Wi-Fi Direct File Transfer Compatibility Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Wi-Fi Direct file transfer method does not allow the receiving end to determine if a file is supported until after it has been completely received, leading to poor user experience due to potential file incompatibility issues.
Innovation Solution
The method involves the transmitting end sending the multimedia attributes of a file before transfer, allowing the receiving end to judge compatibility and prompt the user accordingly, enabling informed decision-making on whether to continue the transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the receiving end waits to receive the complete file before determining compatibility, then the file transfer process is simple, but the user experience deteriorates due to wasted transfer time and storage space for incompatible files
Solution Approach 1:
The patent applies preliminary action by sending file attribute information (such as format, resolution, bitrate) before the actual file transfer. The receiving end device checks compatibility based on these attributes in advance, allowing users to make informed decisions about whether to proceed with the transfer, thus avoiding waste of time and storage space on incompatible files
Solution Approach 2:
The patent segments the file transfer process into two distinct phases: first transmitting file attribute information separately, then transferring the actual file content. This segmentation allows the receiving end to evaluate compatibility independently before committing resources to the full transfer, resolving the contradiction between process simplicity and time efficiency
2Ease of operation
If the receiving end checks file compatibility after receiving the file, then the transfer process is straightforward, but storage space is wasted on incompatible files
Solution Approach 1:
The patent performs the compatibility check in advance by transmitting file attributes before the file content. The receiving end device compares these attributes against its supported formats and capabilities, enabling users to avoid storing incompatible files altogether while maintaining simple operation through automated attribute comparison
Solution Approach 2:
The patent implements feedback by providing compatibility information to the user before the transfer completes. The receiving end device analyzes the received attributes and provides feedback on whether the file is compatible, allowing users to make informed decisions about whether to proceed with receiving the full file, thus preventing storage waste

AI summary
A method for transferring files and apparatus through Wi-Fi Direct are provided. The method includes: an obtaining step, for obtaining a multimedia attribute of a file to be transferred; a sending step, for sending the multimedia attribute obtained in the obtaining step; a receiving step, for receiving information of the multimedia attribute of the file to be transferred; and a judgment step, for judging, according to the information of the multimedia attribute received in the receiving step, whether a receiving end supports the type of the file to be transferred. The embodiment of the patent document solves the problem that the receiving end may know whether to support the type of the file only after completely receiving the file or performing an opening operation, thus leading to inconvenient use, which improves the user experience.
