Foldable Screen Hinge Sliding Structure for Tensile Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible screens are prone to damage due to large tensile forces, necessitating a compensation structure to reduce or avoid damage during bending.
Innovation Solution
An electronic device with a first and second frame, a bendable hinge between them, and a flexible member covering both frames, featuring a sliding mechanism driven by a supporting member to reduce tensile forces on the flexible member during bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible screen is bent, then the device achieves foldability and flexibility, but the flexible screen is subjected to large tensile force and is easily damaged
Solution Approach 1:
The patent introduces a dynamic compensation mechanism consisting of a sliding member and supporting member that automatically adjusts during bending. The sliding member moves along the bending axis direction, dynamically compensating for dimensional changes and reducing tensile force on the flexible screen throughout the bending process
Solution Approach 2:
The supporting member acts as an intermediary between the first and second housings, providing mechanical support and guiding the sliding member's movement. This intermediary structure absorbs and distributes the stress during bending, protecting the flexible screen from direct tensile damage
2Reliability
If a compensation structure is added to reduce tensile force, then the flexible screen is protected from damage, but the device complexity increases
Solution Approach 1:
The sliding member is designed as a thin-walled hollow cylindrical structure that provides mechanical compensation functionality while maintaining flexibility and minimizing added complexity. The hollow cylindrical design allows for movement along the bending axis while maintaining structural integrity
Solution Approach 2:
The compensation mechanism is segmented into distinct functional components: the sliding member that moves along the bending axis, and the supporting member that provides structural guidance. This segmentation allows each component to perform its specific function efficiently while keeping the overall structure manageable

AI summary
The present disclosure provides an electronic device, which comprises a first frame, a second frame, a bendable hinge located between the first frame and the second frame, and a flexible member covering the first frame, the second frame, and the bendable hinge. Wherein, the electronic device further comprises a sliding member located on one side of the bendable hinge, and a supporting member connecting the sliding member and the first frame. The flexible member connects the first frame and the second frame. When the bendable hinge is bent, the supporting member can drive the sliding member to slide relative to the bendable hinge, and the flexible member can drive the second frame to slide relative to the bendable hinge.
