Removable Valve Control with Auto Reset After Actuator Reassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve control devices require manual user input for reset and recalibration during changes or maintenance, which complicates handling and increases costs due to the need for user interfaces and complex design.
Innovation Solution
A valve control device equipped with a position sensor, memory device, and electronic control unit that automatically detects separation and assembly from the valve actuator, allowing for automatic reset of position data without user intervention, eliminating the need for a user interface and simplifying the design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual user input is used for reset and recalibration, then the valve control device can be operated, but handling is complicated and costs increase due to user interface requirements
Solution Approach 1:
The valve control device automatically detects separation and assembly events through sensor signals and autonomously performs reset operations without requiring user interaction. The system serves itself by monitoring its own state changes and executing appropriate control actions, eliminating the need for manual user input and complex user interfaces.
Solution Approach 2:
The system uses feedback from position sensors and separation detection mechanisms to automatically determine when reset operations are needed. The control unit continuously monitors sensor signals and automatically triggers recalibration based on detected state changes, creating a closed-loop system that eliminates manual intervention.
2Reliability
If manual reset process is implemented, then the valve control device can be recalibrated, but time is lost due to user intervention requirements
Solution Approach 1:
The system automatically performs reset and recalibration actions immediately upon detecting separation or assembly events, without waiting for user intervention. By initiating the recalibration process automatically at the moment it is needed, the system eliminates delays associated with manual user response time while ensuring proper calibration is performed.

AI summary
A valve control device for controlling operation of a valve actuator configured to be connected to a valve member. The valve control device being configured to be removably mounted on the valve actuator and comprises: a position sensor for detecting actuating position of the valve actuator and outputting the detected position as a feedback signal; a memory device for storing position data reflecting the feedback signal from the position sensor at at least one actuating position of the valve actuator; and an electronic control unit for controlling operation of the valve actuator using the feedback signal from the position sensor and the position data from the memory device; wherein the electronic control unit is configured for automatically performing a reset of the position data of the memory device as a result of the valve control device becoming separated from, and/or assembled on, the valve actuator.
