Liquid container, and electrostatic atomizing apparatus with liquid container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In aircraft environments, the vibration during take-off and landing causes water in liquid containers to splash or form waves, leading to potential leakage through openings, which can result in electric leaks or short circuits in nearby electronic devices.
Innovation Solution
A liquid container with a detachable design featuring a container main body, ventilation holes, and a pivotable lid that adjusts based on the water surface, combined with a duct member and detachment mechanism to secure airflow and prevent water leakage, is integrated into an electrostatic atomizing apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the container has openings for air flow, then humidification function is enabled, but water leakage occurs during vibration
Solution Approach 1:
The lid is designed to dynamically adjust its position based on liquid level changes during aircraft vibration. The pivotable connection allows the lid to automatically open when liquid level rises and close when it falls, enabling the container to adapt to varying vibration conditions and maintain both airflow function and leakage prevention.
Solution Approach 2:
The container opening state changes based on the parameter of liquid level height. During normal operation, the opening remains open for airflow. When vibration causes liquid level to rise, the opening closes to prevent leakage. This parameter-based state change resolves the contradiction between needing open airflow and preventing leakage.
2Reliability
If the lid is fixed closed to prevent leakage, then water leakage is prevented, but air flow path is blocked
Solution Approach 1:
The lid transitions from a static fixed structure to a dynamic pivotable component that can switch between open and closed states. This dynamic capability allows the lid to remain open during normal operation for airflow, and automatically close only when vibration causes liquid level to rise, thus maintaining airflow path while preventing leakage when needed.
3Reliability
If the lid is positioned far from the side to close the ventilation hole, then sealing is improved, but air flow restriction increases
Solution Approach 1:
The lid closes the ventilation hole only partially or temporarily - specifically when vibration causes liquid level to rise. During normal operation, the lid remains open to allow full airflow. This partial closing action provides sufficient sealing to prevent leakage during vibration while minimizing restriction of airflow during normal humidification operation.
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 effectively secures the airflow path for humidification while preventing water leakage, even during aircraft vibrations, reducing the risk of electric leaks and ensuring continuous operation of the electrostatic atomizing apparatus.
Implementation Method 1
The lid is capable of closing or opening the ventilation hole according to a change in a surface of the liquid

AI summary
The liquid container according to the present disclosure is a liquid container to be detachably attached to the main body portion of an apparatus. The liquid container includes a container main body, a ventilation hole, and a lid. The container main body includes an upper portion, a bottom portion, and side portions connecting the upper portion and the bottom portion. The container main body is capable of storing a liquid. The ventilation hole penetrates the upper portion of the container main body. The lid is disposed on an inner side of the container main body and, when the liquid is stored in the container main body, is capable of closing or opening the ventilation hole according to a change in a surface of the liquid. The lid includes a fulcrum positioned closer to the side portion of the container main body than to the ventilation hole. The lid is pivotable around the fulcrum with respect to the ventilation hole.
