Flexible Cap Dropper for Cosmetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetics containers are inconvenient to use, as they require constant dipping, leading to cosmetic deterioration and inaccurate control over the amount applied, especially for products with strong chemical activity.
Innovation Solution
A cosmetics container equipped with a flexible cap that generates a suction force when deformed, allowing controlled dispensing of cosmetics through a cotton or brush head component, protecting the product from air exposure and enabling precise application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional bottle with dipping head is used, then the container structure is simple, but the cosmetics are constantly exposed to air causing deterioration and the amount of dipping cannot be controlled accurately
Solution Approach 1:
The dropper is divided into separate functional components: a flexible cap for suction, a hollow tube body for holding cosmetics, and a head component for application. This segmentation allows the cosmetics to be isolated from air until needed, improving stability while maintaining a manageable structure.
Solution Approach 2:
The flexible cap acts as an intermediary mechanism between the user and the cosmetics. By deforming the cap, the user creates negative pressure to suction cosmetics into the tube body, then controls the release of cosmetics through the head component, preventing direct air exposure and enabling precise amount control.
2Ease of operation
If constant dipping is used to apply cosmetics, then the operation is simple, but the cosmetics deteriorate due to air contact and the dipping amount cannot be controlled
Solution Approach 1:
The user first deforms the flexible cap to suction the required amount of cosmetics into the tube body before application. This preliminary action isolates the cosmetics from air contact during storage and allows precise control of the amount to be applied, improving both convenience and stability.
Solution Approach 2:
The application process occurs in periodic cycles: deform cap to suction cosmetics, release cap to allow controlled flow through head component, then repeat when needed. This periodic action minimizes air exposure time and allows precise control over when and how much cosmetic is applied.
3Quantity of substance
If a rigid cap is used, then the cap structure is simple, but it cannot generate suction force for cosmetic absorption
Solution Approach 1:
The cap is designed as flexible rather than rigid, allowing it to be dynamically deformed by the user. When the flexible cap is compressed and released, it creates negative pressure that sucks cosmetics into the tube body. This dynamic flexibility enables suction functionality while keeping the cap structure simple and integrated.
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 container provides a convenient, portable solution for controlled cosmetic dispensing, protecting the product from deterioration and allowing accurate application, suitable for various cosmetics like lip gloss and eye liner.
Implementation Method 1
the flexible cap needs to achieve a function that the flexile cap may be deformed when being pressed, being extruded and being under other operations, and generate a certain suction force when being deformed
