Flexible Display Hinge Plates for Deformation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with flexible displays face challenges in supporting the display when it is subjected to loads, leading to potential damage from deformation.
Innovation Solution
The electronic device incorporates a first and second plate with inclined edge portions between the flexible display and the hinge, forming a folding space where the display can deform, and the plates' inclined surfaces direct the deformation effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flexible display is directly coupled to the hinge without plates, then the device structure is simpler, but the display is vulnerable to damage from loads and deformation
Solution Approach 1:
The first and second plates are introduced as intermediary components between the flexible display and the hinge. These plates absorb and distribute external loads, preventing direct transmission of harmful forces to the display. The plates with inclined edge portions create a controlled folding space that guides deformation away from the display surface, thereby protecting the display while maintaining structural integrity.
2Adaptability or versatility
If the flexible display is allowed to deform freely, then the device is more adaptable to loads, but the display may suffer damage from uncontrolled deformation
Solution Approach 1:
The plates are designed with specific local features - inclined edge portions that create a folding space. This local geometric configuration allows the structure to adapt to loads by directing deformation into a controlled space between the plates, while the display itself remains protected from the deformation forces. The local quality of the inclined surfaces guides the deformation path away from the display.
3Reliability
If rigid support structures are used to protect the display, then the display is better protected, but the device loses flexibility and adaptability
Solution Approach 1:
The support structure is designed to be dynamic rather than rigid. The plates with inclined edge portions create a folding space that allows the structure to adapt its configuration in response to applied loads. This dynamic design enables the structure to provide protection when needed while maintaining flexibility and adaptability under normal operating conditions, resolving the contradiction between rigid protection and flexible adaptability.
