Solution Overview

Problem

Current methods for decorating outer packaging cannot simultaneously apply high-quality, visually appealing decorations and individualized machine-readable optical markings efficiently, often requiring separate processing steps and increasing production costs and reject rates.

Innovation Solution

A method that integrates the application of both optically variable decorative elements and individualized machine-readable optical markings onto a surface, such as packaging, using a transfer tape with pattern-shaped adhesive and deactivation layers, allowing for precise registration and simultaneous application in a single step, reducing production complexity and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate processing steps are used for applying decorative elements and machine-readable markings, then each can be applied with dedicated processes, but production complexity and costs increase

Engineering Contradiction:
Improvequality of decoration and marking applicationVSAvoidproduction process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the application of decorative elements and machine-readable optical markings into a single transfer step using one transfer tape. The transfer tape contains both the decorative layer with optically variable elements and a customizable layer with machine-readable markings, allowing both to be transferred simultaneously to the surface to be decorated, thereby reducing production complexity while maintaining quality

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transfer tape serves multiple functions: it acts as a carrier for decorative elements, a template for individualized markings, and a transfer medium for both decorative and functional layers. This multi-functional approach eliminates the need for separate processing equipment and steps for applying decorations and markings

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If separate processing steps are used for decorative elements and markings, then each can be optimized independently, but production time and reject rates increase

Engineering Contradiction:
Improvequality of decoration and markingVSAvoidproduction efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The transfer process continues uninterrupted by transferring both decorative and customizable layers in one continuous action. The embossing tool presses the transfer tape against the surface to be decorated, transferring both the decorative layer and the customizable layer with machine-readable markings simultaneously, eliminating idle time between operations and reducing reject rates

Inventive Principle:
Principle #20Continuity of useful action

3Adaptability or versatility

If machine-readable markings are applied separately, then they can be individually customized, but positioning precision relative to decorative elements becomes unpredictable

Engineering Contradiction:
Improveindividualization of markingsVSAvoidpositioning precision of markings
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The transfer tape features locally differentiated properties: the decorative layer provides visual appeal while the customizable layer contains individualized machine-readable markings. The pattern-shaped adhesive layer is applied only in specific areas corresponding to the customizable layer, ensuring precise positioning of markings relative to decorative elements while allowing individual customization of each marking

Inventive Principle:
Principle #3Local quality

AI summary

The invention relates to a method and a transfer tape for decorating surfaces, in particular for decorating outer packaging. A transfer tape is provided comprising a carrier film (11) in the form of a strip, a decorative layer (13) and a release layer (12) arranged between the decorative layer (13) and the carrier film. The decorative layer (13) has a large number of optically variable decorative elements of the same type, which are arranged in first surface areas which are separate from one another and spaced apart from one another in the longitudinal direction of the transfer belt. The decorative layer (13) has second surface areas which are separate from one another and are spaced apart from one another in the longitudinal direction of the transfer belt and in which the decorative layer (13) has one or more customizable layers for providing different machine-readable optical markings in each case. A first surface area or a sub-area of ​​a first surface area and a second surface area or a sub-area of ​​a second surface area of ​​the decorative layer (13) are transferred onto a surface to be decorated. The one or more individualizable layers of the respective second surface area are individualized before or during the transfer, so that in addition to one of the optically variable decorative elements, an individualized machine-readable optical marking is transferred from the transfer tape onto the surface to be decorated.
