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

VSEngineering 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If gas is released laterally from the valve, then gas can be withdrawn from the gas cartridge, but lateral recoil forces cause the gas cartridge to tilt and leaks occur

Engineering Contradiction:
Improvegas withdrawal capabilityVSAvoidsealing reliability
Core Design Contradiction:
ProductivityVSReliability

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

Inventive Principle:
Principle #13The other way round (Inversion)

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

Engineering Contradiction:
Improvegas flow direction controlVSAvoidvalve structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

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

Inventive Principle:
Principle #15Dynamics

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

Inventive Principle:
Principle #1Segmentation
