Solution Overview

Problem

Existing image forming apparatuses require users to manually change job setting values for each routine task, increasing user workload when multiple users execute jobs with different setting values.

Innovation Solution

An image forming apparatus that automatically stores and retrieves job setting values associated with slot numbers, allowing users to switch between types of job settings without manual reconfiguration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If job setting values are saved without being associated with a user, then user authentication requirements are reduced, but users must manually change setting values every time they switch between different routine tasks

Engineering Contradiction:
ImproveUser operation convenienceVSAvoidTime for manual setting changes
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically saving job setting values when users switch between different types (e.g., from copying to scanning). This eliminates the need for users to manually reconfigure settings when returning to a previously used type, thus resolving the contradiction between ease of operation and time loss.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides self-service functionality by automatically managing job setting values based on type transitions. The apparatus itself monitors type changes and restores appropriate settings without user intervention, making the system serve itself rather than requiring continuous manual configuration by the user.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If job setting values are saved for each user, then user-specific preferences are preserved, but users executing routine tasks must re-authenticate and cannot share settings efficiently

Engineering Contradiction:
ImproveUser-specific setting customizationVSAvoidSpeed of job execution
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system segments the setting management by dividing it into type-specific settings rather than user-specific or entirely generic settings. Each type (copying, scanning, faxing) has its own saved setting values, allowing efficient switching between routine tasks of the same type while maintaining adaptability for different users working on similar task types.

Inventive Principle:
Principle #1Segmentation

3Loss of information

If the system saves all changed setting values, then complete job configuration history is maintained, but storage resources are consumed and system complexity increases

Engineering Contradiction:
ImproveSetting value preservationVSAvoidSetting management system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system applies local quality by saving setting values specifically for each type (copying, scanning, faxing) rather than maintaining a universal setting repository. This localized approach preserves necessary information for each functional category while avoiding the complexity of managing all possible settings across all users and functions simultaneously.

Inventive Principle:
Principle #3Local quality

AI summary

An image forming apparatus executing a job relating to image processing includes a setting unit configured to set a UI screen corresponding to an application for executing the job so that the UI screen is in a state of a type selected by a user from a plurality of types, a management unit configured to, in a case where the user changes a setting value on the UI screen in the state of the set type to execute the job, store the changed setting value associated with information on the set type, and a control unit configured to, in a case where a currently set type is changed to another type based on selection by the user, display the UI screen in a state of the other type using a setting value associated with information on the other type out of setting values stored by the management unit.
