Elastic Member Cutting Structure for Foldable Display Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing elastic members in foldable display devices face stability issues due to protruding bridge parts after cutting, leading to potential safety hazards and increased bezel regions.
Innovation Solution
The elastic member module features a cutting region with concave portions and a connection part that allows the bridge part to be cut internally, preventing protrusion and reducing the bezel region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bridge part is cut to separate the elastic member from the frame, then the elastic member can be applied to the display device, but a remaining region of the bridge part protrudes outward causing stability problems
Solution Approach 1:
The harmful remaining region of the bridge part is extracted and removed through the cutting region design. The cutting region includes first and second cutting lines that extend into the bridge part, allowing the protruding remaining region to be completely removed while maintaining the functional connection between the elastic member and frame during assembly.
Solution Approach 2:
The cutting region is pre-formed in the bridge part before the elastic member is applied to the display device. The first and second cutting lines are预先 designed to extend into the bridge part, so that when cutting occurs, the remaining region is already positioned to be completely removed, preventing protrusion before it becomes a problem.
2Adaptability or versatility
If the bridge part is cut to separate the elastic member from the frame, then the elastic member can be applied to the display device, but the bezel region of the elastic member increases
Solution Approach 1:
The cutting region design extracts and removes the excess bridge part material that would otherwise form part of the bezel region. By extending the cutting lines into the bridge part, the design ensures that only the necessary connection portion remains, minimizing the bezel area while maintaining structural integrity.
3Ease of manufacture
If the bridge part remains connected to the frame, then the elastic member can be stored with the frame, but the bridge part cannot be cut and remains protruding
Solution Approach 1:
The harmful protruding remaining region is extracted and removed through the cutting region. The first and second cutting lines are designed to extend into the bridge part, ensuring complete removal of the protruding portion while maintaining the functional connection during storage and assembly processes.
Solution Approach 2:
The cutting region acts as an intermediary structure that allows the bridge part to be properly separated. The first and second cutting lines create a controlled separation zone that eliminates the harmful remaining region while maintaining the necessary connection for storage and assembly convenience.
