Cosmetic Container Rack Bar Gear Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic containers are inconvenient to use quickly, often requiring two hands and can become stuck after long-term use, failing to meet the need for rapid access and smooth operation.
Innovation Solution
A cosmetic container design featuring a rotating holder with a gear and a lifting holder containing a rack bar and support holder, where the rack bar is lubricated and engages with the gear for easy upward or downward movement, allowing single-handed use and preventing unintentional movement of cosmetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotating tube structure is used for cosmetic containers, then the cosmetic can be extended and retracted, but the structure becomes complicated and the operation becomes inconvenient requiring two hands
Solution Approach 1:
The cosmetic container is divided into separate functional modules: a fixed body housing, a removable support holder for the cosmetic, and a simple rack-bar mechanism. This segmentation eliminates the need for complex rotating tube structures while maintaining the extend and retract function through modular components that work together independently.
Solution Approach 2:
The invention extracts the essential function of extending and retracting cosmetics from the complex rotating tube mechanism. By removing the rotating tube structure entirely and keeping only the body and support holder with a simple rack-bar system, the design achieves the same functional outcome with significantly reduced structural complexity and one-handed operability.
2Reliability
If a rotating tube structure is used, then the cosmetic can be extended, but the rotating parts may get stuck after long-term use causing non-smooth rotation
Solution Approach 1:
The lubricating device integrates the oil cavity, clamping piece, and rack bar into a unified lubrication system. The oil cavity is positioned to directly contact the rack bar, and the clamping piece secures the rack bar while allowing it to move smoothly. This merged structure ensures continuous lubrication of the moving parts, preventing them from getting stuck after long-term use and maintaining reliable smooth operation.
Solution Approach 2:
The lubricating device is designed to automatically lubricate the rack bar during normal operation. As the rack bar moves within the rotating holder, it passes through the oil cavity which provides continuous lubrication without requiring user intervention. This self-service lubrication system prevents wear and sticking, ensuring long-term reliability and smooth operation.
3Device complexity
If a simple rotating tube structure is used, then the structure is simple, but it cannot provide continuous lubrication leading to friction and wear
Solution Approach 1:
The lubricating device acts as an intermediary element between the rack bar and the rotating holder. The oil cavity serves as the medium that introduces lubrication into the system, reducing friction between the rack bar and surrounding structures. This intermediary lubrication system is integrated into the simple overall design, adding friction resistance without significantly increasing structural complexity.
