Solution Overview

Problem

Pressurized gas storage containers, particularly those holding gaseous hydrogen at high pressures, require valves that can reliably control gas withdrawal operations while ensuring safety and adaptability to different uses, as existing solutions lack comprehensive control mechanisms for manual and automatic operation.

Innovation Solution

A valve with a displacement control circuit that allows for manual and electrical control of the isolation valve, enabling three secure operating modes, and includes a pressure relief mechanism and a proportional actuator to regulate outlet pressure, ensuring safe and precise gas withdrawal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a valve with only manual control is used, then the structure is simple, but the adaptability to different uses is limited

Engineering Contradiction:
Improveadaptability to different usesVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The valve integrates multiple control modes (manual and electrical) into a single device, allowing it to perform both manual operation and automated electrically-controlled operation. The body (3) contains both a manual control member (18) and an electric actuator (11) with a control circuit (10), enabling the valve to adapt to different usage scenarios without requiring separate valve systems.

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

2Ease of operation

If a valve with separate manual and remote control systems is used, then the control flexibility is improved, but the device complexity increases

Engineering Contradiction:
Improvecontrol flexibilityVSAvoidnumber of valves and controls
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines manual control and electrical control into a single integrated valve system. The control circuit (10) is integrated into the valve body (3), and the electric actuator (11) shares the same valve mechanism as the manual control member (18). This merging approach provides control flexibility while avoiding the complexity of having completely separate valve systems.

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If proportional control of the isolation valve is implemented, then the pressure regulation precision is improved, but the device complexity increases

Engineering Contradiction:
Improveoutlet pressure regulation precisionVSAvoidactuator control complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical pressure regulation mechanisms with an electrically-controlled proportional actuator (11). The actuator receives electrical control signals and proportionally adjusts the isolation valve (8) position, enabling precise outlet pressure regulation through electrical control rather than complex mechanical linkages.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
