Solution Overview

Problem

Existing tattoo printing methods face challenges in achieving excellent printing quality on the skin due to issues like smudging and slow drying of water-based inks, which affect the skin absorption and adhesion of the ink.

Innovation Solution

A tattoo printing method and kit that include an ink fixer composition with a binder and spherical or plate-shaped powders, applied before or after the ink composition, to enhance skin absorption and drying speed, preventing smudging and improving print quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If water-based ink is printed directly on the skin, then the ink can be applied easily, but the ink smudges and does not dry quickly

Engineering Contradiction:
Improveease of ink applicationVSAvoidprint quality and ink fixation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a primer composition as an intermediary layer between the skin and the water-based ink. This primer contains powder particles (5-50 μm) and binder, creating a surface that improves ink absorption and prevents smudging. The primer acts as a mediator that enables water-based ink to dry quickly and adhere properly on the skin without requiring complex equipment or harsh chemicals.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If water-based ink is used for skin printing, then the ink is harmless and easy to apply, but the infiltration and drying time is prolonged on skin

Engineering Contradiction:
Improveskin safety and ink harmlessnessVSAvoidink infiltration and drying time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent modifies the surface parameters of the skin by applying a primer composition containing powder particles with specific size ranges (5-50 μm) and binder content (1-20 parts by weight per 100 parts powder). This changes the physical parameters of the skin surface to improve ink absorption rate and reduce drying time, while maintaining skin safety as the primer uses biocompatible materials.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If ink infiltration into the skin is delayed, then the ink remains on the surface, but smudging and color contamination occurs

Engineering Contradiction:
Improveink positioning accuracyVSAvoidink smudging and color contamination
Core Design Contradiction:
Manufacturing precisionVSObject-generated harmful factors

Solution Approach 1:

The patent applies a primer composition to the skin before printing the water-based ink. This preliminary action creates a prepared surface that immediately absorbs the ink upon contact, preventing the ink from spreading or smudging on the skin surface. The primer particles (5-50 μm) provide instant absorption capability that secures ink positioning accuracy from the moment of application.

Inventive Principle:
Principle #10Preliminary action

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 proposed method and kit significantly improve the printing performance and skin fixing ability of the ink, ensuring vibrant colors and preventing smudging, thereby achieving excellent print quality on the skin.
