Solution Overview

Problem

Existing electronic devices with dual systems cannot exchange data between them, leading to poor user experience due to separate and disconnected operation.

Innovation Solution

Implementing controls on the application home screen for file migration between main and subsystem applications, along with identity verification and multi-task display to ensure secure data exchange and system switching.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If two separate systems are set in electronic devices to meet requirements of different users, then user privacy and security are improved, but data exchange between systems becomes impossible and user experience deteriorates

Engineering Contradiction:
Improvesystem securityVSAvoiduser experience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a file management interface as an intermediary between the two separate systems. This interface includes controls for moving files in and out, allowing data exchange between systems without compromising their separation. The intermediary enables communication and data transfer while maintaining the security boundaries of the original systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If controls for file migration are added to enable data exchange, then user experience is improved, but system complexity increases

Engineering Contradiction:
Improvedata exchange capabilityVSAvoidsystem architecture
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The file management interface is designed to serve multiple functions within the existing system architecture. It not only enables data exchange between systems but also provides file management capabilities, category filtering, and system switching functions. This multi-functionality reduces the need for separate dedicated components for each function.

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

Solution Approach 2:

The patent adds a new dimension of interaction by introducing a file management interface layer between the two systems. Instead of modifying the core system architecture, it creates a new operational dimension where file migration and system switching can occur without affecting the fundamental separation and security of the original systems.

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

3Reliability

If identity verification is implemented for system switching, then security is improved, but operation speed decreases

Engineering Contradiction:
Improvesystem switching securityVSAvoidsystem switching time
Core Design Contradiction:
ReliabilityVSSpeed

Solution Approach 1:

The system performs identity verification in advance when switching between systems. By verifying user identity before allowing system switching or data access, the patent ensures security requirements are met while streamlining subsequent operations. The preliminary verification prevents repeated authentication checks during data exchange operations.

Inventive Principle:
Principle #10Preliminary action

AI summary

This application provides a data exchange method, an electronic device, and a storage medium, and relates to the field of terminal application technologies. In this method, a parallel space is set in a main system, and processes of creating, enabling, exiting, erasing, moving data into, and moving data out of the parallel space are provided. Specifically, when the parallel space is in use, the parallel space may directly enable data that can be migrated by the main system, so that data in the main system is migrated to the parallel space, data exchange between the main system and the parallel space is achieved, and data exchange is more convenient and faster.
