Solution Overview

Problem

Existing methods for producing functional labels are inefficient and costly, lacking a simple and reliable method to integrate multiple printing and die-cutting operations, which are essential for creating labels that can identify and protect against tampering.

Innovation Solution

A method combining hybrid printing and separate die-cutting operations, including conventional and digital printing, to create functional labels with integrated die-cuts, slits, and perforations, allowing for efficient production without changing paper types, and incorporating weakening zones for improved tear resistance and hanger elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate printing and die-cutting operations are performed to create functional labels, then the label functionality and identification reliability are improved, but the production complexity and cost increase

Engineering Contradiction:
Improveidentification reliabilityVSAvoidproduction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate printing operations (conventional printing and digital printing) and die-cutting operations into an integrated production process. The first printing device applies conventional printing, followed by die-cutting to create functional features, then a second digital printing device applies additional printing, and finally format die-cutting creates the label shape. This merging of operations into a coordinated sequence improves identification reliability through multiple printing layers and functional die-cuts while managing production complexity through systematic integration.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If conventional printing methods are used for functional labels, then production cost is reduced, but manufacturing flexibility and customization capability are limited

Engineering Contradiction:
Improveproduction costVSAvoidmanufacturing flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent segments the printing process into two distinct parts: conventional printing (first printing device) for cost-effective base labeling, and digital printing (second printing device) for flexible customization and variable data. This segmentation allows each printing method to be used where it provides the most value - conventional printing for standard elements and digital printing for customized elements - thereby achieving both cost efficiency and manufacturing flexibility.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If functional die-cuts are created in all label layers, then hanging functionality is improved, but the structural integrity and tear resistance of the label deteriorates

Engineering Contradiction:
Improvehanging functionalityVSAvoidtear resistance
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The patent applies local quality by creating functional die-cuts (such as hanging tabs or dispensing overlaps) in specific localized areas of the label rather than throughout the entire label structure. The format die-cut creates the overall label shape and maintains structural integrity, while functional die-cuts are strategically placed only where hanging or dispensing functionality is needed. This localized approach preserves tear resistance in critical areas while providing hanging functionality where required.

Inventive Principle:
Principle #3Local quality

AI summary

The invention relates to a method for producing a functional label (1), which method comprises: providing a starting material (108) having one or more label layers (10, 20), and carrying out a first printing process and thereby forming a print on the starting material (108) by means of a first printing device (101). The method also comprises carrying out a first punching process and thereby forming a functional punch (13, 16, 23, 26) in the starting material (108) by means of a first punching device (102). The method also comprises carrying out a second printing process which is separate from the first printing process and thereby forming a digital print (14) on the starting material (108) by means of a second printing device (103). The method further comprises carrying out a second punching process which is separate from the first punching process and thereby forming a format punch in the starting material (108) by means of a second punching device (104) and thereby forming the functional label (1).
