Solution Overview
Problem
Existing fire-fighting control systems rely on manual operation by an engineer, leading to increased costs and potential human errors 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 and easy to manufacture, but human error increases and operational efficiency decreases
Solution Approach 1:
The control system automatically monitors parameters and adjusts valve positions without requiring continuous manual intervention. The system serves itself by using sensors to detect conditions and the controller to automatically actuate valves, reducing reliance on human operators and minimizing human error while maintaining operational reliability.
Solution Approach 2:
The patent replaces manual mechanical control operations with an automated electronic control system. The controller uses electronic signals to actuate valves based on sensor input, substituting the mechanical manual operation with an automated electromechanical system that reduces human error and improves reliability.
2Productivity
If remote control capability is added, then operational efficiency improves and safety increases, but device complexity and cost increase
Solution Approach 1:
The control system is divided into separate functional modules: sensors for parameter detection, a controller for decision-making, and actuators for valve control. This segmentation allows the system to achieve remote control capability and improved operational efficiency while managing complexity through modular design, where each component has a specific function.
Solution Approach 2:
The controller acts as an intermediary between the sensors and the valve actuators. It receives signals from sensors, processes the information, and sends control signals to the actuators, enabling remote control operation. This intermediary function allows operational efficiency to improve through automation while keeping the system architecture manageable through clear separation of concerns.
3Measurement precision
If automatic control based on multiple parameters is implemented, then measurement precision and control accuracy improve, but the number of required sensors and system complexity increase
Solution Approach 1:
The controller is designed to handle multiple sensor inputs and control multiple valves using a single multi-functional device. Rather than requiring separate control circuits for each parameter, the universal controller can process pressure, flow rate, and temperature signals from multiple sensors and coordinate valve actuation accordingly, improving measurement precision without proportionally increasing the quantity of components.

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.
