Child Seat Sensor Alert System for Vehicle Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a strong need for a system to detect and inform parents when children or pets are left behind in vehicles, wander beyond designated areas, or approach dangerous items, as existing technologies fail to effectively address these safety concerns.
Innovation Solution
A system comprising sensors integrated with child seats or vehicle seats, wireless tags, and mobile devices with alert applications that communicate when the child or pet is present, and disarm when they are no longer detected, sending notifications to parents if communication is lost or if the child or pet moves beyond a predetermined distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor-based alert system is implemented to detect children or pets in vehicles, then safety monitoring capability is improved, but device complexity increases
Solution Approach 1:
The system divides the monitoring function into separate modular components: sensors integrated into child seats or vehicle seats, wireless tags attached to children or pets, and mobile device applications. This segmentation allows each component to perform its specific function independently, improving reliability while making the overall system manageable and not overly complex.
Solution Approach 2:
The sensor system is designed to detect multiple types of objects (children and pets) using the same technical approach. The mobile device application serves multiple functions: detecting presence, determining absence, and sending alerts. This multi-functionality improves safety monitoring capability without proportionally increasing device complexity.
2Area of stationary object
If wireless communication range is extended to monitor children or pets at a distance, then monitoring coverage area is improved, but loss of information increases due to communication interruptions
Solution Approach 1:
The system continuously monitors the communication status between wireless tags and mobile devices. When communication is lost or the child/pet moves beyond the predetermined distance, the system immediately provides feedback by sending an alert notification to the parent's mobile device. This feedback mechanism ensures that information loss due to communication interruptions is minimized by promptly notifying users of the status change.
Solution Approach 2:
The system establishes predetermined distance thresholds and communication reliability criteria in advance. By setting these parameters beforehand, the system can proactively detect when communication is about to be lost or when the child/pet is approaching the boundary of the monitoring zone, allowing for timely alerts before complete communication failure occurs.

AI summary
A child seat having a sensor configured to determine the presence or absence of a child; a wireless tag in communication with the sensor; and a mobile device including an alert application and configured to communicate with the wireless tag. When the sensor detects a child in the seat, the mobile device including the alert application arms itself, and armed, when the wireless tag and the mobile device at least one of (i) lose communication, (ii) separate a pre-determined distance, or (iii) change proximity by a pre-determined distance, then the armed mobile device communicates a notification to a user.
