Fire Extinguishing Gas Spray Device With Segmented Actuator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire extinguishers are cumbersome, difficult to operate, and often waste extinguishing gas due to complex mechanisms and accidental activation, leading to inefficient fire suppression and delayed response, especially in emergencies like nighttime or power failures.
Innovation Solution
A compact, user-friendly jetting apparatus with a control valve system that prevents gas wastage by storing and accurately directing extinguishing gas to the fire source, featuring a piercing member, control valve, and integrated alarm and lighting systems for easy operation and quick identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional fire extinguishers are made large and heavy to contain sufficient extinguishing gas, then the extinguishing capacity is improved, but the ease of operation deteriorates
Solution Approach 1:
The fire extinguishing system is divided into two separate components: a portable actuator unit that the user carries and operates, and a stationary gas cylinder that remains fixed. This segmentation allows the heavy gas storage function to be separated from the user's burden, enabling easy operation while maintaining sufficient extinguishing gas capacity.
Solution Approach 2:
A valve mechanism acts as an intermediary between the portable actuator and the gas cylinder. When the user activates the actuator, it triggers the valve to open, allowing the extinguishing gas to flow from the cylinder through a hose to the discharge point. This intermediary mechanism enables the transfer of gas without requiring the user to handle the heavy cylinder.
2Measurement precision
If complex mechanisms are used to control gas release, then the precision of gas delivery is improved, but the device complexity increases
Solution Approach 1:
The complex control and precision delivery mechanisms are extracted from the portable unit and placed in the stationary system. The portable actuator contains only simple triggering components, while the valve and flow control mechanisms reside in the fixed gas cylinder assembly, reducing the complexity of the user-carried device.
Solution Approach 2:
The system uses the pressure of the stored extinguishing gas itself to drive the flow and delivery process. The high-pressure gas automatically flows through the valve and hose when released, eliminating the need for complex pumps, motors, or active control systems in the portable unit.
3Reliability
If the piercing pipe is slightly moved during operation, then the reliability of sealing is improved, but the time required to pierce the sealing plate increases
Solution Approach 1:
The piercing pipe is pre-positioned and rigidly fixed in the stationary gas cylinder assembly before operation. The sealing plate is also pre-positioned at a fixed location. When the system is activated, the piercing action occurs immediately without any movement or adjustment of the piercing pipe during the process, ensuring both rapid piercing and reliable sealing.
4Ease of operation
If the jetting hole is not properly oriented toward the fire source, then the ease of operation is improved, but the loss of extinguishing gas increases
Solution Approach 1:
The system provides three-dimensional orientation capability for the jetting hole through the flexible hose connection. The hose can be directed toward the fire source from any angle or position, allowing the discharge point to be oriented precisely toward the fire while the user maintains a comfortable and safe operating position. This spatial flexibility ensures both easy operation and efficient gas delivery.
