Emergency Rescue System with Server-Mediated Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing GPS devices used in emergency rescue situations primarily facilitate location positioning but fail to enable direct communication between the help-seeker and rescuer, leading to delayed or inefficient rescue operations, as the positioning signals are often limited to specific units and do not allow for real-time information exchange.
Innovation Solution
An emergency rescue system comprising a help-seeking device and a rescue device, both equipped with GPS positioning functions, that communicate through a server to pair and exchange messages, enabling real-time communication and location information sharing between the help-seeker and rescuer, using modules for positioning, input, processing, and transmission to package and send identification, location, and situation information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS positioning function is used to locate help-seeker, then location information can be obtained, but direct communication between help-seeker and rescuer is not enabled
Solution Approach 1:
The patent combines GPS positioning function with communication functions (messaging, audio, video) into an integrated emergency rescue system. The help-seeking device and rescue device both incorporate positioning modules and communication modules that work together, allowing location information and communication capabilities to function as a unified system rather than separate features.
Solution Approach 2:
The rescue device is designed with multi-functionality, serving both as a positioning receiver and a communication device. It can receive positioning information from help-seekers, send rescue instructions, and enable two-way communication through multiple channels (text messaging, audio, video), making a single device capable of performing multiple rescue-related functions.
2Reliability
If positioning signal is transmitted to specific units only, then signal security is maintained, but rescue response time is delayed
Solution Approach 1:
The system segments the rescue response process into multiple stages: initial help-seeking message transmission to the server, server-mediated matching with nearby rescue devices, and then direct peer-to-peer communication between help-seeker and rescuer. This segmentation allows the system to maintain security through server mediation while reducing time loss through direct communication channels once matched.
Solution Approach 2:
The server acts as an intermediary that receives help-seeking messages, determines nearby rescue devices, and facilitates the connection between help-seekers and rescuers. This intermediary approach maintains system security and reliability while enabling rapid response by automatically matching help-seekers with the nearest available rescue resources without requiring manual intervention.
3Device complexity
If help-seeking message is sent to specific rescue units, then message delivery is controlled, but rescue efficiency is reduced
Solution Approach 1:
The system dynamically determines message distribution based on real-time conditions. The server automatically calculates which rescue devices are nearby based on current positioning data, and dynamically routes help-seeking messages to the most appropriate rescuers. This dynamic approach replaces static, pre-configured message distribution with adaptive, real-time decision-making that optimizes rescue efficiency.
Solution Approach 2:
The system implements feedback mechanisms where the server continuously receives positioning information from both help-seekers and rescue devices, analyzes this data to determine optimal message routing, and adjusts message distribution in real-time. This feedback loop ensures that help-seeking messages are delivered to the most appropriate rescuers based on current spatial relationships and rescue availability, thereby improving overall rescue efficiency.

AI summary
An emergency rescue system and a handheld electronic device and an emergency rescue method are provided. The emergency rescue system comprises a help-seeking device, a rescue device and a server. The help-seeking device is used to position, and used to provide a help-seeker to input situation information to send a help-seeking message to the server. The rescue device is used to position and send a positioning message to the server. The sever is used to compare the help-seeking message and the positioning message to execute a supply-demand pairing, and used to send the help-seeking message and the positioning message to the help-seeking device and the rescue device respectively for making the help-seeking device can communicate with the rescue device.
