Body Paint Using Core-Shell Toner Particles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional body paints are often water-active, alcohol-based, costly, difficult to remove, prone to cracking, and require hair spray to fix colors, leading to uneven applications and bleeding.
Innovation Solution
A washable, non-toxic body paint using core/shell toner particles with a size range of 4.0 μm to 30 μm, where the core comprises a colorant and the shell is made of polyester resin, combined with an alcohol-free medium such as gelatin or glycerin, providing a smooth, long-lasting, and easy-to-apply solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water-active body paint is used, then the paint can be applied easily, but it requires rubbing on the skin and may crack or drip over time
Solution Approach 1:
The patent changes the physical and chemical parameters of the body paint by using toner particles with specific size ranges (4.0-30 μm) and combining them with alcohol-free mediums (gelatin or glycerin) in specific weight percentages (10-80%). This parameter optimization allows the paint to maintain stability without cracking or dripping while remaining easy to apply.
Solution Approach 2:
The patent creates a composite body paint system combining toner particles (core/shell structure with polyester resin shell) with alcohol-free mediums. This composite formulation provides both ease of application and long-term stability, eliminating the cracking and dripping issues of conventional water-active paints.
2Manufacturing precision
If alcohol-based body paint is used, then the paint has good coverage, but it is not easy to remove and is costly
Solution Approach 1:
The patent changes the chemical composition parameter by replacing alcohol-based mediums with alcohol-free alternatives (gelatin or glycerin). This substitution maintains good color coverage while significantly improving ease of removal, as the paint can be washed off with soap and water without requiring harsh solvents.
3Adaptability or versatility
If multiple colors are applied together, then creative expression is enabled, but the colors bleed into each other requiring hair spray to fix
Solution Approach 1:
The patent optimizes the particle size parameter of toner particles (4.0-30 μm) and the composition of alcohol-free medium to create a paint formulation where colors remain distinct when layered. The specific particle size and medium composition prevent bleeding between colors while maintaining the ability to apply multiple layers for creative effects.
