Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If local sensors and controllers are used to monitor airflow and pressure rise to detect surge events in early stages, then surge detection accuracy is improved, but system cost increases

Engineering Contradiction:
Improvesurge detection accuracyVSAvoidsystem cost
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces a mediator (centralized processing system with machine learning algorithms) that processes data from existing remote sensors to achieve accurate surge detection without requiring expensive local sensors and controllers at each compressor station. The intermediary system aggregates and analyzes data from multiple sources to compensate for the lack of local measurement capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of installing physical local sensors at each compressor, the system creates a virtual model of compressor behavior using machine learning algorithms that replicate the functions of local surge detection. The AI model copies the detection capability of physical sensors through software-based analysis of available remote data.

Inventive Principle:
Principle #26Copying

Solution Approach 1:

The system performs preliminary action by detecting surge events at their earliest stages using machine learning analysis of performance parameters, enabling preventive measures to be taken before flow reversal occurs. The AI model identifies subtle changes in compressor efficiency and performance parameters that precede actual surge events, allowing operators to take corrective action in advance.

Inventive Principle:

Solution Approach 2:

The system implements continuous feedback monitoring of compressor performance parameters, comparing real-time data against learned patterns from historical data to detect early signs of surge. The feedback mechanism provides ongoing assessment of surge risk, enabling timely intervention to prevent flow reversal while maintaining reliable operation.

Inventive Principle:

Solution Approach 1:

The machine learning system performs preliminary detection of conditions that lead to surge events, analyzing performance parameters to identify when the compressor is approaching surge conditions during high-pressure ratio operation. By detecting early warning signs in the performance data, the system enables preventive action before surge occurs, allowing the compressor to operate efficiently at high pressure ratios with reduced surge risk.

Inventive Principle:
Principle #10Preliminary action
