Solution Overview
Problem
Existing methods for adhering an insulating sheet to a metal member in power storage modules face challenges due to the risk of foreign matter attachment and difficulty in precise positioning, especially when using double-sided tapes.
Innovation Solution
A thermosetting insulating sheet is thermocompression-bonded to the surface of a metal member, using a structural adhesive agent, to facilitate adhesion and prevent foreign matter attachment, while allowing for precise positioning and enhanced insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a double-sided tape is used to adhere the insulating sheet to the metal member, then the insulating sheet can be fixed to the metal member, but foreign matter may be attached to the adhered portion and positioning precision is difficult to ensure
Solution Approach 1:
The patent changes the adhesion method from mechanical bonding (double-sided tape) to thermal bonding (thermocompression bonding). By applying heat and pressure, the insulating sheet is directly bonded to the metal member, eliminating the need for adhesive tapes. This parameter change resolves the contradiction by providing both reliable adhesion and precise positioning, as the thermocompression bonding process allows for accurate placement of the insulating sheet before bonding occurs.
2Reliability
If a double-sided tape is used to adhere the insulating sheet to the metal member, then the insulating sheet can be fixed to the metal member, but the adhesion process becomes more complex and time-consuming
Solution Approach 1:
The patent extracts and eliminates the adhesive tape from the adhesion system. By using thermocompression bonding, the intermediate adhesive layer is removed entirely, and the insulating sheet is directly bonded to the metal member through heat and pressure. This simplifies the adhesion process by reducing the number of components and steps involved, while maintaining reliable adhesion.
3Reliability
If a double-sided tape is used to adhere the insulating sheet to the metal member, then the insulating sheet can be fixed to the metal member, but the risk of foreign matter attachment increases
Solution Approach 1:
The patent converts the potential harm of using adhesive tapes (foreign matter attachment) into a benefit by eliminating the tape entirely. The thermocompression bonding process uses heat and pressure to directly bond the insulating sheet to the metal member, creating a clean adhesion interface without introducing foreign adhesive materials. This eliminates the source of foreign matter contamination while maintaining strong adhesion.
