Flexible Screen Hinge Telescopic Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinges for flexible screens fail to maintain a constant support surface length during bending and flattening, making it difficult to commercialize flexible screens for mobile terminals like mobile phones and notebooks.
Innovation Solution
A hinge with a telescopic positioning device comprising a left-side and right-side telescopic connection frame, an intermediate connection frame, and a synchronous reverse transmission mechanism, which maintains the flexible screen's support surface length unchanged by synchronously rotating the telescopic connection frames in opposite directions, ensuring stable positioning and easy operation during folding and unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional hinge structure is used for flexible screens, then the hinge structure is simple, but the support surface length changes during bending and flattening
Solution Approach 1:
The hinge structure employs dynamic telescopic connection frames that can extend and contract to compensate for length changes during screen bending. The connection frames include telescopic mechanisms with sliding components that adjust the effective length dynamically, ensuring the support surface length remains constant while the screen transitions between folded and unfolded states.
Solution Approach 2:
The hinge is divided into multiple independent links and connection frames that can move relative to each other. The telescopic connection frame is segmented into extendable and contractable portions, allowing each segment to contribute to maintaining the overall support surface length while enabling the necessary structural adjustments during screen flexing.
2Manufacturing precision
If the hinge structure is made complex to maintain constant support surface length, then the support surface length remains constant, but the ease of operation deteriorates
Solution Approach 1:
The telescopic connection frame incorporates self-adjusting mechanisms that automatically extend or contract based on the screen's bending state without requiring user intervention. The synchronous reverse transmission mechanism and positioning structures work autonomously to maintain proper positioning, allowing users to simply fold or unfold the screen without worrying about manual adjustment of the hinge components.
Solution Approach 2:
The positioning structure includes feedback mechanisms such as positioning slots and synchronous reverse transmission that detect the screen's position and automatically adjust the telescopic connection frame accordingly. This feedback system ensures the hinge maintains the correct support surface length regardless of the screen's state, providing consistent operation experience.
3Manufacturing precision
If telescopic connection frames are added to maintain support surface length, then the support surface length remains constant, but the device complexity increases
Solution Approach 1:
The telescopic connection frame serves multiple functions simultaneously: it maintains support surface length, provides positioning for the flexible screen, enables synchronous reverse transmission between left and right sides, and allows for compact folding. By integrating these functions into a single component system, the patent avoids adding separate mechanisms for each function, thereby reducing overall device complexity despite the enhanced capabilities.
