Magnetic Snap-Fit LED Display Module for Lightweight Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED display panels face challenges in disassembly and assembly due to their fixed structure, making maintenance inconvenient, and adding magnets for magnetic attraction increases weight, contradicting the need for ultra-light designs.
Innovation Solution
The LED display module employs a connecting member made of magnetic material with a snap-fitting part for detachable connection, using magnets on the cabinet for assembly, eliminating the need for additional magnetic members and reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If iron sheets are arranged in the bottom shell and magnets are arranged in the LED cabinet to achieve magnetic attraction assembly, then the LED display module and cabinet can be easily assembled and disassembled, but the weight of the LED display panel is increased
Solution Approach 1:
The connecting member integrates both the magnetic attraction function and the mechanical connection function. The magnetic component is embedded within the connecting member structure, combining what were previously separate elements (iron sheets in bottom shell, magnets in cabinet) into a single integrated component that achieves both magnetic attraction and structural connection.
Solution Approach 2:
The connecting member serves multiple functions simultaneously: it provides magnetic attraction for easy assembly, acts as a mechanical fastener for secure connection, and eliminates the need for separate iron sheets and magnets. This multi-functional design resolves the contradiction by reducing overall component count and weight while maintaining ease of assembly.
2Ease of repair
If multiple iron sheets and magnets are added to achieve detachable magnetic connection, then the LED display panel becomes easier to maintain, but the device complexity increases
Solution Approach 1:
The connecting member merges the magnetic attraction mechanism with the mechanical connection structure into a single integrated component. This eliminates the need for separate iron sheets in the bottom shell and magnets in the cabinet, reducing the number of parts while maintaining the detachable magnetic connection functionality that facilitates maintenance.
Solution Approach 2:
The magnetic attraction function is extracted from the separate iron sheets and magnets and integrated into the connecting member itself. This extraction consolidates multiple components into one, simplifying the overall structure while preserving the ease of maintenance through detachable connection.
