Solution Overview

Problem

Display apparatuses, particularly those using OLED panels, face challenges in easy disassembly for inspection or repair without causing damage, due to the complexity of separating them from installation surfaces and the risk of damage during disassembly.

Innovation Solution

The display apparatus incorporates a magnetically detachable LED module assembly and a removable protection cover, allowing for selective disassembly of components without fully separating from the installation surface, facilitating access to internal components like the control board and power cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display apparatus is completely disassembled from the installation surface for inspection or repair, then access to internal components is improved, but the risk of damage to the LED module assembly and surrounding components increases

Engineering Contradiction:
Improveaccess to internal componentsVSAvoidrisk of damage to LED module assembly
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The display apparatus is divided into separable modules: the LED module assembly can be detached from the main body while remaining connected to the installation surface. This segmentation allows inspection and repair of internal components without complete disassembly, reducing damage risk to surrounding LED modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The LED module assembly is extracted as a separate detachable unit from the main display apparatus. The magnetic coupling mechanism allows the LED module assembly to be removed for servicing while the main apparatus remains installed, providing access to control boards and power cables without removing the entire display from the installation surface.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of repair

If the LED module assembly is detached from the main frame for inspection, then access to control board and power cables is improved, but the structural integrity and stability of the display apparatus deteriorates

Engineering Contradiction:
Improveaccess to control boardVSAvoidstructural integrity
Core Design Contradiction:
Ease of repairVSStability of the object's composition

Solution Approach 1:

The magnetic coupling mechanism provides dynamic connectivity - the LED module assembly can be easily attached or detached from the main frame as needed. During normal operation, the magnetic force maintains structural integrity; during repair, the assembly can be detached to access control boards and power cables without permanent structural compromise.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Traditional mechanical fastening systems (screws, clips) are replaced with magnetic coupling. This substitution enables easier detachment and reattachment of the LED module assembly while maintaining stable structural connection during operation, facilitating repair access without compromising overall stability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If a protective structure is added around LED module assemblies to prevent damage during disassembly, then the protection level increases, but the device complexity increases

Engineering Contradiction:
Improveprotection of LED module assembliesVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The magnetic coupling mechanism serves multiple functions: it provides structural connection during normal operation, enables easy detachment for repair, and acts as a protective feature by allowing controlled separation without damage. This multi-functionality reduces the need for additional specialized protective structures, maintaining simplicity while enhancing protection.

Inventive Principle:
Principle #6Universality (Multi-functionality)
