Fire Extinguishing Tube Pressure Sensor for Early Fire Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire prevention systems are ineffective in predicting and preventing fires, as they only react after the fire has occurred, and portable fire extinguishers are difficult to locate and use during a fire, posing risks to users.
Innovation Solution
A fire extinguishing device with a fire prediction function that senses early signs of a fire through a pressure sensor in a fire extinguishing tube container, measuring internal pressure to predict and alert external systems, and automatically emit extinguishing substances when exposed to fire or heat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing fire prevention systems use temperature and smoke sensors to detect fires after they occur, then fire suppression can be activated, but the system cannot predict or prevent fires before they occur
Solution Approach 1:
The patent applies preliminary action by monitoring internal pressure changes in the fire extinguishing tube container before a fire occurs. The pressure sensor detects subtle pressure variations caused by heat transfer from developing fires, enabling the system to predict fire risk and alert users before actual fire occurrence, thus acting in advance rather than reacting after fire starts
Solution Approach 2:
The patent replaces the conventional thermal and optical detection methods with a pressure-based detection system. Instead of using temperature sensors that react to established fire conditions, the system uses a pressure sensor to detect mechanical changes in the container caused by early heat transfer, substituting a mechanical measurement approach for traditional fire detection methods
2Ease of operation
If portable fire extinguishers are placed in common areas, then they are readily accessible, but users must approach the ignition point which exposes them to noxious gas and high-temperature heat
Solution Approach 1:
The patent applies self-service by designing an automatically activating fire extinguishing system. The fire extinguishing tube container is equipped with a pressure sensor and alert system that automatically detects fire risk, monitors pressure changes, and can activate the extinguishing agent without requiring user intervention or approach to the ignition point, thus eliminating exposure to harmful factors while maintaining accessibility
Solution Approach 2:
The patent introduces an intermediary alert system that communicates fire risk between the detection point and users remotely. The alert device serves as an intermediary that warns users of fire conditions without requiring them to physically approach the ignition point, mediating between the fire hazard and human safety
3Reliability
If fire extinguishing tube containers are sealed to prevent premature discharge, then fire safety is maintained, but early signs of fire cannot be detected through pressure changes
Solution Approach 1:
The patent replaces direct thermal or visual inspection methods with a pressure-based measurement system. By monitoring internal pressure changes in the sealed container, the system can indirectly detect early fire signs through heat transfer effects without compromising the seal, substituting a sensitive mechanical measurement for direct observation methods
Solution Approach 2:
The patent uses pressure as an intermediary parameter to detect fire conditions. Instead of directly measuring temperature or observing smoke, the system uses pressure changes in the sealed container as an intermediate indicator that reflects early heat transfer from developing fires, enabling indirect detection while maintaining seal integrity
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
Enables predictive maintenance and early fire prevention by sensing fire risks, reducing the risk of injuries and property damage by automatically reacting to fire signs before they escalate.
Implementation Method 1
a fire pre-sensor coupled to a side of the fire extinguishing tube container and sensing a surrounding early sign of a fire by measuring an internal pressure of the fire extinguishing tube container
Implementation Method 2
When the surrounding fire of the fire extinguishing tube container directly transfers to the outer surface of the container or the surrounding heat indirectly transfers to the outer surface of the container, the fire extinguishing substance may be emitted through a rupture hole

AI summary
The present disclosure relates to a fire extinguishing device with a fire prediction function. The fire extinguishing device with a fire prediction function includes: a fire extinguishing tube container including a fire extinguishing substance therein, and automatically emitting the fire extinguishing substance when being exposed to surrounding fire or heat; a fire pre-sensor coupled to a side of the fire extinguishing tube container and sensing a surrounding early sign of a fire by measuring an internal pressure of the fire extinguishing tube container; and a fire monitor connected with the fire pre-sensor and generating monitoring information while collecting an internal state of the fire extinguishing tube container and external environmental information. Accordingly, the present disclosure can predict and sense a fire that occurs around by measuring the internal pressure of the fire extinguishing tube container, and can provide prediction information about a fire and take an initial reaction by providing an alert to the outside through a network.
