Container Closure Security System with Tamper Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional container security systems are vulnerable to tampering, as seals can be easily broken, replaced, or duplicated, making it difficult to detect unauthorized access or contamination during shipment and storage.
Innovation Solution
A closure security system featuring an RFID tag with encrypted information, sensors, and a processing system that generates notifications upon tampering events, allowing for real-time monitoring and tracking of container integrity through a networked communication interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional seals are used for container security, then visual inspection capability is provided, but reliability against tampering is insufficient
Solution Approach 1:
The patent replaces mechanical visual inspection seals with an electronic RFID-based security system. The RFID tag stores encrypted container identification information that can be remotely verified, eliminating the need for physical seal inspection while providing more reliable tamper detection through electronic authentication.
Solution Approach 2:
The patent introduces an RFID reader as an intermediary device between the container and the verification system. This intermediary enables remote identification and authentication of container contents without direct physical contact or visual inspection, enhancing security reliability while maintaining operational efficiency.
2Measurement precision
If RFID tags with encrypted information are implemented, then measurement precision of container integrity is improved, but device complexity increases
Solution Approach 1:
The patent uses RFID tags to create an electronic copy of container identification and authentication information. This digital replica enables precise verification of container integrity and contents without requiring physical inspection, achieving high measurement precision while keeping the implementation relatively simple through standardized RFID technology.
3Loss of information
If real-time monitoring through communication interfaces is added, then loss of information about tampering is reduced, but use of energy increases
Solution Approach 1:
The patent implements periodic communication where the RFID system transmits container identification information at scheduled intervals or upon trigger events such as attempted access. This periodic action ensures timely information transmission about container status while minimizing energy consumption by keeping the communication interface dormant between transmissions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents unauthorized access and contamination by providing timely notifications of tampering events, ensuring the integrity and authenticity of products within containers, and facilitating inventory management.
Implementation Method 1
a security sensor that includes an RFID reader, the RFID reader being configured to read the RFID tag and to broadcast the encrypted information included in the RFID tag

AI summary
A container security system includes a container chassis and a closure subsystem coupled to the container chassis. The closure subsystem includes a closure chassis that prevents movement of a material between a container volume and an exterior of the container chassis via an aperture defined by the container chassis. The closure subsystem a closure security sensor that generates a closure sensor signal when the closure chassis experiences a tamper event. A first type communication interface is housed in the closure chassis and a security engine provided by the closure subsystem receives a sensor signal indicating that the closure chassis has experienced the tamper event. The security engine then provides, in response to receiving the sensor signal and using the first type communication interface, a notification to a corresponding first type communication interface that the closure chassis has experienced the tamper event.
