Disposable RFID Lock with Spring-Triggered Antenna Destruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locking systems used to secure goods or assets during transportation are inefficient in detecting tampering or harmful activities, as visual examination is time-consuming and may not reveal concealed attempts.
Innovation Solution
A cost-prohibitive, disposable RFID locking apparatus that includes an RFID tag, a locking member, and a disabling member, where the RFID tag emits a signal that is disabled upon tampering, indicating potential harmful activities through the loss of signal detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional locks are used to secure goods or assets, then the goods or assets are protected against tampering, but it is difficult and time-consuming to detect whether harmful activities were attempted or have occurred
Solution Approach 1:
The patent replaces the mechanical visual inspection system with an RFID electromagnetic field-based detection system. The RFID tag continuously transmits security status information wirelessly, eliminating the need for manual visual examination of locks and enabling remote, real-time monitoring of tampering events.
Solution Approach 2:
The patent implements a feedback mechanism where the RFID tag provides continuous information about the locking mechanism's integrity status. When tampering is detected through the spring mechanism, the RFID tag's signal changes to indicate the security breach, providing immediate feedback without requiring physical inspection.
2Measurement precision
If visual examination of locks is performed to detect tampering, then some harmful activities may be identified, but the examination is expensive and inefficient and may not reveal concealed attempts
Solution Approach 1:
The patent replaces inefficient manual visual inspection with an automated RFID detection system that continuously monitors locking mechanism integrity. This substitution dramatically improves both detection accuracy by capturing concealed tampering events and productivity by eliminating time-consuming manual examinations.
Solution Approach 2:
The locking mechanism performs self-monitoring through the spring-loaded RFID disabling mechanism. When tampering occurs, the mechanism automatically detects the structural change and disables the RFID tag, providing self-service detection without requiring external examination resources.
3Reliability
If locks are replaced with similar-looking locks to conceal harmful activities, then the appearance remains unchanged, but the RFID signal detection can reveal the replacement
Solution Approach 1:
The patent merges the RFID tag with the locking mechanism structure itself, making the RFID component an integral part of the lock assembly. This integration ensures that any attempt to replace the lock will necessarily involve the RFID tag, making tampering detection straightforward while maintaining a simple overall device structure.
Solution Approach 2:
The patent uses RFID electromagnetic field technology to replace complex mechanical verification systems. Instead of requiring physical inspection of lock components, the electromagnetic RFID signal provides a simple, reliable method to detect whether the locking mechanism has been tampered with or replaced.
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
Enables quick identification and location of assets and detects potential tampering by ensuring the RFID tag's signal is only emitted when the locking mechanism is intact, providing a visual and electronic confirmation of security breaches.
Implementation Method 1
radio frequency identification ('RFID') technology to identify, track, and locate goods or assets
Implementation Method 2
The locking member extends outwardly from within the housing and is configured to compress a spring into a loaded state
Implementation Method 3
The disabling member is disposed near the spring inside the housing and is configured to damage the antenna and/or the chip, such that the signal cannot be emitted, upon release of the spring from the loaded state
Data Source
AI summary
Implementations described and claimed herein provide an RFID locking apparatus including an RFID tag, a locking member, and a disabling member. The RFID tag is disposed inside a housing and has a chip and an antenna that emits a signal. The locking member extends outwardly from within the housing and is configured to compress a spring into a loaded state. The disabling member is disposed near the spring inside the housing and is configured to destroy the antenna and/or the chip, such that the signal cannot be emitted, upon release of the spring from the loaded state. The RFID locking apparatus is configured to release the spring when the locking member is damaged.
