File Sharing Method Using Parallel Device-to-Device Forwarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current file sharing methods between electronic devices are inefficient, requiring sequential transmission from the transmitting-end device to multiple receiving-end devices, leading to increased time and effort.
Innovation Solution
A method where the transmitting-end device sends a file to one receiving-end device, which then forwards it to others, reducing the need for sequential transmission and improving efficiency by allowing receiving-end devices to share files with each other after successful receipt.

Engineering Contradiction Analysis
1Productivity
If the transmitting-end device sequentially sends the file to each receiving-end device, then the file sharing process is simple to control, but the file sharing efficiency is low and the time consumption is high
Solution Approach 1:
The patent segments the file sharing process into multiple parallel transmission paths. Instead of one sequential path from the transmitting device to each receiving device, the system creates multiple simultaneous transmission channels where the first receiving device receives the file and then forwards it to the second receiving device, while the transmitting device simultaneously sends the file to the third receiving device. This segmentation of the transmission process enables parallel operations, improving overall file sharing efficiency and reducing total time consumption.
2Ease of operation
If the transmitting-end device sends the file to all receiving-end devices directly, then the control is centralized and easy to manage, but the time required for sharing increases with each additional device
Solution Approach 1:
The patent applies preliminary action by having the first receiving device prepare to forward the file to the second receiving device as soon as it receives the file from the transmitting device. This preliminary preparation of the forwarding action occurs in parallel with the transmitting device's simultaneous transmission to the third receiving device. By initiating the forwarding action preliminarily rather than sequentially, the system reduces the overall sharing duration while maintaining operational simplicity through automated forwarding protocols.

AI summary
In a file sharing method, a transmitting-end device receives a selection operation performed on identifiers of multiple receiving-end devices that include a first device, a second device, and a third device. Triggered by the selection operation, the transmitting-end device sends a to-be-shared file to the first device. Thereafter, the transmitting-end device sends the to-be-shared file to the third device. The transmitting-end device then indicates to the first device to send the to-be-shared file to the second device, or indicating to the second device to obtain the to-be-shared file from the first device.
