Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security alarm systems for portable consumer articles are vulnerable to sophisticated theft methods, and they face challenges with wire management, leading to increased costs and inefficiencies, as intelligent thieves can bypass simple sensors, and mechanical systems are prone to defeat by severance or disconnection.
Innovation Solution
An alarm system utilizing smart sensors with unique addresses and a master-slave controller architecture, where smart sensors communicate periodically with slave controllers to verify their state and generate alarms if compromised, and a microcontroller-based system manages sensor addresses and operations over a bus network, preventing unauthorized removal or tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If simple sensors are used in alarm systems, then the system is easier to manufacture and operate, but intelligent thieves can bypass the sensors leading to reduced reliability
Solution Approach 1:
The patent replaces simple mechanical sensors with smart sensors that have electronic identification capabilities. Each smart sensor includes a unique ID stored in memory and can communicate its status to the controller, making it difficult for thieves to bypass or remove without triggering an alarm.
Solution Approach 2:
The smart sensors continuously communicate their status and identification information to the controller. The controller verifies the sensor's ID against stored addresses and monitors for unauthorized removal or tampering, providing continuous feedback that enhances security while maintaining system reliability.
2Device complexity
If mechanical tethers are used for security, then the system is simpler and cheaper, but it is prone to defeat by severance or disconnection
Solution Approach 1:
The patent eliminates mechanical tethers and replaces them with electronic smart sensors that have unique identification capabilities. The sensors are attached to portable articles and communicate their status electronically to the controller, making them immune to mechanical severance or disconnection issues.
Solution Approach 2:
Instead of relying on physical continuity through mechanical tethers, the system uses electronic copies of identification data stored in the sensor's memory. The controller maintains a database of valid sensor addresses and verifies them electronically, replacing the need for continuous physical connection.
3Reliability
If multiple sensors are connected via cables to the alarm monitoring station, then each sensor can be monitored individually, but cables interfere with one another and wire management becomes complex
Solution Approach 1:
The patent extracts the identification and communication functionality from the sensor housing and integrates it into a small electronic unit that can be attached to the portable article. This eliminates the need for separate cable connections to each sensor while maintaining individual monitoring capability.
Solution Approach 2:
The smart sensor combines multiple functions into a single integrated unit: the actuator, unique ID memory, and communication interface are merged into one compact device. This eliminates the need for separate wiring for each sensor and simplifies the overall system architecture.

AI summary
An alarm system for monitoring portable articles comprises a smart sensor for operatively engaging a portable article. The smart sensor includes an actuator having a secured state and an unsecured state relative to the portable article. A memory stores a sensor address. A controller has a sensor bus operatively connected to the smart sensor. The controller includes a memory storing sensor addresses. The controller is operative to periodically communicate with the smart sensor to determine state of the sensor and to read the sensor address. The controller generates an alarm when the smart sensor is in the unsecured state or if the sensor address read from the smart sensor is not stored in the memory.
