Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If complex electromagnetic shielding solutions are used in known electric plugs, then electromagnetic shielding is improved, but device complexity and cost increase
Solution Approach 1:
The shielding function is segmented into multiple components: a shielding collar surrounding the carrier block, shielding flaps extending from the collar, and a grounding element. Each segment performs a specific shielding function, allowing the system to achieve comprehensive electromagnetic shielding while maintaining modular simplicity and reducing overall device complexity.
Solution Approach 2:
The shielding solution transitions from two-dimensional planar shielding to three-dimensional volumetric shielding by adding the shielding collar that surrounds the carrier block in multiple directions. This dimensional expansion provides comprehensive electromagnetic shielding coverage without requiring complex internal structures within each shielding plane.
2Ease of operation
If gaps exist between the electric plug and vehicle camera housing, then ease of assembly is improved, but electromagnetic field emission increases
Solution Approach 1:
The shielding flaps are designed with flexible or resilient characteristics, allowing them to dynamically adapt and make contact with the vehicle camera housing upon assembly. This dynamic behavior ensures electromagnetic shielding is effective while maintaining ease of assembly, as the flaps automatically seal gaps without requiring precise alignment or forcing components together.
Solution Approach 2:
The shielding collar acts as an intermediary component between the rigid carrier block and the vehicle camera housing. It provides a transition zone that maintains the shielding function while accommodating manufacturing tolerances and assembly variations, thereby preventing electromagnetic field emission without compromising assembly ease.
3Device complexity
If the housing of the vehicle camera is not grounded, then device complexity is reduced, but safety and reliability decrease
Solution Approach 1:
The grounding element is designed to automatically establish an electrical connection with the vehicle camera housing upon assembly through direct contact or conductive proximity. This self-service grounding mechanism ensures reliable grounding without requiring additional grounding wires, connectors, or complex grounding circuits, thereby maintaining simplicity while achieving high grounding reliability.
Solution Approach 2:
The grounding function is merged with the existing shielding structure by integrating the grounding element into the shielding collar or carrier block. This combination achieves both electromagnetic shielding and grounding functions through a unified structure, reducing overall device complexity while ensuring reliable grounding for safety.
