Solution Overview

Problem

Existing image formation apparatuses lack an efficient method to differentiate and manage print settings between normal toner and decolorable toner, which hinders the reuse of printed paper.

Innovation Solution

A method for controlling an information processing apparatus to switch between different print setting displays based on whether non-decolorable or decolorable recording material is used, allowing users to select appropriate settings for each toner type.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single print setting display is used for both normal toner and decolorable toner, then the device complexity is reduced, but the ease of operation deteriorates because users cannot select appropriate settings for each toner type

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The print setting display is segmented into two distinct modes: a first display for normal toner settings and a second display for decolorable toner settings. The control unit switches between these displays based on the selected toner type, allowing users to see only the relevant settings for their chosen toner. This segmentation resolves the contradiction by providing tailored settings for each toner type without requiring users to navigate through all possible settings simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display configuration is made dynamic by implementing automatic switching between the first and second displays based on the toner type selection. When the user selects normal toner, the first display is shown; when decolorable toner is selected, the second display is shown. This dynamic adaptation resolves the contradiction by adjusting the interface complexity in real-time based on user choices, providing ease of operation without permanently increasing device complexity.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If separate print setting displays are provided for normal toner and decolorable toner, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

A single control unit performs multiple functions: it manages both the first display for normal toner and the second display for decolorable toner, and automatically switches between them based on selection. This multi-functionality resolves the contradiction by providing specialized displays for each toner type without requiring separate physical devices, thus improving ease of operation while avoiding excessive increase in device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The control unit acts as an intermediary that mediates between the user's toner type selection and the appropriate display configuration. It receives the selection input, determines which display mode is appropriate, and switches the display accordingly. This intermediary function resolves the contradiction by automating the complexity management, allowing specialized displays to be provided without burdening the user with complex manual configuration.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If automatic switching between displays is implemented, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system provides self-service by automatically detecting the toner type selection and switching the display configuration without requiring user intervention. The control unit monitors the selection state and autonomously transitions between the first and second displays. This self-service mechanism resolves the contradiction by improving ease of operation through automation while keeping the control logic integrated within the existing control unit, thus limiting the increase in device complexity.

Inventive Principle:
Principle #25Self-service

AI summary

A method for controlling an information processing apparatus capable of communicating with an image formation apparatus including a processor capable of controlling print processing using at least one of a non-decolorable recording material and a decolorable recording material, includes displaying a printer driver configured to transmit a print job to the image formation apparatus, and controlling switching of the printer driver between a first display in a case where the non-decolorable recording material is used and a second display in a case where the decolorable recording material is used.
