Solution Overview
Problem
Conventional methods for modifying the resonance properties of ceramic resonators are time-consuming, requiring manual reshaping and complete plating removal, which complicates the reshaping process and is inefficient.

The use of electrically conductive coupling sheets with patterns, such as through holes, between ceramic resonator articles allows for easy tuning of resonance properties by replacing or modifying the coupling sheets, simplifying the process and reducing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual reshaping and complete plating removal are used to modify resonance properties, then the resonance characteristics can be adjusted, but the process becomes time-consuming and complicated
Solution Approach 1:
The resonator is divided into separate functional components: a ceramic resonator body and a removable coupling sheet with conductive patterns. This segmentation allows the coupling sheet to be independently modified or replaced to tune resonance properties without affecting the resonator body, thereby reducing modification time while maintaining adaptability
Solution Approach 2:
A coupling sheet with conductive patterns is introduced as an intermediary element between the ceramic resonator body and external circuitry. This coupling sheet serves as a tunable interface that modifies resonance characteristics through its conductive pattern design, eliminating the need for time-consuming manual reshaping and plating removal of the resonator body itself
2Adaptability or versatility
If manual reshaping and complete plating removal are used to modify resonance properties, then the resonance characteristics can be adjusted, but the process complexity increases
Solution Approach 1:
The resonator system is segmented into a permanent ceramic resonator body and a separate coupling sheet. This segmentation simplifies the overall process by confining all modification activities to the coupling sheet alone, reducing process complexity while preserving full tunability of resonance properties through pattern design variations
Solution Approach 2:
The coupling sheet functions as a disposable or easily replaceable component with conductive patterns. Instead of permanently modifying the expensive resonator body through complex plating removal and reshaping, simple coupling sheets with different patterns can be manufactured and swapped to achieve desired resonance characteristics, thereby reducing both process complexity and time
