Foldable Display Hinge Bracket Structure for Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display devices face challenges in protecting the hinge module from damage due to impact forces, as existing designs lack effective mechanisms to absorb or distribute such forces without risking damage to the hinge assembly.
Innovation Solution
The display device incorporates protrusions connected to the hinge assembly that physically contact and are supported by brackets, limiting movement and distributing impact forces, thereby reducing the risk of damage during folding or unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hinge assembly is made more robust to resist impact forces, then the reliability improves, but the device complexity increases
Solution Approach 1:
The hinge assembly is divided into multiple components: hinge body, brackets, and protrusions. The protrusions are segmented elements that extend from the hinge body and contact the brackets, creating a modular shock distribution system that protects the hinge without requiring a completely redesigned robust structure
Solution Approach 2:
The protrusions and brackets form a pre-configured shock absorption mechanism that activates before impact damage can occur. When impact forces are applied, the protrusions contact the brackets first, distributing the force and cushioning the hinge body from direct impact damage
2Reliability
If the hinge assembly is designed to limit movement during folding, then the reliability improves, but the ease of operation deteriorates
Solution Approach 1:
The system transitions from a static hinge structure to a dynamic one where the protrusions and brackets engage and disengage based on the folding state. During normal folding operations, the components move smoothly relative to each other, but upon impact detection, the system dynamically locks to limit movement and protect the hinge
