Magnetic Level Adjustment for Display Panel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The alignment of front levels between neighboring display assemblies in a display device is challenging, leading to issues with screen quality due to differences in panel heights, requiring time-consuming adjustments to achieve proper leveling.
Innovation Solution
A display system with a level adjustment device that uses rotating magnets and worm gears to adjust the position of display modules relative to their supporters, allowing for easy alignment of front levels through magnetic coupling and mechanical translation, facilitated by a motor and sensor-controlled mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual alignment adjustment is used to level display panels, then front level alignment between neighboring display assemblies is improved, but installation time increases significantly
Solution Approach 1:
The patent incorporates adjustable support legs with level adjustment mechanisms into the display stand structure before installation. These mechanisms include threaded rods, locking nuts, and adjustment knobs that allow for pre-adjustment of each display panel's height and tilt angle. The support structure includes built-in adjustment ranges that accommodate common installation surface irregularities, enabling installers to quickly level multiple display panels without time-consuming manual alignment procedures.
2Reliability
If display assemblies are magnetically coupled to supporters, then electrical connectivity is maintained, but adjustment of display module position becomes difficult
Solution Approach 1:
The patent divides the coupling system into separate functional zones: magnetic coupling areas for electrical connectivity and mechanical adjustment areas for position control. The support structure includes adjustment mechanisms (threaded rods, locking nuts, adjustment knobs) that are positioned away from the magnetic coupling interfaces. This segmentation allows the magnetic connections to remain undisturbed during mechanical adjustments, enabling position changes without compromising electrical connectivity.
Solution Approach 2:
The patent implements a dynamic coupling system where the magnetic connection strength can be modulated during adjustment operations. The support structure includes features that allow temporary reduction of magnetic holding force during position adjustments, followed by restoration of full magnetic coupling once alignment is achieved. This dynamic behavior enables easy repositioning while maintaining reliable electrical connectivity during normal operation.
