Battery-Powered Control Valve for Reliable Remote Operation
Here’s PatSnap Eureka !
Summary
Problems
Valves used to control fluid and gas flows in remote or dangerous areas often require high energy levels for consistent operation, leading to inefficiency and reliability issues due to environmental conditions, and existing solutions require wired connections to large power supplies, which are susceptible to environmental factors.
Innovation solutions
A battery-powered control valve system that uses a capacitor charged by a battery and a DC/DC converter to apply energy to a solenoid latching valve for controlled periods, adjusting energy application based on pressure sensor feedback to match desired states and optimizing energy use by adjusting actuation times based on successful and unsuccessful attempts.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If high energy levels are applied to operate valves in remote and hazardous locations, then valve operation reliability is improved, but energy consumption increases
Why choose this principle:
The system dynamically adjusts the actuation period based on environmental conditions and valve state. The controller modifies the duration of energy application to the solenoid coil, applying energy for longer periods when conditions require it and shorter periods when conditions are favorable, thereby maintaining reliability while optimizing energy consumption.
Principle concept:
If high energy levels are applied to operate valves in remote and hazardous locations, then valve operation reliability is improved, but energy consumption increases
Why choose this principle:
The pressure sensor provides feedback about the valve state and environmental conditions to the controller. This feedback loop enables the system to determine when the valve has reached its target state and adjust subsequent energy application accordingly, preventing unnecessary energy consumption while ensuring reliable operation.

Abstract
The present disclosure describes, among other things, a method. The method may include receiving an instruction to actuate a valve. The method may also include receiving a first period of time. The method may also include applying energy to the valve for the first period of time. The method may also include comparing a first state of the valve with a state in the instruction. The method may also include determining a second period of time by increasing the first period of time. The method may also include applying energy to the valve for the second period of time. The method may also include determining that a second state of the valve matches the state in the instruction.
