Car Seat Child Alert System Using Sensor Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a risk of children or pets being left unattended in vehicles, leading to dangerous conditions due to forgetfulness, as existing systems lack effective sensors to detect and alert guardians promptly.
Innovation Solution
A sensor-based alert system equipped with proximity, weight, and ignition sensors that detect the presence of a dependent in a vehicle, alerting the guardian via a wireless key fob or mobile application, with additional features like an interactive sticker to minimize anxiety and optional contact with emergency services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors are integrated into the car seat to detect dependent presence, then detection reliability is improved, but device complexity increases
Solution Approach 1:
The system divides the detection function into multiple independent sensor components (weight sensor, proximity sensor, ignition sensor) that work together to provide comprehensive detection. Each sensor handles a specific aspect of dependent presence detection, improving overall reliability while maintaining manageable complexity through functional segmentation.
Solution Approach 2:
The sensor system is designed to perform multiple detection functions simultaneously - weight detection, proximity detection, and ignition status monitoring - all within a single integrated car seat system. This multi-functionality approach improves detection reliability without requiring separate independent systems for each function.
2Loss of time
If wireless alert systems are implemented to notify guardians, then response time is improved, but energy consumption increases
Solution Approach 1:
The wireless alert system operates periodically rather than continuously - the Bluetooth communication and mobile application notifications are triggered only when the sensor system detects that a dependent has been left unattended. This periodic activation significantly reduces energy consumption compared to continuous monitoring and transmission, while still achieving rapid response time when needed.
3Object-affected harmful factors
If interactive stickers and sound systems are added to reduce dependent anxiety, then emotional well-being is improved, but device complexity increases
Solution Approach 1:
The interactive stickers and sound system serve as intermediary elements between the sensor detection system and the dependent child. When a dependent is detected as unattended, these intermediaries provide comfort through visual and auditory stimuli, reducing anxiety without requiring direct complex interaction systems. The stickers act as mediators that translate the system's detection into child-friendly comfort provisions.
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
The system effectively alerts guardians to unattended dependents, preventing injuries and reducing anxiety, with adjustable settings and ecologically-friendly materials ensuring reliable operation.
Implementation Method 1
The system of the present invention employs sensors to detect the presence of a dependent within a specially fitted car seat
Implementation Method 2
Such an alert system would preferably employ a proximity sensor and/or weight sensor that would accurately detect if a child was left alone in a vehicle
Implementation Method 3
The sensors (10) relay data to a central controller (30), which is preferably integrated into the car seat (20) or into a third-party addition
Implementation Method 4
The alert is preferably conveyed via a conventional wireless signal such as Bluetooth or similar technology, to a key fob and/or mobile device located on the guardian's person
Data Source
AI summary
A system and application to alert parents or guardians to the solitary status of a dependent accidentally left within the confines of a vehicle is described. The system alerts individuals in the event that a dependent such as a child is left behind via the use of sensors configured to detect the presence of the dependent, and determine if he or she is alone. Upon recognizing that the dependent has been left alone, an alert is sent to the parent or guardian's wirelessly connected key fob and/or mobile device via a proprietary mobile application. Simultaneously, the system employs an active display sticker, configured to calm or entertain the dependent left within the vehicle until the alerted parent or guardian returns.
