Solution Overview

Problem

Existing portable information processing devices require user intervention to select display modes, leading to increased operational burden and reduced convenience when connecting to external display devices without a network.

Innovation Solution

A portable information processing device that automatically switches between mirror display and expanded display modes based on external display connections and application start-ups, eliminating the need for user-selective mode operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the user manually selects display modes (clone display or multidisplay), then the device can adapt to different usage scenarios, but the operational burden on the user increases and convenience lowers

Engineering Contradiction:
Improvedisplay mode adaptabilityVSAvoidoperational burden
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The control portion automatically determines and switches between clone display mode and multidisplay mode based on detected conditions (external display connection status and application type), eliminating the need for manual user selection. The system serves itself by autonomously adapting the display configuration to the current usage scenario.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The display mode is made dynamic and automatically adjustable based on real-time conditions. The control portion continuously monitors external display connection status and application information, then dynamically switches between clone display mode and multidisplay mode without requiring user intervention, making the system responsive to changing conditions.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the device automatically switches display modes based on connection and application status, then user convenience improves, but the device complexity increases

Engineering Contradiction:
Improveuser convenienceVSAvoidcontrol logic complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control portion is pre-programmed with decision logic that automatically determines the appropriate display mode based on predetermined conditions (external display connection status and application type). This preliminary configuration of control logic enables automatic mode switching without requiring complex real-time user decisions, simplifying the user interface while maintaining sophisticated adaptive behavior.

Inventive Principle:
Principle #10Preliminary action

AI summary

Disclosed is a portable information processing device which can improve convenience by reducing an operational burden resulting from a selecting operation of the user. A control portion (18a) of the portable information processing device (1) selects, at least on the basis of that an external display device (5) is connected and a prescribed application is being started, a second mode from a first mode causing an external display device to display the same data as the data displayed on an built-in display portion (10) and the second mode causing the built-in display portion to display data different from the data displayed on the external display device.
