Blow stick fire tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire tools, such as blow sticks, lack an efficient mechanism to direct airflow and engage with fuel sources effectively, leading to debris obstruction and inefficient fire stoking.
Innovation Solution
A blow stick apparatus featuring a tube with a second aperture angled inwardly towards a plate, which includes fuel-engaging features and a fluid-diverting region, allowing for fluid diversion and reducing debris entry, with the ability to connect multiple tubes in series for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the second aperture is angled inwardly towards the plate, then fluid diversion and fuel engagement are improved, but debris obstruction increases
Solution Approach 1:
The plate serves as an intermediary element positioned between the second aperture and the fuel source. It intercepts debris particles that would otherwise enter the tube, while still allowing the angled airflow to reach the fuel effectively. The plate's positioning and design enable it to filter harmful debris while maintaining the beneficial angled fluid flow for fire stoking.
2Productivity
If multiple tubes are connected in series, then fluid flow capability is enhanced, but device complexity increases
Solution Approach 1:
The blow stick is divided into multiple separate tube sections that can be connected in series. Each tube functions as an independent fluid passage, and they connect through standardized interfaces. This segmentation allows the device to achieve greater overall fluid flow capability and reach longer distances while maintaining manageable individual component sizes and simplifying manufacturing and assembly.
3Ease of manufacture
If the plate is separate from the tube, then manufacturing flexibility is improved, but device assembly complexity increases
Solution Approach 1:
The plate and tube are manufactured as separate components, allowing each to be optimized independently for its specific function and manufacturing process. The tube can be produced using processes optimized for cylindrical structures, while the plate can be manufactured separately with its specific geometric features. Standardized connection interfaces between the separate components facilitate straightforward assembly despite the additional joining step.
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 apparatus effectively directs airflow with a downward component, reduces debris obstruction, and enhances fuel engagement, improving fire stoking efficiency by ensuring clear fluid flow and effective fuel interaction.
Implementation Method 1
the second aperture is configured to direct fluid in a direction with a downward component
Implementation Method 2
the fluid diverting region diverts fluid emitted from the second aperture, such that the downward component of the direction of the fluid emitted from the second aperture is discontinued

AI summary
An apparatus for stoking a fire may include: at least one tube including a proximal region comprising a first aperture, a distal region comprising a second aperture, and hollow interior region connecting the first aperture and the second aperture, such that the first aperture and the second aperture are in fluid communication with each other; and a plate extending distally from the distal region of the tube, wherein the plate includes at least one fuel-engaging feature and a fluid-diverting region, wherein the fluid diverting region diverts fluid emitted from the second aperture, such that a path of the fluid changes.
