Solution Overview

Problem

Existing cross-device content transfer methods are cumbersome, requiring users to upload and download files through cloud applications, which increases operational complexity and reduces user experience.

Innovation Solution

A cross-device content transfer method and apparatus that allows a first device to remotely access a second device by dragging an icon to a toolbar, enabling direct transfer of elements between devices without the need for simultaneous use of both devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users transfer files through cloud applications by uploading and downloading, then files can be transferred between devices, but the operational complexity increases and user experience deteriorates

Engineering Contradiction:
Improvecross-device content transfer operationVSAvoidtransfer process complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the file content from the cloud application context and enables direct dragging between devices. The toolbar with drag icons allows users to transfer files directly without going through cloud upload/download processes, simplifying the operation by removing unnecessary intermediate steps

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a toolbar as an intermediary element that facilitates direct file transfer between devices. The toolbar contains drag icons that act as mediators, allowing users to initiate transfers by dragging icons between device interfaces without requiring cloud application interactions

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If users switch between devices for file transfer, then files can be moved between devices, but time is lost due to device switching

Engineering Contradiction:
Improvefile transfer efficiencyVSAvoiddevice switching time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent displays a toolbar with drag icons in advance within the remote device interface. This preliminary preparation allows users to immediately drag files when the remote interface is displayed, eliminating the need to physically switch devices and reducing time loss

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If a toolbar is displayed to enable dragging, then cross-device transfer is simplified, but the display area is reduced

Engineering Contradiction:
Improvecontent transfer operationVSAvoiddisplay area
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The toolbar is designed as a dynamic element that can be adjusted in size and position. Users can resize the toolbar to balance between having enough control options visible and maintaining sufficient display area for content, allowing flexible adaptation to different usage scenarios

Inventive Principle:
Principle #15Dynamics

AI summary

Embodiments of this application provide a cross-device content transfer method and apparatus, and relate to the field of terminal technologies, in which in a case where a first device remotely accesses a second device, in response to an operation of dragging a first icon to a first toolbar, the first device displays a third interface and receives a first element indicated by the first icon and transmitted by the second device, a first folder of the first device includes the first element after the first element is transferred, and the third interface includes content displayed by the second device, so that the first device can conveniently transfer the first element from the second device to the first device based on a user's operation of dragging the first icon to the first toolbar, simplifying the cross-device content transfer method.
