Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas regulators require separate devices to control and measure pressure and flow rate, leading to inefficiency and safety concerns, especially in applications requiring multiple pressure settings and operations like brazing and pressure testing.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate pressure regulators and flowgauge regulators are used, then precise control of pressure and flow rate is achieved, but device complexity and operational inefficiency increase
Solution Approach 1:
The patent combines the functions of a pressure regulator and a flowgauge regulator into a single hybrid regulator device. The outlet assembly integrates both pressure regulation and flow rate measurement capabilities, allowing users to control and monitor both parameters simultaneously through one device rather than requiring separate regulators.
Solution Approach 2:
The hybrid regulator is designed to perform multiple functions: it regulates pressure, measures flow rate, and provides visual indication of both parameters through a single device. The outlet assembly serves as a multi-functional component that handles both pressure control and flow measurement tasks that traditionally required separate specialized devices.
2Reliability
If multiple regulators are used for different operations, then specific pressure and flow rate requirements are met, but ease of operation and safety decrease
Solution Approach 1:
By merging pressure regulation and flow measurement functions into one device, the patent eliminates the need for operators to switch between multiple regulators during different operations. The unified design allows continuous monitoring and control of both pressure and flow rate parameters through a single interface, reducing operational complexity and potential safety risks associated with device switching.
3Device complexity
If a single regulator handles both pressure and flow control, then device complexity is reduced, but measurement precision and control accuracy may worsen
Solution Approach 1:
The outlet assembly is segmented into distinct functional zones: a first zone for flow rate control with associated indicia, and a second zone for pressure control with associated indicia. This segmentation allows each function to be optimized independently within the unified device structure, maintaining measurement precision for both parameters while achieving device integration.
Solution Approach 2:
Different portions of the outlet assembly are designed with locally optimized characteristics: the first portion provides flow rate control and indication suitable for specific operations like brazing and purging, while the second portion provides pressure control and indication for operations requiring specific pressure levels. Each local region is tailored to its specific function while contributing to the overall integrated system.

AI summary
An outlet assembly (141) for a hybrid pressure and flowgauge regulator comprises a housing (140) defining an internal cavity (150). A first orifice (168) of a first size is disposed proximate both an upstream end of the internal cavity (150) and an upstream end of a main pathway (173) that extends longitudinally through the internal cavity (150). A second orifice (158) of a second size that is larger than the first size is disposed proximate a downstream end of the internal cavity (150). One or more auxiliary pathways (174) are disposed between the first orifice (168) and the second orifice (158) and extend perpendicularly to the main pathway (173). An internal mechanism (166) automatically moves the first orifice (168) between two distinct positions: (i) a first position, wherein a flow of gas through the outlet assembly (141) passes through both the first orifice (168) and the second orifice (158) when the first orifice is in the first position so that the flow of gas exits the outlet assembly with a first flow rate, the flow of gas flowing through the main pathway (173) between the first orifice and the second orifice; and (ii) a second position, wherein the flow of gas primarily bypasses the first orifice (168) and flows through the one or more auxiliary pathways (174) into the main pathway (173) before flowing through the second orifice (158) when the first orifice is in the second position so that the flow of gas exits the outlet assembly (141) with a second flow rate.
