Disposable Cable Lock With Removable Alarm Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic article surveillance (EAS) systems can be circumvented by removing the EAS tag from merchandise, as they primarily detect the tag rather than the merchandise itself, leading to a need for additional security measures to prevent unauthorized removal or destruction of the EAS element.
Innovation Solution
A security device comprising a cable with a main body and a removable alarm module, where the cable is secured to an object using a locking mechanism, and the alarm module can be electro-mechanically coupled to the main body, providing additional alarm functionality and tamper detection, including activation upon removal or damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If EAS tags are attached to merchandise for security detection, then the security detection capability is improved, but the merchandise can still be circumvented by removing the EAS tag
Solution Approach 1:
The patent combines the EAS tag with a cable lock mechanism, merging the security detection function with the physical attachment function. The EAS tag is integrated into the cable lock assembly that physically secures the merchandise, making it difficult to separate the EAS tag from the merchandise without triggering both the alarm and the physical restraint.
Solution Approach 2:
The cable lock acts as an intermediary between the EAS tag and the merchandise. Instead of directly attaching the EAS tag to the merchandise (which can be easily removed), the cable lock serves as a mediating structure that physically constrains the merchandise while housing the EAS tag, creating an additional layer of security.
2Reliability
If integrated security layers are added to prevent EAS tag removal, then the security against tampering is improved, but the device complexity increases
Solution Approach 1:
The security device is segmented into distinct functional modules: the EAS tag for detection, the cable for physical attachment, the locking mechanism for securing, and the alarm module for alerting. This modular segmentation allows each component to perform its specific function while keeping the overall design manageable and not excessively complex.
Solution Approach 2:
The cable serves multiple functions simultaneously: it provides the physical attachment structure, conducts electrical signals between the EAS tag and alarm module, and acts as part of the locking mechanism. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity.
3Reliability
If a removable alarm module is added to provide active alarm functionality, then the alarm functionality is improved, but the ease of operation is reduced
Solution Approach 1:
The alarm module is designed with dynamic attachment and detachment capabilities through a spring-loaded locking mechanism that can be easily engaged and disengaged. The spring-loaded design provides automatic engagement when the module is inserted and allows easy removal with a simple pulling motion, maintaining ease of operation while providing reliable alarm functionality.
