Solution Overview
Problem
Conventional adhesive tape connection methods require high accuracy in alignment and limited flexibility in adhesive layer shape, restricting the degree of freedom in attaching members with multiple electrodes.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the adhesive tape is half-cut in the attaching step, then the adhesive layer can be attached to the member to be connected, but the degree of freedom in the shape of the adhesive layer is poor and alignment accuracy is required
Solution Approach 1:
The adhesive layer is divided into multiple independent segments by cutting lines extending from the separator surface to the adhesive layer surface. Each segment can be independently transferred to the member, allowing flexible shape configuration without requiring precise alignment of the entire adhesive layer. The segments are formed by cutting lines that partition the adhesive layer while maintaining continuity of the separator, enabling selective attachment patterns.
Solution Approach 2:
The cutting lines are formed in advance during the adhesive layer formation step, before the attachment process. This preliminary segmentation allows the adhesive segments to be prepared with predetermined shapes and positions, eliminating the need for high-precision alignment during the actual attachment step. The segments are ready for transfer without requiring real-time positioning adjustments.
2Adaptability or versatility
If cutting lines are formed in the adhesive layer at predetermined intervals, then segments can be selectively transferred with arbitrary patterns, but the process complexity increases
Solution Approach 1:
The separator serves as an intermediary structure that maintains the spatial relationship between cutting lines and adhesive segments. By extending cutting lines from the separator surface through the adhesive layer, the separator acts as a reference framework that simplifies the formation and transfer of adhesive segments. This intermediary structure enables arbitrary pattern selection without requiring complex positioning systems during transfer.
Solution Approach 2:
The patent replaces complex mechanical alignment systems with a simpler thermal transfer mechanism. Instead of using precision mechanical positioning devices to align adhesive layers with members, the invention uses heat and pressure to selectively transfer pre-cut adhesive segments. The heating and pressing tool activates the adhesive in specific segment areas, eliminating the need for complex mechanical alignment apparatus.
