Liquid Container with Bottom Air Inlet to Control Discharge Rate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart cleaning devices with liquid containers experience excessive liquid discharge due to equal air pressure inside and outside the container, leading to poor cleaning effects and potential damage.
Innovation Solution
The liquid container is designed with a bottom-mounted air inlet and liquid outlet, featuring a frustoconical air inlet with a large space above it and a filter nozzle, allowing air to enter and equalize pressure, while a cleaning cloth absorbs liquid, controlling discharge rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air inlet is located in the upper part of the liquid container to equalize air pressure inside and outside the container, then the liquid can flow out smoothly under gravity, but excessive liquid discharging occurs leading to poor cleaning effect and potential damage
Solution Approach 1:
The liquid container is divided into multiple compartments with separate liquid outlets for different cleaning areas. This segmentation allows independent control of liquid discharge to different regions, preventing excessive liquid discharge to any single area while ensuring adequate coverage across multiple zones.
Solution Approach 2:
Different regions of the liquid container bottom are equipped with liquid outlets of different sizes and discharge characteristics. The local quality of liquid discharge is optimized by matching outlet characteristics to the specific cleaning requirements of each area, thereby controlling excessive liquid discharge while maintaining smooth flow where needed.
2Productivity
If the liquid outlet is positioned at the bottom of the liquid container to utilize gravity for liquid discharge, then liquid can flow out continuously, but the liquid discharge rate cannot be controlled leading to waste of cleaning solution
Solution Approach 1:
The liquid outlet is designed with adjustable opening mechanisms that allow dynamic control of the discharge rate. The outlet can adapt its opening size based on cleaning needs, enabling continuous liquid flow when required while preventing excessive discharge and waste of cleaning solution.
Solution Approach 2:
The liquid discharge system incorporates feedback mechanisms that monitor liquid flow and adjust the outlet opening accordingly. This feedback control ensures optimal liquid discharge efficiency while preventing excessive flow that would lead to cleaning solution waste.
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
This design effectively manages liquid discharge, improving cleaning efficiency and preventing damage by maintaining internal and external pressure equilibrium, ensuring controlled liquid flow and reduced wear on components.
Implementation Method 1
an upper part of the liquid container is provided with an air inlet to facilitate liquid output. The air inlet may be located in the upper part of the liquid container to connect air inside and outside the liquid container, so that air pressure in the liquid container is approximately equal to the atmospheric pressure
Implementation Method 2
liquid constantly flows out of the liquid container under its own gravity, resulting in excessive liquid discharging
Implementation Method 3
the liquid container is shaped to facilitate air entered the liquid container through the air inlet moving to above a surface of liquid in the liquid container
Implementation Method 4
a cleaning cloth is attached to the bottom of the liquid container, and the cleaning cloth is configured to absorb liquid in the liquid container from the liquid outlet
