Flexible Display Hinge Housing Cushioning for Shock Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with flexible displays are vulnerable to external shocks, particularly in the bending area, which can lead to surface deterioration due to shear stress between the housing structure and the display.
Innovation Solution
The electronic device incorporates a hinge housing with protruding portions and cushioning members to absorb external shocks, allowing the flexible display to move within a certain range and preventing direct collision with rigid internal structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flexible display is attached to the housing structure to be movable to relieve shear stress, then the surface quality deterioration is reduced, but the flexible display may collide with internal structures and get damaged
Solution Approach 1:
The patent applies beforehand cushioning by placing cushioning members between the flexible display and the housing structure in advance. These cushioning members are positioned at locations where collision might occur, providing protective cushioning before actual shock events happen. This resolves the contradiction by allowing the display to move freely while being pre-protected against collision damage.
Solution Approach 2:
The cushioning members act as intermediary elements between the flexible display and the rigid housing structure. When collision occurs, the cushioning members intervene to absorb and distribute the impact force, preventing direct contact between the display and hard surfaces. This mediator approach allows the display to be movable while protecting it from collision harm.
2Object-affected harmful factors
If the flexible display is made movable to absorb external shock, then the shock resistance is improved, but the device structure becomes more complex
Solution Approach 1:
The patent utilizes the flexibility of the display itself as a shock-absorbing mechanism. The flexible display can deform and move under external shock, converting impact energy into deformation energy. This approach improves shock resistance without adding complex mechanical shock-absorbing structures, as the display's inherent flexibility serves the dual purpose of display function and shock absorption.
Solution Approach 2:
The flexible display serves itself by using its own flexibility and movability to absorb external shocks. The display's ability to move and deform under impact provides inherent shock protection without requiring separate active shock-absorbing mechanisms. This self-service approach improves shock resistance while minimizing structural complexity.
