Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional sensors are used to detect phase boundary position, then the phase separator can operate with simple sensor arrangement, but it cannot reliably separate fluids with different optical densities or refractive indices including liquids and gases

Engineering Contradiction:
Improveability to separate different fluid typesVSAvoidseparation reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent replaces conventional mechanical or electrical sensors with an optical detection system using a laser beam. The laser beam detects the phase boundary position by measuring refraction and reflection changes when passing through different fluid phases, enabling reliable detection and separation of fluids with different optical densities including liquids and gases.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the detection parameter from conventional electrical or mechanical measurements to optical parameters (refraction index, reflection coefficient). By monitoring changes in laser beam refraction and reflection at the phase boundary, the system can distinguish between different fluid types based on their optical properties, improving versatility and reliability.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If the phase boundary control system uses simple sensors, then the device complexity is low, but the measurement precision of phase boundary position is insufficient

Engineering Contradiction:
Improvephase boundary position detection accuracyVSAvoidsensor arrangement complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical position measurement systems with an optical laser-based detection system. The laser beam provides precise measurement of phase boundary position by detecting refraction and reflection changes, achieving high measurement precision while maintaining relatively simple device structure.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Stress or pressure

If the phase separator is designed for high-pressure applications, then it can handle high-pressure fluid mixtures, but the device complexity increases due to pressure-resistant design requirements

Engineering Contradiction:
Improvepressure resistanceVSAvoidstructural complexity
Core Design Contradiction:
Stress or pressureVSDevice complexity

Solution Approach 1:

The patent divides the phase separator into distinct functional modules: a pressure-resistant separation chamber, a laser detection system, and control electronics. This segmentation allows the pressure-resistant design to be concentrated in the separation chamber while keeping other components simpler, reducing overall device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a laser beam as an intermediary for phase boundary detection that does not require direct contact with high-pressure fluids. The optical detection system operates externally or through transparent walls, isolating the sensitive detection components from high-pressure environments and simplifying their design.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A phase separator and a method for its operation are disclosed. In a phase separation chamber, two fluids are separated. The phase separation chamber has an inlet and two outlets, the latter being vertically spaced apart. By means of control electronics and a respective valve or micropump, the respective volume flow of the two fluids through each outlet is controlled according to a sensor arrangement. The sensor arrangement is located in the outlet zone of the phase separation chamber. The sensor arrangement includes a laser and a laser detector arrangement, which can detect refraction and/or reflection of the laser beam.
