Solution Overview

Problem

Existing electronic devices, such as mobile phones, are limited in their ability to simultaneously display and run multiple applications in split-screen mode, leading to complex operation procedures and reduced user experience.

Innovation Solution

A method for combining multiple applications into a single 'combined application' that allows simultaneous starting and display of multiple applications in split-screen windows, enabling data sharing and simplifying user operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple applications are started independently in split-screen mode, then each application can be displayed in separate windows, but the operation procedure becomes complex and time-consuming

Engineering Contradiction:

Improveoperation procedureVSAvoidtime to start applications

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent combines multiple applications into a single 'combined application' entity. When the user launches this combined application, it automatically starts all constituent applications and arranges them in split-screen windows simultaneously. This merging approach allows one operation to achieve what previously required multiple sequential operations, directly resolving the contradiction between operational simplicity and time consumption.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system performs preliminary actions by pre-configuring the combination of applications and their intended display arrangements. When the combined application is launched, the system has already prepared the startup sequence and window arrangement, enabling simultaneous launching and automatic split-screen display without requiring user intervention during the startup process.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If a third application is added to split-screen display, then more applications can be run simultaneously, but floating windows overlay and affect user experience

Engineering Contradiction:

Improvenumber of applications displayedVSAvoiduser experience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts the display arrangement based on the number of applications being launched. When applications are combined and launched, the system automatically determines the appropriate split-screen configuration (e.g., two-half split for two applications, three-region split for three applications) and allocates display regions accordingly. This dynamic adaptation ensures that all applications are displayed in proper split-screen windows rather than overlapping floating windows, maintaining user experience while increasing adaptability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes display parameters such as window position, size, and arrangement based on the number of applications in the combined application. By adjusting these display parameters automatically, the system ensures that each application receives an appropriate display region in the split-screen mode, preventing overlay issues and maintaining good user experience regardless of how many applications are simultaneously displayed.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If applications are started sequentially rather than simultaneously, then each application can be properly initialized, but the overall process takes longer time

Engineering Contradiction:

Improveapplication initializationVSAvoidspeed of starting applications

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary preparation by pre-configuring the combined application structure and startup sequence before the user launches it. This allows the system to execute multiple application initializations in a coordinated manner, ensuring proper initialization while reducing the perceived time through parallel processing and optimized startup routines.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous useful action during the startup process by launching applications in an optimized sequence while simultaneously arranging their display windows. Rather than completing one application entirely before starting the next, the system continues the useful action of window arrangement and initialization in parallel where possible, ensuring reliable initialization while improving overall startup speed.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

The present disclosure relates to methods and devices for combining and simultaneously starting a plurality of applications. In one example method, a plurality of applications are combined to generate a combined application. A user taps an icon of the combined application to simultaneously start and run an interface of each of the plurality of applications. Start speeds, color styles, and the like of the plurality of applications are synchronized by default. In addition, the interface of each of the plurality of applications is automatically displayed in a split-screen window, and each of the plurality of applications enables data sharing space for the plurality of applications.
