Electronic Seal RFID Integration for Secure Cargo Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mechanical seals for storage spaces, such as cargo containers, rely on manual registration and management of identification numbers, which is time-consuming and insecure, as the numbers can be easily reproduced, compromising safety.
Innovation Solution
An electronic seal integrating RFID technology with a mechanical seal, featuring a main body and an insertion bolt with an identification chip and antenna, allowing for secure and automated identification and management of sealed articles, with detection of tampering or substitution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual registration and management of identification numbers is used, then the mechanical seal can be identified and managed, but it wastes time and manual work
Solution Approach 1:
The patent replaces manual mechanical registration systems with an electronic RFID-based identification system. The RFID tag embedded in the seal body automatically transmits identification information when approached by a reader, eliminating the need for manual registration and reducing time consumption while maintaining identification functionality.
Solution Approach 2:
The RFID-enabled seal performs self-identification without requiring manual intervention. The seal automatically responds to identification requests by transmitting its unique identifier, allowing the system to manage seals autonomously and improving productivity while reducing manual work time.
2Ease of operation
If the identification number is visible on the mechanical seal, then it can be easily identified and managed, but it can be reproduced, decreasing security
Solution Approach 1:
The patent uses RFID technology to create a digital copy of the identification information that cannot be physically replicated. The RFID tag contains a unique identifier that can be read remotely without exposing the physical seal to copying, thereby maintaining security while enabling easy identification through electronic means.
Solution Approach 2:
The RFID tag acts as an intermediary between the physical seal and the identification system. Instead of displaying identification numbers on the seal surface where they could be copied, the RFID tag provides a secure electronic interface that transmits identification information only when needed, preventing reproduction while maintaining ease of identification.
3Reliability
If the insertion bolt is locked in the main body, then the seal is secure, but it cannot be detached without cutting
Solution Approach 1:
The patent incorporates a dynamic locking mechanism where the insertion bolt can be automatically locked into the main body during sealing operations and subsequently detached through controlled means. This dynamic system maintains security during use while enabling planned detachment for maintenance or relocation, balancing reliability with ease of repair.

AI summary
An electronic seal includes a main body, an insertion bolt, and an identification circuit. Thus, the electronic seal has a determined identification code so that the identification host can rapidly identify the article (or storage space) sealed by the electronic seal, and the sealed article is identified and managed easily and conveniently by provision of the electronic seal, thereby saving the manual work.
