Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for securing and tracking keys and other valuable items in high-security facilities are inefficient and prone to loss, leading to security breaches and costly repercussions.
Innovation Solution
A wireless item loss prevention system using a belt-mounted unit and a remote key ring with magnetic sensors and alarms that activate when the item moves beyond a predetermined radius, providing a preemptive solution to prevent loss and misplacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional key control procedures are implemented, then security is improved, but operational efficiency deteriorates due to complex sign-in/out procedures and identification verification
Solution Approach 1:
The patent replaces manual key control procedures (mechanical/administrative system) with an electronic tracking system using RFID tags, readers, and a database. The system automatically records key issuance, location, and return, eliminating the need for manual sign-in/out sheets and identification verification while maintaining security through electronic audit trails.
2Device complexity
If manual key tracking procedures are used, then device complexity is reduced, but item loss prevention capability deteriorates
Solution Approach 1:
The key tracking system operates autonomously by automatically detecting key issuance and return events through RFID readers, updating the database without human intervention. The system self-monitors key locations and generates alerts for unauthorized removal or overdue returns, eliminating the need for manual tracking while providing comprehensive loss prevention.
3Ease of operation
If keys are carried freely by personnel, then ease of operation is improved, but security risk increases due to potential loss or misplacement
Solution Approach 1:
The system provides continuous feedback on key location and status through the database and alert mechanisms. When a key is removed from the secure area or not returned by the deadline, the system generates notifications to authorized personnel, enabling real-time monitoring and immediate response to potential security incidents while allowing free key carriage.
4Reliability
If extensive key control procedures are implemented, then security is improved, but loss of time increases due to verification and accounting processes
Solution Approach 1:
The system performs preliminary tracking and monitoring of keys throughout their lifecycle. By continuously recording key locations and statuses in the database, the system prepares advance alerts for potential issues, eliminating the need for time-consuming end-of-period verification and accounting processes while maintaining security oversight.
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
The system effectively prevents item loss by alerting the user with vibrations, audio, and visual alarms when the item exceeds a 10-15 meter radius, ensuring timely recovery and maintaining security without the need for extensive re-keying or re-pinning.
Implementation Method 1
magnetic sensors between the item and the belt

AI summary
An item loss prevention system for protecting from the loss of items from a user, and more specifically to an electronic device utilizing a wireless connection between a remote unit attached to an item, such as a set of one or more keys, and a host or belt unit attached to the user, to prevent the loss of the item. The system includes magnetic sensors between the item and the belt, which are Hall type magnetic sensors. An alarm activates when the item attached to the remote unit, such as a key is separated from the host unit. A multiple of additional host units and the remote units pairs can operate properly in proximity to each other, and are tuned to respond to rolling average signal strength monitoring, to indicate a separation distance requiring an alarm to the user.
