Solution Overview

Problem

Existing methods for producing temporary tattoos with metallic foil layers are slow, labor-intensive, and lack precision in image detail and color registration, especially when using hot foil stamping processes that require multiple passes through a letter press.

Innovation Solution

The method involves using offset or flexographic printing presses to produce temporary tattoos with a multi-layer structure, including a metal or metallic-based foil layer, applying ink and adhesive layers in a series of passes to achieve crisp, clear images with unlimited colors, and utilizing cold foil that allows for precise registration and larger sheet sizes, reducing labor and increasing production speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If hot foil stamping process is used, then metallic foil layers can be applied, but production speed is slow and labor-intensive

Engineering Contradiction:

Improveproduction speedVSAvoidlabor intensity

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The patent replaces the traditional hot foil stamping mechanical process with a printing press system that applies adhesive and foil in a streamlined manner, eliminating the need for heat and pressure application through mechanical stamping, thereby increasing production speed and reducing labor intensity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fundamental parameters of the foil application process by eliminating heat and pressure requirements, allowing the process to be integrated into continuous printing press operations rather than discrete stamping steps, which dramatically improves productivity

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If multiple passes through letter press are used, then foil layers can be applied, but image detail and color registration precision deteriorate

Engineering Contradiction:

Improvecolor registrationVSAvoidnumber of passes

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines the adhesive application and foil application steps into a single integrated process on the printing press, eliminating the need for multiple separate passes through the letter press, thereby improving color registration precision and reducing process complexity

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the foil application process into distinct adhesive application and foil application zones within the printing press system, allowing precise control and registration of each layer without requiring multiple passes through the entire press

Inventive Principle:

Principle #1Segmentation

3Manufacturing precision

If hot foil stamping is used, then foil can be applied, but image crispness and clarity are poor

Engineering Contradiction:

Improveimage crispnessVSAvoidproduction speed

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The patent replaces the hot foil stamping mechanical system with a printing press-based system that applies adhesive and foil with greater precision, producing crisper and clearer images while maintaining high production speed through continuous processing

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Productivity

If smaller sheet sizes are used, then hot foil stamping can be performed, but production volume is limited

Engineering Contradiction:

Improveproduction volumeVSAvoidprocess compatibility

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The patent adapts the foil application process to work with standard printing press sheet sizes, making the process compatible with existing printing press capabilities while enabling larger production volumes through the use of full-sized sheets rather than limited smaller formats

Inventive Principle:

Principle #6Universality (Multi-functionality)
