Solution Overview
Problem
Existing valve devices are large and expensive to manufacture due to their complex configurations, which hinder compactness and simplified production.
Innovation Solution
A compact valve device design incorporating a pressure regulator with a diaphragm, spring, and control actuator, where the control actuator includes a plate-like and rod-like portion, mechanically coupled with a ring-shaped control seat, allowing for axial movement and gas flow regulation, and utilizing a housing with a recess for the control seat to reduce size and manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pressure regulator is combined with valves in a shared housing, then the device can perform multiple functions, but the device becomes large and expensive to manufacture
Solution Approach 1:
The patent combines the pressure regulator and valve functions into a single integrated device with a common housing and shared components. The control actuator serves both the pressure regulation diaphragm and the valve sealing function, merging two previously separate functions into one unified structure that reduces overall device size and manufacturing complexity
Solution Approach 2:
The control actuator is designed as a multi-functional component that simultaneously performs pressure regulation control and valve operation. By making this single component responsible for both functions, the patent eliminates the need for separate actuators, thereby reducing device volume while maintaining full functionality
2Adaptability or versatility
If a pressure regulator is combined with valves in a shared housing, then the device can perform multiple functions, but the manufacturing cost increases
Solution Approach 1:
The patent merges the pressure regulator and valve into a single manufacturing unit with a common housing and shared components. This integration allows for simplified assembly processes and reduced part counts, which directly lowers manufacturing costs despite the increased functional complexity
3Reliability
If the control actuator is moved against the spring force, then the gas pressure can be regulated, but a greater force must be applied
Solution Approach 1:
The control actuator is designed to move dynamically between two positions: a first position where it contacts the diaphragm for pressure regulation, and a second position where it contacts the control seat for flow interruption. This dynamic positioning allows the system to achieve reliable pressure regulation while managing the force requirements through controlled movement rather than continuous high force application

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves a compact structure and simplified manufacturing, enabling efficient gas pressure regulation while preventing excessive gas flow, thus reducing production costs and size.
Implementation Method 1
the spring and the control actuator being mechanically coupled to each other in such a way that the spring urges the control actuator toward a face side of the control seat
Implementation Method 2
the diaphragm and the control actuator being mechanically coupled to each other such that an axial movement of the control actuator moves the diaphragm

AI summary
The invention relates to a valve device (1) having a pressure regulator (3) for a flowing gas and a housing (4). The pressure regulator (3) includes a diaphragm (31), a spring (34), a control actuator (32), and a control seat (33). The control actuator (32) includes a plate-like portion (32′) and a rod-like portion (32″) adjacent to one side of the plate-like portion (32′), the control seat (31) encompassing the rod-like portion (32″) of the control actuator (32). The diaphragm (31) and the control actuator (32) are mechanically coupled to each other such that an axial movement of the control actuator (32) moves the diaphragm (31). In addition, the spring (34) and the control actuator (32) are mechanically coupled to each other. The control seat (33) limits a movement of the control actuator (32). In one state, the control seat (33) and the control actuator (32) prevent the gas from flowing. The control seat (33) is configured as a ring arranged in a recess (40) of the housing (4).
