Solution Overview

Problem

The existing methods for transferring foil films with structural color onto substrates require multiple foil films at different angles, increasing transfer costs due to the need for multiple types of foil films.

Innovation Solution

A foil transfer device and method that uses a controller and foil applicator to transfer a single foil film onto a substrate at different angles for various areas, allowing the same foil film to be used for multiple areas with distinct angles, thereby reducing the need for multiple foil films.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple kinds of foil films with different angles are prepared to achieve diverse color expressions in different areas, then the diversity of visual expressions is improved, but the transfer costs increase due to the need for multiple foil films

Engineering Contradiction:

Improvediversity of visual expressionsVSAvoidtransfer costs

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single foil film is used to transfer to multiple different areas on the substrate, with the foil film being repositioned at different angles for each area. This makes the single foil film serve multiple functions that would traditionally require multiple different foil films, thereby reducing costs while maintaining visual diversity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The angle parameter of the foil film relative to the substrate is changed between transfers to different areas. By varying this angular parameter, different visual effects are achieved from a single foil film, eliminating the need to prepare multiple foil films with different fixed angles.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If multiple kinds of foil films with different angles are prepared for different areas, then the visual diversity across areas is improved, but the preparation and transfer process complexity increases

Engineering Contradiction:

Improvevisual diversity across areasVSAvoidpreparation and transfer process

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The same foil film is used universally for multiple transfer operations across different areas, eliminating the need to prepare multiple different foil films. The foil film is repositioned and reoriented between transfers, making a single component serve multiple purposes and simplifying the preparation process.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The foil film is made dynamically repositionable and reorientable between transfer operations. Instead of using static, pre-configured foil films for each area, the system allows dynamic adjustment of the foil film's position and angle, simplifying the overall manufacturing process.

Inventive Principle:

Principle #15Dynamics

AI summary

A foil transfer device may include a foil applicator to transfer a foil film onto a substrate, and a controller to transfer, using the foil applicator, foil from one foil film onto a first area of the substrate, the foil film having been placed at a first angle relative to the substrate, and transfer, using the foil applicator, foil from the foil film onto a second area of the substrate, the foil film having been placed at a second angle relative to the substrate, the second angle being different from the first angle, the second area being different from the first area.
