Solution Overview
Problem
Existing display devices face challenges in manufacturing very large sizes, requiring tiling configurations where precise alignment is difficult, often necessitating space behind the wall for operators and risking image quality due to deviations between display units.
Innovation Solution
A tiling display device system using magnets and ferromagnetic materials on the rear surface of display panels, allowing for easy attachment, alignment, and maintenance without disassembly, with a mounting jig facilitating precise alignment and detachment for efficient installation and repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanism for fixing is disposed on rear surfaces of display devices to fasten them to the wall, then the display devices can be securely attached, but a space for operators to work is necessarily required behind the wall portion and the structure becomes more complex
Solution Approach 1:
The patent replaces complex mechanical fixing mechanisms with a magnetic attachment system. Magnets embedded in the display device rear surface directly attract to the wall portion, eliminating the need for screws, bolts, or other mechanical fasteners. This substitution simplifies the structure while maintaining secure attachment reliability.
Solution Approach 2:
The patent extracts the fixing function from complex mechanical mechanisms and isolates it into simple magnetic components. By taking out only the essential attachment function and implementing it through magnets, the design removes unnecessary structural complexity while preserving the core functionality of secure wall mounting.
2Reliability
If a mechanism for fixing is used to attach display devices to the wall, then attachment is achieved, but precise alignment is difficult due to mechanism tolerance causing visible boundaries and degraded image quality
Solution Approach 1:
The patent replaces mechanical fixing mechanisms that introduce alignment tolerances with a magnetic field-based attachment system. The magnetic force provides uniform attraction across the contact surface, eliminating the cumulative tolerance errors associated with multiple mechanical fastening points. This enables precise alignment of display devices on the wall without visible boundaries between adjacent units.
3Ease of manufacture
If operators work from behind the wall portion to perform fastening, then the fixing mechanism can be installed, but a working space behind the wall is necessarily required
Solution Approach 1:
The patent inverts the traditional installation approach by enabling operators to perform fastening operations from the front side of the wall rather than requiring access from behind. The magnetic attachment mechanism allows display devices to be positioned and secured by simply bringing them into contact with the wall surface, eliminating the need for rear access spaces and complex behind-wall fastening procedures.
4Area of stationary object
If display devices are tiled to create very large display areas, then the display area is increased, but precise alignment becomes difficult and image quality degrades due to deviations between display units
Solution Approach 1:
The patent replaces mechanical alignment and fixing systems with magnetic attachment that provides uniform force distribution across the entire contact surface. This magnetic field-based approach eliminates the cumulative tolerance errors that occur when multiple mechanical fastening points are used across large tiling configurations, enabling precise alignment even for very large display areas composed of multiple units.
