Semi-Flexible Gas Manifold Valve Assembly for Precise Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rigid manifold constructions in gas ranges are expensive and difficult to position valves accurately, especially in creative locations, due to the need for precise manufacturing and alignment.
Innovation Solution
A manifold and valve assembly using a semi-flexible tube, such as aluminum or copper, captured between a valve body and a connection device, which allows for flexible positioning and eliminates the need for predrilled holes, with separate connections to the appliance for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid manifold constructions are used, then structural strength and positioning stability are improved, but manufacturing cost and positioning flexibility worsen
Solution Approach 1:
The patent replaces rigid manifold constructions with flexible tubing that can be bent and shaped to accommodate various valve positions. The flexible tube maintains sufficient structural strength while allowing easy positioning and creative location placement without expensive precision manufacturing
Solution Approach 2:
The invention separates the manifold into discrete segments (individual tubes connecting valves) rather than a single rigid structure. This allows each tube to be independently positioned and connected, improving flexibility while maintaining overall structural integrity through connection points
2Manufacturing precision
If rigid manifolds with precise hole locations are used, then valve alignment precision is improved, but manufacturing complexity and cost worsen
Solution Approach 1:
The patent transitions from fixed, pre-drilled hole locations in rigid manifolds to flexible tubing that can be dynamically positioned and routed to accommodate various valve locations. The flexible tube adapts to different configurations without requiring precision manufacturing of hole patterns
Solution Approach 2:
The invention changes the key parameter from fixed geometric positions to flexible routing capabilities. The tube's flexibility allows position parameters to be adjusted during installation rather than being fixed during manufacturing, simplifying the overall construction process
3Adaptability or versatility
If separate brackets and connection devices are used, then valve positioning flexibility is improved, but assembly complexity worsens
Solution Approach 1:
The patent combines the manifold tubing with the connection function by integrating connection points directly into the flexible tube assembly. This merging eliminates the need for separate brackets and connection devices, reducing component count while maintaining positioning flexibility

AI summary
A semi-flexible tube is captured between a valve body and a connection device wherein at least one of the valve body and the connection device is connected structurally to a range instead of relying on the manifold tube as the location mechanism for precisely locating the valve at a desired location on the range.
