Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring rock breaking dynamics are limited in accurately capturing stress wave parameters due to interference from magnetizing coils used simultaneously for measurement, which affects the reliability of stress wave data during rock breaking operations.
Innovation Solution
A method and arrangement where components of the rock breaking system are subjected to persistent magnetization using permanent magnets or magnetization means, allowing for the measurement of rock breaking dynamics based on changes in magnetic properties without simultaneous magnetization during measurement, thereby reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If magnetizing coils are used simultaneously for measurement during rock breaking, then measurement capability is provided, but measurement precision deteriorates due to interference from the magnetizing coils
Solution Approach 1:
The patent extracts the magnetizing function from the measurement process by using permanently magnetized components instead of active magnetizing coils during measurement. The component is magnetized beforehand and then measured without simultaneous magnetization, removing the interference source from the measurement environment.
Solution Approach 2:
The component is magnetized in advance before the measurement process begins. This preliminary magnetization allows the measurement to proceed without requiring active magnetizing coils, thereby eliminating the interference that would occur if magnetization and measurement happened simultaneously.
2Measurement precision
If permanent magnets are used to provide persistent magnetization, then measurement precision improves by eliminating interference, but device complexity increases due to arrangement of permanent magnets or magnetization means
Solution Approach 1:
The patent merges the magnetization function into the component itself by permanently magnetizing it, rather than requiring separate magnetizing coils and power supplies. This integration eliminates additional device components while maintaining the required magnetic field for measurement.
Solution Approach 2:
The component serves its own magnetization needs by being permanently magnetized, eliminating the requirement for external magnetizing equipment during operation. The component self-maintains its magnetic state without requiring continuous external energy input or control systems.
