Solution Overview
Problem
Infrasonic waves, with frequencies below 20 Hz, are undetectable by typical acoustic detectors and require innovative methods to detect and measure effectively, especially for natural phenomena and man-made activities.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If typical acoustic detectors are used, then the device complexity is low, but the measurement precision for infrasonic waves is insufficient
Solution Approach 1:
The system divides the detection function into two separate components: cylindrical magnets that respond to infrasound waves and a diamagnetic object that remains relatively stationary. This segmentation allows each component to be optimized for its specific function, improving measurement precision while keeping individual components simple
Solution Approach 2:
The diamagnetic object serves as an intermediary between the infrasound waves and the detection system. It interacts with the magnetic field of the cylindrical magnets to amplify the detection signal, enabling precise infrasound detection without requiring complex direct measurement equipment
2Measurement precision
If the object is coupled to the magnets, then the structural stability is high, but the detection sensitivity to relative motion is reduced
Solution Approach 1:
The diamagnetic object acts as a counterweight that is magnetically levitated between the cylindrical magnets. This creates a balanced system where gravitational and magnetic forces counteract each other, maintaining stability while allowing sensitive detection of relative motion caused by infrasound waves
Solution Approach 2:
The system transitions from a static coupled structure to a dynamic levitated configuration. The diamagnetic object is free to move within the magnetic field, creating a dynamic system that is highly sensitive to external infrasound disturbances while maintaining overall structural stability through magnetic confinement
