Solution Overview

Problem

The existing methods for sharing files between electronic devices during calls are cumbersome and time-consuming, leading to poor convenience and efficiency.

Innovation Solution

A method and system that enables screen projection connection between electronic devices, allowing users to share objects by inputting a target identifier on the projected content, which controls the transmission of the object to a third device without multiple inputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional file sharing method is used during calls, then file sharing function is achieved, but the operation process is cumbersome and time-consuming

Engineering Contradiction:
Improveconvenience of file sharingVSAvoidtime required for file sharing
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent applies preliminary action by establishing screen projection connection before the actual file sharing operation. The caller's device projects its screen to the callee's device in advance, allowing the callee to directly see and select files for sharing without navigating through multiple menus. This preliminary setup eliminates the need for subsequent complex operations during the sharing process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses screen projection as an intermediary mechanism between the caller and callee. Instead of direct file transfer through complex application interfaces, the screen projection creates a visual intermediary that allows the callee to see and select files directly on their own device, simplifying the interaction and reducing the number of steps required.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If traditional file sharing method is used during calls, then file sharing function is achieved, but the operation process is complex

Engineering Contradiction:
Improvesimplicity of sharing processVSAvoidcomplexity of sharing operations
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The screen projection connection is established in advance as a preliminary action, creating a simplified interface for subsequent file selection. This preliminary setup transforms a complex multi-step process into a simple visual selection task where the callee can directly interact with the projected screen to initiate file sharing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses screen projection to create a visual copy of the caller's device interface on the callee's device. This copying allows the callee to interact with what appears to be the original interface directly on their own screen, eliminating the need to navigate through separate sharing menus and reducing operational complexity.

Inventive Principle:
Principle #26Copying

3Productivity

If screen projection connection is established, then file sharing convenience is improved, but additional connection setup is required

Engineering Contradiction:
Improvefile sharing efficiencyVSAvoidconnection setup requirements
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The screen projection connection serves multiple functions: it enables both screen sharing and file sharing operations through a single connection mechanism. This multi-functionality means that once the projection connection is established, various file operations can be performed without requiring separate connection setups, improving overall efficiency while managing complexity through consolidation.

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

AI summary

Disclosed are a sharing method and apparatus and an electronic device. The sharing method includes: receiving screen projection content transmitted by a second electronic device in a case that a first electronic device and the second electronic device are in a screen projection connection and the second electronic device is in a call with a third electronic device; displaying the screen projection content; receiving a first input from a user with regard to a target identifier and a display area of the screen projection content, where the target identifier is used for indicating a target object; and controlling, in response to the first input, the second electronic device to transmit the target object to the third electronic device.
