Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Multifunction devices lack an effective method to dynamically switch between customized and default screens during printing or processing, especially when errors occur, affecting user experience and operational efficiency.

Innovation Solution

A printing method and system that allows administrators to customize printing screens, displaying customized content during printing, and automatically switching to a default screen upon error resolution, ensuring seamless operation and user engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a customized printing screen is displayed during printing, then user experience is improved by providing useful waiting time information, but when an error occurs and printing is resumed, the customized screen may display incorrect or misleading information

Engineering Contradiction:

Improveaccuracy of screen informationVSAvoiduser experience during printing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The printing screen dynamically switches between customized and default display modes based on the printing state. When printing is resumed after an error, the system automatically transitions from the customized screen to the default screen to ensure information accuracy, then can switch back to customized mode after completion, making the screen adaptable to different operational states

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the display parameter (customized vs default screen) based on the printing state. The display mode is adjusted according to whether printing is in normal state or resume state, ensuring that the screen information matches the actual printing status

Inventive Principle:

Principle #35Parameter changes

2Loss of information

If the customized printing screen is always displayed during printing, then user engagement is enhanced, but the system cannot provide accurate status information after error recovery

Engineering Contradiction:

Improveaccuracy of printing status informationVSAvoiduser waiting time utilization

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The printing process is segmented into different states (normal printing and resume after error), and the display mode is segmented accordingly (customized screen for normal state, default screen for resume state). This segmentation ensures that each state has the appropriate display information

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The printing state (error occurrence and recovery) acts as an intermediary that triggers the switch between customized and default screens. The state information mediates between the customized display requirements and the need for accurate status information

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A printing method includes a customizing step of receiving a customization instruction of an administrator and customizing a printing screen, a printing step of performing printing in response to reception of a printing start instruction, and a displaying step of displaying the customized printing screen during the printing step, in which when an error occurs in the printing step and then the error is resolved and printing is resumed, a display is performed by switching to an uncustomized printing screen immediately after resuming.
