Solution Overview

Problem

Current methods for forest fire control and prevention are inefficient, environmentally unsafe, and pose risks to firefighters and wildlife, as they rely on helicopters and air tankers that are costly, time-consuming, and ineffective in extinguishing large, frequent, and widespread forest fires.

Innovation Solution

A system comprising forest fire detection devices and a spray device that uses sensors to detect fires, collect data, alert authorities, and activate a water spray mechanism via a mobile app or control room, powered by solar panels and energy storage, allowing targeted and efficient water application to prevent and extinguish fires.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If helicopters are used to drop water on forest fires, then fire suppression capability is improved, but response time is excessively long (2-5 hours) and operational cost increases

Engineering Contradiction:

Improvefire suppression capabilityVSAvoidresponse time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary action by pre-positioning water tanks and fire detection devices within the forest area before fires occur. Detection devices continuously monitor for fire conditions, and water is already available at the site, eliminating the need for lengthy transport from distant water sources. This allows immediate response when fire is detected.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary automated system consisting of detection devices, control units, and spray mechanisms that mediate between fire occurrence and suppression action. This automated intermediary system eliminates the need for human pilots and firefighters to be directly involved in the response chain, enabling faster and more reliable fire suppression.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If helicopters and air tankers are deployed for forest fire control, then fire suppression capability is improved, but operational cost and jet fuel consumption increase significantly

Engineering Contradiction:

Improvefire suppression capabilityVSAvoidjet fuel consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system employs self-service principles by using automated detection devices that continuously monitor for fire conditions without human intervention. When fire is detected, the control unit automatically activates spray mechanisms, eliminating the need for pilots, firefighters, and support personnel. This automation significantly reduces operational costs and energy consumption associated with human-operated aircraft and ground crews.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical system of helicopter-based water dropping with an automated ground-based detection and spray system. This substitution eliminates the need for jet-powered aircraft entirely, replacing them with electrically-powered spray mechanisms that consume minimal energy, thereby dramatically reducing fuel consumption and operational costs.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If helicopters are used to extinguish forest fires, then fire suppression capability is improved, but safety risk to pilots and firefighters increases

Engineering Contradiction:

Improvefire suppression capabilityVSAvoidsafety risk to personnel

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system extracts human personnel from the fire suppression process entirely. Detection devices, control units, and spray mechanisms operate autonomously without requiring pilots or firefighters to be present in or near the fire zone. This extraction of human elements eliminates the safety risks associated with operating near active forest fires while maintaining effective fire suppression capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The automated system performs all fire suppression functions without human intervention, making the system self-sufficient and eliminating exposure to harmful factors. Detection devices autonomously identify fire conditions, control units process information and make decisions, and spray mechanisms execute suppression actions, thereby protecting personnel from smoke, heat, and physical danger.

Inventive Principle:

Principle #25Self-service

4Reliability

If traditional fire suppression methods are used, then fire control capability is improved, but environmental safety deteriorates due to harmful chemicals and long response time

Engineering Contradiction:

Improvefire control capabilityVSAvoidenvironmental harm

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The system changes the parameter of response time from hours to minutes or seconds by pre-positioning detection devices and water supplies within the forest area. This parameter change enables immediate suppression action that prevents fire spread and reduces the need for harmful chemical retardants, thereby protecting the environment while maintaining effective fire control.

Inventive Principle:

Principle #35Parameter changes
