Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional fire extinguishing agents are ineffective for Class D fires, particularly magnesium fires, as they can fuel the fire or pose toxicity risks, and existing solutions fail to simultaneously extinguish multiple classes of fires while being environmentally friendly and non-toxic.

Innovation Solution

A fire extinguishing composition comprising Aloe vera extract, xanthan gum, and other bio-based components that form a gel or flowable liquid, providing a halogen-free, sugar alcohol-free, and non-toxic solution capable of extinguishing Class D fires and other classes, including Class A, B, and K fires, by using a botanical material and polysaccharides to enhance heat capacity and emulsion stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional fire extinguishing agents are used on Class D fires, then the fire can be suppressed, but the agents can fuel the fire or pose toxicity risks

Engineering Contradiction:

Improvefire suppression effectivenessVSAvoidtoxicity and fire-fueling risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters by using botanically-derived ingredients with specific properties (high heat capacity, low reactivity) to eliminate toxicity and fire-fueling risks while maintaining suppression effectiveness

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite extinguishing composition combining multiple botanical ingredients (e.g., Aloe vera, acemannan) with complementary properties to achieve both safety and effectiveness in suppressing Class D fires

Inventive Principle:

Principle #40Composite materials

2Reliability

If a single fire extinguishing composition is designed for Class D fires, then magnesium fires can be extinguished, but it may not be effective for other fire classes

Engineering Contradiction:

ImproveClass D fire suppressionVSAvoidmulti-class fire coverage

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent designs a multi-functional composition that can suppress multiple fire classes (A, B, C, D, and K) through a combination of ingredients that address different combustion mechanisms while maintaining botanical safety

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent tailors the composition's properties to address specific fire class requirements: high heat capacity for Class D metals, emulsion stability for Class B liquids, and cooling efficiency for Class A combustibles, all within a single botanical formulation

Inventive Principle:

Principle #3Local quality

3Reliability

If halogen-containing agents are used for fire suppression, then fire extinguishing performance is improved, but environmental harm and toxicity increase

Engineering Contradiction:

Improvefire extinguishing performanceVSAvoidenvironmental harm

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent eliminates harmful halogenated compounds and replaces them with beneficial botanical ingredients that provide fire suppression through natural mechanisms (cooling, smothering, chemical inhibition) without environmental damage

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent uses botanically-derived ingredients that create a safe, non-reactive extinguishing environment that suppresses fire without introducing harmful chemicals into the atmosphere or surrounding environment

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

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 composition effectively extinguishes and cools magnesium fires, rapidly reducing the temperature of extinguished materials to safe levels, and can be used across multiple fire classes, ensuring safety for humans and the environment.

Implementation Method 1

The compositions can be used to extinguish fires by contacting the fire with the compositions, thereby cooling and/or extinguishing the fire

Methodology Applied

Scientific EffectHeat absorption: Absorption (EM radiation)

Implementation Method 2

rapidly reducing the temperature of extinguished materials to safe levels

Methodology Applied

Scientific EffectThermal conduction: Conduction (thermal)

AI summary

Systems and compositions for suppressing and extinguishing several classes of fire, e.g. Class D, fires are disclosed. The composition includes some form of powdered Aloe vera, a bio-surfactant, a thickening agent, and a diol. The composition may be mixed with paint to coat a structure thus protecting the structure from fire. The composition may also be mixed with epoxy resin for coating a structure also for fire protection. The composition may also be in the form of a gel in canisters for extinguishing fire.
