Solution Overview
Problem
Existing LED display devices face challenges in easily assembling and disassembling large-sized or high-definition displays with small LED panel pitches, particularly in indoor and ultra-high definition applications, where traditional fixing methods like screws are not suitable and may lead to product defects or complex installation processes.
Innovation Solution
A display module utilizing a coupling device with magnetic first and second coupling members, allowing LED panels to be easily mounted and removed using magnetic forces, along with an auxiliary tool to magnetize these members for locking and unlocking, facilitating quick assembly and disassembly without damaging small-sized LEDs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional screw fixing methods are used to mount LED panels on the cabinet, then the LED panels can be securely fixed, but the assembly and disassembly processes become complex and time-consuming
Solution Approach 1:
The patent replaces the traditional mechanical screw fixing system with a magnetic coupling system. The coupling device uses magnetic attraction forces between magnetic members on the LED panel and cabinet to achieve secure mounting without mechanical fasteners. This substitution dramatically simplifies the assembly and disassembly processes while reducing the complexity of the fixing mechanism.
Solution Approach 2:
The patent changes the fundamental parameter of the fixing mechanism from mechanical (screws, bolts) to magnetic (magnetic field strength, attraction force). By adjusting magnetic field parameters and the strength of magnetic members, the system achieves both strong holding force during operation and easy release when needed, resolving the contradiction between secure fixation and ease of assembly/disassembly.
2Manufacturing precision
If LED panels are made small-sized for high definition displays, then the display quality improves, but the panels become difficult to handle and install
Solution Approach 1:
The patent divides the large high-definition display into multiple small LED panels that can be independently handled and installed. Each small panel maintains high definition quality while being manageable in size. The magnetic coupling device further segments the installation process into simple steps of approaching, coupling, and locking, making it easy to install even small precision panels.
Solution Approach 2:
The magnetic coupling device acts as an intermediary mechanism between the small LED panels and the cabinet. It provides a gentle yet secure coupling method that doesn't require direct manual handling of the fragile small panels during installation, thus protecting them while maintaining ease of installation.
3Reliability
If the coupling mechanism is made secure and reliable, then the LED panels remain firmly mounted during operation, but the disassembly process becomes difficult and time-consuming
Solution Approach 1:
The magnetic coupling system operates in periodic cycles: strong magnetic attraction during operation provides reliable mounting, and rapid release when an external force or tool is applied enables quick disassembly. This periodic switching between strong holding and easy release states resolves the contradiction between firm mounting and fast assembly/disassembly.
Solution Approach 2:
The magnetic coupling device provides self-aligning and self-locking functionality. When LED panels are brought close to the cabinet, the magnetic members automatically attract and couple, and the locking portions engage without requiring manual intervention. This self-service mechanism reduces both the time and complexity of assembly while maintaining reliable mounting during operation.
