Sliding Cosmetic Case with Inclined Protrusion for Mirror and Brush Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional color cosmetic cases are prone to noise and cosmetic material contamination due to the lack of proper fixation for the makeup brush, and the cover opening mechanism can cause accidental damage to cake-type cosmetics, with the brush being inconvenient to draw and often falling during use.
Innovation Solution
A sliding color cosmetic case design featuring a lower sliding member with an inclined protrusion member and a sliding cover, where the inclined protrusion member can be slantly erected to expose a mirror and facilitate easy access to the application tip, with a spring mechanism and notched protrusions to secure and retrieve the application tip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the makeup brush is not fixed in the case body, then the case structure remains simple, but the makeup brush collides against the inner surface causing noise and contamination
Solution Approach 1:
The lower sliding member automatically slides to the extended position when the upper housing is opened, causing the inclined protrusion member to erect and fix the application tip in an accessible position without requiring manual intervention. The system serves itself by using the opening action to trigger the fixing mechanism.
Solution Approach 2:
The application tip transitions from a stored horizontal position to an erected fixed position through the sliding action of the lower sliding member. The inclined protrusion member enables dynamic positioning that adapts between compact storage and accessible usage states.
2Ease of operation
If the cover is opened by hand, then the user can access the cosmetics, but the cake type cosmetics may be cracked due to impacts when the hand slips
Solution Approach 1:
The manual cover opening action is replaced by a sliding mechanism that uses the relative movement between the upper housing and lower sliding member to open the cover. This mechanical substitution eliminates the risk of hand slippage and impacts to the cosmetics.
Solution Approach 2:
The sliding cover member acts as an intermediary between the user's opening action and the cosmetic materials. Instead of directly exposing the cosmetics to potential impacts, the sliding mechanism provides a controlled, impact-free opening process.
3Ease of operation
If the application tip is built in the inclined protrusion member, then the mirror can be seen well when erected, but the structure becomes more complex
Solution Approach 1:
The application tip storage function and the mirror support function are merged into a single inclined protrusion member. This integration achieves multiple functions (storage, display, and mirroring) without proportionally increasing structural complexity.
Solution Approach 2:
The inclined protrusion member serves multiple purposes: it stores the application tip, provides a visible mirror surface, and acts as a guide for the sliding mechanism. This multi-functionality reduces the need for separate components.
4Ease of operation
If the makeup brush is drawn by insertion of fingers into the case body, then the brush can be accessed, but the brush may fall to the floor and become contaminated
Solution Approach 1:
The lower sliding member automatically extends and erects the application tip before the user needs to use it, positioning it in an easily accessible location. This preliminary action eliminates the need to reach into the case body, preventing contamination.
Solution Approach 2:
The system automatically presents the application tip in an accessible, clean position through the sliding mechanism, eliminating the need for the user to manually reach into the case and potentially contaminate it.

AI summary
Proposed is a sliding color cosmetic case comprising a lower sliding member, a color cosmetic case, an inclined protrusion member, and a sliding cover member. According to the present invention, when the lower sliding member of the color cosmetic case slides to one side, a mirror cover in which an application tip is embedded stands tilted so as to allow a user to easily see a mirror and easily take out the application tip.
