Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing image forming apparatuses require users to manually search for and select new sheet sizes for processing conditions, which is inconvenient when the detected sheet size does not match the stored size, leading to user trouble in setting optimal processing conditions.

Innovation Solution

A sheet processing apparatus and method that includes a detection step to determine sheet size, a display step to show available sheet sizes for selection, and a change step to allow users to designate a new sheet size from the detected result, simplifying the process of setting processing conditions by displaying relevant sheet sizes based on detection results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the detection processing portion detects the sheet size automatically, then the measurement precision is improved, but the ease of operation deteriorates because users still need to manually search and select the correct sheet size from stored options

Engineering Contradiction:

Improvesheet size detection accuracyVSAvoidprocessing condition setting convenience

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system performs preliminary actions by detecting the sheet size automatically before the user needs to set processing conditions. The detection processing portion measures the sheet size in advance, and the setting processing portion prepares the corresponding processing conditions, so users only need to confirm rather than search and select manually.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system makes the sheet processing apparatus self-service by enabling automatic sheet size detection and automatic setting of processing conditions based on the detected size. The detection processing portion and setting processing portion work together to automatically configure parameters without requiring user intervention in the selection process.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If the setting screen displays all stored sheet sizes for selection, then the adaptability is improved, but the device complexity increases due to additional display and selection interface elements

Engineering Contradiction:

Improvesheet size selection flexibilityVSAvoidsetting screen complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The setting screen displays different information based on the local context of the detected sheet size. Instead of showing all possible sheet sizes uniformly, the system selectively displays only the detected size and relevant processing conditions, making the interface simpler while maintaining adaptability through conditional display logic.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If the system stores multiple sheet size options for selection, then the adaptability is improved, but the loss of time increases because users must search through stored options to find the correct size

Engineering Contradiction:

Improvesheet size option availabilityVSAvoidsheet size selection time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs the search and selection process in advance by automatically detecting the sheet size before the user needs to set processing conditions. The detection processing portion measures the sheet size in advance, eliminating the need for users to search through stored options and significantly reducing the time required.

Inventive Principle:

Principle #10Preliminary action

4Productivity

If the detection processing portion automatically detects sheet size, then the productivity is improved, but the reliability deteriorates when the detected size does not match the actual sheet size stored in the cassette

Engineering Contradiction:

Improveprocessing condition setting speedVSAvoidsheet size detection accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system implements feedback by displaying the detected sheet size on the setting screen for user confirmation. When the detected size does not match the actual sheet size, the user can provide corrective input, and the setting processing portion adjusts the processing conditions accordingly, ensuring reliable operation while maintaining high productivity.

Inventive Principle:

Principle #23Feedback

AI summary

A sheet processing apparatus includes a display processing portion, a setting processing portion, an acceptance processing portion, and a change processing portion. The display processing portion causes a setting screen including a detection result on a sheet size of a sheet stored in a sheet storing portion to be displayed. The setting processing portion sets a processing condition of the sheet based on information included in the setting screen. The acceptance processing portion causes some of sheet sizes used for setting the processing condition to be displayed according to a specific operation corresponding to the detection result on the sheet size of the sheet included in the setting screen, and accepts a designation operation for designating any of the displayed sheet sizes. The change processing portion changes, according to the designation operation, the sheet size included in the setting screen to a sheet size designated by the designation operation.
