Solution Overview

Problem

Existing image forming systems lack the ability to display switching information for paper feeding trays, making it difficult for users to manage paper refills and adjust settings before performing large jobs, leading to potential paper shortages and inefficient operation.

Innovation Solution

An image forming apparatus that displays switching information, including which tray to use, estimated paper remaining amount, and timing of switching, on a user interface, allowing users to adjust settings and prioritize tray usage before starting a job.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automatic switching between paper feeding trays is implemented, then the image forming apparatus can perform large amount jobs using multiple trays, but the user cannot know the switching timing and target tray information

Engineering Contradiction:
Improveability to perform large amount jobsVSAvoidswitching information
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The control section displays switching information on the display unit, providing feedback to the user about which tray will be switched and when the switching will occur during large amount jobs. This allows users to monitor and manage paper refilling proactively.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system calculates and displays switching information in advance before the actual switching occurs, allowing users to prepare paper refilling beforehand rather than reacting when paper runs out.

Inventive Principle:
Principle #10Preliminary action

2Extent of automation

If switching information is not displayed, then the apparatus operates automatically, but users cannot manage paper refilling and tray adjustments effectively

Engineering Contradiction:
Improveautomatic tray switchingVSAvoiduser management capability
Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The display unit provides real-time feedback about tray switching operations, showing users which tray is currently being used and when switching will occur, enabling effective user management while maintaining automatic operation.

Inventive Principle:
Principle #23Feedback

3Quantity of substance

If multiple paper feeding trays are used for large amount jobs, then paper availability is improved, but users cannot know which tray to refill or adjust

Engineering Contradiction:
Improvepaper availabilityVSAvoidtray status information
Core Design Contradiction:
Quantity of substanceVSLoss of information

Solution Approach 1:

The control section provides feedback information about each paper feeding tray's status and switching schedule, allowing users to identify which trays need refilling or adjustment before paper shortages occur.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system calculates and displays switching information in advance, enabling users to perform preliminary paper refilling and tray adjustments before the switching occurs or before paper runs out.

Inventive Principle:
Principle #10Preliminary action

4Extent of automation

If automatic switching is enabled without visibility, then the system operates autonomously, but users cannot disable switching to unadjusted trays

Engineering Contradiction:
Improveautonomous operationVSAvoidstable operation
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The display unit provides visibility into the automatic switching process, showing users which trays will be switched and when, enabling them to monitor for potential stability issues and intervene if needed.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

By displaying switching information in advance, users can identify trays that may be unadjusted or problematic before switching occurs, and take preliminary actions to ensure stable operation.

Inventive Principle:
Principle #10Preliminary action
