the existed patent claims. Based on these concepts, innovative thinking has been made and the novel design of the clinch nut has been obtained which has better performance than that of the original one.
