Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a conventional coupling process is used for large display panels, then the assembly can be completed, but the assembly process becomes complex and production efficiency decreases

Engineering Contradiction:
Improveproduction efficiencyVSAvoidassembly process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical coupling processes with a magnetic coupling system. Magnets are embedded in the cover and chassis to create attractive forces that automatically align and secure the cover to the display chassis, eliminating the need for complex mechanical fasteners and reducing assembly steps

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

Solution Approach 2:

The patent changes the coupling mechanism from mechanical interlocking to magnetic attraction by varying the physical parameter of force application. The magnetic field strength and distribution are optimized to provide sufficient holding force while enabling easy assembly and disassembly, thus improving production efficiency

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If a conventional coupling process is used for large display panels, then the assembly can be completed, but assembly inaccuracies increase

Engineering Contradiction:
Improveassembly accuracyVSAvoidassembly process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The magnetic coupling system provides automatic alignment through the attractive force between magnets in the cover and chassis. This self-aligning mechanism ensures precise positioning without requiring complex mechanical guides or manual adjustment, thereby improving assembly accuracy while maintaining simplicity

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

3Ease of manufacture

If magnets are used to couple the cover to the display chassis, then the assembly process is simplified, but the coupling durability must be ensured

Engineering Contradiction:
Improveassembly simplicityVSAvoidcoupling durability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent strategically positions multiple magnets at specific locations on the cover and corresponding positions on the chassis to create localized zones of strong magnetic attraction. This ensures that the magnetic force is concentrated at critical coupling points, providing durable attachment while keeping the overall assembly process simple

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent combines multiple magnetic coupling points into a unified magnetic assembly system. The collective attractive force of multiple magnets distributed across the cover-chassis interface provides both simplified assembly (through uniform attraction) and enhanced durability (through distributed holding force)

Inventive Principle:
Principle #5Merging (Combining)
