Solution Overview
Problem
Current methods for managing life cycle information of switchgear cabinets in industrial installations are limited, relying on paper-based documentation and lacking comprehensive data visualization, which hinders efficient commissioning, maintenance, and repair processes.
Innovation Solution
A computer-aided system that links data sheet information of installed modules with function information and stores it in a central archive database, enabling dynamic updates and access through a decentralized user terminal, facilitating commissioning, maintenance, and repair by integrating QR codes and RFID for identification and image documentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If paper-based documentation is used for switch cabinet information, then simplicity and low cost are achieved, but information completeness and accessibility are limited
Solution Approach 1:
The patent creates digital copies of switch cabinet information including data sheet information A, function information B, test and acceptance information C, commissioning information D, maintenance information E, and repair information F. These digital copies are stored in a centralized database and can be accessed via decentralized terminals, replacing paper-based documentation while maintaining information completeness.
Solution Approach 2:
The patent transitions from two-dimensional paper documentation to multi-dimensional digital information storage and access. Information is organized in a structured database with multiple access points and can be retrieved through various decentralized terminals (mobile devices, tablets, computers), adding spatial and temporal dimensions to information accessibility.
2Ease of operation
If comprehensive life cycle information is stored centrally, then information accessibility and completeness improve, but data consistency and security management become more difficult
Solution Approach 1:
The system implements feedback mechanisms where information is automatically updated across the network. When data sheet information A or function information B is modified in the centralized database, these changes are automatically reflected in all decentralized terminals. The system also provides feedback on information completeness by checking whether required test and acceptance information C is available before commissioning.
Solution Approach 2:
The system performs preliminary checks on information completeness before commissioning. The centralized database verifies that all necessary test and acceptance information C, commissioning information D, and associated data are present and consistent before allowing system commissioning, preventing data consistency issues from arising.
3Productivity
If detailed technical information is integrated into switch cabinet documentation, then maintenance and repair efficiency improve, but documentation complexity and storage requirements increase
Solution Approach 1:
The patent segments comprehensive life cycle information into distinct categories: data sheet information A, function information B, test and acceptance information C, commissioning information D, maintenance information E, and repair information F. Each segment can be independently accessed, updated, and managed, allowing maintenance personnel to retrieve only the specific information needed for their tasks without being overwhelmed by complete documentation sets.
Solution Approach 2:
The centralized database serves multiple functions simultaneously: it stores and manages all life cycle information, provides access points through various decentralized terminals, ensures data consistency through feedback mechanisms, and supports different user needs (commissioning, maintenance, repair) through a single unified system.
4Measurement precision
If QR codes and RFID tags are used for module identification, then identification accuracy and speed improve, but implementation cost and complexity increase
Solution Approach 1:
The patent introduces QR codes and RFID tags as intermediary elements between the built-in modules and the information management system. These markers serve as mediators that link physical modules to their corresponding digital information in the centralized database, enabling automatic identification and information retrieval without direct human intervention or complex manual processes.
