File Download Resumption via Universal Format Conversion
Solution Overview
Problem
Current file download methods, especially using browsers, result in inconvenience and resource waste when downloads are interrupted, as incomplete files are abandoned, and switching to different tools requires re-downloading, leading to inefficiency and time consumption.
Innovation Solution
A method and device that convert incompletely downloaded files from one download tool to a format recognizable by another, allowing seamless resumption of downloads using different tools, utilizing format conversion tables and mapping tables to identify and retrieve the files for continued download.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a browser is used to download data, then no additional download tool software is required and operations are simple, but once an exception occurs the downloaded data must be abandoned and re-downloading is required
Solution Approach 1:
The patent changes the file format parameter of incompletely downloaded files from browser-specific formats to a universal format that multiple download tools can recognize. This allows the download state to be preserved and transferred between different download tools, eliminating the need to re-download when switching tools.
Solution Approach 2:
The patent creates a universal file format that can be recognized by multiple download tools (browser, Thunder, FlashGet, etc.). This universal format serves as a common interface that allows any download tool to continue downloading files started by other tools, providing multi-functional compatibility across different download applications.
2Productivity
If a download tool is used to download a file, then download speed may be improved, but if the user switches to another download tool the already downloaded data is abandoned
Solution Approach 1:
The patent changes the file format parameter to a universal format that preserves download progress. This allows users to switch between download tools (from slower to faster tools) without losing already downloaded data, as the universal format enables any tool to recognize and continue the download from the existing progress.
Solution Approach 2:
The patent makes the download system dynamic by allowing flexible switching between different download tools while preserving download state. The universal file format enables the download process to be transferred between different tools, making the system adaptable to changing user needs for speed or functionality without losing progress.
3Adaptability or versatility
If different download tools use different file formats to store incompletely-downloaded files, then each tool can manage its own files, but conversion between tools is impossible
Solution Approach 1:
The patent introduces a universal file format as an intermediary between different download tools. Each tool can convert its proprietary format to this universal format, which serves as a common language enabling interoperability. This intermediary format allows tools to maintain their own management capabilities while achieving compatibility through conversion.

AI summary
The present invention relates to a method and a device for resuming download. The method for resuming download comprises: converting a file incompletely downloaded by a first download tool to a file identifiable to a second download tool, so that the second download tool resumes downloading the incompletely-downloaded file, wherein the first download tool and the second download tool are different download tools. The present invention implements relay download of different download tools, and can be applied to file download, so as to avoid wasting network resources and time of users.
