Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for electronic image display panels struggle with achieving uniformity and coplanarity of adjacent edges, leading to undesirable seams and brightness variations when multiple panels are assembled, especially when the backing surface is uneven or bent.
Innovation Solution
A hidden magnetic fastener system that allows for adjustable positioning and alignment of display panel sections from the front surface, using magnetic elements and adjustable screws to ensure coplanarity and uniform spacing, reducing the visibility of seams and improving image uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional mounting systems are used to assemble multiple display panels, then the panels can be mounted on the wall, but visible seams and brightness variations appear due to spacing irregularities and non-coplanar edges
Solution Approach 1:
The patent replaces traditional mechanical adjustment systems (screws, bolts, manual positioning) with a magnetic field-based system. Magnets embedded in the mounting plate and corresponding magnetic elements on the rear of display sections enable automatic alignment and positioning through magnetic attraction, eliminating visible seams and ensuring uniform spacing without requiring manual mechanical adjustment.
Solution Approach 2:
The patent changes the physical state and properties of the mounting system by introducing magnetic fields as the primary positioning mechanism. The magnetic force provides continuous adjustable attraction between the mounting plate and display sections, allowing precise control of spacing and alignment parameters while maintaining ease of installation and adjustment.
2Area of stationary object
If display panel sections are tightly spaced to cover larger area, then the array covers more surface, but visible seams appear due to pitch variations
Solution Approach 1:
The magnetic positioning system automatically maintains uniform spacing between adjacent display sections by balancing magnetic attraction forces. This ensures consistent LED pitch across the entire array even when covering large areas, preventing visible seams caused by pitch variations while enabling seamless expansion of the display array.
3Ease of operation
If manual adjustment of mounting position is performed, then some positioning flexibility is achieved, but multiple iterative adjustments are required and rear access is needed
Solution Approach 1:
The magnetic field-based positioning system eliminates the need for manual mechanical adjustment and rear access. Magnets provide automatic self-alignment and positioning when display sections are installed, achieving precise coplanar alignment and uniform spacing in a single operation without requiring iterative adjustments or access to the rear of the mounting structure.
4Adaptability or versatility
If display sections are mounted on uneven or bowed backing surfaces, then installation is possible, but edge coplanarity cannot be achieved
Solution Approach 1:
The magnetic positioning system compensates for uneven or bowed backing surfaces by using adjustable magnetic attraction forces to maintain uniform spacing and coplanar alignment of display section edges. The magnetic field provides continuous force adjustment that adapts to surface irregularities, ensuring edge coplanarity is achieved even when mounted on non-flat surfaces.
