LED Screen Edge Locking Structure With Multi-Stage Cylinder Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The edge locking structure in large-screen LED display screens is prone to loosening, resulting in a poor locking effect due to the single-stage driving mechanism of the lock cylinder.
Innovation Solution
An edge locking apparatus with a multi-stage linkage mechanism involving a lock seat, lock cylinder, rotating piece, first driving piece, and second driving piece, where the first driving piece drives the rotating piece to rotate the second driving piece, enabling the lock cylinder to rotate from the inserting position to the locking position, thereby stabilizing the edge locking structure and enhancing the locking effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-stage driving piece is used to drive the lock cylinder, then the device complexity is reduced, but the reliability of the locking mechanism deteriorates due to loosening
Solution Approach 1:
The single-stage driving piece is segmented into two independent driving pieces: a first driving piece that drives the lock cylinder to move between retracting and inserting positions, and a second driving piece that drives the lock cylinder to rotate from inserting position to locking position. This segmentation eliminates the loosening problem by separating the linear motion and rotational motion functions, thereby improving reliability while maintaining acceptable device complexity.
2Reliability
If a multi-stage linkage mechanism is used to prevent loosening, then the reliability of the locking mechanism is improved, but the device complexity increases
Solution Approach 1:
The lock cylinder serves as an intermediary component that receives motion from two independent driving pieces. The first driving piece controls its linear movement, while the second driving piece controls its rotation. This intermediary approach allows the system to achieve reliable locking without requiring a complex integrated mechanism, as each driving piece can be designed and manufactured independently.
