Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual adjustment and pairing operations are performed for each valve type, then the valve controller can be adapted to specific valve variants, but the installation becomes complex and time-consuming

Engineering Contradiction:

Solution Approach 1:

The valve controller automatically detects valve parameters and performs self-configuration by reading signals from the valve position sensor during installation, eliminating the need for manual adjustment and pairing operations. The controller autonomously determines valve type, stroke length, and other parameters through the sensor feedback mechanism.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The valve position sensor is pre-configured to provide signals that contain valve identification information. During installation, the controller automatically reads these pre-encoded signals to determine valve parameters before operation begins, avoiding post-installation configuration steps.

AI summary

A valve controller (10) for controlling a valve (12) is disclosed. The valve controller has an actuator (14) and a flow controlling unit (16). The valve controller (10) is configured to execute a setup process and comprises a first pilot valve (24) that can energize the actuator by allowing a first pressurized fluid to enter the actuator and deenergizing the actuator by allowing the fluid to leave the actuator. The valve controller (10) further has an input device (66) by which the setup process can be initiated, and a memory unit (64) for storing setup parameter values. The setup process comprises: determining (102) one or more parameter values indicative of the functionality of at least one of the valve controller (10), the actuator and the flow controlling unit (16), and storing (104) the one or more parameter values as one or more setup parameter values in the memory unit (64).
