Slit Adhesive Member Layout for Flexible Display Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in maintaining structural integrity and flexibility while being compact and functional, particularly in the integration of display components and supporting structures.
Innovation Solution
An adhesive member with slits arranged in specific directions and widths is used between a supporting member and a display film, providing structural support and flexibility by allowing for controlled movement and alignment of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive member is used to bond supporting member and display film, then structural integrity is improved, but flexibility and movement capability deteriorate
Solution Approach 1:
The adhesive member is divided into multiple segments by forming slits that extend in the first direction, creating a plurality of separated adhesive portions. This segmentation allows each segment to move independently, providing flexibility while maintaining overall bonding strength between the supporting member and display film.
Solution Approach 2:
Different regions of the adhesive member are designed with different properties: the slits create regions of flexibility while the adhesive portions maintain bonding strength. The width of slits and adhesive portions can be varied locally to optimize both structural integrity and flexibility in different areas.
2Volume of moving object
If adhesive member is made compact, then device size is reduced, but alignment precision of components deteriorates
Solution Approach 1:
The alignment function is shifted from the planar dimension to the thickness dimension by forming protrusions that extend in the second direction. This allows precise alignment to be achieved through vertical engagement rather than horizontal positioning, enabling compact design without sacrificing alignment precision.
Solution Approach 2:
Protrusions and corresponding recesses act as intermediary alignment features between the adhesive member and other components. These intermediary structures provide precise positioning while allowing the overall device to maintain a compact form factor.
3Adaptability or versatility
If adhesive member includes multiple slits for flexibility, then adaptability is improved, but structural strength deteriorates
Solution Approach 1:
The width of slits and adhesive portions can be adjusted as parameters to optimize the balance between flexibility and bonding strength. By controlling the width ratios and spacing of slits, the adhesive member achieves sufficient flexibility for component movement while maintaining adequate bonding strength for structural integrity.
