Container Inner Layer Separation Using Support Column
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for separating the inner layer from the outer layer in containers, such as ink cartridges, often result in excessive deformation of the inner layer, leading to wrinkles and poor restoration due to the exhaustion of air inside the inner layer, which degrades its integrity.
Innovation Solution
A method involving the use of a support column with a columnar portion and extending portions is introduced, where air is supplied through an air communication port to separate the inner layer from the outer layer, allowing the inner layer to come into contact with the support column, thereby minimizing deformation and facilitating restoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If air is blown between the outer layer and the inner layer to separate them, then the inner layer can be separated from the outer layer, but the inner layer undergoes excessive deformation causing wrinkles and folds
Solution Approach 1:
A support column is introduced as an intermediary object between the inner layer and the outer layer during the separation process. The support column provides physical support to the inner layer, preventing it from collapsing or deforming excessively when air is blown to separate the layers. The column maintains the inner layer's shape while allowing separation to occur.
Solution Approach 2:
The support column is positioned in advance within the inner layer before the separation process begins. This pre-positioning creates a cushioning effect that protects the inner layer from sudden deformation when air pressure is applied. The column acts as a buffer that distributes the mechanical stress during separation.
2Volume of stationary object
If air inside the inner layer is exhausted outside during separation, then the volume of the space inside the inner layer is reduced, but the inner layer cannot be sufficiently restored
Solution Approach 1:
The support column is inserted into the inner layer before the separation and air exhaustion processes occur. This preliminary action ensures that the inner layer has structural support throughout the entire sequence of operations - during separation, during air exhaustion, and during restoration. The column remains in place to maintain shape integrity at each stage.
Solution Approach 2:
The support column serves as a mediator that enables the air exhaustion process to occur without compromising the inner layer's restorability. By providing continuous structural support, the column allows the inner layer to be depleted of air and reduced in volume while preventing permanent deformation, thereby enabling subsequent restoration to the original shape.

Function Achieved in This Case

AI summary
Provided is a method for manufacturing a container including a casing configured to contain a content, the casing including an inner layer having an inner layer opening and an outer layer having an air communication port communicating between a space between the outer layer and the inner layer and the outside. The method includes preparing a casing in which at least part of the inner layer and at least part of the outer layer are in contact with each other, inserting a support column inside the inner layer through the inner layer opening of the prepared casing, and separating the inner layer from the outer layer by supplying air into the space through the air communication port to bring part of the separated inner layer into contact with the support column. The support column includes a columnar portion and an extending portion extending from the columnar portion.
