Solution Overview

Problem

Conventional electronic devices require manual user intervention to enter a split-screen mode, leading to a cumbersome operation process and limited functionality, particularly in cross-application scenarios.

Innovation Solution

An electronic device is designed to automatically enable a split-screen display mode based on a user's operation within a task, allowing seamless transition between full-screen and split-screen modes without additional manual input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual triggering is used to enter split-screen mode, then the device can display multiple applications simultaneously, but the operation process becomes cumbersome and intelligence is reduced

Engineering Contradiction:
Improvesplit-screen display capabilityVSAvoidoperation process complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically detects when a user intends to switch tasks and autonomously enters split-screen mode without requiring manual activation. The electronic device monitors task switching operations and automatically configures the split-screen display, making the system serve itself rather than requiring continuous user intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system prepares the split-screen display configuration in advance by detecting task switching intentions. When the user performs a task switching operation, the system has already prepared the split-screen mode and can immediately activate it, eliminating the need for separate manual activation steps.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If manual triggering is used to enter split-screen mode, then the device can display multiple applications simultaneously, but the operation process becomes cumbersome and time-consuming

Engineering Contradiction:
Improvesplit-screen display capabilityVSAvoidtime for mode switching
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system detects task switching operations and automatically activates split-screen mode in response, eliminating the time required for manual mode activation. By monitoring task switching intentions and automatically configuring split-screen display, the system reduces the time loss associated with mode transitions.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If automatic task switching is enabled, then operation efficiency is improved, but the device cannot automatically enter split-screen mode for cross-application scenarios

Engineering Contradiction:
Improvetask switching efficiencyVSAvoidcross-application split-screen capability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system combines automatic task switching detection with automatic split-screen activation. When the user performs a task switching operation, the system autonomously determines whether to enter split-screen mode and configures the display accordingly, enabling both high productivity and cross-application split-screen versatility.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent merges the task switching function with the split-screen mode activation function. Instead of treating them as separate operations, the system combines them into a unified process where task switching automatically triggers split-screen configuration, achieving both efficiency and adaptability.

Inventive Principle:
Principle #5Merging (Combining)
