Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a capacitor is soldered onto a printed circuit board to filter DC components, then DC isolation is achieved, but the manufacturing process becomes complex and costly
Solution Approach 1:
The patent replaces the mechanical soldering process with a friction-based mechanical insertion system. The dielectric coupling sleeve is inserted into the conductor cavity and held in place by friction forces, eliminating the need for soldering while achieving the same electrical connection function.
Solution Approach 2:
The dielectric coupling sleeve acts as an intermediary component between the first electrical conductor and the second electrical conductor. It provides both mechanical support and electrical isolation, while the receiving space extends into the second sleeve section to increase capacitance for effective DC blocking.
2Reliability
If conventional capacitive coupling is used with soldering, then electrical connection is established, but production time and cost increase
Solution Approach 1:
The patent replaces the time-consuming soldering process with a quick friction-based mechanical insertion system. The dielectric coupling sleeve is simply inserted into the conductor cavity where friction forces hold it in place, dramatically reducing assembly time and increasing production efficiency.
Solution Approach 2:
The friction forces between the dielectric coupling sleeve and the conductor cavity automatically secure the connection without requiring additional fastening operations or external tools. The system self-secures upon insertion, eliminating the need for separate mounting steps.
3Reliability
If the receiving space extends into the second sleeve section, then capacitance is increased for better DC blocking, but the structure becomes more complex
Solution Approach 1:
The patent merges the receiving space with the second sleeve section by extending the receiving space at least partially into the second sleeve section. This integration increases the capacitance of the capacitor formed by the electrical conductors and dielectric coupling sleeve while maintaining a unified, manufacturable structure.
Solution Approach 2:
The receiving space is nested within the dielectric coupling sleeve structure, with the receiving space extending into the second sleeve section. This nested arrangement maximizes the capacitive coupling volume within the available space without requiring separate components.
