Child Safety Notification System with Surrounding Sound Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing notification systems for children do not allow guardians to accurately assess the safety situation of the child when they move away, as they only provide distance-based notifications without context.
Innovation Solution
A notification system that includes a terminal information acquisition unit to gather position information of both parent and child terminals, a detection unit to identify when the child moves beyond a predetermined distance or location, a sound acquisition unit to capture the surroundings of the child terminal, and a sound information output unit to transmit this information to the parent terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If distance-based notification is implemented, then child safety monitoring is enabled, but situation awareness is insufficient
Solution Approach 1:
The notification is segmented into multiple information layers: basic distance alert and detailed situation information. The system first notifies the guardian of distance threshold violation, then provides segmented details including sound environment, location context, and time information, allowing progressive awareness without overwhelming the guardian.
Solution Approach 2:
The system transitions from one-dimensional distance monitoring to multi-dimensional situation awareness by incorporating sound environment data, location information, and temporal context. This dimensional expansion allows guardians to assess the child's situation comprehensively without being physically present.
2Loss of information
If sound acquisition is added to provide situation context, then information completeness is improved, but device complexity increases
Solution Approach 1:
The child terminal is designed as a multi-functional device that simultaneously performs location tracking, sound acquisition, and communication functions. By making the terminal universal, the system avoids adding separate dedicated devices for each function, thereby managing complexity while providing comprehensive monitoring.
Solution Approach 2:
Multiple monitoring functions (position tracking, sound sensing, communication) are merged into a single integrated child terminal system. This consolidation reduces the number of separate components and simplifies the overall system architecture while delivering comprehensive situation awareness.

AI summary
A notification system includes a terminal information acquisition unit configured to acquire position information of a parent terminal (see FIG. 2) and position information of a child terminal (see FIG. 3) that performs communication with the parent terminal, and to acquire a positional relationship between the parent terminal and the child terminal, a detection unit configured to detect that the positional relationship between the parent terminal and the child terminal satisfies a condition that is set in advance, a sound acquisition unit configured to acquire a sound of surroundings of the child terminal, in a case where the detection unit detects that the positional relationship between the parent terminal and the child terminal satisfies the condition that is set in advance, and a sound information output unit configured to output, from the parent terminal, information that is based on the sound acquired by the sound acquisition unit.
