Display Input Device Logout Key Size Maintenance

Solution Overview

Problem

Image forming apparatuses often remain in a login state, leading to potential unauthorized use due to users forgetting to log out, and existing solutions do not effectively prompt users to perform logout operations without reducing convenience.

Innovation Solution

A display input device with a touch panel and control portion that displays a logout key in the login state, maintaining the logout key's size while reducing other screen elements, prompting users to perform a logout operation through reduction processing based on a predetermined processing start time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the display screen is switched to a logout confirmation screen when a start key is pressed, then users are prompted to perform logout operations, but the user interface complexity increases and user convenience is reduced

Engineering Contradiction:

Improvelogout operation prompt effectivenessVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies local quality by making only the logout key maintain its original display size while reducing other screen elements. This selective size maintenance creates a visual hierarchy that draws attention to the logout function without requiring a complete screen switch, thus prompting logout operations while maintaining user convenience through a seamless interface.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by dynamically adjusting the display sizes of screen elements based on the detected job type. When a copy job is detected, the system reduces non-logout elements while maintaining logout key visibility, creating an adaptive interface that responds to user context without fixed screen transitions.

Inventive Principle:

Principle #15Dynamics

2Area of stationary object

If all screen elements are reduced in size, then more content fits on the screen, but the logout key becomes less visible and user interaction with it is reduced

Engineering Contradiction:

Improvescreen content densityVSAvoidlogout key visibility

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The patent applies local quality by making only the logout key maintain its original display size while reducing other screen elements. This selective size maintenance creates a visual hierarchy that draws attention to the logout function without requiring a complete screen switch, thus prompting logout operations while maintaining user convenience through a seamless interface.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If the logout key size is reduced along with other elements, then the screen layout is consistent, but the logout operation is not effectively prompted

Engineering Contradiction:

Improvescreen layout consistencyVSAvoidlogout operation prompt effectiveness

Core Design Contradiction:

Stability of the object's compositionVSReliability

AI summary

A display input device includes a display portion, a touch panel portion and a control portion, and when in a login state, a predetermined processing start time is reached, reduction processing is performed in which in a screen being presently displaced, a display size of a logout key is maintained and in which a display size of a reduction target element that is a screen element other than the logout key is reduced.
