Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flame propelling devices often rely on pressurized vessels with petroleum-based flammable liquids and ignition sources, lacking a non-pressurized vessel configuration for pumping an alcohol solution effectively.
Innovation Solution
A portable flame propelling device featuring a non-pressurized vessel with a pumping unit and igniter, where a handle-attached nozzle propels alcohol solution through a pumping mechanism and ignites it using a piezoelectric element or similar ignition source, allowing controlled flame emission to deter animal attacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressurized vessel with petroleum-based flammable liquid is used, then the flame propelling device can achieve reliable ignition and flame propagation, but the device becomes more complex and less safe due to pressure containment requirements
Solution Approach 1:
The patent changes the physical state parameter from pressurized liquid to non-pressurized liquid, and changes the chemical composition from petroleum-based to alcohol-based. This allows the system to eliminate pressure containment structures while maintaining flammability and ignition reliability through the use of a pump to deliver alcohol solution to the ignition source.
2Device complexity
If a non-pressurized vessel with alcohol solution is used, then the device safety and simplicity improve, but the ability to propel flame effectively deteriorates without adequate pumping mechanism
Solution Approach 1:
The patent employs a pumping mechanism (hydraulic principle) to deliver alcohol solution from the non-pressurized vessel through a tube to the ignition source. The pump creates the necessary fluid flow and pressure temporarily during operation, allowing effective flame propulsion without requiring a pressurized vessel structure. The pump is activated by a spring mechanism that compresses and releases to propel the alcohol solution.
3Reliability
If a piezoelectric ignition source is used, then the ignition reliability and portability improve, but the device complexity increases due to electrical component integration
Solution Approach 1:
The piezoelectric ignition system is designed to be self-activating through mechanical compression. When the user compresses the spring mechanism, it simultaneously propels the alcohol solution through the pump and triggers the piezoelectric element to generate a spark. This self-service design eliminates the need for separate electrical switches or control circuits, reducing overall device complexity while maintaining reliable ignition.

AI summary
A portable flame propelling device for deterring an attack by an animal includes a vessel, which has an opening positioned in a top thereof for positioning of a flammable liquid therein. A handle engaged to the vessel and extending from the opening can be grasped in a hand of a user. A nozzle is engaged to the handle and extends therefrom. A pumping unit operationally engaged to and in fluidic communication with the nozzle and the vessel propels the flammable liquid from the vessel through the nozzle. An igniter engaged to the handle proximate to the nozzle ignites the flammable liquid. An actuator engaged to the handle is operationally engaged to the pumping unit and the igniter. The actuator can be engaged by a digit of the hand of the user to selectively actuate the pumping unit and the igniter so that a flame is propelled from the nozzle.
