Solution Overview

Problem

Conventional devices for producing value and security documents are limited in their usability due to fixed configurations of functional modules, which restrict their ability to produce different types of documents and require additional devices for processes like ink drying or UV curing, leading to increased installation space and maintenance challenges.

Innovation Solution

A device with a modular design that allows interchangeable functional modules to be arranged in various positions and orientations, enabling the production of diverse types of value and security documents by combining different modules, such as printing, heating, and surface treatment modules, while minimizing installation space and facilitating easy maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional devices use a fixed configuration of functional modules, then the device structure is simple and stable, but the usability and adaptability for producing different types of documents is limited

Engineering Contradiction:
Improveusability for producing different types of documentsVSAvoiddevice structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into separate, interchangeable functional modules (printing module, heating module, UV module, etc.) that can be independently selected and combined. Each module performs a specific function and can be attached or detached from the support structure, allowing the device to be configured for different document production needs without requiring a completely different device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support structure is designed with universal receiving elements that can accommodate multiple types of functional modules. The same support structure and receiving elements can hold different modules (printing, heating, UV, etc.), making the base device universal and adaptable to various production requirements by simply changing the modules.

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

2Adaptability or versatility

If additional auxiliary equipment is permanently installed for drying or UV curing, then the functionality is complete, but the installation space requirement increases

Engineering Contradiction:
Improvefunctionality for drying and UV curingVSAvoidinstallation space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

Multiple functions (printing, heating for drying, UV curing) are merged into a single integrated device by combining different functional modules on one support structure. This eliminates the need for separate auxiliary equipment and reduces the total installation space while maintaining complete functionality for various document production processes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device configuration is made dynamic and adjustable rather than fixed. Modules can be added, removed, or repositioned based on the specific production needs, allowing the installation space to be optimized for each application while maintaining all necessary functionalities when required.

Inventive Principle:
Principle #15Dynamics

3Reliability

If multiple separate devices are arranged one behind another for different functions, then each device has dedicated functionality, but the installation space and maintenance complexity increase

Engineering Contradiction:
Improvededicated functionality for each process stepVSAvoidinstallation space
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

Multiple separate functional devices (printing, heating, UV curing) are merged into a single integrated device with a common support structure and control system. Each function maintains its dedicated module for reliability, but they are combined in one physical unit, dramatically reducing installation space and simplifying maintenance compared to separate devices arranged in sequence.

Inventive Principle:
Principle #5Merging (Combining)

4Use of energy by moving object

If the reservoir is arranged above the printhead in the direction of gravity, then the printing fluid can be supplied by gravity, but the printing fluid may leak from the nozzles in case of power failure

Engineering Contradiction:
Improveenergy efficiency for printing fluid supplyVSAvoidprinting fluid leakage
Core Design Contradiction:
Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

A check valve is installed in the fluid supply line between the reservoir and printhead to prevent backflow of printing fluid. This preliminary protective measure ensures that even if the reservoir is positioned above the printhead for gravity-fed supply, the printing fluid cannot leak from the nozzles during power failures or unexpected shutdowns, as the check valve blocks reverse flow.

Inventive Principle:
Principle #9Preliminary anti-action
