Hovering Hinge Assembly for Stable Foldable Device Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable electronic devices rely heavily on hinge assemblies for folding and unfolding, but these devices lack the ability to maintain specific target bending states, limiting their folding manner.
Innovation Solution
A hinge assembly with a hovering mechanism that includes a rotating assembly and a position limiting mechanism, where the first limiting part and second limiting part coordinate to restrict the rotation of the rotating assembly, maintaining the hinge assembly at a target position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hinge assembly relies only on rotation for folding and unfolding, then the device can achieve basic folding function, but the device cannot maintain specific target bending states
Solution Approach 1:
The hinge assembly is segmented into multiple functional components: a rotating assembly for basic folding motion, and a hovering mechanism with position limiting members that provide discrete stopping positions. This segmentation allows the system to maintain multiple stable bending states while preserving the fundamental folding capability.
Solution Approach 2:
The hinge assembly transitions from a purely dynamic rotating system to a hybrid system that combines continuous rotation with discrete static positioning. The position limiting members enable the rotating assembly to dynamically move between multiple stable states, enhancing adaptability while maintaining stability at each position.
2Stability of the object's composition
If the hinge assembly adds a hovering mechanism with position limiting members, then the device can maintain target bending states, but the device complexity increases
Solution Approach 1:
The hovering mechanism is merged with the rotating assembly such that the position limiting members are integrated into the existing rotational structure. The first and second position limiting members cooperate with each other within the same rotational path, combining the hovering and rotating functions into a unified mechanism rather than separate systems.
Solution Approach 2:
The position limiting members serve multiple functions: they limit the rotation angle to specific values, provide stable positioning at target bending states, and work cooperatively within the single rotational movement of the rotating assembly. This multi-functionality reduces the need for additional separate positioning mechanisms.
