Deformable Lid Containing Liquid Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid storage containers face the challenge of liquid dispersion when the lid member is detached, due to liquid sticking to the lid member and being dispersed upon removal.
Innovation Solution
The liquid storage container design includes a lid member with a covering portion and a knob portion that can deform into a convex shape when pushed inward and into a concave shape when pulled outward, effectively containing any liquid that may stick to the lid member during detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stopper member is fit tightly to the liquid injecting port, then the sealing performance is improved, but liquid disperses to the surroundings when the stopper member is detached
Solution Approach 1:
A guide member is introduced as an intermediary component between the stopper member and the liquid injecting port. The guide member includes a guide portion that guides the stopper member during detachment, preventing liquid from dispersing while maintaining the tight fit for sealing. This mediator resolves the contradiction by providing a controlled path for stopper removal.
Solution Approach 2:
The lid member is divided into multiple functional segments: a stopper member for sealing, a guide member for controlled detachment, and a covering portion for protection. This segmentation allows each component to perform its specific function - the stopper maintains sealing, the guide prevents liquid dispersion during removal, and the covering portion protects the opening.
2Volume of moving object
If the lid member is designed with deformation capability, then the compact size is achieved, but the structural complexity increases
Solution Approach 1:
The covering portion is designed with dynamic deformation capability, allowing it to change shape between convex and concave forms. This dynamic structure enables the lid member to be pushed toward the inside to deform into a convex shape for compact storage, and pulled outward to deform into a concave shape for liquid containment, achieving space efficiency without adding complex mechanical components.
Solution Approach 2:
The lid member utilizes parameter changes in its shape and volume through deformation. By changing the shape parameter of the covering portion between convex and concave states, the overall volume of the liquid storage container is reduced while maintaining the functional capability to contain liquid during detachment operations.

Function Achieved in This Case
This design significantly reduces the possibility of liquid dispersion when the lid member is detached, while also allowing for a more compact size of the liquid storage container and the associated ejection apparatus.
Implementation Method 1
the covering portion can deform into a convex shape in a case where the knob portion is pushed toward the inside from the outside of the opening in a state where the lid member is attached to the opening and can deform from the convex shape into a concave shape in a case where the knob portion is pulled up toward the outside from the inside of the opening

AI summary
An object is to provide a liquid storage container capable of reducing the possibility of dispersion of liquid in a case where a lid member is detached. The lid member has a covering portion capable of covering the opening and a knob portion protruding from the covering portion in a direction in which the knob portion becomes more distant from the opening. The covering portion can deform into a convex shape in a case where the knob portion is pushed toward the inside from the outside of the opening in a state where the lid member is attached to the opening and can deform from the convex shape into a concave shape in a case where the knob portion is pulled up toward the outside from the inside of the opening in a state where the covering portion has deformed into the convex shape.
