Dual End Cosmetic Container Nested Cups Threaded Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional dual cosmetic containers are bulky due to the need for two distinct mechanisms, occupying excessive space in personal items like handbags.
Innovation Solution
A dual end container with a compact, integrated mechanism featuring a first cup and a second cup aligned along a longitudinal axis, where the second cup is at least partially housed within the first cup, and a driving member assembly with threaded members allows for selective extension and retraction of each product without moving the other, using a first male thread interacting with a first female thread and a second male thread interacting with a second female thread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two distinct mechanisms are used for each cosmetic product, then each product can be extended and retracted independently, but the container becomes bulky and occupies excessive space
Solution Approach 1:
The second cup is nested within the first cup, with the second cup's outer surface having a diameter less than the first cup's interior volume. This nesting arrangement allows both products to be housed in a compact configuration, reducing the overall container volume while maintaining independent extendability of each cup through its own threaded mechanism.
2Volume of moving object
If a compact integrated mechanism is used, then the container size is reduced, but the complexity of the driving member assembly increases
Solution Approach 1:
The driving member assembly is segmented into a first driving member with a first threaded member for the first cup, and a second driving member with a second threaded member for the second cup. The second driving member is disposed within the interior volume of the first threaded member. This segmentation allows each cup to be controlled independently through its own driving member and threaded mechanism, simplifying the overall control structure while achieving compact integration.
3Volume of moving object
If the second cup is housed within the first cup, then space is optimized, but the manufacturing precision requirements increase
Solution Approach 1:
The driving member assembly is divided into separate first and second driving members, each with its own threaded member. The first threaded member has an interior volume that accommodates the second threaded member. This segmentation allows each threaded mechanism to be manufactured and assembled independently, reducing the cumulative precision requirements compared to a single integrated threaded system, while still achieving the compact nested configuration.
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 solution reduces the overall length of the container by integrating both extension and retraction mechanisms, allowing independent use of products from opposite ends without accidental actuation, thus optimizing space and user convenience.
Implementation Method 1
The first male thread interacts with the first female thread to extend and retract the first cup
Implementation Method 2
The second male thread interacts with the second female thread to extend and retract the second cup

AI summary
A dual end container for products such as cosmetics provided. Specifically, a dual end container with a compact, integrated mechanism for selectively extending and retracting a first product or applicator without movement of a second product or applicator is disclosed. The dual end container includes a first cup, a second cup, which is at least partially housed within the first cup, and a driving member assembly, which includes a first driving member and a second driving member, between the first cup and the second cup. The first cup has a first male thread, the second cup has a second male thread, the first driving member has a first female thread, and the second driving member has a second female thread. The male threads interact with the corresponding female threads to extend and retract the corresponding cups.
