Security Container Alarm Integration for Theft Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security devices for merchandise fail to effectively deter theft as they only sound an internal alarm if compromised, and the security gate alarm remains inactive when merchandise is taken through the gate, making it difficult to identify thieves, especially in crowded areas, and suffer from sensitivity issues due to numerous EAS tags.
Innovation Solution
A lockable security container with an integrated alarm system that triggers both internal and external alarms if the container is opened unauthorized or approaches a security gate without deactivation, featuring a slider mechanism that arms and disarms the alarm, ensuring continuous detection even after passing through the gate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If EAS tags are attached to all merchandise, then theft detection capability is improved, but sensitivity problems occur due to the large number of tags causing false alarms or missed detections
Solution Approach 1:
The security system is segmented into two independent parts: individual EAS tags on merchandise and a centralized alarm control unit. The control unit processes signals from multiple tags and determines whether to trigger an alarm based on programmed criteria, preventing individual tag failures from causing system-wide sensitivity issues.
Solution Approach 2:
An alarm control unit serves as an intermediary between the EAS tags and the alarm output. This mediator processes the signals from numerous tags, filters out false positives, and only triggers the alarm when genuine theft is detected, resolving the sensitivity problem caused by having many tags in circulation.
2Reliability
If security gate alarms are activated at high sensitivity, then unauthorized EAS tag removal is detected, but false alarms increase due to the large number of legitimate EAS tags on merchandise
Solution Approach 1:
The alarm control unit implements feedback processing of EAS tag signals. It monitors the presence and status of multiple tags over time, analyzing patterns to distinguish between legitimate merchandise (tags that remain with purchased items) and unauthorized removal (tags that are taken without purchase). This feedback mechanism allows the system to maintain high detection reliability while minimizing false alarms.
3Device complexity
If only internal alarm is used in security devices, then device complexity is reduced, but detection effectiveness is limited to immediate vicinity only
Solution Approach 1:
The patent merges the internal alarm system with the external security gate alarm system into a unified security solution. The alarm control unit can trigger both the internal alarm in the security device and the external gate alarm simultaneously, creating a coordinated response that covers both immediate and remote detection needs without significantly increasing overall system complexity.

AI summary
A security storage container securely retains an item of merchandise and typically includes a base and lid. An alarm system in the container is activated when the container is locked and deactivated when the container is unlocked. The alarm system may include a flashing LED, an EAS tag for activating a security gate, and a sound-emitting device which may emit a loud alarm upon an attempt to pry the lid from the base or upon the container entering into proximity of a security gate.
