Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure regulators for high-pressure gas storage units become bulky due to multiple regulating assemblies, making them inconvenient for mobile applications where space is limited.
Innovation Solution
A pressure regulator design with a valve tube assembly, gas-input assembly, first and second regulating assemblies, and a gas storage unit, where the high-pressure piston chamber communicates with the outside through a high-pressure gas channel to maintain operation while reducing overall volume by embedding the pressure regulator partially within the gas storage unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple regulating assemblies are used to reduce gas pressure from high pressure source to usable level, then the safety and precision of pressure adjustment is improved, but the overall volume of the pressure regulator is enlarged
Solution Approach 1:
The valve tube assembly is disposed inside the gas storage unit, with the high-pressure piston chamber positioned within the storage unit's interior space. This nesting arrangement allows the pressure regulator components to occupy the internal volume of the gas storage unit rather than adding external volume, thereby maintaining multi-level pressure regulation capability while reducing the overall device footprint.
Solution Approach 2:
The patent utilizes the internal three-dimensional space of the gas storage unit by positioning the high-pressure piston chamber inside the storage unit and extending the valve tube assembly through the side wall. This spatial reconfiguration transforms the arrangement from an external multi-component layout to an integrated internal structure, achieving compact volume while maintaining the multi-stage pressure reduction function.
2Volume of stationary object
If the pressure regulator is embedded in the gas storage unit to reduce overall volume, then the portability is improved, but the high-pressure piston chamber must communicate with outside through high-pressure gas channel to maintain normal operation
Solution Approach 1:
The side wall of the gas storage unit serves multiple functions: it acts as the container wall for the high-pressure gas storage unit, provides the opening for the valve tube assembly to extend through, and forms part of the high-pressure gas channel pathway. This multi-functional design reduces the need for separate dedicated components for high-pressure gas communication, thereby reducing overall device complexity despite the embedded configuration.
3Ease of operation
If conventional pressure regulators are used for mobile high pressure source, then the pressure regulation function is achieved, but the enlarged volume makes it inconvenient to carry
Solution Approach 1:
The pressure regulator components (valve tube assembly, high-pressure piston chamber, regulating assemblies) are merged with the gas storage unit by disposing the valve tube assembly inside the storage unit and integrating the high-pressure gas channel into the storage unit's wall structure. This merging eliminates the need for separate external pressure regulator housing, significantly reducing the overall volume of the mobile high-pressure source while maintaining full pressure regulation functionality.

AI summary
A pressure regulator has a valve tube assembly, a gas-input assembly, a first regulating assembly and a second regulating assembly. The gas storage device has a storage unit and the pressure regulator. By the first and the second regulating assemblies, the effect of adjusting down the gas pressure is achieved to maintain the safety of use. The pressure regulator is partially embedded in the gas storage unit to reduce the overall volume of the gas storage device. However, the high-pressure piston chamber of the valve tube assembly communicates with the outside of the gas storage unit through the high-pressure gas channel to maintain the normal operation of the elastic element in the high-pressure piston chamber.
