Warning system, monitor device and warning device for merchandise security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing merchandise anti-theft systems lack extensibility and are costly due to the need for frequent replacement of components, and they often result in false alarms, causing management fatigue and inefficiencies.
Innovation Solution
A warning system comprising a monitor device, a warning device, and a controller that can initialize and control these components, allowing for secure and flexible configuration, enabling accurate monitoring of merchandise states and reducing false alarms through a unique communication interface and preset warning modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a unique and non-replaceable corresponding relationship is established between the controller and anti-theft devices to ensure security, then security performance is improved, but system extensibility deteriorates
Solution Approach 1:
The patent implements dynamic binding between controllers and anti-theft devices through time-limited authentication tokens. The binding relationship is not fixed but changes over time, allowing the system to maintain security while adapting to different device configurations and replacements without requiring complete system reconfiguration.
Solution Approach 2:
The system changes the authentication parameter from static device identifiers to dynamic tokens that can be regenerated. This allows the same controller to work with different anti-theft devices by issuing new authentication parameters, thereby improving extensibility while maintaining security through parameter transformation rather than structural changes.
2Measurement precision
If strict and detailed principles are used to determine unauthorized accidents and unsafe states, then security detection accuracy is improved, but false alarm rate increases
Solution Approach 1:
The patent applies different monitoring thresholds and detection sensitivities to different types of events and contexts. Rather than using a single strict threshold for all security events, the system adjusts detection parameters locally based on the specific type of monitoring needed, reducing false alarms while maintaining detection accuracy for actual threats.
Solution Approach 2:
The system implements a hierarchical monitoring approach where not all parameters are monitored at maximum sensitivity simultaneously. Critical security parameters are monitored strictly, while less critical parameters use more lenient thresholds, balancing detection accuracy with false alarm reduction through selective application of monitoring intensity.
