Foldable Hinge Structure With Dynamic Screen Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable devices face screen damage due to contact with internal support structures during folding, and existing clearance solutions lead to screen sagging when unfolded, affecting user experience.
Innovation Solution
A hinge structure with a movable support structure that changes posture as the swing arms rotate, providing dynamic support to the screen by contacting the swing arms at different positions, reducing screen squeezing in the folded state and supporting it in the unfolded state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clearance space is set at the internal support structure to avoid screen contact during folding, then screen damage is prevented, but the screen sinks when unfolded affecting user experience
Solution Approach 1:
The support structure is designed to be movable rather than fixed, allowing it to dynamically adjust its position and posture according to the folding state. During folding, the support structure moves to provide clearance and avoid screen contact. During unfolding, it moves to provide support and prevent screen sinking, thus resolving the contradiction between screen protection and user experience.
2Ease of operation
If the support structure is fixed to prevent screen sinking, then screen support is improved, but the screen is squeezed during folding causing potential damage
Solution Approach 1:
The support structure transitions from a fixed design to a movable one that can adapt its position. When unfolded, the support structure maintains contact with the screen to prevent sinking. When folded, it moves away to avoid squeezing and potential damage, thus dynamically balancing screen support and screen protection requirements.
Solution Approach 2:
The support structure is designed to automatically adjust its position based on the folding state without external control. The mechanical linkage between the swing arms and support structure enables it to self-adjust, moving to appropriate positions that simultaneously satisfy both screen support and screen protection requirements.

AI summary
Disclosed are a hinge structure and a foldable device. The hinge structure includes: a first swing arm and a second swing arm; and a support structure, disposed between the first swing arm and the second swing arm. During rotation of the first swing arm and the second swing arm, two ends of the support structure are configured to contact the first swing arm and the second swing arm respectively, enabling the support structure to move between a first position and a second position. The posture of the support structure in the first position is different from the posture of the support structure in the second position.
