Resonator Frame Layout for Frequency Trimming Debris Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insulation failures occur in resonators due to scattering objects from the vibration arm when the resonant frequency is adjusted, particularly when the adjustment film scatters from the vibration arm and enters gaps within the resonator.
Innovation Solution
The resonance device incorporates a lower lid with a recessed portion and a frame around the vibration arm, where the facing portion of the frame is positioned outside a specific line connecting the vibration arm tip to the recessed portion, limiting the scattering range of fragments and reducing the likelihood of insulation failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the vibration arm is excessively excited to scrape the adjustment film, then the resonant frequency can be adjusted, but scattering objects may enter the gap between the upper lid and resonator causing insulation failure
Solution Approach 1:
A frame structure is introduced as an intermediary component between the vibration arm and the upper lid. This frame includes a facing portion that acts as a physical barrier, preventing scattering objects from reaching the gap between the upper lid and resonator while allowing the vibration arm to perform its scraping function for resonant frequency adjustment.
Solution Approach 2:
The space around the vibration arm is segmented by introducing a frame structure with a facing portion. This segmentation creates a dedicated barrier zone that separates the scattering object generation area from the insulation-critical gap, allowing the scraping operation to proceed without compromising insulation performance.
2Manufacturing precision
If the vibration arm is excessively excited to scrape the adjustment film, then the resonant frequency can be adjusted, but scattering objects may enter the inner wall area causing insulation failure
Solution Approach 1:
The frame with its facing portion serves as an intermediary barrier that intercepts scattering objects before they can reach the inner wall area. This mediator structure allows the vibration arm to perform frequency adjustment through excessive excitation while preventing the harmful scattering objects from compromising insulation performance near the inner wall.
3Volume of moving object
If the facing portion of the frame is positioned inside the straight line connecting the vibration arm tip to the recessed portion, then the structure is compact, but scattering objects can still reach the upper lid gap
Solution Approach 1:
The facing portion of the frame is positioned in the outer-side portion relative to a specific straight line, creating a spatial arrangement in a different dimensional orientation. This positional configuration in another dimension effectively blocks the path of scattering objects toward the upper lid gap while maintaining compact overall structure.
