Solution Overview

Problem

Users of information processing apparatuses, such as image forming devices, face frustration and inconvenience due to delays caused by the need to wait during job cancellation processes, which prevent them from immediately re-executing jobs.

Innovation Solution

An information processing apparatus with a drive unit and display unit that allows users to cancel and re-execute jobs while displaying redo instructions, enabling operations during cancellation processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the job cancellation process stops drivers completely, then the cancellation is reliable, but the user must wait longer and cannot perform redo operations

Engineering Contradiction:
Improvecancellation reliabilityVSAvoiduser wait time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system displays information about the redo operation before the actual redo execution, allowing users to understand the process status and prepare for the next steps. This preliminary information display reduces user anxiety and perceived wait time while maintaining reliable cancellation processing in the background

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the driver stops completely during cancellation, then the cancellation is thorough, but the user cannot initiate redo operations immediately

Engineering Contradiction:
Improvecancellation thoroughnessVSAvoiduser operation flexibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts the operational state during cancellation by allowing redo operations to be initiated and displayed while maintaining driver stopping in the background. The user interface becomes more flexible to allow redo commands, while the driver stopping process continues to execute thoroughly without blocking user interaction

Inventive Principle:
Principle #15Dynamics

3Reliability

If the cancellation process waits for driver stop completion, then the cancellation is complete, but the user experience deteriorates due to inability to take action

Engineering Contradiction:
Improvecancellation completionVSAvoiduser action capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cancellation process is segmented into background driver stopping operations and foreground user interaction operations. The driver stopping continues in the background while the user interface independently handles redo operation displays and user inputs, allowing both cancellation completion and user action capability to coexist without blocking each other

Inventive Principle:
Principle #1Segmentation

AI summary

According to the present disclosure, an information processing apparatus (100) includes a drive unit (101) and a display unit (211). In the information processing apparatus, based on an instruction to retry a job that is being executed by the drive unit, processing of the drive unit in accordance with the job is cancelled, and information about the retrying of the job is displayed by the display unit. Based on an instruction to start the retrying of the job, the job is retried.
