Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the measuring device is calibrated with water before delivery, then the calibration is simple and quick, but the measurement deviation increases when filling media different from water
Solution Approach 1:
The system dynamically adjusts operating parameters of the filling point measuring device based on the specific medium being filled. The computing unit receives medium information, determines optimized parameters, and adjusts the measuring device to compensate for deviations caused by different medium properties, thereby maintaining measurement precision across various media while keeping calibration simple
Solution Approach 2:
The system uses feedback from the control measuring device to continuously monitor and adjust the filling point measuring device performance. By comparing control measurements with filling point measurements, the system identifies deviations and applies corrections, ensuring accurate measurements for different media without complex recalibration
2Reliability
If multiple filling routines are performed to determine and optimize repeatability, then the repeatability of the filling point measuring device is improved, but the filling time increases
Solution Approach 1:
The system performs repeatability optimization in advance during setup or maintenance phases, determining optimal parameters before actual filling operations begin. This preliminary optimization ensures high repeatability during production while minimizing time loss during actual filling, as the parameter optimization is completed beforehand
Solution Approach 2:
The system implements periodic repeatability checks and optimizations at scheduled intervals rather than continuously. This approach maintains high repeatability through regular optimization cycles while avoiding time loss during normal filling operations, balancing reliability with productivity
