Linked Cosmetic Case Sliding Mechanism for Simultaneous Container Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic cases are inconvenient for users to open and close, especially when multitasking or for individuals with physical challenges, as they require separate operation of multiple containers and lack a built-in mirror for easy makeup application.
Innovation Solution
A cosmetic case design featuring interconnected casings that allow simultaneous opening and closing of containers with a sliding mechanism, accompanied by a lift mechanism for the third casing, which includes a mirror for convenient viewing, utilizing guide rails and elastic members for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple containers are included in the cosmetic case, then the functionality and versatility are improved, but the complexity of opening and closing operations increases
Solution Approach 1:
The patent combines multiple container opening operations into a single unified action. When the user slides the second casing to open the first container, the linkage mechanism automatically triggers the opening of the second container as well, merging two separate operations into one coordinated action, thus reducing operational complexity while maintaining multiple container functionality
Solution Approach 2:
The linkage mechanism is pre-configured so that the opening of the first container automatically precipitates the opening of the second container. This preliminary mechanical arrangement ensures that both containers are opened in sequence without requiring separate user actions, thereby simplifying the overall operation while preserving versatility
2Ease of operation
If the cosmetic case structure is simplified, then the ease of operation is improved, but the functionality to accommodate multiple containers is reduced
Solution Approach 1:
The patent employs a nested structure where the second container is positioned within the second casing, which itself is part of the first casing assembly. This nesting arrangement allows multiple containers to be accommodated in a compact configuration, maintaining ease of operation through a single sliding action while preserving the functionality to hold multiple separate container units
3Ease of operation
If a mirror is added to the cosmetic case, then the ease of makeup application is improved, but the device complexity increases
Solution Approach 1:
The mirror is integrated into the third casing, which serves multiple functions: it acts as a cover for the second container, provides a reflective surface for makeup application, and incorporates a linkage mechanism for coordinated opening. This multi-functionality approach adds the mirror feature without proportionally increasing structural complexity, as the mirror serves both aesthetic and mechanical purposes within the existing framework

AI summary
A cosmetic case is provided. The cosmetic case includes: a first casing having a first container; a second casing which is connected with the first casing in a sliding manner, opens and closes the first container, and has a second container; and a third casing which is connected with the second casing, and opens and closes the second container, wherein, when the first container is open by sliding the second casing with respect to the first casing, the third casing is lifted at the same time, thereby opening the second container.
