Solution Overview

Problem

Traditional printing apparatuses require complex and time-consuming interventions by specialized personnel to change ink colors or materials, leading to long downtimes and limited user customization options due to the fixed positioning of ink tanks and pumping devices.

Innovation Solution

A modular printing unit with a tank, print head, and feed members connected via flexible tubes and rapid attachment means, allowing for easy replacement and customization of print materials without altering the overall structure, enabling non-specialized personnel to perform quick color and finishing personalizations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If ink tanks and pumping devices are fixed in position below the support plane, then structural stability is maintained, but customization of ink colors and materials requires complex interventions and long downtimes

Engineering Contradiction:
Improvecustomization of ink colors and materialsVSAvoiddowntime for replacement
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The printing apparatus is divided into modular printing units, each comprising a print head, tank, and feed members as an integrated assembly. This segmentation allows individual printing units to be replaced without affecting the entire system, enabling quick customization of ink colors and materials by simply swapping modules rather than performing complex interventions on fixed components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The printing units are designed as universal modules that can be selectively installed and removed from the slider. Each module contains all necessary components (print head, tank, feed members) to function independently, allowing the system to adapt to different printing needs by replacing entire units rather than reconfiguring individual components.

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

2Ease of operation

If print heads, pumping devices and recirculating devices are integrated on the slider, then printing functionality is optimized, but replacement and personalization require drastic structural interventions

Engineering Contradiction:
Improveease of personalizationVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The printing system is segmented into self-contained printing units that include print heads, tanks, and feed members. This modular architecture simplifies personalization operations because users only need to replace entire units rather than disassembling and reconfiguring complex integrated systems, thereby reducing both operational complexity and structural intervention requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular printing units are designed to be easily replaceable by non-specialized personnel through simple attachment and detachment operations. The self-contained nature of each unit allows users to perform maintenance and personalization tasks independently without requiring qualified personnel or complex structural modifications.

Inventive Principle:
Principle #25Self-service

3Reliability

If flexible tubes are used to feed ink from fixed tanks to moving print heads, then connectivity is maintained, but the tubes can get damaged during slider movement

Engineering Contradiction:
Improveconnection reliabilityVSAvoiddamage to flexible tubes
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system eliminates flexible tubes by segmenting the ink delivery function into self-contained printing units. Each unit integrates its tank and feed members with the print head, creating a closed system that moves as one rigid assembly. This eliminates the harmful flexible tubes entirely while maintaining reliable ink connectivity through fixed internal passages within each modular unit.

Inventive Principle:
Principle #1Segmentation
