Solution Overview

Problem

Tattoo transfer paper experiences wrinkles and pattern distortion during printing due to tension caused by independent printing processes, affecting user experience when transferring patterns onto the skin.

Innovation Solution

A thermal transfer printing method that involves acquiring pattern data and side line data, and controlling a print head to print according to the side line data and pattern data, ensuring balanced forces on both sides of the tattoo transfer paper, thereby preventing wrinkles and ensuring clear pattern development.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If tattoo transfer paper is printed independently without continuous feeding, then each tattoo transfer paper can be processed separately, but tension during printing causes wrinkles and pattern distortion

Engineering Contradiction:

Improveindependent printing processVSAvoidpattern distortion

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent applies counterweight principle by introducing side line data that generates opposite forces to balance the tension during printing. The side lines are positioned symmetrically on both sides of the pattern, creating counteracting forces that prevent the paper from deforming under tension, thus eliminating wrinkles and pattern distortion while maintaining independent printing capability.

Inventive Principle:

Principle #8Anti-weight (Counterweight)

2Reliability

If heating is applied to transfer dye, then pattern is transferred to base paper layer, but uneven stress causes wrinkles on the paper

Engineering Contradiction:

Improvepattern transferVSAvoidwrinkles on paper

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent uses asymmetry principle in reverse by creating symmetrical heating zones through side lines on both sides of the pattern. This symmetrical arrangement ensures uniform stress distribution across the paper during heating, preventing localized deformation and wrinkles while maintaining effective dye transfer to the base paper layer.

Inventive Principle:

Principle #4Asymmetry

3Productivity

If tension is applied during printing to feed paper, then printing process can be completed, but the pattern becomes deformed and distorted

Engineering Contradiction:

Improveprinting process completionVSAvoidpattern deformation

Core Design Contradiction:

ProductivityVSShape

Solution Approach 1:

The patent applies preliminary action by pre-calculating and positioning side line data before the actual printing process. The side lines are strategically placed to create balancing forces that counteract the tension-induced deformation, ensuring the pattern maintains its correct shape throughout the printing process while allowing continuous paper feeding.

Inventive Principle:

Principle #10Preliminary action
