Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional flame mitigation devices for flammable liquid containers often reduce fluid flow rates and cause 'glugging' due to a single chamber design for air intake and fluid output, which can lead to safety hazards and inefficient dispensing.
Innovation Solution
A flame mitigation device with separate fluid and air chambers, featuring fine mesh screens with different aperture sizes in each chamber to improve flow rates and prevent flame ingress, while an anti-glugging mechanism ensures smooth fluid dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single chamber design is used for both air intake and fluid output, then the device structure is simple, but the fluid flow rate is significantly reduced
Solution Approach 1:
The device is divided into separate air chamber and fluid chamber, allowing air and fluid to flow through independent paths. This segmentation eliminates the interference between air intake and fluid output, resolving the contradiction by maintaining simple overall structure while significantly improving fluid flow rate through dedicated separate channels.
2Device complexity
If a single chamber design is used for both air intake and fluid output, then the device structure is simple, but glugging occurs causing splashing and irregular flow
Solution Approach 1:
By separating the air chamber from the fluid chamber, the device eliminates the glugging phenomenon where air bubbles form during pouring. The separate chambers prevent air-liquid interaction that causes splashing and irregular flow, ensuring stable and reliable fluid dispensing while maintaining structural simplicity.
3Object-affected harmful factors
If fine mesh screens are used in a single chamber, then flame mitigation is achieved, but fluid flow rate is reduced
Solution Approach 1:
The fine mesh screen is placed only in the air chamber where it effectively prevents flame ingress, while the fluid chamber maintains larger aperture or no mesh to maximize fluid flow. This spatial segmentation allows the device to achieve both flame mitigation and high fluid flow rate without compromise.
Solution Approach 2:
Different chamber locations have different mesh aperture requirements: the air chamber uses fine mesh for flame safety, while the fluid chamber uses larger openings or no mesh for optimal flow. This local differentiation resolves the contradiction by applying appropriate mesh density to each functional zone.
4Object-affected harmful factors
If smaller aperture mesh is used in the air chamber, then flame protection is enhanced, but air flow is improved
Solution Approach 1:
The air chamber is separated from the fluid chamber, allowing the use of fine mesh screens with small apertures that maximize flame protection without restricting air flow. The independent air path ensures that flame mitigation can be optimized independently from fluid flow requirements.
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 device enhances safety and efficiency by maintaining high fluid flow rates and preventing glugging, thereby reducing the risk of spillage and potential ignition in flammable liquid containers.
Implementation Method 1
barriers that absorb and dissipate the heat of the flame, lowering the temperature below the ignition point
Implementation Method 2
The air chamber includes one or more fine mesh screens with smaller apertures than those in the fluid chamber to increase a pressure differential, improving air flow
Implementation Method 3
As fluid pools in cup-like portion in the chamber, it stops further fluid from exiting and acts as a further flame barrier

AI summary
A flame mitigation device for flammable liquid containers includes a cylindrical body with vertical fine mesh screens in the air chamber and horizontal fine mesh screens in the fluid chamber. The air chamber and fluid chamber are separated so fluid and air do not mix or interfere with each other whilst fluid is being poured from the bottle, through the flame mitigation device. When attached to a flammable liquid container, the device provides improved fluid flow and prevents flame propagation, ensuring safe storage and handling of flammable liquids.
