Magnetic Separating Structure for LED Display Light Board Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for disassembling LED display screens are cumbersome, labor-intensive, and often result in damage to the display light board, especially in small-pitch products where screw placement is limited, and require high professional skills, posing safety hazards due to the risk of motor burnout during tight assembly disassembly.
Innovation Solution
A display screen component with a ferromagnetic body-based separating structure that uses an external magnetic force to separate the display light board from the module rear shell, facilitated by a rotating rod and pivot shafts, allowing for easy disassembly without manual prying or customized motor control, and includes a return structure for stabilization and buffering to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screw disassembling manner is used to separate the module rear shell and display light board, then the connection can be securely fastened, but the disassembly process becomes cumbersome and inefficient
Solution Approach 1:
The patent replaces the traditional mechanical screw fastening system with a magnetic field-based fastening system. The magnetic fastening structure uses magnetic attraction forces to hold the display light board to the module rear shell, eliminating the need for screws during both assembly and disassembly operations. This substitution transforms a complex mechanical disassembly process into a simple one-step magnetic release operation.
2Productivity
If manual prying is used to remove the display light board, then no additional components are needed, but the process is time-consuming, labor-consuming, and causes damage to the display light board
Solution Approach 1:
The patent replaces manual mechanical prying with a magnetic field-based separation mechanism. The magnetic fastening structure allows the display light board to be separated from the module rear shell through magnetic force reversal or reduction, eliminating the need for manual prying tools and operations. This prevents physical damage to the display light board while significantly improving disassembly efficiency.
3Extent of automation
If a small internal motor is used to push out the display light board, then automated separation is achieved, but customized motor control is required, increasing workload and safety risks
Solution Approach 1:
The patent replaces the motor-based automated separation system with a magnetic field-based system. Instead of using a small internal motor that requires customized control circuits and poses safety risks from motor burnout, the invention uses magnetic attraction and repulsion forces that can be controlled through simple magnetic field activation, achieving automation without complex motor control systems.
4Strength
If the assembly is made tight for secure fastening, then the connection strength is improved, but the motor is easily burned during disassembly
Solution Approach 1:
The patent eliminates the motor component entirely by using magnetic field forces for both fastening and separation. The magnetic fastening structure provides strong connection strength through magnetic attraction while avoiding motor burnout issues by using magnetic field reversal or reduction for separation. This substitution removes the reliability concern associated with motor operation under tight assembly conditions.
