Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fire detection systems rely on optical cameras that require fires to reach a significant size for detection, lack accurate locationing, and are limited by atmospheric conditions and line-of-sight communication, while carbon monoxide detection is hindered by the need for precise threshold measurements and rapid communication of dangerous levels.
Innovation Solution
Development of fire and carbon monoxide detection devices equipped with processors and transceivers that use Lightweight Machine-to-Machine (LwM2M) protocols to receive sensor data, determine threshold criteria satisfaction, generate warning messages, and send alerts via wireless communication networks, including cellular and IoT networks, for early and accurate detection and response.

Engineering Contradiction Analysis
1Measurement precision
If optical cameras are used for fire detection, then detection capability is provided, but detection is limited to fires of significant size and intensity
Solution Approach 1:
The patent replaces optical camera-based detection with CO sensor-based detection. Instead of using visible light cameras that require fires to reach significant size, the system uses carbon monoxide sensors to detect the presence of CO gas, which is produced during incomplete combustion. This substitution enables detection of fires at much earlier stages, before they reach visible sizes, thereby improving detection sensitivity while eliminating the minimum fire size requirement.
2Loss of information
If conventional sensors are used for fire detection, then detection is provided, but accurate coordinate location is not obtained
Solution Approach 1:
The patent combines CO detection functionality with GPS location capabilities into an integrated detection device. The system merges the CO sensor that detects fire presence with a GPS receiver that provides accurate coordinate information. This combination ensures that whenever a fire is detected, the system simultaneously captures and transmits the precise location data, eliminating the loss of location information and providing accurate coordinate accuracy for emergency response.
3Reliability
If line-of-sight communication is used, then communication capability is provided, but communication is limited by atmospheric conditions
Solution Approach 1:
The patent implements multiple communication interfaces including cellular modem and satellite communication capabilities in addition to wireless communication. This multi-functional communication system allows the device to adapt to different environmental conditions: using cellular networks when available, switching to satellite communication when cellular coverage is unavailable, and utilizing wireless communication for local data transfer. This universal communication approach ensures reliable operation across diverse environments without being limited by atmospheric conditions or line-of-sight requirements.
4Measurement precision
If CO detection requires precise threshold measurements, then accurate CO level detection is achieved, but rapid communication of dangerous levels is hindered
Solution Approach 1:
The patent pre-configures threshold values for CO concentration levels and establishes communication protocols in advance. The system continuously monitors CO levels and automatically compares readings against pre-set thresholds. When dangerous levels are detected, the pre-configured communication system immediately transmits alerts without requiring real-time threshold calculation or complex decision-making processes. This preliminary configuration enables both precise threshold measurement and rapid communication of dangerous CO levels.
