Conductive Adhesive Tape Electrode Protective Layer for Laminated Glass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices integrated into laminated glass fail shortly after lamination due to the penetration of plasticizers, additives, and external moisture and oxygen from the interlayer adhesive, which react with the conductive adhesive in the conductive adhesive tape electrode, reducing its conductivity and causing device failure.
Innovation Solution
A protective layer is applied to the conductive adhesive tape electrode, sealing it onto the conductive substrate, which prevents the diffusion of plasticizers, additives, and moisture from the interlayer adhesive, thereby maintaining the conductivity of the electronic devices and extending their operational lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no protective layer is applied to the conductive adhesive tape electrode, then the manufacturing process is simple and cost-effective, but the electronic devices fail shortly after lamination due to penetration of plasticizers, additives, and moisture from the interlayer adhesive
Solution Approach 1:
A protective layer is applied to the conductive adhesive tape electrode before the lamination process. This preliminary protective action prevents penetration of plasticizers, additives, and moisture from the interlayer adhesive, thereby maintaining the conductivity and operational lifespan of the electronic devices without requiring complex post-lamination encapsulation methods
2Reliability
If a protective layer is applied to seal the conductive adhesive tape electrode, then the conductivity is maintained and device failure is prevented, but the manufacturing process becomes more complex
Solution Approach 1:
A protective layer in the form of a thin film or coating is applied to the conductive adhesive tape electrode. This flexible protective shell effectively seals the conductive adhesive, preventing penetration of harmful substances from the interlayer adhesive, while maintaining ease of manufacture through simple application processes
