Problem
The complexity of electrical switchgear in switch cabinet arrangements often leads to incomprehensible interconnections for technicians due to insufficient documentation and changes over the service life, making maintenance and service difficult.
Innovation Solution
A switch cabinet arrangement with a human-machine interface featuring an optical display that shows a circuit diagram of the electrical switchgear, where components have machine-readable identifiers for unique assignment and status indication, along with sensors for monitoring technical values, and a data interface for updating the diagram with changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical switchgear components are modified or added over service life, then the electrical switchgear functionality is improved or adapted, but the wiring complexity and documentation accuracy deteriorate
Solution Approach 1:
The patent applies preliminary action by pre-equipping each electrical component with a machine-readable identifier (such as a data matrix code) during manufacturing. This allows the component to carry its own identification information from the outset, enabling automatic recognition and documentation updates when modifications are made, thus preventing documentation deterioration while maintaining adaptability.
Solution Approach 2:
The patent uses copying by creating a digital representation (circuit diagram) that mirrors the physical electrical switchgear configuration. When components are modified, the system automatically updates the digital copy to reflect changes, maintaining accurate documentation without manually tracking wiring complexity.
2Loss of information
If traditional documentation methods are used for electrical switchgear, then initial wiring can be recorded, but maintenance serviceability deteriorates due to outdated information
Solution Approach 1:
The patent implements feedback by using sensors and reading devices that automatically detect machine-readable identifiers on components and update the circuit diagram in real-time. This continuous feedback loop ensures documentation remains accurate and current, directly improving maintenance serviceability by providing up-to-date information.
Solution Approach 2:
The system applies self-service by enabling automatic documentation updates through the interaction of reading devices, sensors, and processing units that autonomously track component changes and maintain the circuit diagram without requiring manual intervention, thus preventing information loss and improving repair ease.
3Ease of operation
If machine-readable identifiers and optical display are added, then serviceability is improved through visual feedback, but device complexity increases
Solution Approach 1:
The patent applies universality by making the human-machine interface serve multiple functions: it displays the circuit diagram, shows component status information, provides visual feedback through optical indicators, and enables interaction with the electrical switchgear. This multi-functionality improves serviceability while minimizing the addition of separate dedicated components.
Solution Approach 2:
The patent uses an intermediary approach by introducing a processing unit that acts as a mediator between the sensors/reading devices and the human-machine interface. This intermediary processes data from various sources and presents it in a unified visual format, improving serviceability while managing system complexity through centralized data handling.
