Flexible Device Adhesive Structure for Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing flexible modules face issues with increased thickness and layer separation when integrated with mechanical support structures, leading to changes in the neutral layer position during bending, requiring excessive force and potentially disrupting the display effect.
Innovation Solution
A flexible device design incorporating a flexible module, a flexible support structure, and an adhesive structure that allows the module to slide relative to the support structure during bending, maintaining the neutral layer position and preventing layer separation, with the adhesive structure being dot-like or strip-like and positioned between the module and support structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the flexible module is fully attached and fixed to the mechanical support structure, then the support and fixation are improved, but the thickness of the flexible module increases and the neutral layer position changes
Solution Approach 1:
The adhesive structure is divided into multiple discrete adhesive layers positioned at specific locations between the flexible module and mechanical support structure, rather than using a continuous full-surface attachment. This segmentation allows the module to be supported at key points while maintaining flexibility and preventing excessive thickness increase.
Solution Approach 2:
The adhesive structure provides localized attachment at specific positions between the flexible module and mechanical support structure, rather than uniform full-surface bonding. This local quality approach maintains support where needed while preserving flexibility and neutral layer position in other regions.
2Stability of the object's composition
If the flexible module is fully attached and fixed to the mechanical support structure, then the support and fixation are improved, but the layers of the flexible module easily separate from each other
Solution Approach 1:
The adhesive structure is segmented into discrete adhesive layers positioned at specific locations, which prevents the flexible module layers from separating while maintaining support. The segmented design allows each layer to remain bonded at critical points without creating excessive stress that would cause separation.
Solution Approach 2:
The adhesive structure acts as an intermediary element between the flexible module and mechanical support structure, providing controlled attachment that prevents layer separation. The adhesive layers mediate the connection in a way that maintains the integrity of the flexible module layers while still providing necessary support.
3Stability of the object's composition
If the flexible module is fully attached and fixed to the mechanical support structure, then the support and fixation are improved, but a larger bending force is required
Solution Approach 1:
The adhesive structure is segmented into discrete layers positioned at specific locations, which reduces the overall bonding area and allows the flexible module to bend more easily. This segmentation maintains necessary support while reducing the bending force required compared to full-surface attachment.
Solution Approach 2:
The adhesive structure provides localized support at specific positions rather than uniform full-surface bonding, which maintains structural integrity where needed while allowing easier bending in other regions. This local quality approach reduces the overall bending force required.
4Stability of the object's composition
If the flexible module is fully attached and fixed to the mechanical support structure, then the support and fixation are improved, but the display effect is adversely affected
Solution Approach 1:
The adhesive structure is segmented into discrete layers positioned at specific locations, which preserves the display quality of the flexible module. The segmented design ensures that the adhesive does not interfere with the display surface or cause layer separation that would affect the display effect, while still providing necessary support.
Solution Approach 2:
The adhesive structure provides localized attachment at specific positions away from the display surface, maintaining the display effect while providing support. The local quality approach ensures that the adhesive does not adversely affect the display quality while still achieving the necessary support and fixation.
