Solution Overview

Problem

Current mobile computing devices lack an intuitive and efficient method to seamlessly transition between single and multiple display modes, limiting user interaction with both home screen content and application content simultaneously.

Innovation Solution

Implementing a multiple display mode user interface that allows a home screen to be displayed on one display while application content is shown on another, enabling users to interact with both simultaneously through physical configuration changes or user input, such as sliding or folding the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single display is used to show all content, then the device structure remains simple, but users cannot access home screen content and application content simultaneously

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

Solution Approach 1:

The display system is segmented into a first display and a second display, allowing independent rendering of home screen content and application content. This segmentation enables simultaneous access to both content types while maintaining manageable complexity through modular display architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The multiple display system provides multi-functionality by enabling different display modes (single display mode and multiple display mode). The system can adapt between showing all content on one display or distributing content across multiple displays, offering universal access to various content types simultaneously.

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

2Ease of operation

If multiple displays are used to show different content simultaneously, then user interaction with home screen and applications improves, but the device structure becomes more complex

Engineering Contradiction:
Improveuser interaction efficiencyVSAvoiddisplay configuration complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The display system dynamically transitions between single display mode and multiple display mode based on user needs. The ease of operation is enhanced through dynamic content distribution, while the complexity is managed by allowing the system to adapt its configuration rather than requiring permanent complex hardware setup.

Inventive Principle:
Principle #15Dynamics

3Loss of information

If all content is displayed on one display, then the display system remains simple, but users must switch between home screen and applications losing context

Engineering Contradiction:
Improvecontext retentionVSAvoidinformation management complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

By segmenting the display system into first and second displays, home screen content and application content can be shown simultaneously in their respective display areas. This prevents information loss during switching while maintaining manageable complexity through spatial separation of content types.

Inventive Principle:
Principle #1Segmentation

4Area of stationary object

If a transparent display is used to show menu options, then space is saved, but the display area and visibility are reduced

Engineering Contradiction:
Improvedisplay areaVSAvoiddisplay visibility
Core Design Contradiction:
Area of stationary objectVSIllumination intensity

Solution Approach 1:

The patent assigns the first display area to home screen content and the second display area to application content, with each display providing full visibility and area for its designated content type. This segmentation avoids the visibility and area compromises of transparent displays while maintaining efficient space utilization through dedicated display regions.

Inventive Principle:
Principle #1Segmentation

AI summary

Various methods for implementing a multiple display mode are provided. One example method includes receiving an indication of a transition to a multiple display mode, and in response to at least receiving the indication of the transition to the multiple display mode, causing a home screen with home screen content to be displayed by a first display of a device. The example method may further include, in response to at least receiving the indication of the transition to the multiple display mode, causing application content provided by an application being implemented to be displayed by a second display of the device while the home screen with the home screen content is being displayed by the first display. Similar and related example methods and example apparatuses are also provided.
