Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display devices struggle to stably maintain their folded and flattened states due to instability, affecting user experience.
Innovation Solution
A foldable display device design featuring a hinge assembly with a fixing, rotating, and locking mechanism, including elastic assemblies and abutting members that securely hold the supports in preset angles, preventing folding noise and ensuring stability in various states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional hinge structure is used without locking mechanism, then the device can fold and flatten freely, but it cannot stably maintain its folded state and flattened state
Solution Approach 1:
The locking assembly is pre-configured with abutting members and elastic assemblies that automatically engage when the support rotates to preset angles, eliminating the need for external force to maintain stability
Solution Approach 2:
The elastic assembly automatically pushes the abutting member against the support to generate locking force, enabling the hinge assembly to self-maintain stable states without external intervention
2Stability of the object's composition
If a locking mechanism is added to stabilize the folded and flattened states, then stability is improved, but the device complexity increases
Solution Approach 1:
The hinge assembly is divided into distinct functional modules: a rotating assembly for movement and a locking assembly for stabilization, allowing independent optimization of each subsystem
Solution Approach 2:
The abutting member serves dual functions: it engages with the support to provide locking force for stability, and its rotation with the rotating member enables automatic engagement and disengagement during folding operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design allows for stable maintenance of folded and flattened states without external force, reducing noise during folding and enabling smooth transitions between states, enhancing user experience by preventing sudden movements and sounds.
Implementation Method 1
a first elastic assembly disposed on the fixing assembly; and a second elastic assembly disposed on the fixing assembly; wherein when the foldable display device is in a preset state, the first elastic assembly and the first abutting member abut against each other, and the second elastic assembly and the second abutting member abut against each other

AI summary
A foldable display device is provided. A first support is connected to a first rotating member, and a second support is connected to a second rotating member. The first rotating member is rotatably connected to a fixing assembly and connected to a first abutting member. A second rotating member is rotatably connected to the fixing assembly and connected to a second abutting member. When the foldable display device is in a preset state, the first abutting member and a first elastic assembly abut against each other, and a second abutting member and a second elastic assembly abut against each other.
