Engineering Contradictions & Design Principles
Engineering 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
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
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
2Manufacturing precision
If a conventional coupling process is used for large display panels, then the assembly can be completed, but assembly inaccuracies increase
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
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
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
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)

AI summary
Disclosed herein is a display apparatus. The display apparatus includes a display panel, a display chassis configured to support the display panel, and a cover provided on a rear side of the display chassis. The cover includes a cover body configured to cover a rear surface of the display chassis, and a plurality of magnets disposed on the cover body and configured to generate an attractive force such that the cover body is attached to the rear surface of the display chassis. The cover is configured to be coupled and fixed to at least a part of peripheries of the display chassis and the cover body. With this configuration, assembly efficiency of the display apparatus may be improved.
