Solution Overview
Problem
Existing fire-fighting control systems rely on manual operation by an engineer, leading to increased costs and human error due to the need for verbal communication and lack of remote control capabilities, which also limits training simulations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual control operation is used, then the system is simple to operate, but human error increases and remote control capability is lost
Solution Approach 1:
The control system automatically monitors fluid parameters (pressure, flow rate, temperature) and adjusts pump and valve operations without requiring continuous manual intervention. The system serves itself by using sensors to detect parameter deviations and the controller to automatically issue adjustment commands, thereby reducing human error while maintaining operational simplicity.
Solution Approach 2:
The patent replaces manual mechanical control operations with an automated electronic control system. The controller receives sensor data and automatically generates control signals for pumps and valves, substituting the engineer's manual manipulation of mechanical controls with an electronic feedback control loop that eliminates human error in parameter adjustment.
2Adaptability or versatility
If remote control capability is added, then operational flexibility improves, but system complexity increases
Solution Approach 1:
The control system is designed to perform multiple functions: it monitors fluid parameters, controls pump operations, adjusts valve positions, and enables both local and remote operation modes. This multi-functionality allows the same system to provide operational flexibility and remote capability without requiring separate dedicated systems for each function, thereby limiting the increase in overall complexity.
Solution Approach 2:
The controller acts as an intermediary between the sensors, actuators (pumps and valves), and the operator (whether local or remote). It processes sensor data, makes control decisions based on predefined logic, and sends commands to actuators, thereby simplifying the interface between the complex physical system and the operator while enabling remote control capability.
3Productivity
If automated control is implemented, then productivity increases, but initial system cost increases
Solution Approach 1:
The automated control system continuously monitors fluid parameters and self-adjusts pump and valve operations without requiring constant human intervention. This self-service capability increases productivity by enabling uninterrupted operation and faster response to parameter changes, while the use of standard off-the-shelf sensors and controllers helps limit the increase in initial system cost.
Solution Approach 2:
The system uses sensors to continuously monitor fluid parameters (pressure, flow rate, temperature) and feeds this information back to the controller, which automatically adjusts pump and valve operations to maintain desired parameters. This feedback loop improves productivity by eliminating manual monitoring and adjustment cycles, while the simplicity of the feedback architecture helps control system cost.
Data Source
AI summary
A control system for use with a fire-fighting device includes a remote component having a touch sensitive screen configured to receive a user-requested parameter of fluid and to display a plurality of indicators associated with the fire-fighting device. The control system also includes a base component including a programmable logic controller having predefined logic stored thereon. The base component automatically controls operation of the pump based on the predefined logic and the user-requested parameter of fluid. The remote component receives signals from the base component and presents, via the touch sensitive screen, at least one of a first of the plurality of indicators indicative of a water volume associated with a first water source stored at a fire fighting device, and a second of the plurality of indicators indicative of a water pressure associated with a second water source remote from the fire-fighting device.
