Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different shielding assemblies are designed for different shielding efficiency values, then each detection system can achieve optimal shielding performance, but the unit price cannot be reduced due to limited production series
Solution Approach 1:
The patent applies universality by designing a single standardized shielding assembly that can serve multiple detection systems with different shielding requirements. The key is making the electrical connection device adjustable, allowing one assembly to provide different shielding efficiency levels (EB1, EB2, EB3) depending on the resistance value set. This eliminates the need to produce multiple specialized assemblies for different applications, thereby reducing manufacturing costs while maintaining optimal performance across diverse systems.
Solution Approach 2:
The patent implements dynamics by enabling the shielding assembly to adapt its shielding efficiency dynamically through adjustable resistance values in the electrical connection device. The assembly can be configured for different shielding levels (first, second, third efficiency values) based on operational requirements. This dynamic adaptability allows a single assembly design to replace multiple fixed-configuratio n assemblies, improving manufacturing economy while maintaining system-specific optimization.
2Object-affected harmful factors
If the shielding assembly is made highly opaque to microwave radiation, then shielding efficiency against jamming radiation is improved, but transparency to microwave radiation for detection sensors is reduced
Solution Approach 1:
The patent resolves this contradiction through dynamics by making the shielding assembly's microwave radiation transparency adjustable via the resistance value of the electrical connection device. When jamming radiation is present, the resistance can be increased to enhance shielding efficiency. When detection is the priority, the resistance is reduced to improve microwave transparency. This dynamic adjustment allows the same assembly to adapt to different operational scenarios, resolving the trade-off between shielding and detection capabilities.
Solution Approach 2:
The patent applies parameter changes by modifying the electrical resistance parameter of the connection device to control the shielding assembly's electromagnetic properties. By varying the resistance value, the assembly's shielding efficiency against jamming radiation can be adjusted without changing its physical structure or optical transparency characteristics. This parameter-based control enables flexible adaptation to different threat levels while maintaining detection capability when needed.
3Ease of manufacture
If a fixed shielding efficiency is used, then manufacturing is simplified, but the assembly cannot adapt to varying microwave radiation intensities during operation
Solution Approach 1:
The patent implements dynamics by incorporating an adjustable resistance mechanism in the electrical connection device, allowing the shielding assembly to adapt its performance to varying microwave radiation intensities during operation. The resistance can be modified based on detected radiation levels, enabling the assembly to optimize shielding efficiency in real-time without requiring multiple different assembly designs. This maintains manufacturing simplicity while adding operational flexibility.

AI summary
An optically transparent electromagnetic shield assembly comprising an electrical connection device with variable electrical resistance. The electrical connection device electrically connects a conductive two-dimensional structure, which covers a transparent substrate, to a shell portion which is electrically conductive.
