Foldable Hinge Module With Variable Free-Stop Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable electronic devices with fixed free stop function angles pose difficulties in unfolding or folding with one hand, as the fixed angle range restricts user convenience.
Innovation Solution
A hinge module with a flexible section that allows the free stop function to be implemented at varying angles, enabling the foldable electronic device to adapt to different user scenarios, such as one-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flex section angle range is reduced to facilitate one-handed operation, then easier unfolding and folding is achieved, but the usability of the free stop function is restricted
Solution Approach 1:
The system dynamically switches between different angle ranges for the flex section based on the detected operation mode. During folding/unfolding operations, a smaller angle range is used to reduce resistance. During usage modes (viewing, photographing, editing), a larger angle range is activated to provide stable stopping positions. This temporal separation of functions allows the system to optimize for one-handed operation without permanently restricting free stop functionality.
Solution Approach 2:
The hinge module periodically transitions between different operational states with different angle ranges. The control module detects the current state (folding, unfolding, or usage) and adjusts the flex section angle range accordingly. This periodic switching between configurations allows the system to provide appropriate mechanical characteristics for each phase of operation, resolving the contradiction between ease of operation and adaptability.
