Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID tags are used to track inventory items, then inventory tracking capability is improved, but cross-reads between adjacent items occur causing measurement errors
Solution Approach 1:
The patent applies local quality by creating location-specific virtual fences with customized geographical boundaries for different retail display areas. Each display location receives tailored geofence parameters (coordinates, radius, altitude) that adapt to the specific spatial characteristics of that location, preventing cross-reads while maintaining accurate tracking for each item position.
Solution Approach 2:
The patent introduces a third dimensional layer (geographical spatial coordinates) to the traditional RFID tracking system. By overlaying virtual fences with latitudinal, longitudinal, and altitude parameters onto the two-dimensional retail display, the system creates three-dimensional boundary zones that precisely delimit item locations and prevent cross-read interference between adjacent items.
2Measurement precision
If geographical mapping is implemented to prevent cross-reads, then measurement precision is improved, but system complexity increases
Solution Approach 1:
The system employs self-service mechanisms where the mobile device automatically performs functions including capturing item images, extracting RFID data, determining geographical coordinates, creating virtual fences, and uploading information to the server. This automation eliminates manual configuration complexity while maintaining precise item location tracking through the geographical mapping system.
Solution Approach 2:
The patent introduces a server as an intermediary that centralizes the complex geographical mapping computations, virtual fence management, and data coordination tasks. The server receives information from mobile devices, processes the geographical coordinate data, manages the virtual fence database, and coordinates with RFID readers, thereby isolating complexity from the client devices and simplifying their functionality.
3Loss of information
If real-time inventory data is collected and displayed, then information availability is improved, but data processing time and system load increase
Solution Approach 1:
The system performs preliminary actions by pre-processing and storing item information (images, RFID data, geographical coordinates) in the server database before actual inventory queries occur. When inventory data is needed, the system retrieves pre-processed information rather than generating it in real-time, significantly reducing data processing time while maintaining complete information availability.
Solution Approach 2:
The patent implements continuous useful action by maintaining persistent connections between mobile devices, RFID readers, and the server, enabling real-time data synchronization and continuous inventory tracking. The system continuously collects, processes, and updates inventory information without interruption, ensuring information is always current while distributing processing loads across the network to prevent bottlenecks.

Data Source
AI summary
According to various embodiments, a supply chain management system may provide dynamic information regarding items in manufacturing, storage, inventory, or retail processes by detecting RFID tags embedded on the items. A supply chain management system may also be configured to determine current inventory and regulate what items are stocked and restocked on displays. A split-screen showing detected items and instructions or information pertaining to the items may facilitate accurate and efficient execution of process steps by an employee or user. Supply chain management systems may also provide for re-tagging items with lost or damaged RFID tags and finding items lost from inventory due to lost or damaged RFID tags. Furthermore, a supply chain management system may include RFID tags affixed to point of purchase displays and include information regarding the point of purchase display within a database.
