Rescue System Server Notification Logic for Child Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for locating and protecting children, such as those with dementia or lost children, often result in excessive notifications to guardians due to frequent detection within the child's usual activity range, leading to unnecessary alerts and resource allocation.
Innovation Solution
A rescue system utilizing cameras mounted on movable bodies, like vehicles, communicates with a server to identify and notify guardians only when a child is detected outside their predetermined activity range, and assesses accompanying individuals to determine if they are acquaintances or potential threats, thereby optimizing notification and protection efforts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a system continuously monitors and notifies guardians whenever a child is detected, then the child's safety is maximally protected, but guardians receive excessive notifications even for normal activities within their usual range
Solution Approach 1:
The system applies different notification rules based on the child's location relative to their usual activity range. When the child is within the predetermined range, no notification is sent. When the child is outside the range, a notification is sent to the guardian. This localized differentiation resolves the contradiction by making the notification behavior context-dependent rather than uniform.
Solution Approach 2:
The system changes the notification parameter (whether to send a notification) based on the spatial parameter (child's position relative to usual activity range). By monitoring the child's position and comparing it to the predetermined range, the system dynamically adjusts the notification behavior, sending notifications only when the child's position falls outside the acceptable range.
2Reliability
If the system notifies guardians for all detections, then no safety concern is missed, but resources are wasted on unnecessary alerts and responses
Solution Approach 1:
The system differentiates between normal and abnormal situations based on the child's location. By establishing a predetermined usual activity range, the system can locally determine whether a detection requires notification. Detections within the range are treated as normal and do not trigger notifications, while detections outside the range are treated as abnormal and do trigger notifications.
Solution Approach 2:
The system performs partial monitoring by only triggering notifications for detections outside the predetermined range, rather than notifying for all detections. This partial action approach maintains safety coverage for abnormal situations while avoiding the resource waste of notifying for normal, expected situations.
3Measurement precision
If the system uses multiple cameras on movable bodies to track the child, then detection accuracy is improved, but the complexity of the system increases
Solution Approach 1:
The system uses movable bodies (vehicles) that serve multiple functions: they are equipped with cameras for child detection, has communication capabilities to report to the server, and can move to track the child's location. This multi-functionality approach improves detection accuracy without proportionally increasing system complexity, as the same movable platform performs multiple roles.
Solution Approach 2:
The server acts as an intermediary that receives information from multiple cameras on different movable bodies, processes the data, and determines whether the child is within or outside the predetermined range. This intermediary approach allows the system to leverage multiple detection points for improved accuracy while centralizing the complex processing logic in the server rather than in each individual camera or vehicle.

AI summary
A rescue system identifies and rescues a protection target, using information from a camera. The rescue system includes: a plurality of movable bodies each equipped with a camera; and a server configured to communicate with the plurality of movable bodies. The server is configured to (a) identify the protection target, using movable-body information from the plurality of movable bodies, and (b) provide a protector of the protection target with notification about positional information on the protection target, when the protection target is identified and a position where the protection target is detected is out of a predetermined range.
