Compact Cosmetic Container with Rotating Dish Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers are inconvenient and economically burdensome due to the need for separate containers for various cosmetics, and they suffer from poor sealing and susceptibility to external impacts that can contaminate contents.
Innovation Solution
A compact container with an improved opening/closing structure featuring a rotation dish coupling member and axial rotation parts that allow controlled rotation and locking of the rotation dish, preventing arbitrary opening and ensuring secure storage and use of multiple cosmetic contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rotation dish is simply rotated to be opened and closed, then the opening/closing operation is simple, but the rotation dish can be arbitrarily rotated by external impact, causing contents to be exposed and contaminated
Solution Approach 1:
The coupling structure transitions between locked and unlocked states dynamically. The axial rotation part and axial rotation hole are locked together during normal operation to prevent arbitrary rotation, but can be deliberately unlocked by pulling the rotation dish forward, allowing controlled opening and closing operations.
Solution Approach 2:
The coupling structure proactively prevents arbitrary rotation by maintaining a locked state during storage and transport. The axial rotation part and axial rotation hole are designed to engage automatically, creating preliminary protection against external impacts before they can cause contamination.
2Adaptability or versatility
If multiple cosmetic contents are stored in separate containers, then various cosmetics can be carried, but it is inconvenient to carry and economically burdensome
Solution Approach 1:
The rotation dish containing the second content is nested within the container body that holds the content container with the first content. This nested arrangement allows multiple cosmetic contents to be stored in a single compact container, eliminating the need for multiple separate containers and reducing carrying inconvenience.
Solution Approach 2:
The single compact container is designed to hold multiple different cosmetic contents (first content in content container, second content in rotation dish). This multi-functional design allows users to carry various cosmetics in one container rather than needing multiple specialized containers for each cosmetic type.
3Ease of operation
If the first container and second container are rotatably coupled, then opening and closing is convenient, but the sealing force is poor when storing volatile contents
Solution Approach 1:
The coupling structure transitions between locked and unlocked states dynamically. The axial rotation part and axial rotation hole are locked together during normal operation to prevent arbitrary rotation, but can be deliberately unlocked by pulling the rotation dish forward, allowing controlled opening and closing operations.
Solution Approach 2:
The axial rotation part features a curved surface that fits into the axial rotation hole. This curved geometry provides continuous contact and uniform distribution of locking force, enhancing the sealing effect while maintaining smooth rotational movement for opening and closing operations.
