Solution Overview

Problem

Inspection settings for non-standard sized sheets, such as long-sized or free-size sheets, are challenging due to inappropriate display of reference images on inspection setting screens, making it difficult for users to set inspection areas accurately.

Innovation Solution

The display control unit adjusts the arrangement of the reference image and operation object areas on the setting screen based on the size of the reference image, ensuring appropriate viewing and setting for different sheet sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the reference image is displayed on the inspection setting screen using a fixed arrangement, then the layout is simple and easy to implement, but the reference image may be displayed in a small size on the screen when inspecting long-sized sheets, making it difficult for users to appropriately set the inspection content

Engineering Contradiction:
Improveease of setting inspection contentVSAvoidcomplexity of display arrangement control
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The display control unit dynamically changes the arrangement of the first display area (reference image) and second display area (operation objects) based on the sheet size. For long-sized sheets, the reference image is arranged on the left side with operation objects on the right side, while for standard sheets, the arrangement is reversed. This dynamic adaptation ensures the reference image is always displayed at an appropriate size and position, making it easier for users to set inspection content accurately.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the inspection setting screen is designed for standard sheet sizes, then the display layout is optimized for common sheets, but it becomes inappropriate and difficult to use when inspecting long-sized or free-size sheets

Engineering Contradiction:
Improveadaptability to different sheet sizesVSAvoidease of viewing reference image
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The display control unit applies different display arrangements based on the specific sheet size category. For long-sized sheets, the reference image is positioned on the left side of the screen, while for standard sheets, it is positioned on the right side. This localized optimization ensures that regardless of the sheet size being inspected, the reference image is always displayed in the most appropriate position and size, enhancing user ease of operation for viewing and setting inspection content.

Inventive Principle:
Principle #3Local quality

AI summary

An inspection apparatus includes an inspection unit configured to perform inspection on an inspection image obtained by reading a sheet on which an image is formed, based on a reference image and the inspection image. The inspection apparatus further includes a display unit, and a display control unit configured to display, on the display unit, a setting screen including a first display area that displays the reference image and a second display area that displays an operation object for accepting an inspection setting for the inspection. The display control unit determines an arrangement of the first display area and the second display area in the setting screen in accordance with a size of the reference image.
