Solution Overview

Problem

Existing mobile devices limit users to operating one application at a time, making it challenging to simulate traditional experiences that require multi-tasking and content sharing between applications, especially for complex content.

Innovation Solution

A split-screen display mode that partitions the screen into multiple portions to display content from different applications simultaneously, allowing for customization of layout, resizing, and seamless content sharing between applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single display screen is used in a computing device, then the device structure remains simple, but the screen must display multiple types of information (messaging, media playback, notifications) which can lead to information overload and reduced user experience

Engineering Contradiction:
Improvedisplay information typesVSAvoidinformation management
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The display interface is segmented into multiple independent display areas (first display area and second display area) that can simultaneously show different types of information. Messaging applications are displayed in one area while media playback or notifications are displayed in another area, allowing users to manage multiple information types without overload.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple display screens are used to display different information types simultaneously, then user experience improves, but the device complexity and cost increase

Engineering Contradiction:
Improvesimultaneous information displayVSAvoiddisplay system structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of adding multiple physical display screens in different directions, the patent utilizes the spatial dimension of a single screen by dividing it into multiple display areas. This allows simultaneous display of messaging, media playback, and notifications on one screen without increasing device complexity or cost.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If a single display area is used for all applications, then the display system remains simple, but switching between messaging and media playback requires pausing one application, reducing productivity

Engineering Contradiction:
Improveapplication switching efficiencyVSAvoiddisplay management system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the display functionality for messaging applications and media playback into a single unified display system with multiple display areas. This allows both applications to run simultaneously without pausing either one, improving productivity while maintaining a unified display management system rather than requiring separate display hardware.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If the display screen is divided into multiple areas for different applications, then simultaneous information display improves, but the interface design and management complexity increases

Engineering Contradiction:
Improvemulti-application displayVSAvoidinterface management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display management system is designed with universal functionality to handle multiple application types (messaging, media playback, notifications) across multiple display areas. The same interface management mechanisms control all display areas, providing a unified approach rather than requiring separate management systems for each application type.

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

AI summary

Introduced here are split-screen implementation techniques that can allow a user to view and interact with the user interfaces of two or more applications simultaneously. Each of the two or more applications can be displayed within its own portion of two or more portions. A split-screen mode can be activated by a user by opening a split-screen application and selecting the applications to be used. Once within the split-screen mode, the user can customize the layout by adjusting the size of each portion and/or moving the application between the portions. Further, when within the split-screen mode, the user can share content from one application to another by selecting and dragging the content. The split-screen mode can also be implemented on a foldable device. The folding of the device can be used as a trigger to initiate split screen mode and the folding line can be used a border between portions.
