Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a stroke card or measuring system is attached to a vibrating machine, then vibration behavior can be measured and analyzed, but meticulous alignment must be paid to ensure accurate results
Solution Approach 1:
The sensor automatically determines the horizontal reference plane and calculates vibration parameters independently of mounting orientation, making the system self-aligning and eliminating the need for meticulous manual alignment by the operator
Solution Approach 2:
The system transforms vibration data from sensor coordinates to reference plane coordinates through automatic calculation of the horizontal reference plane, enabling accurate vibration parameter determination regardless of the sensor's mounting orientation
2Loss of information
If traditional vibration analysis methods are used, then some vibration parameters can be determined, but not all parameters characterizing the vibration can be fully determined and displayed
Solution Approach 1:
The system automatically determines the horizontal reference plane by analyzing vibration data in three-dimensional space, adding the dimension of automatic orientation reference to enable complete vibration parameter determination without proportionally increasing system complexity
3Measurement precision
If a sensor is attached to a vibrating machine to measure vibrations, then vibration data can be collected, but the attachment orientation affects the evaluation of vibration data
Solution Approach 1:
The system automatically transforms vibration measurements into parameters referenced to the horizontal reference plane through coordinate transformation calculations, enabling accurate vibration analysis regardless of the sensor's mounting orientation and providing mounting orientation flexibility
