Inside Plug with Movable Section for Liquid Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid evaporating/diffusing devices with inside plugs lacking ventilation structures face issues with non-uniform volatilization rates and potential liquid leakage due to changes in atmospheric pressure, which can lead to liquid leakage when the container falls sideways.
Innovation Solution
An inside plug with a movable section and a through hole on the liquid-side surface that communicates with the container's inner space, allowing air to flow and preventing liquid leakage by utilizing capillary action to fill the through hole with liquid when the container falls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a ventilation hole is provided in the inside plug, then atmospheric pressure stability is improved, but liquid leakage occurs when the container falls sideways
Solution Approach 1:
The patent applies the dynamics principle by making the inside plug movable rather than fixed. The inside plug can move vertically within the container opening, allowing it to dynamically adjust its position. When the container is upright, the plug maintains a position that allows ventilation. When the container falls sideways, gravity causes the plug to move and block the ventilation hole, preventing liquid leakage. This dynamic adjustment resolves the contradiction between maintaining atmospheric pressure stability and preventing liquid leakage.
2Reliability
If the inside plug is fixed without a ventilation structure, then liquid leakage is prevented, but volatilization rate becomes non-uniform due to pressure changes
Solution Approach 1:
The movable inside plug enables the system to dynamically switch between two states: when upright, the plug allows ventilation holes to open for pressure equalization, ensuring uniform volatilization; when tilted, the plug moves to block the holes, preventing leakage. This dynamic behavior resolves the contradiction between preventing leakage and maintaining uniform volatilization rate.
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 stabilizes internal pressure, prevents uneven diffusion rates, and effectively blocks air flow through the through hole, thereby preventing liquid leakage from the container.
Implementation Method 1
a liquid (e.g., an aromatic etc.) stored in a container body is evaporated and diffused to an outside of the container body by utilizing capillary action which is caused by a liquid absorbent wick
Implementation Method 2
the movable section being brought closer to the liquid-side surface by gravity in a case where the suction-type liquid container has fallen sideways
