Innovation Solution
An integral volume and pressure regulating device is designed with a combined body incorporating a pressure regulating member and a volume regulating member, featuring a path assembly, pressure valve assembly, and volume valve assembly, which includes a sealing mechanism and adjustable components to stabilize gas flow and control both pressure and volume within a compact structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pressure regulating device and volume regulating device are connected by plastic hose or metal hose, then the devices can be separately positioned, but the hose is easily loosened by vibration and might be disconnected
Solution Approach 1:
The patent combines the pressure regulating device and volume regulating device into a single integrated unit with a unified housing structure. The pressure regulating member and volume regulating member are housed within the same body, eliminating the need for external hose connections between separate devices. This merging resolves the contradiction by maintaining separate functional positioning while ensuring reliable connection through structural integration.
2Adaptability or versatility
If pressure regulating device and volume regulating device are connected by plastic hose or metal hose, then the devices can function independently, but the combination occupies too much space
Solution Approach 1:
The patent implements a nested structure where the volume regulating member is positioned within the housing of the pressure regulating device. The second housing contains the volume regulating member while being integrated with the first housing that contains the pressure regulating member. This nesting arrangement allows both devices to function independently while occupying minimal space, resolving the contradiction between functional independence and compact size.
3Ease of manufacture
If conventional pressure regulating device and volume regulating device are used separately, then each device can be optimized independently, but the loose connection leads to safety hazards
Solution Approach 1:
The patent merges the pressure regulating device and volume regulating device into a single integrated assembly with a unified housing. The pressure regulating member and volume regulating member are positioned within the same housing structure with sealed communication paths, eliminating external hose connections that could loosen. This merging maintains independent optimization of each regulating function while eliminating safety hazards from loose connections through structural integration.
