Wearable Beacon Relay for Emergency Data Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical emergencies, there is a need for immediate and timely communication of vital information to ensure appropriate medical attention, which existing technologies often fail to provide efficiently.
Innovation Solution
A method and apparatus that utilize a wearable device to send beaconing messages with emergency information to a user device, which then initiates an emergency call and relays the information to an emergency service entity via wireless links, establishing a secure communication channel for timely medical assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a wearable device transmits emergency information directly to emergency services, then the transmission speed is improved, but the device complexity and power consumption increase
Solution Approach 1:
The patent introduces a user device as an intermediary between the wearable device and emergency services. The wearable device transmits emergency information to the user device, which then forwards it to emergency services. This mediator approach allows the wearable device to maintain simple architecture while achieving rapid emergency information delivery through the user device's communication capabilities.
2Loss of time
If emergency information is transmitted immediately upon detection, then the response time is improved, but the reliability of information delivery may worsen due to unstable wireless connections
Solution Approach 1:
The system performs preliminary actions by establishing communication channels and preparing transmission paths in advance. The user device maintains readiness to receive and forward emergency information, and the system implements retry mechanisms and alternative transmission paths to ensure reliable delivery even when initial connections are unstable.
3Reliability
If the wearable device uses multiple wireless links for transmission, then the reliability of information delivery is improved, but the energy consumption increases
Solution Approach 1:
The transmission task is segmented between two devices: the wearable device handles initial detection and first-hop transmission to the user device, while the user device handles second-hop transmission to emergency services. This segmentation allows each device to use appropriate wireless links for its specific function, reducing overall energy consumption while maintaining reliability through the multi-link approach.
