Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional methods are used to manage ammonia cracking plants, then device complexity is reduced, but reliability deteriorates under emergency conditions

Engineering Contradiction:
Improvestable operation under emergency conditionsVSAvoidcomplex interaction between components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a digital twin model that is a virtual copy of the physical ammonia cracking plant. This digital replica includes all components and their interactions, allowing comprehensive simulation of emergency scenarios without adding physical complexity to the actual plant. The digital twin enables reliable emergency management through virtual testing and analysis.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system performs preliminary analysis by simulating multiple emergency scenarios in the digital twin model before they occur in the physical plant. Control scenarios are pre-generated and optimized through virtual testing, allowing the actual plant to respond more reliably to emergencies without complex real-time decision-making.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If digital twin model with real-time simulation is implemented, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvestable operationVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The digital twin model serves multiple functions: it simulates normal operation, tests emergency scenarios, generates control strategies, and provides training capabilities. This multi-functionality consolidates what would otherwise require separate systems into a single unified platform, managing complexity while enhancing reliability.

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

3Reliability

If complex emergency scenario analysis is performed, then reliability is improved, but loss of time increases

Engineering Contradiction:
Improveemergency situation managementVSAvoidscenario generation and analysis time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system pre-generates control scenarios through simulation in the digital twin model before actual emergencies occur. By performing the complex analysis work in advance during normal operation, the system eliminates time delays when real emergencies need to be managed, improving both reliability and response time.

Inventive Principle:
Principle #10Preliminary action
