Cosmetics Container Piston Guide Tube Sweeps Residue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers fail to prevent leftover cosmetics, especially those with high viscosity, from adhering to the inner walls, leading to waste and deterioration when the cap is removed, and they often leak when stored upside down.
Innovation Solution
A cosmetic container design featuring a rotating member with a cosmetics guide tube and a screw-coupled piston that pushes cosmetics into the guide tube for efficient use and application without a brush rod, ensuring an airtight seal and preventing leftovers by sweeping cosmetics off the inner surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a conventional cosmetic container with a cap and brush rod is used, then the container can be opened for application, but cosmetics remain on the inner wall and cannot be entirely used, causing waste
Solution Approach 1:
The patent introduces a rotating member that can rotate within the container body, dynamically changing the position of the piston and guide tube to push cosmetics from the inner wall toward the applicator, enabling complete utilization of cosmetics while maintaining ease of application
Solution Approach 2:
The piston acts as an intermediary component between the rotating member and the cosmetics, transmitting the rotational motion to push cosmetics along the guide tube toward the applicator, thereby preventing cosmetics from remaining on the inner wall
2Reliability
If the cap is removed from the container, then cosmetics can be applied, but cosmetics remaining on the inner wall are continuously exposed to the outside and deteriorate or harden
Solution Approach 1:
The rotating member and piston mechanism performs preliminary action by continuously pushing cosmetics toward the applicator before the cap is removed, ensuring cosmetics are ready for application and preventing deterioration by minimizing exposure time
Solution Approach 2:
The rotating member enables continuous action by repeatedly pushing cosmetics from the inner wall toward the applicator, maintaining cosmetics in a ready state and preventing prolonged exposure to air that would cause deterioration or hardening
3Loss of substance
If a piston is added to push cosmetics, then cosmetics can be completely used, but the device structure becomes more complex
Solution Approach 1:
The patent merges the piston, guide tube, and rotating member into an integrated assembly, where the piston is coupled to the guide tube which is coupled to the rotating member, reducing the number of separate components while achieving complete cosmetics utilization
Solution Approach 2:
The rotating member serves multiple functions: it rotates to drive the piston, guides the piston movement, and positions the guide tube to direct cosmetics flow, thereby reducing the need for additional separate components and simplifying the overall structure
4Ease of operation
If the brush rod is not inserted into the lower part of the container, then application is simplified, but cosmetics cannot be applied efficiently
Solution Approach 1:
The rotating member and piston mechanism performs self-service by automatically pushing cosmetics toward the applicator without requiring the brush rod to be inserted deep into the container, enabling efficient application while maintaining operational simplicity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design allows for complete use of cosmetics without leftovers and maintains an airtight seal, preventing waste and deterioration, while enabling convenient application even without inserting the brush rod to the bottom of the container.
Implementation Method 1
having threads formed on the outer periphery of the cosmetics guide tube so as to allow a piston to be screw-coupled to the outer side thereof such that the piston screw-coupled to the cosmetics guide tube of the rotating member pushes the cosmetics accommodated in the container main body up into the cosmetics guide tube
Implementation Method 2
moving downwards by the rotation of the rotating member
