Liquid Gas Bottle Fitting With Rotary Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The technical effort required for refilling liquid gas bottles is high due to the need for manual alignment and separate components for lateral and centric filling, which increases the complexity and space requirements of the filling process.
Innovation Solution
A fitting with a rotary handle and a closable opening on the upper side that allows for automated refilling, reducing the number of components and installation space, and enabling refilling from above with minimal centering effort, using a single-piece construction for the rotary handle and housing to simplify manufacturing and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lateral connection piece is used for filling, then the fitting structure is simple, but manual alignment and centering effort are required increasing the technical effort for refilling
Solution Approach 1:
The patent introduces a centric filling point on the upper side of the fitting, allowing refilling from above instead of requiring lateral alignment. This dimensional change in the filling approach eliminates the need for manual alignment of lateral connection pieces, directly reducing the technical effort for refilling operations.
Solution Approach 2:
The fitting integrates both a lateral gas tap for withdrawal and an upper centric opening for refilling into a single device. This multi-functionality allows the same fitting to handle both gas consumption and refilling operations, reducing the overall complexity of the filling process by eliminating separate components.
2Adaptability or versatility
If separate components are used for lateral and centric filling, then functional versatility is achieved, but the number of components increases reducing ease of manufacture
Solution Approach 1:
The patent combines the lateral gas tap and upper centric opening into a single integrated fitting structure. By merging these functions into one component rather than using separate parts, the manufacturing effort is reduced while maintaining the versatility to perform both gas withdrawal and refilling operations.
Solution Approach 2:
The fitting is designed as a multi-functional component that handles both gas consumption through the lateral tap and refilling through the upper opening. This universality eliminates the need for multiple separate components, directly improving ease of manufacture while preserving functional versatility.
3Device complexity
If a lateral gas tap is used, then the fitting structure is simple, but installation space requirements increase due to protruding components
Solution Approach 1:
The patent positions the refilling opening on the upper side of the fitting rather than extending it laterally. This dimensional repositioning allows refilling access from above without requiring additional lateral protrusion, thereby reducing the installation space requirements while maintaining structural simplicity.
