Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a calibrated clamp-on ultrasonic measurement device is arranged in series with a flowmeter for in-line checking, then measurement accuracy can be verified, but the verification process becomes time-consuming due to data transmission and external evaluation
Solution Approach 1:
The measurement device performs self-verification by comparing its own measured values against stored specification values internally, eliminating the need for external evaluation devices and data transmission processes. The electronic measuring/operating circuit directly outputs verification results, enabling the device to verify itself autonomously and rapidly.
Solution Approach 2:
The verification function is extracted as a separate, dedicated mode within the electronic measuring/operating circuit, distinct from normal measurement operations. This allows verification to be performed independently with optimized processing, comparing measured values against pre-stored specification values without requiring external evaluation systems.
2Reliability
If measured values are transmitted to an external evaluation device for analysis, then comprehensive verification can be performed, but the process complexity and time consumption increase
Solution Approach 1:
The electronic measuring/operating circuit is designed to perform both normal measurement functions and self-verification functions using the same hardware components. The circuit stores specification values in its memory and performs comparisons internally, making the measurement device itself a universal system that can both measure and verify without requiring separate external evaluation equipment.
Solution Approach 2:
The device performs self-verification autonomously by internally comparing its measured values against stored specification values. This self-service capability eliminates the need for external evaluation devices, reducing system complexity while maintaining verification reliability through direct internal processing and immediate result output.
