Solid Cosmetic Surface Recesses and Protrusions for Precise Colorant Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solid cosmetics with decorative elements like powders or particles by dispersive adhesion lack sufficient product appeal and visual attractiveness.
Innovation Solution
A solid cosmetic with a surface featuring fine recesses and protrusions of varying heights and inclined surfaces, where a glossy colorant with primary particle diameters between 10 to 100 μm is dispersively adhered using a spray method, enhancing the cosmetic's visual appeal and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If powders or particles are added to the surfaces of solid cosmetics by dispersive adhesion, then eye catching properties are increased, but product appeal remains insufficient
Solution Approach 1:
The invention applies local quality by creating regions with fine recesses and protrusions at specific locations on the solid cosmetic surface, and selectively adding colorants to these specific regions. This localized approach enhances eye-catching properties in specific areas while maintaining overall product appeal, resolving the contradiction between localized visual enhancement and overall product versatility.
Solution Approach 2:
The invention transitions from two-dimensional surface decoration to three-dimensional surface structuring by creating fine recesses and protrusions with height differences of 0.01 to 10 μm. This dimensional change allows colorants to be trapped and held in the recesses, providing superior eye-catching properties and enhanced product appeal that cannot be achieved with conventional flat surface decoration.
2Manufacturing precision
If a spray method is used to disperse colorant onto the solid cosmetic surface, then precise coloration is achieved, but complexity of the process increases
Solution Approach 1:
The invention uses a spray method as an intermediary technique to deposit colorants onto the solid cosmetic surface. The spray process acts as a mediator that enables precise coloration by controlling the dispersion and placement of colorant particles in the recesses and protrusions, achieving high manufacturing precision while maintaining reasonable process complexity through the use of established spray technology.
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 method results in a more attractive and eye-catching cosmetic appearance with precise coloration of the surface features without bleeding or shifting, improving product appeal and visual appeal.
Implementation Method 1
a colorant with a primary particle diameter within a range from 10 to 100 μm is added to a portion of the upper surface of the solid cosmetic that includes at least a portion of the region of fine recesses and protrusions by dispersive adhesion

AI summary
A solid cosmetic which is held in a tray includes: a region of fine recesses and protrusions with differences in height within a range from 0.1 to 10 mm and that includes inclined surfaces formed on an upper surface of the solid cosmetic; and a colorant with a primary particle diameter within a range from 10 to 100 μm added to a portion of the upper surface of the solid cosmetic that includes at least a portion of the region of fine recesses and protrusions by dispersive adhesion.
