Solution Overview

Problem

Existing flatbed printers often have fixed or limited vacuum zones, making it difficult for users to ensure that printed images fit within the vacuum area, leading to potential poor image quality and inefficient media usage.

Innovation Solution

A method that uses a graphical representation on a job editor to visualize the vacuum zone, allowing users to edit print jobs by scaling, rotating, or selecting the appropriate vacuum zone configuration to ensure the image fits within the vacuum area, with options for manual entry or transmission of vacuum zone data to the processor for precise alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the vacuum zone has a fixed size and shape, then the device structure is simple, but the adaptability to different media sizes and image dimensions is poor

Engineering Contradiction:
Improveadaptability to different media sizesVSAvoidvacuum zone configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The vacuum zone is configured to be dynamically adjustable rather than fixed. The system allows the vacuum zone size and shape to be changed based on the media size and image dimensions, enabling adaptation to different printing requirements without requiring multiple fixed vacuum zones.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameters of the vacuum zone (size, shape, position) according to the specific printing job requirements. By adjusting these parameters, the same vacuum zone can accommodate different media sizes and image dimensions, improving versatility without increasing device complexity.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the user cannot visually check the vacuum zone coverage, then the operation is simpler, but the reliability of image positioning is poor

Engineering Contradiction:
Improveimage positioning accuracyVSAvoidjob editor functionality
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system creates a visual copy or representation of the vacuum zone on the job editor display. This graphical representation allows users to see exactly how the vacuum zone will cover the media and image, enabling them to verify positioning accuracy before actual printing without adding physical complexity to the printer itself.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The job editor acts as an intermediary between the user and the vacuum zone. It provides a visual interface that mediates the interaction by displaying the vacuum zone coverage, allowing users to make informed decisions about image positioning and scaling without directly interacting with the physical vacuum zone mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the image is scaled or rotated to fit the vacuum zone, then the media fixation reliability is improved, but the image quality may be compromised

Engineering Contradiction:
Improvemedia fixation reliabilityVSAvoidimage quality
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The system performs preliminary scaling and rotation adjustments to the image before printing, based on the vacuum zone dimensions. By pre-calculating and applying these transformations, the image is optimally positioned and sized to fit within the vacuum zone boundaries, ensuring both reliable media fixation and maintaining acceptable image quality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system adjusts image parameters (scale, rotation angle, position) to optimize the fit within the vacuum zone. These parameter changes are calculated to maintain image quality while ensuring the entire image area falls within the vacuum zone coverage, thus achieving both reliable fixation and acceptable quality.

Inventive Principle:
Principle #35Parameter changes
