Controller Timing Setting History Storage for Job Completion

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional image processing apparatuses fail to accurately store setting histories, leading to incomplete or inaccurate reproduction of jobs, especially when jobs are interrupted or incomplete, as they do not consider the type of job and settings during storage.

Innovation Solution

An image processing apparatus with a controller that determines the storage timing of setting histories based on the type of job and settings, ensuring that the history accurately reflects the final state of job execution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the setting history is stored with the pressing of a start button being a trigger, then the storage operation is simple and fast, but the setting history may be stored at a state of being in the middle of execution, leading to inaccurate job reproduction

Engineering Contradiction:

Improvestorage speedVSAvoidaccuracy of setting history

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system performs preliminary judgment about job completion status before storing the setting history. The controller determines whether the job has been completed based on completion determination means, and only stores the setting history when completion is confirmed, preventing storage of incomplete job states.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If all functions of the executed job are stored irrespective of execution result, then the storage operation is simple and comprehensive, but failed jobs are also stored, leading to repeated failures

Engineering Contradiction:

Improvestorage operation simplicityVSAvoidjob execution reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system introduces feedback by determining the completion status of the job before storing the setting history. The completion determination means provides feedback information about whether the job was successfully completed, and this feedback controls whether the setting history should be stored, preventing storage of failed job configurations.

Inventive Principle:

Principle #23Feedback

3Productivity

If the setting history is stored without considering job type and settings, then the storage operation is simple and fast, but the setting history does not accurately reflect the final state of job execution

Engineering Contradiction:

Improvestorage efficiencyVSAvoidaccuracy of job state information

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The system performs preliminary determination of job completion status before storing the setting history. The controller uses completion determination means to assess whether the job has reached its final state, ensuring that only accurate job state information is stored while maintaining storage efficiency.

Inventive Principle:

Principle #10Preliminary action

AI summary

An image processing apparatus including: a job executor which executes a job regarding image processing; a storage in which a setting history related to execution of the job is stored when the job is executed; and a controller which controls a storage timing to store the setting history, in which the controller decides on the storage timing on the basis of an execution condition for the job, thereby storing the setting history.
