Cosmetic Container with Double-Groove Slideways for Complete Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cosmetic containers suffer from low utilization rates of the material body, user experience issues, and reduced service life due to the inability to fully use the contents, often requiring harder materials to prevent breakage when exposed.
Innovation Solution
A cosmetic container design featuring a threaded sleeve with double helix guide grooves, a rotating member with slideway patterns, and a material cup and pushing cup that allow synchronized and independent ascension/descension through overlapping slideways, enabling complete use of the material body and allowing softer materials without breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If most of the material body is placed in the cup body, then the material body needs to be made of a harder material, but this reduces user experience
Solution Approach 1:
The cup body is divided into a first cup body and a second cup body that can move relative to each other. The material body is segmented between these two cup bodies, with part in the first cup body and part extendable through the second cup body. This segmentation allows the material body to be softer (improving user experience) while still being protected during storage in the first cup body.
Solution Approach 2:
The second cup body is designed to move relative to the first cup body, transitioning between a first position (where material body is protected) and a second position (where material body is extendable). This dynamic structure allows the system to adapt between protection and accessibility, improving user experience without compromising reliability.
2Ease of operation
If most of the material body sticks out of the cup body, then user accessibility is improved, but the material body easily breaks and service life is reduced
Solution Approach 1:
The cup body is segmented into movable first and second cup bodies, allowing the material body to be partially stored in the first cup body (protected) and partially extendable through the second cup body (accessible). This segmentation enables the material body to maintain both protection and accessibility simultaneously.
Solution Approach 2:
The second cup body is nested within or relative to the first cup body, creating a nested structure where the material body can be progressively exposed. This nested arrangement allows the material body to be protected when needed and accessible when needed, extending service life while maintaining usability.
3Ease of operation
If the cup body is completely ascended, then some material body remains in the cup body, but this results in waste and low utilization rate
Solution Approach 1:
The second cup body moves dynamically between positions, allowing the material body to be completely dispensed when the second cup body reaches its second position. This dynamic design ensures that no material body is left behind in the first cup body, achieving complete utilization and eliminating waste.
Solution Approach 2:
The movable second cup body enables continuous access to the material body from the first cup body, ensuring that the entire material body can be used without interruption or leftover portions. This continuity of useful action eliminates the waste associated with traditional fixed cup body designs.

AI summary
A cosmetic container and a method for using the same. The cosmetic container includes: a threaded sleeve with an inner wall having a first guide groove and a second guide groove; a rotating member rotatably sleeved in the threaded sleeve, with a side wall having a slideway pattern; a material cup slidably sleeved in the rotating member, with a side wall having a third slideway and at least one first lug passing through the slideway pattern and limited in the first guide groove; and a pushing cup slidably sleeved in the material cup, with a side wall having at least one second lug passing successively through the third slideway and the slideway pattern and limited in the second guide groove. The cosmetic container enables a material body contained in it to be used up and is easy to operate.
