Gas Regulator Multi-Angle Display and Segmented Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas regulators have a red display for indicating gas exhaustion that is obscured when something covers the regulator body, making it difficult for users to determine the gas usage status, and the connection between high-pressure and low-pressure portions lacks sufficient resistance to prevent deformation and loosening.
Innovation Solution
A gas regulator design featuring a low-pressure portion, high-pressure portion, and intake switchover valve with a diaphragm, pushing block, elastic element, support base, display diaphragm, and cover, where the pushing block is outside the diaphragm, and the connection is enhanced with stepped teeth and locking slots for improved resistance, and transparent display windows allow clear observation of gas status from multiple angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the red display is set above the regulator body, then the gas exhaustion status can be shown, but the display may be obscured when something covers the regulator body, making it difficult for users to observe
Solution Approach 1:
The patent moves the display window from a single top position to multiple positions including the side surface and outer end of the regulator body. This spatial dimensionality change allows users to observe the gas exhaustion status from multiple angles (top, side, and front), eliminating the problem of the display being obscured when objects cover the top of the regulator.
2Ease of manufacture
If the connection between high-pressure portion and low-pressure portion is simple, then the structure is easy to manufacture, but the connection lacks sufficient stretching resistance and torsional resistance, causing deformation and loosening
Solution Approach 1:
The connection structure is segmented into multiple functional components: stepped teeth formed on the outer periphery of the high-pressure portion's air outlet, corresponding stepped locking slots on the inner periphery of the low-pressure portion's air inlet, and a sealed pad. This segmentation allows each component to perform its specific function while working together to provide both manufacturing simplicity and connection reliability.
Solution Approach 2:
The connection structure applies local quality by concentrating the locking and sealing functions at specific locations: the stepped teeth and locking slots are positioned at the interface between high-pressure and low-pressure portions to provide mechanical interlocking, while the sealed pad is placed at the front end of the air outlet to provide sealing. This localized functional distribution ensures connection stability without complicating the overall structure.
Applied Scientific Principles
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 ensures that the gas regulator's status is clearly visible from multiple sides, preventing the display from being hidden and providing better resistance to deformation and loosening, thus enhancing its operational effectiveness.
Implementation Method 1
an elastic element (33)... The elastic element is sleeved the pushing block (32) and between the pushing block (32) and the flange (321)... When the gas is not introduced into the high-pressure portion (1), the elastic element (33) pushes the pushing block (32) and the support base (34) apart

AI summary
A structure of gas regulator comprises a space for setting an intake switchover valve formed at an outer end of a high-pressure portion and interconnected with the inside of the high-pressure portion. A pushing block is outside a diaphragm, and an elastic element is set between the pushing block and a flange at the periphery of an inner end of the pushing block. A support base outside the pushing block is abutted the elastic element and comprises an extending section extended from an inner end thereof and corresponding to the outer periphery of the elastic element and a through-hole corresponding to the pushing block. A display diaphragm with a center slot is outside the support base. A cover covered the space has a transparent side display window at the periphery thereof and a transparent outer display window at an outer end thereof.
