Valve Gas Outlet Element Longitudinal Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas valves for soda makers experience lateral recoil forces when gas is removed, leading to potential tilting of the gas cartridge and leaks due to perpendicular force direction, which is not effectively managed by current designs.
Innovation Solution
A valve with a movably arranged gas outlet element that protrudes externally in a removal position, allowing gas to flow parallel to the longitudinal axis, reducing recoil forces by directing gas flow parallel to the axis, and featuring multiple outlet elements for increased flow section and optional internal actuation surfaces for movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gas is released laterally from the valve, then gas can be withdrawn from the gas cartridge, but lateral recoil forces cause the gas cartridge to tilt and leaks occur
Solution Approach 1:
The patent inverts the traditional lateral gas release direction by orienting the gas outlet opening to release gas in the longitudinal direction (parallel to the valve axis). This inversion eliminates lateral recoil forces that caused the gas cartridge to tilt and sealing failures, while maintaining effective gas withdrawal capability through the longitudinally oriented outlet
2Ease of operation
If the gas outlet element is moved to protrude externally, then gas flow direction is improved, but the valve structure becomes more complex
Solution Approach 1:
The patent employs a movable gas outlet element that can transition between retracted and protruding positions. This dynamic structure allows the outlet to protrude externally when needed for optimal gas flow direction and longitudinal release, while retracting when not in use to maintain a simpler overall valve structure and reduce complexity
Solution Approach 2:
The gas outlet element is designed as a separate, movable component distinct from the main valve body. This segmentation allows independent control of the outlet position, enabling it to protrude for improved gas flow direction while keeping the rest of the valve structure relatively simple and manageable
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 solution effectively reduces or eliminates perpendicular recoil forces, preventing cartridge tilting and leaks, while maintaining ease of insertion and operation by controlling gas flow direction and using excess pressure for actuation.
Implementation Method 1
with the at least one gas outlet element being movable in excess pressure into the withdrawal position
Implementation Method 2
gas can flow out of the valve in the direction parallel to the longitudinal axis
