RFID E-Seal State Detection via Segmented Tags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing e-seals lack tamper-proofing and cannot distinguish between 'Open' and 'Non-Tampered' states, failing to provide clear status updates when not in use, and are not fully capable of tracking the product/cargo/container effectively.
Innovation Solution
The e-seal incorporates a UHF or NFC RFID tag system with activation means and tampering detection mechanisms, allowing it to differentiate between 'Open', 'Closed', and 'Tampered' states, using a bolt and flag configuration with RFID tags that emit signals based on the e-seal's state, and includes tampering detection means to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional e-seal with RFID tag is used, then remote signaling of seal identification is achieved, but the seal cannot distinguish between 'Open' and 'Non-Tampered' states
Solution Approach 1:
The seal is divided into separate functional components: a header section containing the RFID tag for identification, and a body section containing activation means and tampering detection means. This segmentation allows independent detection of different states (Open vs. Non-Tampered) through separate mechanisms, enabling precise state differentiation while maintaining remote signaling capability.
2Strength
If bolt seal with plastic covering is used, then strength and tampering evidence are improved, but the ability to provide clear status updates when not in use is lost
Solution Approach 1:
The patent replaces purely mechanical state indication with an electronic RFID-based system. The activation means and tampering detection means generate electronic signals that can be remotely read, substituting the need for physical inspection of mechanical seals while maintaining their strength and tampering evidence capabilities.
3Adaptability or versatility
If existing e-seal design is used, then passive RFID technology is supported, but tracking capability and tamper resistance are insufficient
Solution Approach 1:
The seal integrates multiple functions into a single device: the RFID tag provides universal identification and tracking capability, while the activation means and tampering detection means provide enhanced security. This multi-functional design maintains compatibility with existing RFID infrastructure while significantly improving tamper resistance and tracking reliability.

AI summary
The present invention relates in general to e-seal and in particular to electronic e-seals (e-seals) for logistic and transport use. More in detail, the invention relates to a RFID security with improved tampering resistance. The present invention is an electronic e-seal for logistic and transport use with improved tampering resistance using RFID security. The e-seal includes a lock body (1), a flag (3), a bolt (2) firmly connected to the flag (3), a first RFID tag adapted to emit an own identification signal and housed into said flag (3), and a second RFID tag (5, 6) located into said lock body (1) and adapted to emit an own identification signal when activated. The e-seal includes activation means (4) of said second RFID tag (5, 6) adapted to move from a non-activated position to an activated position, and a tampering detection means (7) located into said lock body (1).
