Remote Wildfire Sprayer Mixing for Property Barrier Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wildfires can spread rapidly and are difficult to control, with existing fire retardant systems often requiring manual operation, which puts personnel at risk and may not provide efficient or timely protection.
Innovation Solution
A wildfire defense apparatus with mobile and fixed configurations, featuring tanks for storing fluids, pumps, a mixing valve, and sprayers, controlled remotely to dispense a mixture of water and fire retardant gel or suppressant, allowing for automated and preconfigured spraying cycles to create a protective barrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation of fire retardant systems is used, then personnel can directly control the spraying process, but personnel are exposed to risk during wildfire events and response time is delayed
Solution Approach 1:
The patent introduces a remote control system as an intermediary between the operator and the fire retardant dispensing system. The controller receives signals from remote devices and automatically actuates pumps and valves, allowing operators to control the system from a safe distance without direct exposure to wildfire hazards.
Solution Approach 2:
The system incorporates automated control logic that enables the fire retardant dispensing apparatus to operate autonomously based on pre-programmed sequences or real-time sensor inputs. The pumps, valves, and spray mechanisms can function without continuous manual intervention, reducing the need for personnel to be physically present in dangerous zones.
2Productivity
If fire retardant is dispensed rapidly to create protective barriers, then fire containment effectiveness is improved, but the complexity of fluid mixing and dispensing control increases
Solution Approach 1:
The system divides the fluid dispensing function into separate independent pumps for water and fire retardant concentrate. Each pump can be controlled independently to achieve desired mixing ratios, and the segmented architecture simplifies the overall control logic while enabling high dispensing rates through parallel operation.
Solution Approach 2:
The patent employs dynamically adjustable flow control valves and variable speed pumps that can automatically modulate their operation based on real-time conditions. This dynamic control allows the system to maintain optimal mixing ratios and dispensing rates automatically, reducing the complexity of manual coordination while maximizing productivity.

AI summary
A wildfire defense system includes a first tank for storing a first fluid, a second tank for storing a second fluid, a mixing valve, two pumps, a controller, and one or more sprayers. The wildfire defense system is controllable remotely allowing property owners to protect structures prior to wildfires without having to be on their property. The first pump pumps the first fluid from the first tank to the mixing valve, and the second pump pumps the second fluid from the second tank to the mixing valve. The controller controls the operations of the pumps and the mixing valve. The mixed fluid is sprayed over a selected geographic region through the sprayers. The apparatus can be remotely activated and the ratio of the first fluid to the second fluid in the mixed fluid is configurable. The system is transportable, allowing for easy relocation or fixed in a dedicated location.
