Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electromagnetic leakage prevention device uses a rigid structure to maintain electromagnetic shielding, then the shielding effectiveness is improved, but the device may scratch the outer surface of hard disk modules during plugging and unplugging
Solution Approach 1:
The device is divided into a rigid frame structure and separate buffer members that can independently deform. The frame maintains the shielding cavity shape while the buffer members absorb contact forces, preventing surface scratching while preserving electromagnetic shielding effectiveness.
Solution Approach 2:
Buffer members are pre-installed at the connecting portions where contact with hard disk modules occurs. These buffer members deform beforehand under contact force, cushioning the impact and preventing direct contact between the rigid frame and the module surface, thus avoiding scratches.
2Object-affected harmful factors
If the device structure is made complex to prevent scratching, then the protection of components is improved, but the device complexity increases
Solution Approach 1:
The buffer members are integrated directly into the frame structure at the connecting portions, merging the protection function into the existing shielding device. This eliminates the need for separate protection components, reducing overall device complexity while maintaining scratching prevention capability.
Solution Approach 2:
The buffer members are placed only at specific connecting portions where contact with hard disk modules occurs, rather than covering the entire device. This localized approach provides protection where needed while minimizing additional complexity and material usage.

AI summary
An electromagnetic leakage prevention device includes a bottom surface, first side walls, second side walls, a first connecting portion, and a second connecting portion. The first side walls are coupled to a side of the bottom surface. The second side walls are coupled to a side of the bottom surface opposite the first side walls. The first connecting portion is coupled to ends of the first side walls away from the bottom surface. The second connecting portion is coupled to ends of the second side walls away from the bottom surface. A distance between the first side walls and the second side walls increases along a direction away from the bottom surface.
