Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for preventing forest fire spread are inadequate due to the challenges of accessing and extinguishing fires in rugged terrain, inefficiencies in water supply, and the unsuitability of conventional fire extinguishers for large-scale forest fires, leading to property losses and safety concerns.
Innovation Solution
A forest fire spread prevention device comprising a thermoplastic plastic tape outer skin member with a high melting point and a cylindrical inner skin member made of a material with a lower melting point, filled with water, which automatically ejects water through holes formed by melting when exposed to heat, creating a barrier to stop fire spread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fire extinguishers are used for forest fires, then the structure is complicated and difficult to manipulate, but the effectiveness is insufficient for large-scale forest fires
Solution Approach 1:
The fire prevention device is divided into multiple segments: an outer skin member made of heat-resistant material and an inner skin member made of low-melting-point material. This segmentation allows the device to function automatically when exposed to fire heat, with the inner member melting to release water without requiring manual operation or complex mechanisms.
Solution Approach 2:
The device performs fire prevention automatically through self-service mechanism. When the outer skin member is exposed to fire heat, it transfers heat to the inner skin member, causing the inner member to melt and release water automatically. This eliminates the need for manual manipulation or complex control systems.
2Productivity
If water is sprayed on fire sites directly, then fire extinguishing is effective, but water supply is challenging in rugged terrain and water is wasted severely
Solution Approach 1:
Water is pre-stored in the inner skin member during normal conditions. When fire occurs, the pre-stored water is immediately released through the melting inner member, eliminating the need for real-time water supply operations and ensuring effective fire extinguishing without water waste.
Solution Approach 2:
The device uses hydraulic principles by storing water under pressure in the inner skin member. When the inner member melts due to heat transfer from the outer member, the stored water is forced out through pressure differential, achieving effective fire suppression without requiring external water supply systems.
3Productivity
If fire trucks are used in mountainous terrain, then fire extinguishing capability is provided, but the vehicle structure makes it difficult to enter the fire site
Solution Approach 1:
The fire prevention device is designed as a simple, inexpensive unit that can be easily deployed in rugged terrain where fire trucks cannot access. The device uses basic materials (outer and inner skin members with different thermal properties) to provide effective fire prevention without requiring complex vehicle infrastructure.
Solution Approach 2:
The invention replaces the mechanical fire truck system with a thermal-based passive fire prevention device. Instead of using vehicles with complex mechanical structures, the device uses heat transfer principles to automatically trigger water release, making it suitable for remote mountainous areas without requiring vehicle access.
4Reliability
If a fire-arresting line is established by cutting down forests, then fire spread is stopped, but the process is time-consuming and labor-intensive
Solution Approach 1:
The device provides automatic fire spread prevention through self-service mechanism. When exposed to fire heat, the outer skin member transfers heat to the inner skin member, which melts automatically to release water. This eliminates the need for manual creation of fire lines and provides immediate protection.
Solution Approach 2:
The device utilizes phase transition of the inner skin member material from solid to liquid at a specific melting point. This phase change automatically triggers water release when fire heat is detected, providing rapid and reliable fire spread prevention without requiring time-consuming manual intervention or forest cutting.
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
Effectively blocks forest fire spread, reduces property losses, and minimizes the risk of human injury by automatically extinguishing fires without the need for manual intervention, using a device that can be easily installed and replenished with water.
Implementation Method 1
when the fire approaches the outer skin member to heat the same, the heat is transferred to the inner skin member, and the inner skin member having a relatively low melting point is melted first to form holes
Implementation Method 2
the inner skin member having a relatively low melting point is melted first to form holes
Implementation Method 3
the water for fire extinguishing is ejected to an outside through the holes formed by the melting and gaps provided in a mesh texture of the outer skin member
Implementation Method 4
the water for fire extinguishing is ejected to an outside through the holes formed by the melting and gaps provided in a mesh texture of the outer skin member to extinguish the surrounding fire and cool the outer skin member

AI summary
A forest fire spread prevention device as an automatic fire extinguishing device for a forest fire may suppress an occurrence of property loss and loss of lives by blocking the forest fire in the middle so that it does not spread to nearby private houses when a forest fire occurs. The forest fire spread prevention device can include a burlap bag-shaped outer skin member which is woven with a thermoplastic plastic tape having a melting point of 160 to 280° C. as a weft and a warp; and an inner skin member of a cylindrical container which is accommodated in the outer skin member and formed in a film shape prepared by extruding a thermoplastic plastic material having a thickness of 15 to 50 microns and a melting point of 110 to 130° C. in a cylindrical shape, and has an inner space filled with water.
