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 patent combines the shielding flap and ground contact into a single integrally formed conductive element on the plug head. This merging of functions reduces the number of separate components while maintaining effective electromagnetic shielding and grounding capabilities, thereby reducing device complexity without compromising shielding performance
Solution Approach 2:
The conductive element on the plug head serves multiple functions simultaneously: it acts as a shielding flap to block electromagnetic fields, a ground contact to establish electrical ground connection, and a structural component of the plug assembly. This multi-functionality eliminates the need for separate shielding and grounding components, reducing overall device complexity
2Object-affected harmful factors
If complex electromagnetic shielding solutions are used in known electric plugs, then electromagnetic shielding is improved, but manufacturing cost increases
Solution Approach 1:
By integrating the shielding and grounding functions into a single conductive element, the patent reduces the number of parts that need to be manufactured and assembled. This simplification lowers manufacturing costs while maintaining effective electromagnetic shielding
Solution Approach 2:
The patent employs a simple conductive coating or material on the plug head that provides effective electromagnetic shielding without requiring complex multi-layer structures or expensive specialized materials, thereby reducing manufacturing cost
3Ease of operation
If gaps exist between the electric plug and vehicle camera housing, then assembly is easier, but electromagnetic field emission increases
Solution Approach 1:
The shielding flap on the plug head automatically contacts the vehicle camera housing upon insertion, creating an effective electromagnetic shield without requiring precise alignment or additional assembly steps. The design self-adjusts to eliminate gaps, preventing electromagnetic field emission while maintaining ease of assembly
Solution Approach 2:
The shielding flap is designed as a flexible or resilient component that can adapt to slight variations in assembly position, ensuring continuous contact with the housing to block electromagnetic fields while accommodating tolerances that simplify assembly
4Reliability
If the shielding flap is made resilient, then contact reliability with housing is improved, but manufacturing complexity increases
Solution Approach 1:
The resilient shielding flap is integrally formed with the ground contact element, combining two functions into one component. This reduces the number of parts while maintaining reliable contact through the resilient property, thereby improving reliability without proportionally increasing device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces electromagnetic field emission through the plug's design, ensuring improved shielding and secure grounding of the vehicle camera's housing upon connection.
Implementation Method 1
An outwardly projecting shielding flap of the electric plug is configured to be integrally formed with the cover collar. The shielding flap is connected with an electrically conductive connecting element, which is connected with the cover collar and the mass contact. By such a design of the electric plug an improved electromagnetic shielding is facilitated.
