Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
RFID edge servers face challenges in dynamically configuring multiple RFID readers from different vendors without interrupting software application operations, and managing large volumes of RFID data effectively.
Innovation Solution
An RFID edge server system that uses metadata-based descriptions to configure RFID readers dynamically, allowing for updates without restarting the readers or the software application, and provides a method for filtering and managing RFID data through Application-Level Events (ALE) interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID readers are configured dynamically without restarting, then system availability and operational continuity are improved, but configuration complexity and management difficulty increase
Solution Approach 1:
The patent implements dynamic configuration of RFID readers through the ALE interface, allowing configuration parameters to be changed without restarting the readers. The system maintains a dynamic configuration store that can be updated in real-time, and readers periodically poll for configuration changes, enabling continuous operation with flexible configuration management.
Solution Approach 2:
The system employs feedback mechanisms where the ALE interface monitors configuration changes and notifies relevant components. The configuration manager tracks changes in the dynamic configuration store and propagates updates to affected readers, ensuring consistent state across the system without manual intervention or restarts.
2Adaptability or versatility
If multiple RFID readers from different vendors are managed through a unified interface, then system adaptability and versatility are improved, but interface complexity and configuration management difficulty increase
Solution Approach 1:
The patent creates a universal ALE (Application-Level Events) interface that serves as a standardized communication protocol between the server and multiple RFID reader vendors. This interface abstracts vendor-specific details and provides a unified method for configuration, data retrieval, and control, enabling the system to manage diverse readers through a single consistent API.
Solution Approach 2:
The ALE interface acts as an intermediary layer between the configuration manager and the RFID readers. It translates high-level configuration commands into vendor-specific protocols, shielding the complexity of different reader implementations while maintaining a simple, consistent interface for the management system.
3Productivity
If RFID data is filtered and managed through Application-Level Events interface, then data management efficiency and processing speed are improved, but system complexity and configuration requirements increase
Solution Approach 1:
The system performs preliminary data filtering and configuration setup through the ALE interface before data processing begins. Configuration parameters such as filter criteria, data formats, and processing rules are established in advance and stored in the dynamic configuration store, allowing the system to process RFID data efficiently without repeated configuration changes or complex runtime decisions.
