Wireless Security Fob for Theft Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security solutions for small consumer electronics, such as smartpens and tablets, restrict user interaction due to physical tethers, compromising the hands-on experience and increasing theft risks, as they are cumbersome and aesthetically unappealing, while also being costly and resource-intensive for retailers to manage.
Innovation Solution
A wireless security system that uses a lightweight security fob attached to the device via a tether, allowing for free handling within a designated area while monitoring the device's location and alerting when it exceeds a predetermined perimeter, using ultra-wideband communication and NFC for pairing, and featuring power-saving modes to prolong battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical tether system is used to secure small consumer electronics, then theft prevention is improved, but user interaction freedom deteriorates
Solution Approach 1:
The patent replaces the mechanical tether system with a wireless monitoring system using RFID tags and base stations. The RFID tag attached to the device communicates wirelessly with base stations to track device location and trigger alarms when unauthorized removal is detected, eliminating the need for physical tethers while maintaining security.
Solution Approach 2:
The patent introduces an intermediary RFID tag as a mediator between the device and the security system. The tag serves as a lightweight intermediary that enables theft prevention through wireless communication without imposing the physical constraints of traditional tethers on the device or user interaction.
2Reliability
If a physical tether system is used to secure small consumer electronics, then security is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The patent replaces the visible mechanical tether system with an invisible wireless RFID-based security system. This substitution eliminates the aesthetic compromise of having visible tethers or anchors attached to devices, while maintaining security through wireless monitoring and alarm capabilities.
3Ease of operation
If employees manually facilitate hands-on interaction for each customer, then customer service quality is improved, but operational cost increases
Solution Approach 1:
The patent enables self-service through the wireless security system that automatically monitors device locations and triggers alarms for unauthorized removal. This automated system eliminates the need for employee intervention in security monitoring, allowing customers to freely interact with devices while reducing labor costs.
4Reliability
If devices are kept behind glass panes or in secured locations, then theft prevention is improved, but customer accessibility deteriorates
Solution Approach 1:
The patent replaces physical barriers like glass panes with a wireless RFID monitoring system. This allows devices to be freely accessible to customers in open displays while maintaining theft prevention through automated tracking and alarm capabilities, eliminating the need for restrictive physical enclosures.
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
Enables a seamless user experience similar to untethered devices while providing effective security against theft, reducing employee costs and enhancing customer satisfaction by allowing free handling within a secure perimeter, with extended battery life and efficient communication.
Implementation Method 1
An ultra-wideband transceiver and antenna for communication with the base station
Implementation Method 2
A first NFC chip for pairing a plurality of security fobs with the base station
Data Source
AI summary
A wireless, proximity-based security system for securing or tracking a valuable object. The system includes a base station and a plurality of security fobs. The security fobs are tracked via an ultra-wideband transceiver relative to an outer perimeter. An administrator fob pairs each of the security fobs with the base station. An audible alarm emits from base and/or the fobs when the location of the security fob is detected to be beyond the outer perimeter. A haptic alarm emits from fob when the location of the security fob is detected to be beyond a sub-perimeter.
