Flexible Display Sliding Mechanism for Hinge Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display apparatuses face issues with the central portion projecting upward or tearing due to lack of elasticity when folded, and the sealed state being damaged due to friction and external forces, especially when using hinges or link members, which also cause mutual interference and inconvenience in use.
Innovation Solution
A flexible display apparatus with a single or dual hinge mechanism that allows the unfixed end portion to slide on a cover plate with a sliding space and guide jaw, supported by fixing plates and folding sensors, preventing the central portion from projecting and the end portion from tearing, while avoiding mutual interference and enhancing usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the flexible display means is directly fixed at both ends, then the structure is simple and stable, but the sealed state is damaged due to lengthwise change during folding and unfolding
Solution Approach 1:
The patent introduces a dynamic absorption mechanism that allows the flexible display means to dynamically adjust its length during folding and unfolding operations. The absorption member (spring or rubber band) provides dynamic compensation for the lengthwise change, transforming the static fixed-end structure into a dynamic system that maintains sealed state integrity while accommodating structural changes.
Solution Approach 2:
The patent changes the physical state or properties of the system by introducing an elastic absorption member that alters the length parameter of the flexible display means during operation. The spring or rubber band changes its length parameter in response to folding/unfolding, allowing the system to adapt to lengthwise changes and maintain the sealed state without direct fixed-end constraints.
2Reliability
If a spring is applied to absorb lengthwise change, then the sealed state is protected, but constant tension locally applied to one end portion destroys the sealed state
Solution Approach 1:
The patent applies the absorption member (spring or rubber band) at a specific local position - the end portion of the flexible display means - rather than distributing tension throughout the entire structure. This localized application provides the necessary lengthwise change absorption while minimizing harmful effects by concentrating the elastic mechanism at a discrete location that can be properly supported by the housing structure.
Solution Approach 2:
The absorption member acts as an intermediary element between the flexible display means and the housing structure. Instead of directly constraining the flexible display means at multiple points, the spring or rubber band serves as a mediator that absorbs lengthwise changes through its elastic properties, reducing direct mechanical stress and preventing sealed state damage.
3Reliability
If the flexible display means is made more elastic to absorb lengthwise change, then the sealed state is maintained, but the end portion tears due to excessive elasticity
Solution Approach 1:
The patent introduces a dynamic absorption mechanism that allows the flexible display means to dynamically adjust its length during folding and unfolding operations. The absorption member (spring or rubber band) provides dynamic compensation for the lengthwise change, transforming the static fixed-end structure into a dynamic system that maintains sealed state integrity while accommodating structural changes.
Solution Approach 2:
The patent changes the physical state or properties of the system by introducing an elastic absorption member that alters the length parameter of the flexible display means during operation. The spring or rubber band changes its length parameter in response to folding/unfolding, allowing the system to adapt to lengthwise changes and maintain the sealed state without direct fixed-end constraints.
4Stability of the object's composition
If hinges are applied to both sides to prevent mutual interference, then the structure is more stable, but the device complexity increases
Solution Approach 1:
The patent divides the hinge mechanism into two separate hinges positioned at different locations on the housing - one hinge for the front surface and another hinge for the rear surface. This segmentation allows each hinge to operate independently, preventing mutual interference during folding and unfolding operations while maintaining overall structural stability.
Solution Approach 2:
The patent resolves the interference problem by moving the hinge mechanism to a different spatial dimension or location. Instead of having both hinges at the same position, the invention places one hinge on the front surface and another on the rear surface, utilizing the third dimension (depth) to separate the hinge locations and eliminate interference.
