Solution Overview

Problem

Existing valve arrangements requiring multiple valves for fluid control necessitate complex and costly setups with separate actuation signals, demanding manual configuration and high external control device complexity.

Innovation Solution

A valve arrangement combining a 2/2-way proportional valve and a switching valve, actuated by a control device generating individual signals for each valve based on a single setpoint signal, simplifying control and reducing manual configuration needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple valves are used for fluid control, then fluid flow control capability is improved, but device complexity and control signal requirements increase

Engineering Contradiction:
Improvefluid flow control capabilityVSAvoidcontrol device complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple valve functions (proportional valve for flow control and switching valve for direction control) into a single integrated valve arrangement that responds to one actuation signal. The control device integrates the functionality of multiple separate valves, reducing the number of independent control signals needed while maintaining comprehensive fluid control capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The valve arrangement is designed to perform multiple functions (proportional flow control, switching, and direction control) through a single actuation signal. The control device acts as a universal controller that manages both proportional and switching valve operations, eliminating the need for separate control circuits for each valve type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If multiple separate actuation signals are provided for each valve, then individual valve control precision is improved, but external control device complexity increases

Engineering Contradiction:
Improvevalve control precisionVSAvoidexternal control device complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The control device merges the generation of multiple actuation signals into a single integrated unit. Instead of requiring external controllers to generate separate signals for proportional and switching valves, the control device internally generates both actuation signals based on one actuation signal, simplifying the external control architecture while maintaining precise individual valve control.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If manual configuration is required for valve arrangements, then adaptability to different applications is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveapplication adaptabilityVSAvoidease of actuation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The valve arrangement is designed to automatically adapt to different applications through self-configuration capabilities. The control device can automatically determine the appropriate actuation signals and valve settings based on the application requirements, eliminating the need for manual configuration while maintaining high adaptability to different fluid control scenarios.

Inventive Principle:
Principle #25Self-service
