Disaster Safety Confirmation Signal System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing safety confirmation system fails to reliably notify users of a portable phone that a user is safe after a disaster, as it sends information without voluntary confirmation, and lacks information on heavily damaged areas, hindering rescue efforts.
Innovation Solution
A system that transmits a signal to terminals to prompt voluntary responses during disasters, determines if the information received is voluntarily provided, and performs safety-related processing based on this determination, allowing reliable notification of user safety and providing evacuation information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system automatically returns information without voluntary confirmation, then the response rate increases, but the reliability of safety notification decreases
Solution Approach 1:
The system pre-distributes confirmation requests to multiple terminals before a disaster occurs, so that when a disaster happens, the terminals are already prepared to send confirmation signals automatically. This preliminary preparation ensures both high response rates and reliable safety notifications, as the terminals are pre-configured to send confirmations without requiring voluntary user action during the disaster.
2Speed
If the system sends safety information without verifying voluntary response, then the notification speed increases, but the accuracy of safety confirmation decreases
Solution Approach 1:
The system implements a feedback mechanism where terminals send confirmation signals back to the server, and the server verifies these signals before sending safety notifications. This feedback loop ensures that only genuine safety confirmations are processed, maintaining high accuracy while preserving fast notification speeds through automated verification.
3Productivity
If the system collects detailed disaster area information, then the rescue efficiency improves, but the system complexity increases
Solution Approach 1:
The system enables terminals to automatically collect and transmit their own location and status information without requiring complex centralized data gathering mechanisms. Each terminal independently provides its own data, which simplifies the overall system architecture while still achieving comprehensive disaster area information collection for efficient rescue operations.

AI summary
In order to solve a problem that a service relating to the safety of a user of a terminal cannot be provided with high reliability, this device is provided with: a transmission means that takes a predetermined opportunity related to the occurrence of a disaster to transmit a signal urging a reply by a spontaneous operation to a connected first terminal; a determination means that determines whether or not the information transmitted from the first terminal in response to the transmission is spontaneous information transmitted by the spontaneous operation of a user of the first terminal; and a processing means that, when the determination means determines that the information is the spontaneous information, performs predetermined processing related to the safety of the user of the first terminal. The predetermined processing may be processing for transmitting safety information indicating that the user of the first terminal is safe to a second terminal possessed by a family.
