Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If first-principles models are used to optimize refinery operations, then manufacturing precision is improved, but device complexity and ease of operation worsen due to requiring expert personnel and extended execution time

Engineering Contradiction:
Improveproduction accuracyVSAvoidmodel complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent creates a digital twin (virtual model) that replicates the behavior of the physical refinery process. This digital twin can be updated and optimized without affecting the actual operation, allowing complex first-principles modeling to be performed on copies rather than the live system, thus reducing operational complexity while maintaining precision

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system performs preliminary optimization calculations using the digital twin before implementing changes to the actual refinery operations. This allows complex computations to be completed in advance on the virtual model, reducing the execution time and complexity burden on the live system while maintaining high production accuracy

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If first-principles models are used to optimize refinery operations, then manufacturing precision is improved, but loss of time increases due to extended execution time

Engineering Contradiction:
Improveproduction accuracyVSAvoidoptimization time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system performs preliminary optimization calculations using the digital twin before implementing changes to the actual refinery operations. This allows complex computations to be completed in advance on the virtual model, reducing the execution time and complexity burden on the live system while maintaining high production accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates a digital twin (virtual model) that replicates the behavior of the physical refinery process. This digital twin can be updated and optimized without affecting the actual operation, allowing complex first-principles modeling to be performed on copies rather than the live system, thus reducing operational complexity while maintaining precision

Inventive Principle:
Principle #26Copying

3Ease of operation

If traditional control systems are used across multiple refineries, then ease of operation is maintained, but adaptability worsens due to non-uniform optimization across different refineries

Engineering Contradiction:
Improvecontrol simplicityVSAvoidoptimization uniformity
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements a universal digital twin framework that can be deployed across multiple refineries. This single platform adapts to each specific refinery's characteristics through data-driven modeling, providing consistent optimization capabilities across different facilities while maintaining ease of operation through a standardized interface

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

Solution Approach 2:

The system dynamically adjusts model parameters based on each refinery's specific conditions, feedstock variations, and operational characteristics. This allows the same control platform to adapt to different refineries by changing parameters rather than requiring custom solutions for each facility, achieving both uniformity and adaptability

Inventive Principle:
Principle #35Parameter changes
