Electronic Device File Sharing Through Selective Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current file sharing methods between electronic devices involve sending multiple files one by one, which is inefficient.
Innovation Solution
A method that classifies files based on type and size, compressing certain files before sending, and using concurrent threads to send compressed and uncompressed files simultaneously, reducing data amount and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple files are sent one by one, then the file sharing process is simple to implement, but the sharing efficiency is low
Solution Approach 1:
The patent segments files into two categories: compressible files (first-type files) and non-compressible files (second-type files). This segmentation allows the system to apply different handling strategies to different file types, improving overall sharing efficiency by compressing suitable files while sending others directly.
Solution Approach 2:
The patent performs preliminary compression of the first-type files before the actual file sharing process. By pre-compressing files that can be compressed, the system reduces the total data量 to be transmitted, thereby improving sharing efficiency without adding complexity during the transmission phase.
2Quantity of substance
If all files are compressed before sending, then the data amount is reduced and sharing efficiency is improved, but the processing time and resource consumption increase
Solution Approach 1:
The patent applies local quality by selectively compressing only the first-type files (those suitable for compression) while leaving second-type files unchanged. This localized approach to compression reduces the total data amount for compression-eligible files without unnecessarily processing all files, thereby balancing data reduction with processing time.
Solution Approach 2:
The patent uses partial action by compressing only the subset of files that are appropriate for compression (first-type files) rather than compressing all files regardless of their characteristics. This partial compression strategy achieves data reduction for the most beneficial files while avoiding the time cost of compressing unsuitable files.
3Ease of manufacture
If files are classified and compressed sequentially, then the processing is straightforward, but the total processing time increases
Solution Approach 1:
The patent implements continuous useful action by performing file classification and compression operations concurrently with the file sending process. The compression of first-type files and the sending of files occur in parallel rather than sequentially, maintaining processing simplicity while significantly reducing total processing time through concurrent operations.
Solution Approach 2:
The patent introduces dynamics by enabling the system to adaptively classify and process files based on their characteristics during the sharing operation. The system dynamically determines which files to compress and which to send directly, optimizing the processing flow to reduce total time while maintaining operational simplicity.

AI summary
Embodiments of this application provide a file sharing method and an electronic device. The method is applied to a first electronic device, and includes: displaying a first interface including an identifier of a second electronic device; establishing a communication connection to the second electronic device when receiving a first operation that is on the first interface and that is performed by a user on the identifier of the second electronic device, where the second electronic device is configured to receive multiple to-be-shared files sent by the first electronic device; sequentially compressing a preprocessing-type file in the multiple to-be-shared files to obtain a compressed file; and sending a direct-sending-type file in the multiple to-be-shared files and the obtained compressed file to the second electronic device through a data channel corresponding to the communication connection, where the preprocessing-type file and the direct-sending-type file are obtained by classifying the multiple to-be-shared files according to a preset classification policy. The method can improve efficiency of a file sharing process.
