Solution Overview

Problem

Existing methods for switching user equipment (UE) require an intermediary computer for data and settings transfer, which may not be convenient or possible in all scenarios.

Innovation Solution

A method that allows direct transfer of data and settings between UEs using a removable memory with a unique value, enabling wireless communication and synchronization without an intermediary device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an intermediary computer is used to transfer data between UEs, then data transfer reliability is improved, but device complexity and operational convenience deteriorate

Engineering Contradiction:
Improvedata transfer reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses a removable memory module as an intermediary carrier to transfer data between UEs. The memory module stores data from the first UE and presents it to the second UE, eliminating the need for a complex intermediary computer system while maintaining reliable data transfer through physical media exchange.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the data transfer function from the complex intermediary computer system and isolates it into a simple removable memory module. This extraction reduces system complexity by removing the need for desktop manager software, file archiving mechanisms, and intermediate storage infrastructure while preserving the essential data transfer capability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If an intermediary computer is used for data transfer, then data security is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvedata securityVSAvoidoperational convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The removable memory module autonomously performs the data transfer function without requiring user interaction with complex computer software. The user simply inserts the memory module into the second UE, and the system automatically handles data presentation and synchronization, eliminating the need for manual file management operations.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If direct wireless transfer between UEs is implemented, then ease of operation is improved, but reliability deteriorates

Engineering Contradiction:
Improveoperational convenienceVSAvoiddata transfer reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a removable memory module as a physical intermediary that bridges the gap between direct transfer convenience and reliable data transmission. The memory module serves as a tangible data carrier that can be physically secured and transferred, combining the simplicity of direct user action with the reliability of stable data storage and presentation.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Secure transfer of data and settings from one user equipment (UE) to another UE. The embodiments provide for a user equipment (UE) including a non-volatile memory, a removable memory, and a processor. The processor is configured, responsive to receiving a command to perform a swap operation, to store a unique value in the non-volatile memory and the removable memory, such that when the removable memory is transferred to a second UE in communication with the UE, the UE uses the unique value in transferring data between the UE and the second UE. The embodiments also provide for a method and a computer readable storage medium or non-transitory storage medium for implementing a process for accomplishing the above.
