Liquid Filling Component with Intermediate Widening Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filling components for liquid containers, such as those used in vehicles for washing water or cooling liquids, experience turbulence and foam formation due to their small circular cross-section and narrow bending radii, leading to slow and interrupted filling processes.
Innovation Solution
A component with an intermediate section that widens between the filler neck and outlet section, calming the liquid and reducing dynamic pressure, thereby preventing foam formation and allowing for uninterrupted, quicker filling by deflecting the liquid flow against a chamber wall and guiding it laterally out of the chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional filling component with small circular cross-section and narrow bending radii is used, then the component structure is simple, but the liquid flow becomes turbulent causing foam formation and slow filling
Solution Approach 1:
The patent introduces an intermediate section with a widening chamber that adds a volumetric dimension to the filling path. This chamber allows the liquid to expand and calm down, transitioning from a narrow turbulent flow to a broader laminar flow, thereby increasing filling speed without excessive complexity
Solution Approach 2:
The filling component is divided into distinct sections: a filler neck, an intermediate section with widening chamber, and an outlet section. This segmentation allows each part to perform its specific function - the intermediate section specifically addresses turbulence by providing a calming chamber, improving overall filling efficiency
2Productivity
If the liquid is filled quickly into the component, then productivity increases, but turbulence and foam formation increase causing filling interruptions
Solution Approach 1:
The intermediate section with its widened chamber acts as a cushioning zone before the liquid enters the outlet section. This chamber absorbs the kinetic energy and turbulence of the incoming liquid, preventing foam formation and ensuring continuous reliable filling without interruptions
3Productivity
If the component has a consistent small circular cross-section, then manufacturing is simple, but liquid turbulence causes foam and slow filling
Solution Approach 1:
The component features a localized widening in the intermediate section while maintaining simple circular cross-sections in the filler neck and outlet sections. This local quality change - the widening chamber - is sufficient to calm the liquid without requiring complex geometry throughout the entire component, balancing manufacturability with improved filling performance
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 enables efficient and rapid filling of liquids into containers without interruptions, effectively reducing turbulence and foam formation, allowing for faster and more efficient liquid transfer.
Implementation Method 1
The contact of the liquid with the inner wall of such filling components causes turbulence in the liquid and a dynamic pressure in the liquid
Implementation Method 2
a liquid poured into the filler neck is guided against the lower wall 8 of the chamber 7 which is arranged opposite the filler neck
