Child Safety Seat Alarm with Proximity Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seat alarm systems fail to effectively notify drivers of an infant's presence in the vehicle when they step away, often requiring vehicle modifications, relying on sophisticated computer systems, or using fragile chest straps, and do not monitor the driver's proximity.
Innovation Solution
A child safety seat with a remote alarm system integrated with the vehicle key, using a buckle mechanism to broadcast a signal when latched, and a personal device carried by the driver to alert them if they move out of range, ensuring both audible and visual alerts are triggered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing child safety seat alarm systems are used, then the driver is notified of infant presence, but the systems require vehicle modifications or rely on sophisticated computer systems
Solution Approach 1:
The patent uses a portable receiver device that acts as an intermediary between the transmitter in the car seat and the driver. This portable device receives signals from the transmitter and provides visual/audio alerts to the driver, eliminating the need for vehicle modifications or sophisticated computer systems while maintaining reliable alarm notification.
2Reliability
If existing alarm systems are used, then the driver is alerted, but they do not monitor the driver's proximity to the vehicle
Solution Approach 1:
The patent incorporates a proximity sensor in the portable receiver device that continuously monitors the driver's proximity to the vehicle. When the driver moves beyond a predetermined distance from the vehicle, the device provides additional visual alerts, creating a feedback loop that ensures the driver is notified of both the infant's presence and their own absence from the vehicle.
3Ease of operation
If chest straps are used for the alarm system, then the alarm can be activated, but the straps are fragile and can be easily damaged
Solution Approach 1:
The patent extracts the electronic components from the fragile chest strap and relocates them to the durable car seat structure and the portable receiver device. The transmitter is integrated into the car seat's harness system, eliminating the need for fragile chest straps while maintaining easy alarm activation through the existing seat belt buckle mechanism.
4Ease of manufacture
If a portable receiver device is used, then vehicle modifications are avoided, but the device must be carried by the driver
Solution Approach 1:
The portable receiver device is designed to perform multiple functions: receiving signals from the transmitter, providing visual and audio alerts, monitoring driver proximity, and serving as a key fob. This multi-functionality makes the device universally useful and encourages drivers to carry it, as it combines safety monitoring with everyday key management.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides a cost-effective, vehicle-modification-free alarm system that effectively notifies the driver of an infant's presence through both auditory and visual cues, ensuring the driver's proximity is monitored, thus preventing accidental forgetting.
Implementation Method 1
When released from the housing, the latching pin broadcasts a signal to the housing while the housing is in range
Implementation Method 2
audible and visual alerts are triggered
Implementation Method 3
audible and visual alerts are triggered
