Movable Support Plate Hinge for Foldable Wire Routing Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with foldable screens face a short service life due to inadequate wire arrangement management in their bent state, leading to premature wear and tear.
Innovation Solution
A hinge system with rotating assemblies and a supporting plate that actively controls the bending shape of the wire arrangement, allowing smoother movement between unfolded and folded positions, thereby extending the service life of both the wire arrangement and the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the wire arrangement is arranged in a bent state to provide enough length in folded state, then the wire length requirement is satisfied, but the wire arrangement experiences wear and tear reducing 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 hinge rotates between unfolded and folded positions, the supporting plate moves actively to maintain an optimal bending radius for the wire arrangement, transforming a static wire routing problem into a dynamic control system that adapts to different hinge states
Solution Approach 2:
The invention changes the bending radius parameter of the wire arrangement by moving the supporting plate in the thickness direction. This parameter adjustment ensures that the wire arrangement always bends along a smooth arc with adequate radius, preventing excessive stress and wear while maintaining sufficient wire length in the folded state
2Device complexity
If a simple rotating hinge structure is used, then the device complexity is reduced, but the wire arrangement cannot be actively controlled leading to wear
Solution Approach 1:
The supporting plate serves multiple functions: it provides structural support for the wire arrangement, acts as a lever arm for the rotating assemblies, and functions as a movable element that actively controls the wire bending trajectory. This multi-functionality adds control capability without requiring separate dedicated components
Solution Approach 2:
The supporting plate acts as an intermediary element between the rotating assemblies and the wire arrangement. It translates the rotational motion of the hinge into controlled movement of the wire routing path, mediating the interaction between mechanical motion and wire stress distribution
