Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional tamper-evident strips rely on human knowledge and thoroughness for detection, are aesthetically undesirable, and are costly and unreliable in ensuring security and safety, particularly in high-risk environments like air transportation.
Innovation Solution
Integration of RFID technology into tamper-evident strips and sensors that provide a more accurate and efficient method for detecting tampering through radio frequency identification, allowing for automated status indication and reduced reliance on visual inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tamper-evident strips are used, then tamper detection is provided, but they rely on human knowledge and thoroughness making them unreliable and costly
Solution Approach 1:
The patent replaces manual visual inspection of tamper-evident strips with an automated RFID reading system. The RFID reader automatically queries the RFID tag on the strip and displays its status without requiring human inspection, thereby improving reliability and productivity simultaneously
Solution Approach 2:
The RFID tag on the tamper-evident strip automatically provides its status information when queried by the RFID reader. The system serves itself by automatically indicating whether the strip is intact or compromised without requiring human interpretation
2Illumination intensity
If traditional tamper-evident strips with bright colors and bold lettering are used, then visibility is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The patent uses color-changing technology where the RFID tag or associated indicator changes color based on the strip's status. An intact strip displays one color (e.g., green) while a compromised strip displays another color (e.g., red), providing visibility without requiring bold lettering or distracting designs
Solution Approach 2:
The RFID tag acts as an intermediary between the physical strip and the display system. It communicates the strip's status electronically through the RFID reader, allowing the actual strip to be aesthetically pleasing while the digital display provides clear status indication
3Productivity
If automated RFID reading system is implemented, then inspection efficiency is improved, but device complexity increases
Solution Approach 1:
The patent employs a universal RFID reading system that can read multiple RFID tags across different locations and strip types using the same hardware and software. This multi-functional approach improves efficiency without proportionally increasing complexity
Solution Approach 2:
The system uses standard RFID technology that leverages existing infrastructure and protocols. By copying proven RFID implementations from other industries, the patent avoids reinventing complex systems while achieving automated inspection

AI summary
A system for tamper detection includes a security device and a data device. The security device has a first portion disposable on a first side of a separation boundary of a separable object, and a second portion disposable on a second side of the separation boundary. The security device further includes a first Radio Frequency Identification (RFID) circuit configured to provide a first return signal. The data device includes a microprocessor and system memory, an RFID reader and a radio antenna. The data device is configured to send and receive radio frequency signals with the first RFID circuit, and to recognize the first return signal as indicating an untampered condition of the separable object.
