Dual End Cosmetic Container Integrated Threaded Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional dual cosmetic containers are bulky due to the need for two distinct mechanisms, occupying excessive space.
Innovation Solution
A dual end container with a compact, integrated mechanism that allows selective extension and retraction of one product without moving the other, featuring a first cup, a second cup partially housed within the first, and a driving member with female and male threads for independent operation of each product.
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 independently extended and retracted, but the container becomes bulky and occupies excessive space
Solution Approach 1:
The patent combines two separate extension and retraction mechanisms into a single integrated driving member. The driving member includes a first threaded portion engaging with the first cup and a second threaded portion engaging with the second cup, allowing both cups to be extended and retracted through one unified mechanism rather than two distinct mechanisms, thereby reducing the overall container volume while maintaining independent operation capability
Solution Approach 2:
The patent implements a nested structure where the second cup is partially housed within the first cup, and the driving member is positioned between the two cups. This nesting arrangement allows the mechanisms to share space efficiently, with the second cup's mechanism nested within the spatial envelope of the first cup's mechanism, significantly reducing the bulk of the container
2Volume of moving object
If a compact integrated mechanism is used, then the container size is reduced, but the complexity of the mechanism increases
Solution Approach 1:
The driving member serves multiple functions simultaneously: it acts as the extension mechanism for the first cup through the first threaded portion, the extension mechanism for the second cup through the second threaded portion, and provides the structural framework for the entire dual-cup system. This multi-functionality reduces the need for separate components, simplifying the overall mechanism despite the integrated design
Solution Approach 2:
The driving member is segmented into distinct functional portions: a first threaded portion for engaging the first cup and a second threaded portion for engaging the second cup. This segmentation allows each portion to be optimized for its specific function while being part of a unified structure, managing complexity through functional division within the integrated mechanism
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, preventing accidental actuation of unwanted products and allowing independent access to desired cosmetic products.
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 cosmetic products or applicators is provided. More 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 between the first cup and the second cup. The first cup has a first male thread, the second cup has a second male thread and the driving member has a first and second female thread. The first male thread interacts with the first female thread to extend and retract the first cup. The second male thread interacts with the second female thread to extend and retract the second cup.
