Remote Vehicle Liquid Discharge Valve With Servo Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for applying liquids using remote operated vehicles require multiple users to operate the pressure source at ground level, interfering with the operation of the vehicle and necessitating a separate individual to control the liquid discharge.
Innovation Solution
A system integrated with a remote operated vehicle that includes a valve system, a servo actuator, and a pressure device, allowing a single user to control the discharge of liquids via wireless signals, utilizing a servo actuator to move the valve between fully open and closed positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pressure source is located at ground level and controlled by a user, then liquid discharge from the remote operated vehicle is enabled, but the user cannot simultaneously operate the remote operated vehicle controls
Solution Approach 1:
The patent combines the pressure source (pump) and valve control system into the remote operated vehicle itself, eliminating the need for a separate ground-level control system. The integrated system allows the vehicle to autonomously control its own liquid discharge without requiring a second user to operate separate controls.
Solution Approach 2:
The remote operated vehicle is equipped with its own integrated pump and valve system that can autonomously control liquid discharge. The vehicle serves itself by incorporating the pressure source and control mechanisms within its own structure, eliminating dependency on external ground-level operation.
2Ease of operation
If a separate user operates the pump at ground level, then liquid discharge is controlled, but an additional operator is required
Solution Approach 1:
The patent merges the pump, valve, and control systems into a single integrated unit mounted on the remote operated vehicle. This consolidation eliminates the need for separate ground-level operation and reduces the system to requiring only one operator who controls the vehicle's integrated system.
Solution Approach 2:
The vehicle incorporates its own pump and valve system that can be controlled from the vehicle itself or remotely, making the system self-sufficient. The integrated design allows the vehicle to manage its own liquid discharge without requiring additional personnel.
3Ease of operation
If the pump is controlled from ground level, then liquid discharge is manageable, but interference with remote operated vehicle operation occurs
Solution Approach 1:
The patent integrates the pump and control systems into the remote operated vehicle, eliminating the separation between vehicle control and liquid discharge control. This integration removes the source of interference by ensuring both functions are managed through the same control interface mounted on or within the vehicle.
Solution Approach 2:
The vehicle's integrated system allows it to control its own liquid discharge independently of ground-level operations. The pump and valve system are designed to be actuated by commands from the vehicle's own control system, preventing interference between vehicle navigation and liquid discharge functions.

AI summary
A system for discharging a liquid component from a remote operated vehicle includes the remote operated vehicle, a valve system, a pressure device, a liquid source, and a discharge nozzle. The valve system is attached to the top surface and/or the bottom surface of the platform, and includes a valve and a servo actuator. The valve includes a valve body, a valve disc within an interior of the valve body, and a stem attached to the valve disc and extending outside of the valve body. The servo actuator operatively connects to the stem. The pressure device includes a device inlet fluidly connected to the liquid source and a device outlet fluidly connected to a valve body inlet. The discharge nozzle is fluidly connected to a valve body outlet. The servo actuator is configured to operate on the valve stem to move the valve disc in a range of a fully open position and a fully closed position.
