Multivision Display Frame Alignment for Seamless Video Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multivision display systems face challenges in easily forming configurations with displays positioned vertically and horizontally adjacent to each other, as existing systems often require complex adjustments and suffer from misalignment due to level differences and tolerances, leading to image misalignment on the entire screen.
Innovation Solution
A multivision display system featuring a stand with coupling frames and position adjusters that allow for horizontal and vertical adjustments, including left and right, top and bottom, and front and rear alignment, using screws and rollers to align displays, and spacers to block gaps between adjacent displays, along with wall mounts that enable horizontal movement and precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If displays are fixedly installed on the wall using wall mounts or stands, then the display system is stable and reliable, but it becomes difficult to adjust vertical, horizontal, front, and rear positions of displays
Solution Approach 1:
The coupling frame incorporates adjustable coupling portions that can be repositioned along the coupling groove, transforming a static fixed installation into a dynamic adjustable system. This allows the display position to be modified while maintaining stable support through the rigid coupling structure.
2Ease of manufacture
If displays are installed with fixed coupling frames, then the structure is simple and easy to manufacture, but level differences and misalignments occur due to tolerances
Solution Approach 1:
The coupling frame is divided into modular components including coupling grooves, coupling portions, and adjustable positioning mechanisms. This segmentation allows each component to be manufactured independently with standard tolerances while providing adjustment capability to achieve precise final alignment, overcoming cumulative tolerance issues.
Solution Approach 2:
The coupling portion can be repositioned along the coupling groove to change the effective length and orientation of the coupling, compensating for manufacturing tolerances and achieving precise display alignment without requiring extremely tight manufacturing tolerances on all components.
3Manufacturing precision
If complex adjustment mechanisms are added to eliminate level differences and misalignments, then display alignment precision is improved, but the device complexity increases
Solution Approach 1:
The coupling portion acts as an intermediary element between adjacent displays, providing a simple adjustable connection that absorbs misalignments and level differences. This intermediary mechanism achieves precise alignment without requiring complex adjustment systems on each display unit.
