Memory Foam Cosmetic Blender for Hygienic Low-Waste Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic blenders made of open-cell foam are inefficient in terms of material usage, hygiene, and cleaning, as they absorb excessive makeup, lead to bacterial growth, and are not suitable for rapid cleaning and drying, especially when used with microbiome cosmetics.
Innovation Solution
A cosmetic applicator with a resilient body featuring a patterned surface comprising distinct porous and non-porous areas, a removable foam layer, and actuators for controlled tamping, along with a fluid-impermeable core, enabling precise makeup application, efficient cleaning, and integration with smart technology for optimized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If open-cell foam blenders are used to pick up and release cosmetic material, then blending capability is improved, but excessive cosmetic material is impregnated into the sponge causing waste and cleaning difficulties
Solution Approach 1:
The blender is divided into two distinct functional zones: a first zone with open-cell foam structure for picking up cosmetic material, and a second zone with closed-cell foam structure for releasing and blending the material. This segmentation allows each zone to perform its specific function efficiently without excessive material impregnation throughout the entire sponge.
Solution Approach 2:
Different regions of the blender are assigned different foam structures tailored to their specific functions. The first zone uses open-cell foam optimized for material pickup, while the second zone uses closed-cell foam optimized for controlled release and blending, creating local quality variations that improve overall performance and reduce waste.
2Quantity of substance
If small pore size foam is used to hold water for moisturization, then moisture retention is improved, but cleaning becomes problematic and drying time increases to hours
Solution Approach 1:
The blender incorporates a removable surface component with limited-volume open cells for moisture holding, separated from the main body. This allows the moisture-retention function to be concentrated in a small, easily cleanable component rather than throughout the entire blender, significantly reducing drying time.
Solution Approach 2:
The open-cell moisture-retaining structure is extracted as a separate removable surface component that can be easily removed for cleaning. This extraction allows rapid rinsing and drying of the moisture-holding portion without having to clean the entire blender, reducing drying time from hours to minutes.
3Ease of operation
If liquid cosmetic material permeates through the entire foam body, then blending coverage is improved, but bacterial growth is facilitated inside the pores
Solution Approach 1:
The blender is segmented into a first zone for material pickup and a second zone for blending, with the second zone using closed-cell foam that prevents liquid cosmetic material from permeating deep into the structure. This segmentation limits bacterial growth zones while maintaining blending coverage.
Solution Approach 2:
The patent uses open-cell foam only in the first zone for controlled material pickup, while the second zone uses closed-cell foam that resists liquid permeation. This selective use of porous materials allows blending coverage while preventing bacterial growth in the closed-cell region where liquid does not penetrate.
4Ease of manufacture
If uniform density foam is used for the entire blender, then manufacturing simplicity is maintained, but different areas of the face require different force/compression characteristics
Solution Approach 1:
The blender incorporates zones with different foam densities and compression characteristics tailored to specific facial areas. The first zone has softer foam for delicate areas like around the eyes, while the second zone has firmer foam for broader blending areas, providing adaptability without sacrificing manufacturability through modular design.
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 allows for rapid and hygienic makeup application, reduces waste, prevents bacterial growth, and effectively handles microbiome cosmetics by controlling moisture and force characteristics, enhancing blending efficiency and user experience.
Implementation Method 1
cosmetic materials, such as contour makeup 60 (FIG. 3), are picked up by open cells of the blender surface and then released back onto the skin surface as the blender is moved
Implementation Method 2
the uniformity of the resilient open cell foam material and the slow rebound of such memory foam from a compressed or tensioned state to its repose memory shape
