Solution Overview

Problem

Metallurgical plants often operate suboptimally due to lack of continuous optimization, especially when external circumstances change dynamically, leading to inefficiencies in energy usage, CO2 emissions, raw material consumption, and operational costs, as existing methods do not allow for real-time adaptation of operating parameters.

Innovation Solution

An operating method where a control device transmits operating results to a computing unit, which varies second operating parameters while keeping first parameters constant, allowing for continuous optimization of plant operation to minimize energy requirements, CO2 emissions, and raw material usage, using models and cost functions to predict and achieve optimal results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If metallurgical plants operate with fixed operating parameters after handover, then system stability is maintained, but optimization capability deteriorates

Engineering Contradiction:
Improveoptimization capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary optimization system that communicates with the control device via standardized interfaces. This intermediary analyzes operating results and generates optimized operating parameters without requiring changes to the existing control device architecture, thus maintaining system stability while enabling continuous optimization.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent separates the optimization function from the control function. The control device maintains fixed operating parameters for stability, while a separate optimization system analyzes operating results and generates recommendations. This segmentation allows independent optimization without compromising control stability.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If manual evaluation and analysis is performed by manufacturer specialists, then problem solving accuracy is improved, but time consumption and effort increase

Engineering Contradiction:
Improveevaluation accuracyVSAvoidevaluation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements an automated optimization system that performs evaluation and analysis independently without requiring manual intervention. The system automatically receives operating results, analyzes them using predefined criteria, and generates optimized parameters, enabling the system to serve itself and eliminating time-consuming manual processes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent establishes a continuous feedback loop where operating results are automatically transmitted to the optimization system, which analyzes them and returns optimized parameters. This automated feedback mechanism replaces manual evaluation cycles with continuous automatic analysis, significantly reducing response time while maintaining or improving accuracy.

Inventive Principle:
Principle #23Feedback

3Productivity

If operating parameters are not continuously optimized, then operational simplicity is maintained, but resource efficiency deteriorates

Engineering Contradiction:

Solution Approach 1:

The patent introduces an optimization intermediary that connects to the control device through standardized interfaces. This intermediary continuously analyzes operating results and generates optimized parameters without requiring complex integration into the existing control system, thus improving resource efficiency while adding minimal control complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent focuses on optimizing specific operating parameters rather than redesigning the entire control system. By continuously adjusting parameters based on operating results, the system improves resource efficiency through parameter optimization while maintaining the simplicity of the underlying control architecture.

Inventive Principle:
Principle #35Parameter changes

AI summary

A metallurgical plant has at least one plant part (1). The plant part (1) is operated with first and second operating parameters (BP1, BP2) at a particular time. An operating result (BE) is established on the basis of the operation of the plant part (1) according to the first and second operating parameters (BP1, BP2). The operating result (BE) is recorded. At least the operating result (BE) is transmitted from a control device (5) of the first plant part (1) to a computing unit (9). The computing unit (9) varies the second operating parameters (BP2), but not the first operating parameters (BP1), and thereby determines varied second operating parameters (BP2') associated with the first operating parameters (BP1). The computing unit (9) transmits the varied second operating parameters (BP2') back to the control device (5) of the first plant part (1). The control device (5) of the first plant part (1) uses the varied second operating parameters (BP2'), after the transmission of the varied second operating parameters (BP2'), when the first operating parameters (BP1) are established.
