Portable Wireless Device for Emergency Rescue Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rescue request systems cannot transmit the current situation of a victim, such as injury level, which hinders quick and accurate response during emergencies, especially in areas where mobile phone calls are not possible.
Innovation Solution
A portable wireless device with a wireless communication unit, position information acquisition unit, and operation unit that generates and transmits rescue requests along with situation information, including injury status, to a server for timely and appropriate rescue operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile phone is used to report rescue requests, then communication is possible in normal areas, but mobile phone calls are not possible in accident zones
Solution Approach 1:
The patent introduces a relay satellite as an intermediary communication device to enable rescue request transmission in accident zones where mobile phone networks are unavailable. The portable terminal communicates with the relay satellite, which then forwards the rescue request to the server, bridging the communication gap in areas without cellular coverage.
2Loss of information
If only position information is transmitted, then the rescue request can be sent, but the current situation of the victim cannot be communicated
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple state information items (injury status, consciousness, breathing, etc.) that can be selected by the user. The operation unit is designed with buttons corresponding to different states, allowing the user to quickly indicate their condition without complex input operations. This preparation of information categories in advance enables comprehensive situation communication with minimal user effort during the emergency.
3Reliability
If comprehensive situation information is transmitted, then appropriate rescue operations can be performed, but the transmission system becomes more complex
Solution Approach 1:
The patent segments the information transmission system into distinct functional modules: a state information acquisition unit for collecting victim condition data, a position information acquisition unit for location data, and a wireless communication unit for transmission. The state information itself is segmented into multiple independent items (injury status, consciousness, breathing, etc.), each that can be selected independently. This segmentation allows comprehensive information collection while maintaining system manageability and clarity.
Data Source
AI summary
A portable wireless device includes a wireless communication unit, a position information acquisition unit, an operation unit, and a control unit, in which a rescue request and state information are generated by operation of the operation unit, and the generated information is transmitted from the wireless communication unit together with position information acquired by a position acquisition unit.
