Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a reliable and efficient method to facilitate emergency calls, especially in situations where timely assistance is critical due to injuries or accidents, particularly in sports and daily activities, where existing communication methods often fail to provide necessary information quickly enough.
Innovation Solution
A device utilizing GSM technology with satellite positioning sensors that automatically generates a voice message with the user's location and situation, allowing for immediate communication with emergency services, and optionally includes a teleconference feature with a private operational center, managed by a central cloud service, which can automatically initiate calls or allow manual activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a device for emergency calls with automatic voice message generation is implemented, then the speed of information transmission to emergency services is improved, but the device complexity increases due to integration of GSM module, GPS module, and control circuitry
Solution Approach 1:
The patent combines multiple functions (emergency calling, GPS positioning, voice message generation, and automatic activation) into a single integrated device. The control circuitry coordinates the GSM module and GPS module to work together, creating a unified emergency communication system that transmits both location and situation information simultaneously through an automated voice message.
Solution Approach 2:
The device performs preliminary actions by automatically generating and transmitting the voice message immediately upon detecting an emergency situation, without requiring user intervention. The system pre-prepares the communication by automatically assembling location data from the GPS module and emergency information, then immediately transmitting it when needed.
2Loss of time
If automatic emergency calling with voice message generation is implemented, then the response time of emergency services is improved, but the ease of operation deteriorates as the device requires automatic activation through sensors or algorithms
Solution Approach 1:
The device serves itself by automatically detecting emergency situations through sensors or algorithms and initiating the emergency call without human intervention. The system monitors its own state, determines when help is needed, and autonomously activates the emergency communication function, eliminating the need for manual operation during critical moments.
Solution Approach 2:
The device uses feedback from sensors and monitoring algorithms to detect changes in the user's state or environment that indicate an emergency situation. This feedback mechanism triggers the automatic emergency calling sequence, creating a closed-loop system that responds to real-time conditions.
3Measurement precision
If satellite positioning sensors and real-time monitoring algorithms are integrated, then the precision of location information is improved, but the energy consumption increases due to continuous satellite signal reception and data processing
Solution Approach 1:
The device employs periodic action by updating GPS location information and monitoring data at specific intervals rather than continuously. The control circuitry is designed to activate sensors and algorithms at predetermined time intervals or upon triggering events, reducing energy consumption while maintaining adequate location precision for emergency response.
