Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire extinguishing devices for ranges do not integrate a fire extinguisher within the appliance to automatically extinguish fires, and lack remote monitoring capabilities for cooking safety.
Innovation Solution
A range with integrated oven and burners, temperature sensors, a fire extinguisher containing fire retardant, and strategically placed nozzles that automatically spray the retardant when excessive temperature is detected, along with wireless communication for remote monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fire extinguisher is integrated into the range, then fire extinguishing capability is improved, but device complexity increases
Solution Approach 1:
The fire extinguishing system is merged with the range by integrating the fire extinguisher, temperature sensors, and nozzle system into the range structure. The control circuit is integrated to receive signals from temperature sensors and automatically actuate the fire extinguisher, combining fire detection and suppression functions within the existing range appliance.
Solution Approach 2:
The range is enhanced with multi-functionality by adding fire extinguishing capabilities to its cooking functions. The system can operate in normal cooking mode or automatically switch to fire suppression mode when excessive temperature is detected, making the range capable of both cooking and fire safety functions.
2Reliability
If temperature sensors are integrated into the range, then fire detection capability is improved, but device complexity increases
Solution Approach 1:
The range performs self-monitoring for fire conditions through integrated temperature sensors that continuously detect temperature at the burners and oven. The control circuit automatically processes sensor signals and triggers the fire extinguishing system without external intervention, enabling the range to self-detect and self-response to fire hazards.
3Reliability
If multiple nozzles are strategically distributed around the range, then fire retardant coverage is improved, but device complexity increases
Solution Approach 1:
The fire suppression system is segmented into multiple nozzles distributed at different locations around the range, including near burners and within the oven. Each nozzle is connected to the fire extinguisher through fluid communication, allowing segmented coverage of different fire zones within the range for comprehensive fire suppression.
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 automatic fire extinguishing and remote monitoring, ensuring quick fire suppression and kitchen safety while preventing heat damage to the range.
Implementation Method 1
An oven temperature sensor is integrated into the range and a burner temperature sensor is integrated into the range. The fire extinguisher is actuated when either of the burner temperature sensor or the oven temperature sensor senses a temperature that exceeds a pre-determined temperature.
Implementation Method 2
A fire extinguisher is integrated into the range and the fire extinguisher contains a fire retardant. Each of nozzles is in fluid communication with the fire extinguisher thereby facilitating each of the nozzles to spray the fire retardant when the fire extinguisher is actuated to extinguish a fire that is burning in or on the range.
