Solution Overview

Problem

Existing multi resonator systems face challenges in improving both time and frequency resolution due to computational load and crosstalk effects caused by coupling between resonators with different center frequencies.

Innovation Solution

A multi resonator system design where each resonator has a unique center frequency, with resonators arranged in a flat plane without overlapping, and adjacent resonators having the same center frequency to reduce crosstalk and enhance resonance displacement and output signal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple resonators with different center frequencies are arranged adjacently to cover broader frequency range, then frequency resolution is improved, but crosstalk effect increases due to coupling between adjacent different resonators

Engineering Contradiction:
Improvefrequency resolutionVSAvoidcrosstalk effect
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent divides the resonator system into multiple independent resonator units, each with its own fixer, driver, and sensor. By segmenting the system into separately fixed resonators rather than a single coupled structure, crosstalk between adjacent resonators is reduced while maintaining the ability to detect multiple frequency components

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each resonator is designed with localized properties including specific center frequencies, quality factors, and sensitivity characteristics. The resonators have different center frequencies optimized for specific frequency bands, allowing each to operate independently with minimal interference from adjacent resonators

Inventive Principle:
Principle #3Local quality

2Measurement precision

If resonators are made more sensitive to detect weak signals, then detection precision is improved, but resonance displacement at center frequency decreases

Engineering Contradiction:
Improvedetection precisionVSAvoidresonance displacement
Core Design Contradiction:
Measurement precisionVSManufacturing precision

Solution Approach 1:

Multiple resonators with the same center frequency are grouped within each multi-resonator unit. By combining the output signals from multiple resonators with identical center frequencies, the system achieves enhanced sensitivity and detection precision while maintaining adequate resonance displacement through the collective response

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If Fourier transform is used to acquire frequency domain information, then frequency analysis is achieved, but computational load increases and time resolution deteriorates

Engineering Contradiction:
Improvefrequency information acquisitionVSAvoidtime resolution
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the computational Fourier transform approach with a mechanical resonance-based frequency analysis system. Each resonator naturally responds to its resonant frequency, providing direct frequency domain information through physical resonance rather than mathematical transformation, thereby reducing computational load and improving time resolution

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
