Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If flow rate is concentrated in a specific pipe among multiple pipes, then the flow rate in that pipe increases, but the overall system stability deteriorates and other pipes suffer from insufficient flow

Engineering Contradiction:
Improveflow rateVSAvoidsystem stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The patent implements a feedback mechanism where the digital twin model continuously monitors flow rates in all pipes and automatically adjusts valve positions to equalize flow distribution. When flow concentration is detected in a specific pipe, the system responds by reducing the valve opening in that pipe and increasing it in others, creating a closed-loop control system that maintains stable flow distribution across the entire network

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent creates a digital twin (virtual copy) of the physical pipe network that replicates the exact structure, parameters, and real-time operating conditions. This digital model allows for simulation of flow distribution scenarios and automatic generation of control strategies without affecting the actual physical system, enabling safe optimization of flow equalization

Inventive Principle:
Principle #26Copying

2Device complexity

If conventional methods are used to describe system interactions, then the system structure remains simple, but the ability to model complex interactions between components deteriorates

Solution Approach 1:

The patent creates a digital twin (virtual copy) of the physical pipe network that replicates the exact structure, parameters, and real-time operating conditions. This digital model allows for simulation of flow distribution scenarios and automatic generation of control strategies without affecting the actual physical system, enabling safe optimization of flow equalization

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent transforms the physical system into a digital representation where parameters such as flow rates, pressures, temperatures, and valve positions are continuously measured and updated in the digital twin. This parameter transformation enables complex interactions to be modeled through computational algorithms rather than physical experimentation

Inventive Principle:
Principle #35Parameter changes

Core Design Contradiction:

Solution Approach 1:

The digital twin model serves multiple functions simultaneously: it monitors real-time operating conditions, simulates various flow distribution scenarios, optimizes valve positioning strategies, and provides predictive analytics. This multi-functionality consolidates what would otherwise require separate systems into a single integrated platform, managing complexity through consolidation rather than multiplication

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