Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional monitoring methods are used for stackers, then the system is simple to operate, but the prediction accuracy of stacker state is insufficient

Engineering Contradiction:
Improveprediction accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs simulation execution of work tasks before actual execution to predict potential failures. Historical work data and maintenance data are analyzed in advance to build prediction models, allowing the system to identify potential issues before they occur during actual stacker operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The prediction system is divided into multiple independent modules: data acquisition module for collecting historical data, simulation execution module for virtual task completion, state prediction module for analyzing failure probabilities, and result generation module for outputting predictions. This modular architecture improves accuracy while managing complexity through clear separation of functions.

Inventive Principle:

2Measurement precision

If simulation execution is performed to predict stacker state, then the prediction accuracy is improved, but the computational time and resources increase

Engineering Contradiction:

Solution Approach 1:

Instead of executing actual physical tasks for testing and prediction, the system creates virtual copies of work tasks in a simulation environment. The simulation execution module replicates stacker operations digitally, allowing comprehensive state prediction without consuming real operational time or physical resources.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system performs simulation and prediction calculations before actual stacker operations begin. By completing the computational work in advance during planning phases, the system avoids time-consuming calculations during critical operational periods, reducing real-time computational burden.

Solution Approach 1:

The data processing system is segmented into specialized modules: historical work data acquisition for operational records, historical maintenance data acquisition for service records, and integrated analysis module for combining both data types. Each module handles specific data processing tasks, improving reliability through comprehensive analysis while managing complexity through functional separation.
