Solution Overview

Problem

Current metallurgical industry plants face challenges in managing and maintaining changeable segments in continuous casting plants due to manual data entry and lack of integrated data management, leading to inefficiencies in tracking unit conditions, maintenance schedules, and production processes.

Innovation Solution

Implementing a cyber-physical system where units in the metallurgical industry plant are equipped with sensors and communication means to store and exchange data about their virtual state, allowing for decentralized data processing and real-time monitoring across operating areas, enabling autonomous handling and optimizing production processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If manual data entry and lack of integrated data management are used, then device complexity is reduced, but information availability and measurement precision deteriorate

Engineering Contradiction:
Improvedata availabilityVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent creates a virtual copy (digital twin) of the physical segment that mirrors its state and behavior. This virtual model allows data to be accessed, analyzed, and managed without adding physical complexity to the actual segment structure. The virtual copy captures all relevant parameters and maintains them in sync with the physical object through automated sensing and data exchange.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces manual data entry and mechanical data collection methods with automated electronic sensing and communication systems. Sensors, RFID tags, and communication modules automatically capture and transmit data, eliminating the need for manual recording and reducing information loss while the software platform integrates and manages the data centrally.

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

2Productivity

If decentralized data processing and real-time monitoring are implemented, then productivity and reliability improve, but device complexity increases

Engineering Contradiction:
Improvemaintenance efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the data management system into modular components: individual sensors on each segment, local processing units, communication modules, and a central software platform. Each segment can operate independently with its own data collection and transmission capabilities, allowing the system to scale without overwhelming complexity. The modular architecture enables incremental implementation and easier maintenance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a universal data management platform that handles multiple functions: real-time monitoring, predictive maintenance, inventory management, and production planning. This single integrated system serves all these purposes simultaneously, improving productivity across multiple operational areas while avoiding the need for separate complex systems for each function.

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

3Reliability

If accurate and timely data is provided for maintenance planning, then reliability improves, but measurement and detection difficulty increases

Engineering Contradiction:
Improvemaintenance reliabilityVSAvoiddata collection difficulty
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent enables segments to self-monitor and self-report their condition through integrated sensors and communication modules. Each segment automatically detects its own state (position, temperature, wear indicators) and transmits this data without requiring external inspection or manual measurement. This self-service approach ensures continuous accurate data collection while minimizing the effort and expertise required for data gathering.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements continuous feedback loops where sensor data from segments is constantly monitored, analyzed, and used to adjust maintenance schedules and operations in real-time. The system provides feedback to operators and automatically triggers maintenance actions when thresholds are exceeded, ensuring reliable maintenance planning based on actual segment conditions rather than fixed schedules.

Inventive Principle:
Principle #23Feedback

AI summary

A metallurgical plant (1) is disclosed, comprising a plurality of operating areas (2) and at least one movable unit (3) – e.g., a tool – with a unit (4) for sending, receiving, and storing data associated with the unit (3). The operating areas (2) include a communication means (5) for communicating with the unit (4) of the unit (3) and a sensor network (6) for detecting units (3) located within the operating area (2). The operating areas (2) are represented as virtual spaces (7). The data stored in the unit (4) virtually represents the virtual state (8) of the unit (3), where the state relates, for example, to temperature, wear, or maintenance history. This virtual state (8) can be accessed at any time without the need for measurements or time-consuming research.A user (16) can view the virtual space (7) and status (8) of a unit (3) on a mobile device (11). Furthermore, the position and other information about a unit (3) requiring maintenance can be displayed. The user (16) can, for example, replace the displayed unit (3) and save the replacement as a new virtual status (8) in the unit (4). This improves the autonomous or automated handling of units (3) of the plant (1). The invention also relates to a method for operating a plant (1) in the metallurgical industry.
