Solution Overview

Problem

Existing card customization systems require complex management and storage of pre-printed labels for different card issuers, leading to increased space and cost requirements, while maintaining high productivity and quality.

Innovation Solution

A method where labels are applied to cards before printing, allowing direct in-line printing of customized information on the label after application, reducing the need for pre-printed label storage and management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If labels are pre-printed and stored for different card issuers, then customization quality is maintained, but space requirements and system complexity increase

Engineering Contradiction:
Improveprinting qualityVSAvoidstorage space
Core Design Contradiction:
Manufacturing precisionVSVolume of stationary object

Solution Approach 1:

The label is prepared and applied to the card in advance, but the actual customization printing is performed later in-line during the card customization process. This preliminary application of the blank label eliminates the need to store multiple pre-printed label variants, while still enabling high-quality customized printing when needed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of the conventional approach of printing labels in advance and storing them, the invention inverts the sequence by first applying blank labels to cards and then performing the customization printing in-line. This reversal eliminates storage requirements while maintaining printing quality.

Inventive Principle:
Principle #13The other way round (Inversion)

2Manufacturing precision

If pre-printed labels are managed and stored, then printing quality is ensured, but system complexity and costs increase

Engineering Contradiction:
Improveprinting qualityVSAvoidlabel management system
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The label is prepared and applied to the card in advance, but the actual customization printing is performed later in-line during the card customization process. This preliminary application of the blank label eliminates the need to store multiple pre-printed label variants, while still enabling high-quality customized printing when needed.

Inventive Principle:
Principle #13The other way round (Inversion)

3Volume of stationary object

If labels are applied before printing, then storage space is reduced, but printing process complexity increases

Engineering Contradiction:
Improvestorage spaceVSAvoidprinting process
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The invention merges the label application process with the card customization printing process into a single integrated in-line operation. The label is applied to the card and then immediately printed upon during the same continuous process flow, eliminating the need for separate pre-printing and storage operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The printing system is designed to handle both card printing and label printing through a single multi-functional in-line printing unit. This universal printing capability allows the system to print on both the card surface and the applied label without requiring separate dedicated printing lines.

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

4Manufacturing precision

If pre-printed labels are used, then printing quality is maintained, but productivity and flexibility decrease

Engineering Contradiction:
Improveprinting qualityVSAvoidcards per hour
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The in-line printing process operates continuously as cards move through the customization line, with labels being applied and printed upon without interruption or batch processing. This continuous operation eliminates the downtime associated with changing pre-printed label rolls and maximizes productivity.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system dynamically adjusts printing parameters and label application timing based on real-time card customization requirements. This dynamic adaptation allows the system to maintain high printing quality while accommodating varying production demands and different card types without reducing overall productivity.

Inventive Principle:
Principle #15Dynamics
