Vehicle Mobile-Device Throw Detection for Covert Emergency Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Occupants in vehicles may become disoriented during emergency situations and fail to notify first responders, leading to a lack of immediate intervention.
Innovation Solution
A system with transmitters, receivers, motion sensors, and processors to detect the movement of a mobile device thrown by an occupant, determining emergency conditions based on predefined movement areas and acceleration thresholds, and automatically alerting first responders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system requires direct interaction from the occupant to notify emergency situations, then the notification can be confirmed as intentional, but the occupant may become disoriented and lose the ability to notify first responders
Solution Approach 1:
The system automatically detects and responds to emergency situations without requiring the occupant to perform manual operations. The mobile device detection system autonomously monitors for thrown devices, determines emergency conditions, and triggers alerts, allowing the occupant to simply throw the device without needing to operate any controls or interfaces.
Solution Approach 2:
The system performs preliminary detection and analysis before triggering the emergency notification. It continuously monitors for thrown mobile devices, classifies movement patterns, and determines whether emergency conditions are met before activating the alert, ensuring reliable notification while maintaining ease of operation.
2Measurement precision
If the system uses complex detection mechanisms to accurately identify emergency situations, then the accuracy of emergency detection improves, but the system complexity increases
Solution Approach 1:
The system replaces complex mechanical or manual emergency detection mechanisms with electronic sensing and signal processing. Using transmitters, receivers, and motion sensors with automated analysis algorithms provides high detection accuracy while reducing mechanical complexity compared to traditional manual or mechanical alarm systems.
Solution Approach 2:
The system uses a mobile device as an intermediary object to detect and communicate emergency situations. The thrown mobile device serves as a mediator that carries information about the emergency condition, allowing the system to accurately detect emergencies through the device's movement pattern without requiring complex direct sensing of the occupant's state.
3Speed
If the system triggers immediate alerts upon detecting any movement, then the response time to emergencies is reduced, but false alarms increase
Solution Approach 1:
The system uses feedback loops to continuously monitor movement patterns and adjust alert triggering based on classified information. The motion sensor detects movement, the processor classifies the movement type and location, and this feedback determines whether emergency conditions are met, allowing fast response while filtering out false alarms through intelligent analysis.
Solution Approach 2:
The system changes parameters such as acceleration thresholds, movement direction criteria, and location-based rules to distinguish genuine emergencies from normal movements. By adjusting these parameters dynamically based on the classified movement pattern, the system achieves both fast response time and high alert accuracy.
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 covert notification of emergency situations by allowing occupants to alert first responders without direct interaction, ensuring timely intervention.
Implementation Method 1
The motion sensor may be further configured to: determine, based on a change in a location of the mobile device being detected, an acceleration of the mobile device; and detect, based on the acceleration being greater than a threshold acceleration, that the mobile device has been thrown.

AI summary
Disclosed are a system and a method for responding to an emergency situation. The system may include a plurality of transmitters, each provided at a corresponding location of a plurality of locations of a vehicle; a receiver provided in the vehicle; a motion sensor; a processor; and a memory. The system may classify at least one of the plurality of detection areas as a movement start area and classify at least one of the plurality of detection areas as a movement end area; and determine, based on the motion sensor detecting that the mobile device has been thrown from the movement start area and has landed in the movement end area, that an emergency condition is met. The system may further include a communication circuit configured to output, based on the emergency condition being met, a signal indicating that an emergency situation has occurred.
