Solution Overview

Problem

Existing solenoid valve control systems are complex and costly, requiring constant monitoring to adjust power consumption based on environmental conditions and valve life, which is not practical for widespread industrial use, especially for directional control valves operating in on/off positions.

Innovation Solution

A solenoid valve control system that uses an environmental sensor and a database to proactively optimize solenoid coil power consumption by cross-referencing operating temperature and valve cycles, reducing power consumption under normal conditions and increasing it as needed, without requiring continuous monitoring of coil resistance or performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the coil is designed to accommodate worst-case conditions (low temperature, aged components), then the valve can operate reliably under extreme conditions, but power consumption becomes excessive under normal conditions

Engineering Contradiction:
Improvevalve operation reliabilityVSAvoidcoil power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the coil power level adaptive rather than static. The controller dynamically adjusts the power supplied to the coil based on real-time monitoring of valve performance parameters (such as coil resistance, current draw, or actuation time). This allows the system to automatically increase power when the valve encounters difficult operating conditions (low temperature, aged components) and reduce power during normal operation, thereby resolving the contradiction between maintaining reliability and reducing energy consumption.

Inventive Principle:
Principle #15Dynamics

2Use of energy by moving object

If constant monitoring and adjustment of coil power is implemented, then power consumption can be optimized, but system complexity and cost increase

Engineering Contradiction:
Improvecoil power consumptionVSAvoidcontrol system complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent implements feedback control by continuously monitoring valve performance parameters (such as coil resistance, current, or actuation timing) and using this information to automatically adjust the power supplied to the coil. The controller receives feedback signals from sensors monitoring the valve's operational state and modifies the power output accordingly. This feedback mechanism enables automatic optimization of power consumption without requiring complex manual intervention or overly sophisticated control algorithms, thus balancing energy efficiency with system complexity.

Inventive Principle:
Principle #23Feedback

3Reliability

If the valve is designed for high power output to ensure adequate performance under all conditions, then reliability is improved, but energy efficiency deteriorates

Engineering Contradiction:
Improvevalve actuation performanceVSAvoidexcessive power consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies parameter changes by dynamically modifying the electrical parameters (voltage, current, or power level) supplied to the coil based on actual valve performance requirements. Rather than maintaining a fixed high power level, the controller adjusts these parameters in real-time according to monitored conditions such as coil resistance changes, current draw variations, or actuation timing deviations. This allows the system to maintain adequate actuation performance when needed while minimizing energy consumption during normal operation, effectively resolving the contradiction between reliability and energy efficiency.

Inventive Principle:
Principle #35Parameter changes

AI summary

The present disclosure provides a solenoid valve and associated method of control for compensated performance based on environmental conditions and optionally product life.
