Magnetic Tiled Display Assembly for Front-Side Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tiled displays face challenges in precise alignment and real-time adjustment of display devices when attached to a wall, leading to visible boundaries and reduced image quality due to machining and adhesion tolerances, making it difficult to check and maintain the spacing and alignment from the front.
Innovation Solution
A method and tool using magnets with rotatable poles to attach and detach display devices from a wall, allowing for real-time alignment and adjustment from the front, reducing the impact on devices and simplifying the fastening process with fewer components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If display devices are attached to the wall from the back using conventional fastening members, then the attachment is secure, but the alignment precision deteriorates due to inability to check from the front
Solution Approach 1:
The patent inverts the conventional attachment approach by allowing display devices to be attached to the wall from the front rather than from the back. The attaching member engages with the display device case from the front surface, enabling the operator to visually check alignment in real-time while maintaining secure attachment. This inversion resolves the contradiction by making the previously hidden alignment checkable without compromising attachment security.
2Reliability
If multiple fastening members are used to secure display devices, then the attachment reliability improves, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single attaching member that combines both attachment and alignment functions. The attaching member integrates a fastening structure that secures the display device to the wall while simultaneously providing alignment features such as guide portions that ensure precise positioning. This consolidation reduces the number of separate components needed, thereby reducing device complexity while maintaining or even improving attachment reliability through the integrated design.
Solution Approach 2:
The attaching member is designed as a multi-functional component that performs multiple tasks: it attaches the display device to the wall, aligns the device in the correct position, and allows for easy detachment and reattachment. This universal design eliminates the need for separate alignment tools and fastening mechanisms, reducing overall system complexity while ensuring reliable and precise attachment.
3Manufacturing precision
If display devices are firmly fixed to eliminate boundaries, then the image quality improves, but the ease of maintenance deteriorates
Solution Approach 1:
The patent implements a dynamic attachment system where the attaching member allows for easy detachment and reattachment of display devices. The attaching member engages with the display device case through a mechanism that provides firm fixation during operation (eliminating boundaries and ensuring image quality) but allows for simple removal when maintenance is needed. This dynamic capability resolves the contradiction by enabling both secure fixation for optimal image quality and easy accessibility for maintenance activities.

AI summary
There is provided a tiled display including: a plurality of display devices; a plurality of first magnets in contact with a surface of each of the display devices; a wall portion able to be attached to and detached from the display devices; and a plurality of second magnets disposed on a surface of the wall portion such that they are in line with the first magnets, respectively. The second magnets are movable in a direction perpendicular to the surface of the wall portion. Accordingly, it is possible to attach/release the plurality of display devices to/from the wall portion by forming an attractive force and a repulsive force between the first magnets and the second magnets.
