Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire extinguishers are large and heavy, making them difficult to use, and when adapted for vehicles, they often have issues with gas distribution and efficiency in fire fighting, with additional functions like emergency escape mechanisms being cumbersome and inefficient.
Innovation Solution
A compact, lightweight fire extinguisher gas ejector with a piercing device that easily removes the safety member, ensures proper gas jetting, includes an emergency escape mechanism for cutting seat belts and breaking windshields, and features a control valve to prevent gas wastage, ensuring effective fire extinguishing and escape functionality without requiring separate devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a conventional fire extinguisher is made compact and lightweight, then it becomes easier to use and store, but the gas jetting effectiveness and fire fighting capability deteriorate
Solution Approach 1:
The gas cylinder is nested inside the pipe body, with the mouth part of the gas cylinder positioned at the lower end of the pipe body. This nested configuration allows the extinguishing gas to be directed through the pipe body to the jetting port, maintaining fire fighting effectiveness while keeping the overall device compact and lightweight.
Solution Approach 2:
The pipe body acts as an intermediary channel to transport the extinguishing gas from the gas cylinder to the jetting port. This mediator structure ensures proper gas distribution and maintains jetting pressure, resolving the contradiction between compact size and fire fighting effectiveness.
2Device complexity
If the jetting port is positioned at the opposite side of the seal piercing point, then the device structure is simplified, but gas pressure and jetting effectiveness are reduced
Solution Approach 1:
The pipe body is pre-configured with a jetting port at the lower end position before the seal is pierced. When the seal is pierced, the gas flows directly through the pipe body to the pre-positioned jetting port, maintaining pressure and effectiveness while simplifying the overall structure.
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
The solution enables quick and effective fire extinguishing by ensuring proper gas distribution and utilization, while also providing a reliable emergency escape mechanism, enhancing safety and efficiency in vehicle fire scenarios.
Implementation Method 1
a gas cylinder (1) filled with extinguishing gas
Implementation Method 2
A filled gas, which gushed, is guided to inside of a shaft from the inside of the pipe so as to jet the gas from a jetting port

PROBLEM TO BE SOLVED The present invention provides a fire extinguisher gas ejector, which is suitable for use in car. This invention provides a fire extinguisher gas ejector, which removes the safety member easily and quickly, and pierce the seal of the small gas cylinder mounted therewith and jet the gas properly and attempt early fire extinction. This invention comprises the emergency escape mechanism from vehicle, which cuts a seat belt promptly and breaks the windshield surely such as a fire on vehicle and collision, and attempts a prompt escape from vehicle. Moreover, the hammer can be rationally and safely attached to the gas cylinder, and the invention comprises the control valve which prevents a waste of the extinguishing gas and jets the fire extinguishing gas to the origin of a fire surely and accurately in fire fighting. [MEANS FOR SOLVING THE PROBLEM] A fire extinguisher gas ejector having a gas cylinder 1 filled with extinguishing gas and sealed. The fire extinguisher gas ejector has the mouth part, which is removably attached thereto, and the cylinder holder 5 in which the through hole 8 and the nozzle hole 14 are formed therein. The fire extinguisher gas ejector has the piercing pipe 10 with the tip part 19a at one end capable of piercing the seal, and the pipe is slidably mounted and biased upwardly to move. The fire extinguisher gas ejector has the piercing knob 22, which is coupled to the other end of the piercing pipe 10. The fire extinguisher gas ejector has the safety member 27 capable of restricting the operation of the piercing pipe 10. The fire extinguisher gas ejector has the control valve 98, which is arranged movably in the communicating passage between the through hole 8 and the nozzle hole 14. The fire extinguisher gas ejector has the communicating passage, which is arranged to be intermitted by the move of the control valve 98.
