Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plate electrode overlaps with multiple strip line resonators to capacitively couple them, then the transmission characteristics can be adjusted, but the design becomes complicated and it is difficult to adjust coupling capacitance independently
Solution Approach 1:
The invention divides the coupling function into separate segments by providing individual coupling conductors for each resonator pair. Instead of one plate electrode handling multiple coupling relationships, separate coupling conductors are used for each resonator, allowing independent adjustment of each coupling capacitance without affecting others.
Solution Approach 2:
The invention extracts the coupling function from the plate electrode by introducing dedicated coupling conductors. The plate electrode's primary function is separated from the coupling function, which is now performed by specialized coupling conductors that can be independently designed and adjusted for each resonator pair.
2Reliability
If a plate electrode is used to capacitively couple resonators, then transmission characteristics can be optimized, but the coupling capacitance between adjacent resonators cannot be adjusted independently
Solution Approach 1:
The coupling function is segmented into independent units with dedicated coupling conductors for each resonator pair. This segmentation allows each coupling capacitance to be adjusted independently while maintaining reliable transmission characteristics through optimized individual coupling paths.
Solution Approach 2:
Each coupling conductor is designed with local quality optimized for its specific resonator pair. The shape, size, and position of each coupling conductor can be independently tailored to achieve the desired coupling capacitance for that specific location without affecting other coupling relationships.
3Manufacturing precision
If the shape of the plate electrode is designed to adjust coupling capacitance, then transmission characteristics can be optimized, but the design process becomes complicated
Solution Approach 1:
The design process is simplified by segmenting the coupling function into independent conductors. Each coupling conductor's shape can be independently optimized for its specific function without requiring complex overall plate electrode design, making the manufacturing precision achievable through simpler, more straightforward design processes.
Solution Approach 2:
The coupling function is extracted from the plate electrode design, allowing the plate electrode to maintain a simple, standardized shape while dedicated coupling conductors handle the capacitance adjustment. This extraction simplifies the overall design process while maintaining the ability to achieve precise coupling capacitance values.
