Cosmetic Container Fixing Structure for Convex Impregnation Member Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic containers with impregnation members struggle to stably accommodate impregnation members of varying shapes, particularly those with a convex shape, leading to instability and difficulty in preventing the impregnation member from coming out of the container.
Innovation Solution
A cosmetic container design featuring an outer container with a first accommodating portion and an inner container with a second accommodating portion, where the inner container is detachably coupled to the outer container and equipped with a coupling portion that includes a first and second fixing portion to securely hold the impregnation member in place, even if it has a convex shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a ring-shaped fixer with a horizontal step is used to accommodate the impregnation member, then the structure is simple and easy to manufacture, but it cannot effectively support impregnation members with convex shapes, leading to instability
Solution Approach 1:
The fixer is divided into multiple fixing portions (first fixing portion and second fixing portion) with different functions. The first fixing portion provides horizontal support while the second fixing portion provides vertical support, creating a segmented approach to stabilizing the impregnation member that accommodates various shapes including convex shapes.
Solution Approach 2:
The fixer transitions from a single horizontal step structure to a multi-dimensional structure with fixing portions extending in both horizontal and vertical directions. The second fixing portion extends downward from the lower surface of the first fixing portion, adding vertical dimensionality to effectively support convex-shaped impregnation members.
2Ease of operation
If the inner container is made detachable from the outer container for easy replacement of the impregnation member, then the ease of operation is improved, but the structural complexity increases
Solution Approach 1:
The container is segmented into an inner container and an outer container that can be separately assembled and disassembled. The inner container includes a coupling portion with fixing portions that can be independently configured, allowing for easy replacement of the impregnation member while maintaining a relatively simple overall structure through modular design.

AI summary
An embodiment of the present invention provides a cosmetic container. The cosmetic container includes an outer container in which a first accommodating portion is formed, an inner container in which a second accommodating portion, in which an impregnation member impregnated with a cosmetic material is accommodated, is formed and which is detachably coupled to an inner side of the first accommodating portion of the outer container, and a coupling portion which is coupled to a circumference of the second accommodating portion and which has a first fixing portion formed to extend downward from one side of an upper surface toward an inner side of the second accommodating portion to prevent the impregnation member from coming out of the second accommodating portion.
