Solution Overview

Problem

Existing technologies face challenges in efficiently transmitting and displaying content across interconnected electronic devices, particularly when dealing with complex display contents like web pages, where identifying and responding to drag operations across devices is difficult.

Innovation Solution

A method and apparatus that obtain node information and display data of a display content, generate a target image representing a target object based on this information and operation data, and send the target image through a connection channel in response to operation information from a target device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing technologies are used for cross-device content transmission, then device interconnection is achieved, but efficient transmission and display of complex display content (like web pages) cannot be realized

Engineering Contradiction:
Improvecontent transmission efficiencyVSAvoidcomplex display content support
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent segments display content into discrete node information units that can be independently identified and transmitted. Each node represents a specific element within the display content, allowing selective extraction and transmission of relevant portions rather than transmitting entire complex display contents, thereby improving transmission efficiency while maintaining support for complex content types.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates target images as simplified copies of the original display content nodes. Instead of transmitting the complete original display content (such as entire web pages), the system generates and transmits target images that represent specific nodes, reducing transmission data volume while preserving the essential visual information needed for cross-device display.

Inventive Principle:
Principle #26Copying

2Ease of operation

If drag operations are implemented across interconnected devices, then user interaction is improved, but identifying and responding to drag operations becomes difficult

Engineering Contradiction:
Improvecross-device drag operationVSAvoiddrag operation detection
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The patent implements a feedback mechanism where the first electronic device sends node information and displays target images in response to drag operations detected on the second electronic device. The system continuously monitors for drag operations, processes them by generating appropriate target images, and provides visual feedback through display, creating a closed-loop interaction system that simplifies cross-device drag operations while making detection straightforward through structured event handling.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If image saving support is required in third-party applications, then complete functionality is achieved, but system complexity and requirements increase

Engineering Contradiction:
Improvefunctionality completenessVSAvoidapplication requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary processing layer that generates target images from node information without requiring third-party applications to implement image saving functionality. The system acts as a mediator between the display content and the transmission process, handling image generation and transmission independently of the original application's capabilities, thereby maintaining functionality while reducing complexity requirements for third-party applications.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A processing method includes: obtaining node information of display data of a display content, the node information representing the display content, and the display data being used to present the display content for display output; in response to first operation information, based on the node information and the display data, generating a target image, the target image representing a target object; and in response to second operation information, sending the target image through a connection channel. The first operation information and the second operation information are both from a target device connected through the connection channel, and are generated in two stages of performing a same operation on the target object.
