Voice-Activated Personal Safety Wearable for Concealed Emergency Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety devices for outdoor enthusiasts require manual activation, are cumbersome, and can be easily disabled by attackers, failing to provide immediate alerting and tracking capabilities.
Innovation Solution
A wearable personal safety system with a concealable voice-activated unit and GPS that automatically alerts authorities and emits an audible alarm upon activation, with a secondary device to deter attackers and continue tracking even if the secondary device is destroyed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual alert button device is carried, then the user can activate safety functions, but the user must hold the device in hand and press the button for several seconds which is cumbersome and delays activation
Solution Approach 1:
The patent replaces the mechanical button-pressing system with a voice recognition system. The controller activates the alarm function by recognizing a predetermined voice command through the microphone, eliminating the need for manual button operation and reducing activation time from several seconds to near-instantaneous response.
Solution Approach 2:
The device automatically detects and responds to voice commands without requiring manual intervention. The system serves itself by having the controller monitor audio input continuously and automatically trigger the alarm sequence when the predetermined voice is detected, freeing the user's hands and enabling immediate activation.
2Reliability
If a visible deterrent device is worn, then attackers are warned that authorities have been alerted, but the device can be easily discovered and removed by attackers
Solution Approach 1:
The patent divides the safety system into two separate components: a concealed primary device containing the controller, microphone, and GPS, and a separate secondary visible device that displays deterrent messages. This segmentation ensures that if the visible device is removed or destroyed, the primary device remains intact and continues to provide tracking and alarm functions.
Solution Approach 2:
The visible device serves as an intermediary between the user and potential attackers, displaying messages that deter criminal behavior without being essential to the core safety function. The concealed primary device acts as the true safety mechanism that operates independently of the visible deterrent component.
3Reliability
If the device sends alerts continuously, then authorities are kept informed of the user's location, but energy is consumed continuously reducing battery life
Solution Approach 1:
The patent implements periodic transmission of location data to authorities rather than continuous transmission. The controller sends updated GPS coordinates at predetermined time intervals, maintaining reliable tracking information while significantly reducing power consumption compared to continuous real-time transmission.
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
Provides immediate and continuous alerting and tracking capabilities, deterring attackers and ensuring authorities are notified, even if the secondary device is tampered with, without requiring manual activation.
Implementation Method 1
a global positioning system (GPS) locating device that acquires location information
Implementation Method 2
the microphone being configured to hear the activation expression
Implementation Method 3
the controller operable to determine a location of the user and send the location with an alert via the transmitter
Implementation Method 4
The activated secondary device immediately plays an audible alarm to warn a stalker that authorities have been alerted

AI summary
A system of ensuring personal safety of an individual includes a concealable device and a deterrent device, the concealable device for tracking the location of the individual and to alert authorities of an emergency situation upon hearing an activation expression from the individual, and the deterrent device being in wireless communication with the concealable device to audibly warn an assailant upon activation of the concealable device by the activation expression.
