Solution Overview

Problem

Users face challenges in confirming appropriate print settings when printing images in multiple layers, leading to wasted printouts due to incompatibility between print jobs and settings.

Innovation Solution

An image processing device with a controller that determines compatibility between print jobs containing multiple image layers and print settings, displaying error reports when they are not compatible, thereby preventing wasteful printouts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If users print images in multiple layers without verifying print settings compatibility, then printing operation is simple and fast, but print settings compatibility cannot be confirmed leading to wasted printouts

Engineering Contradiction:

Improveprinting speedVSAvoidprint settings compatibility

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs compatibility verification between print settings and multi-layer image data before the actual printing operation. The controller determines whether print settings are appropriate for the print job containing multiple image layers, and displays error reports if incompatibility is detected, preventing wasteful printouts.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to users by displaying error reports when print settings are incompatible with multi-layer print jobs. This feedback mechanism allows users to adjust their print settings before executing the print job, ensuring compatibility and avoiding wasted printing operations.

Inventive Principle:

Principle #23Feedback

2Reliability

If the system verifies compatibility between print jobs and print settings, then print settings compatibility is improved, but additional processing time and complexity are introduced

Engineering Contradiction:

Improveprint settings compatibilityVSAvoidsystem processing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs self-verification of print settings compatibility automatically without requiring user intervention. The controller autonomously determines whether print settings are appropriate for the print job and generates error reports if incompatibility is detected, reducing the burden on users while maintaining simplicity.

Inventive Principle:

Principle #25Self-service

3Loss of information

If error reports are displayed for incompatible print settings, then information about compatibility issues is provided, but user interface complexity increases

Engineering Contradiction:

Improvecompatibility informationVSAvoiduser interface complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system extracts and displays only the essential compatibility information in error reports when print settings are incompatible with multi-layer print jobs. By focusing on displaying only the necessary error information rather than all possible parameters, the interface remains simple while still providing critical feedback to users.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

Problems may be caused by incompatibility between a print job and print settings. An image processing device controls displaying content by a display, and has a controller configured to determine whether or not a print job containing multiple image layers is compatible with a print setting, and displays an error report on the display when the print job and print setting are not compatible. The controller displays a first input field to receive a number of image layers as part of the print setting, and displays the error report when the number of image layers set according to an operation on the first input field is not compatible with the number of image layers contained in the print job.
