Foldable Screen Hinge Structure for Smoother Wire Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The service life of wire arrangements in electronic devices with foldable screens is compromised due to inadequate bending shape control, leading to premature wear and tear.
Innovation Solution
A hinge mechanism with rotating assemblies and a supporting plate that allows active control of the wire arrangement's bending shape by moving the supporting plate in the thickness direction of the base, ensuring a smoother bending form regardless of the device's state, thereby extending the service life of both the wire arrangement and the electronic device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the wire arrangement is bent to provide sufficient length in folded state, then the wire length requirement is met, but the bending shape control is inadequate leading to wear and reduced service life
Solution Approach 1:
The supporting plate is designed to dynamically adjust its position in the thickness direction of the base through the rotating assemblies. As the foldable screen transitions between folded and unfolded states, the supporting plate automatically moves to maintain optimal bending shape of the wire arrangement, transforming a static structure into a dynamic one that adapts to different states and prevents wear.
2Device complexity
If the supporting plate is fixed, then the structure is simple, but the bending shape of wire arrangement cannot be actively controlled
Solution Approach 1:
The hinge structure is segmented into multiple functional components: the base, the supporting plate, and rotating assemblies with rotating members. This segmentation allows the supporting plate to be independently controlled by the rotating assemblies, enabling precise active control of the wire arrangement's bending shape while maintaining overall structural organization and manageable complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The hinge mechanism improves the service life of the wire arrangement and the electronic device by maintaining a smoother bending shape during unfolding and folding, reducing wear and tear, and enhancing the overall durability and usability of the device.
Implementation Method 1
a first rotating assembly and a second rotating assembly, each of the first rotating assembly and the second rotating assembly being rotatably disposed on the base between an unfolded position and a folded position

AI summary
A hinge includes: a base; a supporting plate; and a first rotating assembly and a second rotating assembly, each of the first rotating assembly and the second rotating assembly being rotatably arranged on the base between an unfolded position and a folded position, and at least one of the first rotating assembly and the second rotating assembly fitting with the supporting plate so as to move the supporting plate in a thickness direction of the base. The hinge of the present disclosure can actively control the bending shape of the wire arrangement, such that the bending shape of the wire arrangement is smoother, so as to improve the service life of the wire arrangement, and thereby improve the service life of the electronic device.
