Electronic Tag Device Unifying UHF and HF Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic tag systems for baggage management, which incorporate both UHF and HF communication systems, face challenges in associating identification information across different communication interfaces, leading to increased man-hours and inefficient use of computer resources due to non-unified identification information between UHF and HF communication IC tags.
Innovation Solution
An electronic tag device is designed with a configuration that includes UHF and HF interface units, along with a control unit and storage, which generates and uses common identification information shared across both interfaces, allowing seamless association and management of identification data across different communication systems, thereby reducing the burden on staff and improving resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different identification information systems (UHF TID and HF UID) are used for different communication interfaces, then compatibility with respective communication systems is improved, but association between interfaces becomes difficult and manual work increases
Solution Approach 1:
The patent introduces a server as an intermediary that mediates between UHF and HF identification systems. The server stores correspondence relationships between TID (UHF identification) and UID (HF identification), enabling automatic association without direct complexity in the electronic tag device itself. This resolves the contradiction by maintaining interface-specific identification while providing a centralized mapping mechanism.
Solution Approach 2:
The electronic tag device is designed to support multiple communication interfaces (UHF and HF) with different identification systems simultaneously. By incorporating both TID and UID in the same physical tag and establishing their correspondence, the system achieves multi-functionality where a single tag can operate across different communication protocols without requiring separate tagging systems.
2Ease of operation
If multiple communication interfaces (UHF and HF) are added to the electronic tag, then user convenience and self-service capability are improved, but identification information management becomes more complex
Solution Approach 1:
The patent segments the identification information management into two parts: (1) the electronic tag device stores both TID and UID locally, and (2) the server stores the correspondence relationship between these identifiers. This segmentation allows the tag to maintain multiple identification systems while the server handles the complexity of unification, preventing information loss and ensuring consistent identification across interfaces.
3Productivity
If barcode reading is replaced by RFID reading, then recognition rate is improved and staff burden is reduced, but additional interfaces and identification systems are required
Solution Approach 1:
The patent merges barcode recognition functionality with RFID recognition functionality into a single electronic tag device. The tag contains both visual display elements (for barcode-like scanning) and RFID communication capabilities (for wireless identification). This combination maintains the high recognition rate of RFID while integrating it with traditional barcode scanning workflows, avoiding the need for completely separate systems.
