Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unattended individuals, including children, pets, and adults, are at risk of harm or death due to extreme temperature fluctuations and CO2 poisoning inside parked vehicles, as existing solutions are inadequate in detecting life presence and environmental hazards accurately and are often vehicle-specific or require installation during fabrication.
Innovation Solution
A standalone system utilizing an Ultra-Wideband (UWB) radar sensor, temperature sensor, CO2 sensor, GPS, and communication modules to detect life presence, monitor environmental conditions, and send notifications and alerts to caregivers and emergency services, with a solar panel for power and a mobile device interface for configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera-based monitoring system is used to detect life inside a vehicle, then movement detection is possible, but the system cannot accurately detect life when the subject is asleep or unconscious with minimal movement
Solution Approach 1:
The patent replaces camera-based optical detection with radar-based electromagnetic wave detection. The radar sensor detects life presence by measuring minute movements caused by breathing and heartbeat, which are imperceptible to cameras. This substitution enables accurate detection of unconscious or sleeping subjects without requiring complex image processing algorithms.
Solution Approach 2:
The system changes the detection parameter from visual movement (camera) to electromagnetic wave reflection patterns (radar). By detecting the subtle expansion and contraction of the chest during breathing and the rhythmic movements of the heartbeat, the radar can identify life presence even when no visible movement occurs, thus improving detection accuracy for stationary subjects.
2Measurement precision
If temperature and movement monitoring are used to detect life inside a vehicle, then environmental hazards can be identified, but the system cannot reliably distinguish between life presence and environmental conditions
Solution Approach 1:
The patent combines multiple detection methods into a unified system: radar for life presence detection, temperature sensors for thermal monitoring, and CO2 sensors for air quality assessment. By merging these independent detection channels, the system cross-validates data to distinguish true life presence from environmental anomalies, reducing false alarms while maintaining high detection accuracy.
Solution Approach 2:
The system implements feedback mechanisms where the radar continuously monitors for breathing patterns and heartbeat movements. When life is detected, the system feedback-loops temperature and CO2 data to assess environmental conditions. This feedback approach allows the system to differentiate between a living subject and environmental conditions by looking for the characteristic rhythmic patterns of respiration and cardiac activity.
3Adaptability or versatility
If a standalone sensor system is used that does not require vehicle installation, then the system can be used in both new and older vehicles, but the system lacks integration with vehicle-specific features and controls
Solution Approach 1:
The patent designs a universal sensor system that functions independently of vehicle-specific features. The radar sensor, temperature sensors, CO2 sensors, GPS, and communication modules form a self-contained unit that can be deployed in any vehicle without requiring integration with the vehicle's electrical system, air conditioning controls, or door lock mechanisms. This universal design enables compatibility with both new and older vehicles while maintaining ease of installation and operation.
4Reliability
If child locks are used to prevent children from opening doors, then safety is improved, but children trapped inside cannot escape and may die from temperature extremes
Solution Approach 1:
The patent introduces an intermediary monitoring system that detects when a child is trapped inside a vehicle with child locks engaged. The radar sensor identifies the child's presence and movement patterns, and when the child becomes immobile (indicating distress or unconsciousness), the system activates emergency communication modules to alert authorities and automatically attempts to unlock doors or notify caregivers, thus mediating between the safety function of child locks and the need for emergency escape.
