Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wildfire fighting methods are inadequate for urban areas, as they are reactive and often ineffective, pose safety risks to firefighters, and contribute to environmental pollution, particularly in the Wildfire Urban Interface (WUI) regions, where climate change and viral pandemics exacerbate the challenges.
Innovation Solution
Development of environmentally-clean, aqueous-based wildfire inhibiting biochemical compositions that form thin alkali metal salt crystalline coatings on combustible surfaces to proactively inhibit fire ignition and smoke production, using alkali metal salts derived from non-polymerized saturated carboxylic acids, which are safe for the environment and living organisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wildfire fighting methods (aerial water dropping, chemical retardant dropping, bulldozing) are used, then fire suppression capability is improved, but safety risks to firefighters increase and environmental pollution worsens
Solution Approach 1:
The invention changes the chemical composition parameters of fire retardants from conventional phosphorous-based chemicals to environmentally-safe potassium mineral salts derived from non-polymerized saturated carboxylic acids. This parameter change maintains fire suppression effectiveness while eliminating toxic effects on firefighters and the environment.
Solution Approach 2:
The invention converts the harmful effect of fire into a beneficial process by using controlled combustion of the biochemical composition to create a protective char layer on combustible surfaces. This char layer prevents further fire spread while the composition itself decomposes into harmless substances, turning the destructive fire energy into a protective mechanism.
2Productivity
If reactive wildfire fighting methods are used, then immediate fire suppression is achieved, but effectiveness in urban areas decreases and resource consumption increases
Solution Approach 1:
The invention applies fire-inhibiting biochemical compositions to combustible surfaces in advance of potential wildfire threats, creating a protective barrier before fire contact. This preliminary treatment transforms the strategy from reactive suppression to proactive protection, particularly valuable in urban-wildland interface areas where pre-treating structures and vegetation provides immediate resistance when fire approaches.
3Reliability
If phosphorous-based chemical retardants are used, then fire spread inhibition is improved, but environmental pollution and toxicity increase
Solution Approach 1:
The invention fundamentally changes the chemical identity of fire retardants from phosphorous-based compounds (MAP, DAP) to potassium mineral salts of non-polymerized saturated carboxylic acids. This parameter substitution eliminates the toxic and environmentally-persistent nature of phosphorous chemicals while maintaining fire spread inhibition through alternative mechanisms including heat absorption and char formation.
Solution Approach 2:
The biochemical composition is designed to be temporarily effective, decomposing into harmless natural substances (carbon dioxide, water, mineral salts) after performing its fire protection function. This disposable approach eliminates long-term environmental contamination while providing sufficient protection during the critical fire exposure period.

AI summary
Environmentally-clean wildfire inhibitor liquid biochemical solutions produced from an aqueous mixture of alkali metal salt derived from a non-polymerized saturated carboxylic acid, and dissolved in water along with a dispersing and coalescing agent, realized as an ester of a non-polymerized saturated carboxylic acid, and dissolved in the water to provide a liquid fire inhibitor solution that can be sprayed on combustible surfaces to form thin alkali metal salt crystalline coatings on the combustible surfaces when and as water molecules in the liquid fire inhibitor evaporate to the environment during drying operations, to inhibit fire ignition, flame spread and smoke development.
