Modular Fire Barrier Panels for Wildfire Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire barriers for open area fires are often ineffective, expensive, difficult to create, and not easily adaptable for remote or rugged terrain, as they can be jumped by strong winds and require significant resources and manpower.
Innovation Solution
A portable, adjustable, and flexible fire barrier system comprising a vertically orientable sheet of fire-resistant material, such as mineral wool, supported above the ground by a vertical structure, which can be connected to extend its length or height, and includes a wetting agent for enhanced fire resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fire break is created by clearing land with bulldozers and hand tools, then a barrier strip is formed to prevent fire spread, but the process requires large teams and expensive equipment that are difficult to deploy in remote or rugged terrain
Solution Approach 1:
The fire barrier system divides the barrier into modular panels that can be individually transported and assembled. Each panel is a self-contained unit with standardized dimensions and connection mechanisms, allowing the barrier to be constructed in segments rather than requiring large-scale land clearing operations.
Solution Approach 2:
The patent introduces panels as an intermediary element between the fire and the protected area. These panels serve as a portable substitute for traditional fire breaks, providing fire resistance without requiring bulldozing equipment or large teams of workers to clear land.
2Reliability
If a traditional fire break is used, then vegetative fuel is removed to create a barrier, but strong winds can carry embers across the break line and jump the barrier
Solution Approach 1:
The fire barrier panels utilize composite construction with multiple layers including fire-resistant materials such as gypsum board, plywood, and insulation layers. This composite structure creates a more robust barrier that can resist wind-blown embers better than a simple cleared strip of land.
Solution Approach 2:
The patent transitions from a two-dimensional fire break (a flat cleared strip on the ground) to a three-dimensional barrier system with vertical panels standing upright. This vertical dimension adds height and structural integrity, making it more difficult for wind-blown embers to overcome the barrier.
3Reliability
If complete dousing of a large open area fire is attempted, then the fire can be extinguished, but it requires extensive resources and is difficult when the fire reaches certain size and scale
Solution Approach 1:
The fire barrier system extracts the fire containment function from the traditional approach of applying large quantities of water to douse the entire fire. Instead, it creates a physical barrier that isolates and contains the fire in a specific area, requiring fewer resources while achieving fire control.
Solution Approach 2:
The barrier system allows the fire to continue burning in a controlled, contained area rather than attempting to extinguish it completely. This converts the potentially harmful uncontrolled fire into a managed situation where the fire's energy is contained and can be monitored with fewer resources.
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 system effectively prevents the spread of open area fires by blocking embers and fuel, is less likely to be jumped by strong winds, and can be quickly and cost-effectively deployed in challenging terrains, reducing the risk of property damage and loss of life.

AI summary
A fire barrier system includes a fire-resisting sheet that has a fire-resisting layer and a support layer. In one version, the fire-resisting layer comprises mineral wool. A support structure is adapted to support the fire-resisting sheet above the ground so that the fire barrier system can be positioned in proximity to a fire to help prevent the spread of the fire across the fire barrier system. A sheet connecting mechanism can also be provided to connect the fire-resisting sheet to a second fire-resisting sheet. The fire barrier system is particularly useful as a fire break in an open area fire.
