Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual data collection is used to achieve precise train parking, then the train can be controlled to park precisely, but the data precision is low and the debugging period is long

Engineering Contradiction:
Improvetrain parking precisionVSAvoiddebugging period
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical debugging process with an automated neural network learning system. The system automatically collects train operation data, processes it through neural networks to identify interference factors, and generates adjusted control levels without requiring manual intervention on the debugging track, thus dramatically reducing the debugging period while maintaining parking precision

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The train control system performs self-debugging through automated data collection and processing. The neural network system automatically learns from collected operation data, identifies interference factors, and adjusts control parameters without external manual assistance, enabling the system to improve its own performance through self-service debugging

Inventive Principle:
Principle #25Self-service

2Measurement precision

If manual data collection is performed multiple times to eliminate errors, then data precision can be improved, but the debugging period becomes even longer

Engineering Contradiction:
Improvedata precisionVSAvoiddebugging period
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces repeated manual data collection with a single automated data collection followed by neural network processing. The neural network automatically analyzes the collected operation data to identify interference factors and calculate correction values, eliminating the need for multiple debugging runs and significantly reducing the time required to achieve high data precision

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The neural network learning system acts as an intermediary between raw operation data and final control decisions. It processes the collected data to extract meaningful patterns and identify interference factors, transforming raw data into actionable insights without requiring repeated collection cycles

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If the VOBC system calculates train level based on collected data, then precise parking can be realized, but the system cannot automatically identify changes in train performance or operation environment

Engineering Contradiction:
Improveparking precisionVSAvoidautomatic identification capability
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent implements a feedback mechanism where the neural network continuously monitors train operation data, compares actual performance with expected performance, and automatically adjusts control levels based on identified interference factors. This closed-loop feedback enables the system to adapt to changes in train performance or operation environment while maintaining parking precision

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The neural network learning system serves as an intermediary intelligence layer between the VOBC and the train control system. It automatically identifies changes in train performance or operation environment by analyzing operation data and generates appropriate adjustments, providing the system with adaptive capabilities without manual intervention

Inventive Principle:
Principle #24Intermediary (Mediator)
