Solution Overview

Problem

Current vacuum flatbed table inkjet printing devices are inefficient as they require multiple machines to handle different substrates, leading to increased calibration and maintenance time, and reduced productivity due to the need for separate devices for each substrate type.

Innovation Solution

A removable stationary flat substrate support device is coupled to the vacuum flatbed table, allowing for easy switching between substrates, enabling the same inkjet printing device to handle various substrates without the need for multiple machines, by using ball transfer units, idler rollers, and treatment means for immobilizing ink, regulating humidity, and applying controlled temperature.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple vacuum flatbed table inkjet printing devices are used to handle different substrate types, then each substrate type can be processed with optimized support, but the overall productivity decreases due to increased calibration and maintenance time across multiple devices

Engineering Contradiction:
Improvesubstrate handling capabilityVSAvoidprinting productivity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements a universal support device that can accommodate multiple substrate types (glass, metal, plastic, wood, paper) through a single inkjet printing device. The support device includes interchangeable support surfaces and adjustable positioning mechanisms that adapt to different substrate characteristics, eliminating the need for multiple dedicated printing devices while maintaining optimized support for each substrate type

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

Solution Approach 2:

The support device is divided into modular components including removable support surfaces, adjustable positioning elements, and interchangeable fixtures. This segmentation allows rapid reconfiguration between different substrate types without requiring complete device replacement or extensive calibration, thereby maintaining productivity while achieving versatility

Inventive Principle:
Principle #1Segmentation

2Productivity

If a single inkjet printing device handles all substrate types, then productivity increases by reducing calibration and maintenance time, but the adaptability to handle specialized substrates (like glass or metal) decreases without proper support mechanisms

Engineering Contradiction:
Improveprinting productivityVSAvoidsubstrate handling capability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The support device incorporates dynamic, adjustable components that can be reconfigured for different substrate types. The support surfaces can be adjusted in position and orientation, and specialized fixtures can be attached or removed based on the specific substrate requirements, allowing a single device to maintain high productivity while adapting to diverse substrate handling needs

Inventive Principle:
Principle #15Dynamics

3Area of stationary object

If a large vacuum flatbed table is used to support maximum printing size, then the ability to print on large or multiple substrates improves, but the complexity of the device increases and requires more extensive calibration and service time

Engineering Contradiction:
Improveprinting areaVSAvoiddevice complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The large printing area is achieved through modular support surfaces that can be arranged and configured as needed. The support device itself is segmented into manageable components that can be independently serviced and calibrated, reducing the overall complexity management while maintaining the capability to support large or multiple substrates

Inventive Principle:
Principle #1Segmentation
