Magnetic LED Display Board Frame for Fast Module Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED display boards require disassembly of all modules for replacement, suffer from installation errors due to processing dispersion, and impose excessive load on walls, limiting installation locations.
Innovation Solution
An LED display board design featuring a grid of edge, vertical, and horizontal beams with magnetic attachments and hollow aluminum profiles, allowing modular installation without cabinets, reducing weight and correcting installation errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cabinets are manufactured by die casting and bolted to the wall frame, then the LED modules can be installed on the wall frame, but installation errors occur due to processing dispersion during molding, and excessive bolt usage is required, and installation time is excessively taken
Solution Approach 1:
The cabinet is divided into multiple cabinet sections, each with independent positioning structures. The first cabinet section includes a first positioning structure with positioning protrusions, while the second cabinet section includes a second positioning structure with positioning grooves. This segmentation allows each section to be independently positioned and assembled, reducing cumulative installation errors and simplifying the overall installation process.
2Strength
If multiple cabinets are installed in the wall frame, then the LED display can be formed, but stress due to the load of the cabinets may be applied to the wall, and installation is only possible in a wall that can bear the load of the cabinets
Solution Approach 1:
A wall mounting structure is introduced as an intermediary between the wall and the cabinet sections. This wall mounting structure includes mounting plates that distribute the load across multiple attachment points and mounting brackets that provide mechanical support. By introducing this intermediary structure, the load is dispersed rather than concentrated, allowing installation on walls with lower load-bearing capacity and expanding installation location flexibility.
3Ease of operation
If all LED modules are installed in the cabinet before replacement, then the cabinet can be installed on the wall frame, but in order to replace one LED module, all LED modules installed in the cabinet need to be disassembled
Solution Approach 1:
The cabinet is segmented into multiple independent cabinet sections, where each section can house a subset of LED modules. This segmentation allows individual cabinet sections to be accessed and modified independently. When replacement is needed, only the specific cabinet section containing the target LED module needs to be accessed, while other sections remain in place, significantly reducing replacement time and effort.
Solution Approach 2:
The cabinet sections are designed with detachable connections through the positioning structures (protrusions and grooves), allowing dynamic assembly and disassembly. This dynamic design enables quick access to specific LED modules by simply detaching the relevant cabinet section, replacing the module, and reattaching the section, without requiring disassembly of the entire cabinet system.
