Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a seizure screw is used to compress and contact the pin connector, then the connection is mechanically secure, but the inherent capacitance causes signal attenuation and reflection at high frequencies
Solution Approach 1:
The patent replaces the traditional mechanical seizure screw compression system with a conductive adhesive bonding system. The conductive adhesive (epoxy with metal particles) provides both mechanical attachment and electrical conduction, eliminating the capacitance issues associated with mechanical compression contacts while maintaining secure connection.
Solution Approach 2:
The patent changes the fundamental parameter of contact mechanism from mechanical compression to chemical-adhesive bonding with conductive properties. This parameter change eliminates the parasitic capacitance inherent in mechanical screw compression while maintaining mechanical security through the adhesive's bonding strength.
2Reliability
If separate RF connectors are used for aerial and underground installations, then each installation type has optimized connection, but the device complexity and cost increase
Solution Approach 1:
The patent designs a universal receptacle with a flexible connection plate that can accommodate both aerial (horizontal) and underground (vertical) installations. The flexible plate adapts its orientation to match the cable approach direction, providing optimized contact for both installation types with a single connector design, thereby reducing device complexity and cost.
