Measuring Container Conduit Wall Flow for Foaming Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Measuring and dispensing containers with deformable reservoirs face issues of liquid velocity causing foaming and inaccurate measurements due to liquid spraying against measurement markings, and the risk of hazardous liquid splashing when transferring from a squeeze-bottle style reservoir to a measuring and dispensing chamber.
Innovation Solution
A measuring and dispensing container with a flexible walled reservoir and a conduit directing liquid to flow down a wall of the measuring and dispensing chamber, minimizing foaming and splashing by orienting the conduit to avoid turbulence and using a baffle or inclined walls to direct liquid entry, and incorporating features like angled dispensing outlets to prevent liquid retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid is transferred from a squeezable reservoir to the measuring and dispensing chamber, then liquid transfer is achieved, but liquid velocity causes foaming and inaccurate measurements
Solution Approach 1:
A baffle is introduced as an intermediary element between the liquid flow path and the measurement markings. The baffle intercepts the high-velocity liquid stream, causing it to flow down the chamber wall instead of directly impacting the measurement area, thus protecting measurement accuracy while maintaining transfer efficiency
Solution Approach 2:
The liquid transfer process is segmented into two distinct phases: a rapid filling phase where liquid flows down the wall, and a slower settling phase where foam subsides and accurate measurement can be taken. This temporal segmentation allows both high productivity and measurement precision
2Speed
If liquid enters the measuring and dispensing chamber at high velocity, then transfer speed is improved, but liquid sprays against measurement markings causing foaming
Solution Approach 1:
The high-velocity liquid stream, which would normally cause harmful spraying and foaming, is redirected to flow down the chamber wall where it can be observed as a clear stream. The kinetic energy that would create foam is instead used to create a visible flow pattern that aids in determining when the chamber is full
Solution Approach 2:
The baffle serves as a mediator that captures the harmful spray and redirects it along the chamber wall, converting the harmful spraying action into a useful visual indicator of liquid level
3Ease of operation
If the conduit is positioned to allow liquid entry, then liquid transfer is enabled, but hazardous liquid may splash out causing safety problems
Solution Approach 1:
The baffle acts as a protective intermediary barrier between the liquid transfer process and the surrounding environment. It contains the liquid flow within the chamber, preventing hazardous liquid from splashing out and exposing users to harm
Solution Approach 2:
The baffle is positioned in advance to intercept liquid flow before it can escape the chamber. This preliminary protective action prevents hazardous liquid exposure before it can occur

Function Achieved in This Case
The solution ensures accurate measurement and safe dispensing by minimizing foaming and splashing, allowing for precise liquid transfer and easy emptying without complete container rotation, reducing the risk of hazardous liquid exposure.
Implementation Method 1
liquid entering the measuring and dispensing chamber is directed to cause it to run down a wall of the measuring and dispensing chamber

AI summary
A container for measuring a predetermined amount of liquid and dispensing that measured amount. The container includes a reservoir chamber, a measuring and dispensing chamber, and a conduit or tube for transferring liquid from the reservoir chamber to the measuring and dispensing chamber. The reservoir chamber has flexible walls which can be squeezed to drive liquid from the reservoir chamber into the measuring chamber. The passage from the reservoir to the measuring and dispensing chamber is configured and its outlet arranged so that liquid entering the chamber flows down a wall thereof.
