Solution Overview

Problem

Existing sheet processing systems face difficulties in accurately setting processing positions for print images due to reliance on sheet edges, making it challenging to generate processing jobs effectively.

Innovation Solution

A processing job generation apparatus that displays print images and processing marks simultaneously, allowing for intuitive setting of processing positions based on the print image and sheet dimensions, with automatic alignment features to enhance accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If processing position is designated with reference to sheet edges, then sheet processing can be performed, but it becomes difficult to set processing position for print images and generate processing jobs

Engineering Contradiction:

Improveprocessing position settingVSAvoidprocessing position accuracy

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The patent introduces a processing mark as an intermediary element between the sheet edge and the print image. The processing mark is displayed on the sheet along with the print image, serving as a visual mediator that helps operators accurately determine processing positions relative to the print image rather than relying solely on sheet edges. This intermediary marker enables both ease of operation and processing position accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If processing position is set based on sheet edges, then sheet handling is simplified, but the relationship between print image and processing position becomes unclear

Engineering Contradiction:

Improveprocessing job generationVSAvoidimage-processing position relationship

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The patent merges the processing mark with the print image display on the sheet. By combining these two elements visually, the system maintains clear information about the relationship between the print image and processing position while simplifying the processing job generation process. The merged display allows operators to simultaneously view both the print image and processing mark, eliminating information loss.

Inventive Principle:

Principle #5Merging (Combining)

3Measurement precision

If processing marks are added to sheets, then processing position can be accurately determined, but sheet structure becomes more complex

Engineering Contradiction:

Improveprocessing position determinationVSAvoidsheet structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The processing mark is created as a visual copy or representation on the sheet, rather than a physical structural modification. This copying approach allows accurate processing position determination through visual display while avoiding complex physical changes to the sheet structure. The mark can be displayed using standard printing or imaging technologies without altering the sheet's fundamental structure.

Inventive Principle:

Principle #26Copying

AI summary

A processing job generation apparatus (10) includes an acquisition unit (101) that acquires first information on a print image, and a processing position setting unit (102) that causes a print image and a processing mark indicating a processing position of processing to be performed on the sheet to be simultaneously displayed on the display device (14), and sets a processing position on basis of the print image and the processing mark displayed on the display device (14).
