Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the same device under test is used for calibration in both test equipments, then the calibration process can be performed, but the device experiences repetitive high water-pressure which causes variation in leakage performance and reduces calibration accuracy
Solution Approach 1:
The calibration system is divided into two separate parts: a calibration device that generates controlled water leakage and a device under test being calibrated. This segmentation allows the calibration device to remain stable while the DUT is adjusted, resolving the contradiction by eliminating the need for the DUT to withstand repetitive high pressure during calibration.
Solution Approach 2:
A dedicated calibration device acts as an intermediary standard between multiple devices under test. This intermediary provides a stable reference with controllable leakage characteristics, allowing calibration without subjecting the same test device to damaging repetitive high water-pressure cycles.
2Adaptability or versatility
If test equipments from different vendors are used, then more testing options are available, but the testing criteria and results differ due to varying device performance
Solution Approach 1:
The calibration device is designed as a universal standard that can calibrate multiple different test equipments from various vendors. By providing a common reference with controllable water leakage characteristics, it enables consistent calibration across different testing systems, resolving the contradiction between versatility and result consistency.
Solution Approach 2:
The calibration device allows adjustment of water leakage parameters (such as flow rate, pressure, or leakage amount) to match different testing requirements. This parameter controllability enables the same calibration standard to adapt to various test equipments while maintaining measurement consistency across all platforms.
3Measurement precision
If a complex calibration method is used to improve accuracy, then calibration precision may improve, but the calibration process becomes more complicated and costly
Solution Approach 1:
Instead of using complex calibration procedures, the invention creates a simplified copy or replica of the water leakage condition through a dedicated calibration device. This device replicates the essential calibration function using a simple structure with controllable leakage, avoiding the need for complex procedures while maintaining accuracy.
Solution Approach 2:
The calibration device uses simple, inexpensive components such as plates with adjustable gaps or basic flow control elements. These simple structures can be easily manufactured and replaced if needed, providing accurate calibration without the complexity and cost of sophisticated calibration systems.
