Mobile Phone Emergency Event Detection and Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile phones do not effectively activate emergency services when users are in emergency situations, such as having their phones turned off, batteries removed, or emergency calls disconnected, leading to a lack of immediate data collection and transmission for assistance.
Innovation Solution
A mobile phone system that detects predefined emergency events, disables unnecessary services to conserve battery power, and enables data collection services like audio recording, image capture, and GPS location tracking, transmitting this data to emergency agencies through a mobile telecommunications network, with the option to prioritize services based on available battery power and the type of event.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile phone enables data collection services to collect and transmit data during emergency situations, then the quality and completeness of emergency information is improved, but the battery power consumption increases
Solution Approach 1:
The system pre-loads and caches emergency data (contact information, medical records, location data) before an emergency occurs. When an emergency event is detected, this pre-prepared data can be immediately transmitted without requiring real-time data collection, thus reducing battery consumption during the critical emergency response period while ensuring complete emergency information is provided.
Solution Approach 2:
The system selectively activates only the minimum necessary data collection services based on the type of emergency detected. For example, if a fall is detected, only location and contact information are transmitted, rather than activating all possible sensors and cameras. This partial action approach provides sufficient emergency information while conserving battery power.
2Reliability
If the mobile phone monitors multiple events to detect emergency situations, then the detection accuracy and response capability are improved, but the device complexity increases
Solution Approach 1:
The system uses a single event detection module that handles multiple types of emergency events (fall detection, button press, voice command, location change) through unified detection logic. This multi-functional approach improves emergency detection accuracy across different scenarios while avoiding the complexity of separate dedicated detection systems for each event type.
Solution Approach 2:
The system combines multiple detection methods (accelerometer data, button press detection, voice recognition, GPS tracking) into a single integrated event detection service. By merging these detection capabilities into one coordinated system rather than separate independent systems, the patent achieves high detection accuracy while reducing overall system complexity through centralized management.
3Speed
If the mobile phone transmits collected data to emergency agencies, then the speed of emergency response is improved, but the network dependency and potential failure points increase
Solution Approach 1:
The system pre-establishes communication channels and formats emergency data for transmission before an actual emergency occurs. Data is staged in a ready-to-transmit buffer with pre-configured communication protocols, enabling immediate transmission when an emergency is detected. This reduces transmission delay while including fallback mechanisms that can attempt alternative transmission methods if the primary network fails, thus maintaining reliability.
Solution Approach 2:
The system implements feedback mechanisms to monitor transmission status and network availability. If data transmission to emergency agencies fails or is delayed, the system receives feedback about the failure condition and automatically attempts alternative transmission methods or notifies local contacts. This feedback loop ensures rapid response when possible while maintaining system robustness through error handling and retry logic.

AI summary
A mobile phone is configured to detect emergency events and control services enabled on the mobile phone in response to the emergency events. The mobile phone may be configured to detect events such as the mobile phone being turned off or a battery being removed. When the mobile phone detects an event, the mobile phone enables one or more emergency services on the mobile phone to collect and transmit data that may be used by emergency personnel. Other services may be disabled on the mobile phone to conserve battery power.
