Solution Overview

Problem

Device change methods differ between two electronic devices, posing a challenge when transferring a profile or service during device changes, especially when the devices support different versions.

Innovation Solution

A method and apparatus for performing device changes by identifying the appropriate code for the target device's version, transmitting the necessary code to download the profile, and communicating with a profile server to facilitate the transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If device change is performed without version compatibility verification, then device change speed is improved, but data loss or service interruption occurs

Engineering Contradiction:
Improvedevice change speedVSAvoiddata integrity and service continuity
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system performs version compatibility verification, profile synchronization, and dependency checking before the actual device change operation. This preliminary action ensures that all necessary conditions are met (profiles are synchronized, versions are compatible, dependencies are resolved) before proceeding with the device change, thereby preventing data loss and service interruption while maintaining efficient device change speed.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If version compatibility verification is performed during device change, then data integrity is improved, but device change time increases

Engineering Contradiction:
Improvedata integrity and service continuityVSAvoiddevice change time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system automatically performs version compatibility verification, profile synchronization, and dependency resolution without requiring manual intervention. The apparatus self-manages the entire verification and preparation process, checking device versions, synchronizing profiles, and resolving conflicts automatically, thereby ensuring data integrity while minimizing the time overhead associated with manual verification procedures.

Inventive Principle:
Principle #25Self-service

3Reliability

If profiles are synchronized between devices, then service continuity is improved, but synchronization time and complexity increase

Engineering Contradiction:
Improveservice continuityVSAvoidprofile synchronization complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system introduces a profile synchronization mechanism that acts as an intermediary between the old and new devices. This intermediary automatically manages profile data transfer, version matching, and conflict resolution, ensuring service continuity while abstracting away the complexity of manual profile synchronization from the user. The synchronization process handles version differences and data conflicts automatically, reducing perceived complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If all profile versions are retained during device change, then version compatibility is improved, but storage requirements and processing complexity increase

Engineering Contradiction:
Improveversion compatibilityVSAvoidprofile data volume
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system changes the state of profile data by creating version-specific copies only when version conflicts are detected. Instead of retaining all profile versions indefinitely, the system transforms the profile data state based on version compatibility requirements - keeping only the necessary versions that are needed for compatibility, thereby maintaining adaptability while reducing unnecessary storage consumption and processing overhead.

Inventive Principle:
Principle #35Parameter changes
