Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple detection devices are combined to measure multiphase fluid flow, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality by enabling a single ultrasonic flowmeter to perform multiple measurement functions. The flowmeter measures not only the flow quantity of the multiphase fluid but also detects the presence and quantity of gas bubbles and solid particles simultaneously. This is achieved by processing ultrasonic signals to extract multiple parameters (flow velocity, gas bubble presence, solid particle presence) from the same detection system, eliminating the need for separate detection devices for each parameter.
Solution Approach 2:
The patent merges multiple detection functions into a single integrated ultrasonic flowmeter device. Instead of combining separate flowmeters, gas bubble detectors, and solid particle detectors, the invention integrates all these functions into one device that uses ultrasonic transducers to detect and measure all parameters simultaneously, thereby reducing device complexity while maintaining measurement precision.
