Solution Overview

Problem

Conventional methods for combating wildfires are often ineffective in protecting structures at the urban-wildland interface, leading to significant destruction and economic losses, as they struggle to prevent wildfires from spreading to residential areas.

Innovation Solution

A fire retardant distribution system that includes a self-contained, remotely activatable network of pipes and nozzles spraying fire retardant on structures and surrounding landscapes, using a combination of water and fire retardant tanks, and a control system for strategic deployment based on real-time data and historical fire patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional wildfire fighting methods are used, then firefighters can directly combat the fire, but they cannot effectively prevent wildfire from destroying structures at the urban-wildland interface

Engineering Contradiction:

Improveeffectiveness of wildfire protectionVSAvoidability to protect structures

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system applies fire retardant to structures and surrounding vegetation in advance of the wildfire's arrival, creating a protective barrier before the fire reaches the urban-wildland interface. This preliminary treatment prevents the fire from igniting structures and reduces its intensity as it approaches residential areas.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Fire retardant serves as an intermediary substance between the wildfire and the structures it threatens. The retardant chemically treats the fuel sources (vegetation and structure surfaces) to reduce their combustibility, acting as a buffer that interrupts the fire's progression into residential zones.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If fire retardant is applied to structures and surrounding areas, then fire protection effectiveness increases, but system complexity and deployment requirements increase

Engineering Contradiction:

Improvefire resistance of structuresVSAvoiddistribution system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The fire retardant distribution system is divided into multiple independent spray units positioned at different locations around the structure. Each unit can be independently activated and controlled, allowing selective application to different zones based on fire threat levels. This segmentation simplifies the overall system architecture and enables modular deployment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The distribution system is designed to serve multiple functions: it can apply fire retardant to structures, treat surrounding vegetation, and adapt to different fire scenarios. The same infrastructure supports various application methods and can be integrated with existing fire safety systems, reducing overall complexity through multi-purpose design.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If real-time fire monitoring and strategic deployment are implemented, then fire direction control improves, but system operational complexity increases

Engineering Contradiction:

Improvefire direction control capabilityVSAvoidsystem control complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system incorporates real-time fire monitoring that detects fire location, intensity, and direction of spread. This feedback information is continuously fed to the control system, which automatically adjusts spray unit activation and fire retardant application rates to counteract the fire's progression and redirect it away from protected structures.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system transitions from static, pre-programmed fire protection to dynamic, real-time adaptation. Spray units can be selectively activated or deactivated based on changing fire conditions, and application parameters are continuously adjusted to optimize fire direction control while simplifying operator intervention through automated decision-making algorithms.

Inventive Principle:

Principle #15Dynamics

AI summary

A fire retardant delivery system for use with a source of carrier for protection from wildfire is provided. The system includes a retardant tank for storing a fire retardant. The retardant tank is in fluid communication with the source of carrier. A metering valve is constructed and arranged to meter a flow of fire retardant injected into the carrier discharged from the source of carrier to maintain a predetermined proportion of fire retardant to carrier, thereby creating a fire retardant and carrier mixture. At least one distribution nozzle is configured to deliver the fire retardant and carrier mixture to a desired area.
