Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If digital printing is used to enable variable data printing with personalized products, then product customization capability is improved, but data management complexity increases

Engineering Contradiction:
Improveproduct customization capabilityVSAvoiddata management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary data management system that acts as a mediator between the digital printing system and the workflow control system. This intermediary layer handles the complex tasks of storing, retrieving, and managing variable data for personalized products, thereby reducing the data management complexity burden on the printing system itself while maintaining high product customization capability

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements preliminary action by pre-processing and organizing variable data before the actual printing process. Data is prepared, validated, and structured in advance according to the personalized product requirements, which simplifies the real-time printing operations and reduces on-the-fly data management complexity

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If sequential digital printing is used to produce signatures and sheets, then production flexibility is improved, but processing time increases

Engineering Contradiction:
Improveproduction flexibilityVSAvoidprocessing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies continuity of useful action by implementing a continuous workflow where digital printing, folding, cutting, and stacking operations proceed without interruption. The printing system continuously produces signatures and sheets that are immediately processed by downstream equipment, eliminating idle time and maintaining constant productive action throughout the production line

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent implements dynamics by enabling the printing system to dynamically adjust printing parameters, sequences, and formats based on real-time production requirements. The workflow control system dynamically coordinates different processing stages, allowing the system to adapt flexibly to varying product specifications while maintaining efficient processing speeds

Inventive Principle:
Principle #15Dynamics

3Productivity

If inline processing is implemented for digitally printed signatures, then production efficiency is improved, but equipment complexity increases

Engineering Contradiction:
Improveproduction efficiencyVSAvoidequipment complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges multiple processing functions (printing, folding, cutting, stacking, and quality control) into a single integrated inline processing system. By combining these previously separate operations into one coordinated workflow, the system achieves high production efficiency while the complexity is managed through unified control rather than multiple independent systems

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements universality by designing processing equipment that can perform multiple functions within the inline workflow. For example, a single processing station can handle different operations depending on the product type, and the workflow control system can direct various substrates and printed materials through the same equipment序列, reducing the need for specialized equipment for each function

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

AI summary

The present invention relates to a method for producing a print job by sequential or quasi-sequential digital printing, wherein the signatures and/or individual sheets produced by digital printing form at least one stack, the components of which are transformed into at least one printed product by at least one further processing step, these printed products having an individual character, and are grouped into individual packages according to certain criteria. Production-related data or data sets control the sequence and design of the individual printed products with the same or different thickness and/or format and/or with the same or individual content.
