Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive tapes with electrically releasable adhesive layers lack sufficient mechanical robustness and impact strength, as the constituents of the tape influence mechanical properties in complex ways.
Innovation Solution
The adhesive tape comprises a plurality of interconnected layers, including an electrically releasable adhesive layer, an electrically conductive carrier layer, and an adhesive layer, with a specific thickness ratio of the sum of the conductive and adhesive layers to the total thickness equal to or less than 1.0, ensuring high impact strength and reliable electrical releasability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the adhesive tape includes multiple layers with specific thickness ratios to improve impact strength, then mechanical robustness is enhanced, but the complexity of the tape structure increases
Solution Approach 1:
The adhesive tape is divided into multiple functional layers including an electrically releasable adhesive layer, a carrier layer, and at least one adhesive layer. This segmentation allows each layer to contribute specifically to impact strength while maintaining electrical releasability, resolving the contradiction between enhanced strength and structural complexity.
Solution Approach 2:
The tape employs a composite structure combining different material layers with specific thickness ratios. The carrier layer provides mechanical support while the adhesive layers provide bonding functionality, creating a composite material system that achieves high impact strength without excessive complexity.
2Strength
If the thickness ratio of conductive and adhesive layers to total thickness is controlled to enhance impact strength, then mechanical robustness improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies that the ratio of the sum of the first thickness and each second thickness to the sum of each third thickness is equal to or less than 1.0. This parameter control ensures optimal balance between impact strength and electrical releasability while providing clear manufacturing guidelines to manage precision requirements.
3Ease of operation
If an electrically releasable adhesive layer is used to enable electrical debonding, then ease of operation improves, but mechanical strength decreases
Solution Approach 1:
The invention merges the electrically releasable adhesive layer with additional adhesive layers and a carrier layer to create a unified structure. This combination maintains the electrical debonding functionality while the carrier layer and additional adhesive layers provide the necessary mechanical strength, resolving the contradiction between ease of operation and mechanical robustness.
