Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a Coriolis measuring device is used to measure the liquid component property, then the measurement can be performed, but the measurement precision deteriorates due to difficulties in drawing conclusions from measured tube vibrations
Solution Approach 1:
The patent extracts the liquid component from the gas-loaded medium by utilizing gravity-driven flow separation in a specifically designed pipeline geometry. The first section at a shallow angle (less than 20°) allows the liquid to accumulate and separate from the gas phase, enabling the measuring device to detect only the liquid component's properties without interference from gas loading.
Solution Approach 2:
The pipeline is segmented into distinct functional sections: a first section for flow entry and initial separation, a closed end region for liquid accumulation and measurement, and a second section (riser) for gas discharge. This segmentation creates dedicated zones for different functions, ensuring that the measuring device operates in an environment optimized for liquid-only measurement.
2Reliability
If the pipeline is designed with a closed end to separate liquid and gas components, then the measurement reliability improves, but the device complexity increases
Solution Approach 1:
The closed end is designed with a specific inclination angle (between 2° and 15°) that creates a gravity-driven flow path. This inclination ensures that gas does not accumulate in the closed end region by allowing continuous drainage of the liquid component, while the overall structure remains relatively simple without requiring complex active control mechanisms.
Solution Approach 2:
The bypass line acts as an intermediary element that connects the closed end to the second section, providing a controlled pathway for gas discharge. This simple intermediary structure enables effective liquid-gas separation and maintains measurement reliability without requiring complex valve systems or active control mechanisms.
3Measurement precision
If the closed end has a specific inclination to prevent gas accumulation, then the measurement precision improves, but the manufacturing precision requirements increase
Solution Approach 1:
The patent specifies a range for the inclination angle (between 2° and 15°) rather than requiring a single precise value. This parameter range allows for manufacturing tolerance while maintaining the essential function of preventing gas accumulation. The specific range was determined to balance measurement precision requirements with manufacturability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively separates liquid and gas components, allowing for accurate measurement of the liquid component's property without significant influence from gas loading, ensuring robust and reliable results.
Implementation Method 1
a first section, wherein the first section has an angle of less than 20° and in particular less than 10° with respect to a horizontal
Implementation Method 2
Due to a slowing down of the flow, a separation of the liquid component and the gas component takes place locally in the end region
Implementation Method 3
The flow of the medium towards the bypass line experiences a centrifugal force in the arc-shaped section, which leads to improved separation of the liquid and gas components
