Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple pressure sensors are disposed in the fluid lines for leak detection and pressure monitoring, then measurement precision and reliability are improved, but device complexity and installation effort increase

Engineering Contradiction:
Improvepressure measurement accuracyVSAvoidnumber of pressure sensors
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The pressure sensor is designed to perform multiple functions: it can measure pressure at the inlet when the valve is in the first closed position, measure pressure at the outlet when the valve is in the second closed position, and detect leaks in different sections of the fluid line. This multi-functionality allows a single sensor to replace what would traditionally require multiple sensors, thereby reducing device complexity while maintaining measurement precision

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If multiple pressure sensors are installed to cover various applications, then measurement precision is improved, but installation effort and cost increase

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The valve system with a single pressure sensor provides universal monitoring capability for both inlet and outlet pressure measurements. By utilizing the valve's two closed positions to redirect fluid flow and expose different sections to the pressure sensor, the system achieves comprehensive pressure monitoring without requiring multiple sensor installations, thereby reducing installation effort and cost

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Device complexity

If a single pressure sensor is used for multiple applications, then device complexity is reduced, but measurement precision may deteriorate

Engineering Contradiction:
Improvenumber of pressure sensorsVSAvoidpressure measurement accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system dynamically switches between different measurement modes by changing the valve position. The valve can be moved to the first closed position for inlet pressure measurement or to the second closed position for outlet pressure measurement. This dynamic reconfiguration allows the single pressure sensor to accurately measure pressure at different locations at different times, maintaining measurement precision while reducing device complexity

Inventive Principle:
Principle #15Dynamics
