Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the volume meter is installed in a vertical installation position, then the installation flexibility is improved, but the measurement precision deteriorates due to unfavorable bearing running position
Solution Approach 1:
The inclination sensor determines the installation position beforehand, allowing the arithmetic unit to pre-adjust measurement parameters and calibration data before actual volume measurement begins, ensuring accurate measurements regardless of installation orientation
Solution Approach 2:
The system changes measurement parameters based on detected installation position. The arithmetic unit adjusts calibration factors, gravity compensation values, and sensor sensitivity parameters according to the inclination angle, transforming the meter's performance characteristics to match the installation conditions
2Device complexity
If conventional volume meters are used without position determination, then the device complexity is reduced, but the ability to optimize measurement results deteriorates
Solution Approach 1:
The inclination sensor continuously provides feedback about the installation position to the arithmetic unit, which automatically adjusts measurement parameters and calibration data in real-time, creating a closed-loop system that maintains measurement precision without requiring complex manual intervention
Solution Approach 2:
The volume meter performs self-calibration and self-optimization by automatically detecting its installation position and adjusting its own measurement parameters through the arithmetic unit, eliminating the need for external calibration equipment or complex manual setup procedures
