Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional resonator designs are used, then the resonator can maintain stable resonance characteristics, but the resonator size becomes large and cannot be integrated into compact integral-type modules
Solution Approach 1:
The resonator is segmented into multiple functional layers: conductor plates forming the outer shell, dielectric material filling the interior, and metamaterial patches arranged on the inner surface. This segmentation allows each component to contribute specifically to size reduction while maintaining overall resonance stability.
Solution Approach 2:
The resonator employs composite material construction combining conductor plates, dielectric material, and metamaterial patches. This composite structure enables the resonator to achieve both compact size and stable resonance characteristics by leveraging the complementary properties of each material type.
2Volume of moving object
If the resonator size is reduced to fit integral-type modules, then integration becomes possible, but the resonance frequency and performance may be compromised
Solution Approach 1:
The resonator utilizes parameter changes in the metamaterial patches, specifically varying the area of the patches to control and adjust the resonance frequency. This allows precise frequency tuning within the compact resonator structure, maintaining resonance accuracy despite the reduced size.
Solution Approach 2:
The invention transitions from conventional three-dimensional resonator structures to a two-dimensional metamaterial patch configuration on the inner surface of the resonator. This dimensional change enables size reduction while preserving resonance characteristics through the engineered electromagnetic properties of the metamaterial patches.
