Solution Overview

Problem

Conventional mobile devices have limited screen space, which restricts their ability to provide an optimal display environment for multimedia and internet functions, especially when multiple applications are used simultaneously.

Innovation Solution

A mobile device with dual display units that can either combine into a single larger screen or operate independently, allowing users to select a dual mode for displaying search results on either one or both screens based on user input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a single large display unit is used to provide optimal display environment for multimedia and internet functions, then the display area and quality are improved, but the device size and complexity increase

Engineering Contradiction:
Improvedisplay areaVSAvoiddevice structure
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The display system is segmented into two separate display units (first display unit and second display unit) that can function independently or together. This segmentation allows the device to provide a large total display area while maintaining a compact form factor, as the displays are distributed across two units rather than requiring one large unit.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second display unit is positioned to overlap with the first display unit when the device is closed, creating a nested configuration. This nesting allows both displays to be housed within a compact device body, providing large display area without increasing the overall device footprint.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If multiple applications are used simultaneously on a single screen, then the device functionality is improved, but the screen space becomes insufficient

Engineering Contradiction:
Improvemulti-application capabilityVSAvoidscreen space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The display functionality is segmented across two independent display units, allowing different applications to run simultaneously on each display. This enables multi-application capability without requiring a single large screen, as each display unit can be dedicated to specific applications or tasks.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dual display system provides multi-functionality by enabling various operating modes: both displays can show different applications simultaneously, one display can mirror the other, or the displays can be used in different configurations based on user needs, thereby enhancing adaptability.

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

3Adaptability or versatility

If dual display units are used to provide flexible display options, then the adaptability and user convenience are improved, but the device complexity increases

Engineering Contradiction:
Improvedisplay mode flexibilityVSAvoidcontrol system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The dual display system implements dynamic switching between different operating modes (first mode with both displays active, second mode with single display, third mode with overlapping displays when closed). This dynamic adaptability allows the device to adjust its display configuration based on usage context, providing flexibility while managing complexity through automated mode selection.

Inventive Principle:
Principle #15Dynamics

AI summary

A mobile device with dual display units and a method for displaying screen images are provided. The two display units cooperate to serve as one combined display device and display one screen image thereon. Alternatively, the two display units can be independently operated and can display different screen images thereon, respectively. The method includes displaying screen images according to an execution of a particular mode on at least one of first and second display units, and displaying a screen image, searched for according to an execution of a search function, on at least one of the first and second display units, based on whether a dual mode is selected.
