Screen Mesh Cosmetic Absorber for Controlled Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetics with liquid contents face challenges in controlling the ejection amount and structural deformation due to varying absorber materials and reactions, leading to inconsistent product usage and user experience.
Innovation Solution
A cosmetic design incorporating a screen net with specific materials like polyurethane, thermoplastic elastomer, and polyester, with holes of 0.01-1.0 mm, adjacent to an absorber, allowing controlled ejection and minimizing structural deformation through high-frequency or ultrasonic fusion with a screen net frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a net structure with mesh size of 3-5 mm or greater is used to allow content to stick to a puff, then the content can be ejected as desired, but the mesh size is too large to provide precise control over ejection amount
Solution Approach 1:
The invention divides the ejection control function into two parts: the absorber material controls the release of content, while the screen net with fine mesh (0.01-1.0 mm) controls the ejection amount. This segmentation allows precise control by separating the absorption function from the ejection control function, resolving the contradiction between adequate content release and precise ejection control.
2Quantity of substance
If an absorber absorbs an excessively large amount of liquid content, then the absorber can provide sufficient content for use, but the absorber's ability of controlling the ejection of the content is lost
Solution Approach 1:
The screen net acts as an intermediary between the absorber and the external environment. It mediates the ejection process by controlling the amount of content that can be ejected from the absorber, thereby maintaining control ability even when the absorber contains a large amount of liquid content.
3Adaptability or versatility
If an absorber is used that reacts with the liquid content, then the absorber may increase in volume, but this results in structural deformation and mismatch with the container
Solution Approach 1:
The screen net provides preliminary structural support to counteract the swelling of the absorber when it reacts with the liquid content. By placing the rigid screen net adjacent to the absorber, the invention prevents structural deformation before it occurs, maintaining both adaptability to various absorber materials and structural stability.
4Measurement precision
If the absorber ejects a relatively small amount of content, then the ejection is well-controlled, but customers will complain that the amount of content that can be used is too small
Solution Approach 1:
The combination of the absorber and screen net enables continuous ejection of content at a controlled rate. The absorber can store a large amount of liquid content while the screen net ensures steady, controlled ejection, maintaining both precision control and sufficient total content availability for extended use.
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
