Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If RFID tags with limited storage capacity are used to mark underground assets, then the system remains simple and cost-effective, but detailed field notes and coordination information cannot be adequately recorded
Solution Approach 1:
The patent transitions from two-dimensional RFID tag storage to three-dimensional hierarchical storage by introducing a central database layer. The RFID tag serves as a key/index that links to extensive data stored centrally, effectively adding a vertical dimension to the storage architecture. This resolves the contradiction by providing unlimited data capacity through the central database while maintaining the simplicity of RFID tags in the field.
Solution Approach 2:
The patent introduces a central database as an intermediary between the RFID tag and the full information set. The RFID tag contains a unique identifier that mediates access to the comprehensive data stored centrally. This intermediary structure allows the system to maintain both the simplicity of RFID tags and the capacity to store detailed information, resolving the storage capacity limitation.
2Adaptability or versatility
If multiple RFID technologies are used to manage different underground assets, then various asset types can be tracked, but compatibility issues arise among different RFID systems
Solution Approach 1:
The patent implements a universal central database architecture that can interface with multiple RFID technology types. The system is designed to accept data from various RFID standards and protocols, translating them into a common format for centralized storage and retrieval. This universal approach maintains reliability by ensuring consistent data access regardless of the specific RFID technology used, while preserving adaptability to support diverse asset tracking needs.
3Reliability
If field personnel use paper logs to record inspection data, then no special equipment is needed, but data may be misplaced, delayed, or lost before incorporation into central records
Solution Approach 1:
The patent replaces the mechanical paper-based logging system with an electronic data capture system. Field personnel use RFID readers and mobile devices to electronically record inspection data, which is then automatically transmitted to the central database. This substitution eliminates the risks of paper logs being misplaced or delayed, ensuring data security and immediate incorporation into central records, while significantly reducing the time required for data entry and processing.
4Ease of operation
If work crews maintain separate records for different underground assets, then each crew can manage its own data, but coordination among crews is impaired
Solution Approach 1:
The patent merges individual crew records into a unified central database while maintaining crew-specific access permissions. Each work crew retains autonomy to manage and access their own data through the central system, but all records are consolidated in one location. This merging approach enables real-time coordination among crews by making all asset information visible and accessible to authorized personnel, eliminating information silos while preserving operational independence.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides secure, centralized storage and coordination of data for underground assets, ensuring accurate and timely recording of field notes and improved collaboration among field personnel, while preventing data loss and ensuring compatibility across different RFID technologies.
Implementation Method 1
Such passive RFID tags, instead, obtain electrical power by scavenging some of the electrical power from radio signals that are used to interrogate the RFID tag
Implementation Method 2
Sensing of the magnetic field is used to guide fieldworker to the location of the RFID marker
Data Source
AI summary
A system for managing underground assets with RFID tags provides for expanded virtual storage by wirelessly linking the field RFID tag reader to a centralized database through a unique series code in the RFID tag. Real-time updating of information about underground assets coordination between multiple users may be accomplished through use of the central database as an information broker.
