Solution Overview

Problem

Electronic devices struggle to adjust the display of floating windows according to user requirements when screen-splitting, affecting user experience.

Innovation Solution

The electronic device displays a first interface with a first and second window, and a slide bar to resize them, and can switch to different floating window states based on user operations, including half-screen, full-screen, and bottom states, and can flip or switch windows based on folding angles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple full-screen applications are run simultaneously, then application functionality and user choice are improved, but system resource consumption and device complexity increase

Engineering Contradiction:
Improveapplication functionalityVSAvoidsystem resource consumption
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display screen is segmented into multiple virtual display areas, each independently displaying a different full-screen application. This allows multiple applications to run simultaneously in separate virtual spaces without requiring multiple physical displays, thus improving application functionality while managing system resources efficiently through virtualization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension of virtual space management by creating multiple virtual display areas within the single physical display boundary. This dimensional transformation enables full-screen applications to coexist by allocating them different virtual spatial coordinates, resolving the conflict between running multiple full-screen apps and system resource constraints.

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

2Adaptability or versatility

If virtual display areas are added for multiple full-screen applications, then application versatility is improved, but interaction complexity and user confusion increase

Engineering Contradiction:
Improveapplication versatilityVSAvoiduser interaction
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Different virtual display areas are distinguished by unique background colors or visual themes. This visual differentiation helps users quickly identify and switch between different virtual spaces and their associated applications, reducing interaction complexity and preventing user confusion while maintaining high application versatility.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent introduces a virtual display area management mechanism that acts as an intermediary between the user and multiple full-screen applications. This mediator provides unified control interfaces for creating, switching, and managing virtual display areas, simplifying user interactions while enabling diverse application configurations.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If background applications are allowed to continue running, then application functionality is maintained, but power consumption and processing resources increase

Engineering Contradiction:
Improveapplication functionalityVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the runtime state of applications in virtual display areas based on user interaction. When a virtual display area is not the active focus, its applications can be suspended or placed in a low-power state, reducing power consumption and processing resources while maintaining the capability to quickly resume functionality when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements periodic checks or triggers to manage application states in virtual display areas. Applications can be periodically suspended when not in use and activated when needed, creating a rhythm of resource allocation that maintains application functionality while significantly reducing overall power consumption and processing overhead.

Inventive Principle:
Principle #19Periodic action
