Solution Overview

Problem

Existing embossing and debossing processes face challenges in accurately aligning dies, which can lead to misalignment and damage during the securing process, and require separate operations for cutting and embossing/debossing, involving expensive and environmentally burdensome methods.

Innovation Solution

The use of magnetic or magnetically permeable backings for both male and female dies allows for automatic alignment through weak magnetic attraction, ensuring accurate positioning and secure fastening without damaging the dies, and enables simultaneous cutting and embossing/debossing using a single pass with a magnetic base plate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the counter is positioned by hand over the female die and fastened using double sided adhesive tape, then the counter can be secured to the platen or cylinder, but the counter may move out of its correct position or alignment during the fastening process

Engineering Contradiction:

Improvealignment accuracyVSAvoidfastening process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical adhesive tape fastening system with a magnetic field-based fastening system. Magnets embedded in the platen or cylinder attract the magnetically permeable counter, providing secure attachment without requiring manual positioning and fastening with adhesive tape. This eliminates the risk of misalignment during the fastening process while maintaining ease of operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a magnetic field as an intermediary between the platen/cylinder and the counter. The magnetic field acts as a mediator that automatically maintains proper alignment and secures the counter during the fastening process, eliminating the need for manual positioning and adhesive tape application.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the counter is fastened using double sided adhesive tape, then the counter can be secured to the platen or cylinder, but the male counter may be damaged in the securing process

Engineering Contradiction:

Improvesecuring effectivenessVSAvoiddie damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical adhesive tape system with a magnetic field-based fastening system. The magnetic attraction provides secure attachment without the need for adhesive tape application and removal, eliminating the risk of die damage associated with tape fastening while maintaining effective securing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic fastening system is self-adjusting and self-securing. The magnetic field automatically maintains proper alignment and secures the counter without requiring manual intervention for positioning and fastening, reducing the risk of damage during the securing process.

Inventive Principle:

Principle #25Self-service

3Ease of manufacture

If separate operations are used for cutting and embossing/debossing, then each operation can be performed with dedicated dies, but the process requires 2×1000 or 2000 operations and involves expensive environmentally burdensome methods

Engineering Contradiction:

Improvededicated die functionalityVSAvoidoperations per batch

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent merges the cutting die and embossing/debossing counter into a single integrated die assembly. The magnetically permeable counter with integrated cutting edges allows both cutting and embossing/debossing operations to be performed simultaneously in one pass, eliminating the need for separate operations and reducing total operations from 2×1000 or 2000 to a single operation per batch.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated die assembly serves multiple functions: it performs both cutting and embossing/debossing operations simultaneously. The magnetically permeable material allows the counter to be securely attached to the platen or cylinder while the integrated cutting edges enable cutting functionality, creating a universal tool that eliminates the need for separate dedicated dies.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A set of dies for embossing or debossing is disclosed. The set has a female die (4, 80) and a male die (7, 67) each which has a steel backing plate (5, 47, 75). One of the dies is strongly magnetically attracted to a base plate (1, 68) which results in a weak magnetic attraction between the two dies (4, 7 or 67, 80). The weak magnetic attraction enables the set of dies to be substantially automatically self-aligning. Furthermore, such a set of dies can be used with a cutting and creasing die (50) to permit embossing or debossing simultaneously with cutting and/or folding during the same run.
