Stovetop Fire Suppression Chute for Unobstructed Burner Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stovetop fire suppression devices are bulky, obstructive, and inefficient in directing fire suppressant powder, making them difficult to install and ineffective in quickly extinguishing stovetop fires.
Innovation Solution
A stovetop fire suppression system with a base member and a chute member that can pivot between storage and dispensing positions, allowing selective release of fire suppressant powder onto individual burners using actuation members, and featuring a dual pivot/hinge system for precise powder distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If fire suppression devices are made large and bulky to store sufficient suppressant powder, then the quantity of suppressant powder is improved, but the device obstructs access to cooking surfaces and is difficult to install
Solution Approach 1:
The fire suppression device is divided into multiple segments: a base member mounted on the wall, a movable chute member that can pivot between storage and dispensing positions, and separate actuation members. This segmentation allows the suppressant powder to be stored in a compact base while the chute can be positioned only when needed, eliminating obstruction during normal cooking while maintaining sufficient powder capacity.
Solution Approach 2:
The chute member is designed to be dynamic rather than static, pivoting between a storage position (clear of the cooking surface) and a dispensing position (directed at the burner). This dynamic positioning resolves the contradiction by allowing the device to maintain both compact storage and effective powder delivery without permanently obstructing the cooking area.
2Quantity of substance
If fire suppression devices are made large and bulky to store sufficient suppressant powder, then the quantity of suppressant powder is improved, but the device is difficult to install
Solution Approach 1:
The device is segmented into a wall-mounted base member and a separate movable chute member connected via hinges. This allows the base to be installed independently on the wall, while the chute can be attached and positioned separately, simplifying the overall installation process while maintaining sufficient powder storage capacity in the base.
Solution Approach 2:
The chute member is positioned in three-dimensional space, pivoting from a horizontal storage position to a vertical dispensing position. This spatial arrangement allows the device to maintain a compact footprint on the wall while providing adequate powder storage and delivery capability, making installation more manageable.
3Device complexity
If fire suppression devices use simple storage structures, then the device complexity is reduced, but the precision in directing suppressant powder to specific burners is insufficient
Solution Approach 1:
The chute member dynamically pivots to different positions based on which burner requires suppression. This simple yet effective mechanical movement allows precise targeting of suppressant powder to either the first or second burner without requiring complex electronic controls or multiple chutes, maintaining low device complexity while achieving high precision in powder distribution.
Solution Approach 2:
The chute member acts as an intermediary between the suppressant powder storage and the target burners. By pivoting this single chute to different positions, the system achieves precise powder delivery to specific burners without the complexity of having separate delivery mechanisms for each burner.
4Speed
If fire suppression devices are designed to quickly extinguish fires, then the speed of fire suppression is improved, but the device may obstruct the cooking surface
Solution Approach 1:
The chute member dynamically positions itself only when fire suppression is needed, pivoting from a clear storage position to a targeted dispensing position. This allows the device to achieve rapid fire suppression by directing powder precisely at the fire source while remaining clear of the cooking surface during normal operation, thus eliminating obstruction.

AI summary
A stovetop fire suppression system for selectively releasing a fire suppressant powder onto a stovetop first or second burner. The stovetop fire suppression system includes a base member and a chute member secured to the base member at opposed first and second ends of the base member. The chute member is movable between a storage position and a dispensing position. The suppression system further includes a first actuating member disposed at the base section first end and a second actuating member disposed at the base section second end. In response to actuation of the first actuating member, the chute member is movable the dispensing position to release the fire suppressant powder onto the first burner, and in response to actuation of the second actuating member, the chute member moves to the dispensing position to release the fire suppressant powder onto the second burner.
