Foldable Display Hinge Structure for Larger Bending Arc
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable electronic devices face challenges in accommodating the flexible screen after folding, as current mechanisms do not effectively match the surface of the mechanism with the size of the flexible screen before and after folding, leading to potential damage.
Innovation Solution
A hinge mechanism comprising a fixed bracket, support mechanism, and rotary mechanism with specific connection members and support members that allow for a flexible display panel to be bent and folded, ensuring adequate accommodation and preventing damage by allowing a larger arc for bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional hinge mechanism is used, then the structure is simple, but the flexible display panel cannot be properly accommodated during folding, leading to potential damage
Solution Approach 1:
The hinge mechanism is divided into multiple support members (first support member, second support member, third support member, fourth support member) that can independently move and adjust. Each support member is connected through rotatable and slidable connections, allowing segmented motion that accommodates the flexible display panel during folding without requiring a completely complex overall structure.
Solution Approach 2:
The support members are arranged in a specific spatial configuration where they extend in different directions from the fixed bracket. The first and third support members extend in a first direction, while the second and fourth support members extend in a second direction, creating a multi-dimensional support structure that provides adequate accommodation space for the flexible display panel during folding operations.
2Volume of moving object
If the folding arc is reduced to improve portability, then the device becomes more compact, but the flexible display panel may be damaged due to excessive bending
Solution Approach 1:
The support members act as intermediary elements between the fixed bracket and the flexible display panel. During folding, these support members provide a gradual transition and adequate accommodation space, mediating the bending process to prevent excessive stress concentration on the flexible display panel while still achieving compact folded dimensions.
Solution Approach 2:
The hinge mechanism allows dynamic adjustment of the folding arc through the coordinated rotation and sliding of multiple support members. This enables optimization of the bending radius parameter to maintain it above the critical threshold for flexible display panel safety, while still achieving sufficient compactness for portability.
