Solution Overview
Problem
Existing vehicle temperature sensing and warning systems for unattended children or pets lack comprehensive and user-friendly solutions for monitoring and ensuring safety, particularly in terms of temperature and proximity-based alerts, leading to potential risks of neglect or accidental locking.
Innovation Solution
A mobile alert security system comprising self-contained slave monitoring units attached to individuals or pets and a master control unit, utilizing integrated temperature sensors, proximity sensors, alarm circuits, and two-way communication, to provide alerts and ensure safe exit protocols when safety parameters are exceeded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple vehicle control systems are activated (windows, doors, sun roofs, alarm) once predetermined temperature is reached, then safety protection is improved, but device complexity increases
Solution Approach 1:
The system divides the monitoring function into independent sensor modules distributed throughout the vehicle interior. Each module independently monitors temperature and transmits data to a central processor, allowing the system to scale from simple temperature monitoring to complex multi-system control by adding or activating specific sensor modules as needed.
Solution Approach 2:
The sensor modules are designed with universal functionality to monitor multiple parameters (temperature, humidity, air quality) and trigger multiple response systems (windows, doors, alarms, HVAC). This multi-functional design reduces overall system complexity by using standardized components rather than dedicated sensors and actuators for each function.
2Measurement precision
If temperature sensors are positioned in different locations throughout the vehicle, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The vehicle interior is divided into multiple monitoring zones with sensor modules positioned in each zone. Each module independently measures temperature in its local area and transmits readings to the central processor, which synthesizes data from all zones to provide comprehensive temperature mapping and accurate detection of hot spots.
Solution Approach 2:
Each sensor module is self-contained with its own power source, processing capability, and communication interface. The modules autonomously monitor their local environment and transmit data without requiring complex wiring or centralized control for basic operation, reducing installation and system management complexity.

AI summary
A mobile personal alarm and warning system for monitoring temperature around the designated user integrated with a vehicle access and warning controls. The system utilizes controls and actuation mobile self-contained modules that monitor the ambient temperature around the designated user and transmits a warning activation signal to the mobile control unit carried by the primary user as an alert condition. Proximity sensor provisions are provided to assure response range between the modules as well as enabling two-way radio communication protocols.
