Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate elastic connecting elements are used for outer conductor connections, then reliable electromagnetic shielding is achieved, but manufacturing and assembly complexity increases
Solution Approach 1:
The patent integrates the outer conductor connecting element directly into the contact carrier, merging previously separate components (elastic connecting element and ground contact) into a single integrated structure. This reduces the number of parts and simplifies assembly while maintaining reliable electromagnetic shielding through the integrated elastic contact sections.
Solution Approach 2:
The contact carrier is designed to serve multiple functions: it holds the signal contacts and simultaneously provides the outer conductor connection through integrated elastic connecting sections. This multi-functionality eliminates the need for separate elastic connecting elements, reducing assembly complexity while ensuring reliable shielding.
2Reliability
If complex outer conductor connections are used, then reliable electromagnetic shielding is achieved, but manufacturing cost increases
Solution Approach 1:
By combining the outer conductor connecting element with the contact carrier into a single integrated component, the patent reduces the total part count and simplifies manufacturing processes. This integration maintains reliable electromagnetic shielding while lowering manufacturing costs through reduced material usage and simplified production.
Solution Approach 2:
The patent employs elastic sections with specific lateral elasticity to achieve reliable outer conductor connections. By optimizing the elastic properties and geometric parameters of these integrated sections, the design achieves effective electromagnetic shielding with simpler, more cost-effective manufacturing compared to traditional complex rigid connection structures.
3Stability of the object's composition
If rigid outer conductor connections are used, then structural stability is achieved, but tolerance compensation and vibration resistance decrease
Solution Approach 1:
The patent incorporates elastic sections within the integrated contact carrier that provide lateral elasticity. These dynamic elements allow the structure to adapt to tolerances and absorb vibrations, maintaining reliable outer conductor connections under varying mechanical conditions while preserving overall structural stability.
Solution Approach 2:
By designing the integrated outer conductor connecting element with specific elastic properties, the patent enables the structure to dynamically adjust to mechanical tolerances and vibrations. The elastic parameters are optimized to provide both structural stability and vibration resistance, overcoming the limitations of purely rigid connections.
