Email Sending Device Segments Large File Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic mail systems face challenges in efficiently sending large-volume data, such as image files or sound data, as they can overload the system and require complex FTP processes, which are difficult for common users to manage.
Innovation Solution
The system allows users to transmit large files to a predetermined location on an Internet server and send an email with a link to download the file, rather than attaching the file directly to the email, using a digital color multifunction product that supports FTP and HTTP protocols, enabling easy sharing of image data across networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large-volume data is attached directly to electronic mail, then the receiver can obtain the data directly, but the email system becomes overloaded and may crash or become slow
Solution Approach 1:
The patent segments the data transmission process into two separate steps: first, the file is uploaded to an FTP server; second, a notification email containing download information is sent. This segmentation allows the email system to handle only small notification messages while large files are transmitted through the FTP server, resolving the contradiction between data transmission capability and system stability.
2Reliability
If FTP is used to transmit large-volume data, then the email system remains lightweight, but the process becomes complicated and difficult for common users to manage
Solution Approach 1:
The patent introduces an FTP server as an intermediary between the sender and receiver. The sender simply uploads files to the server through a standardized interface, and the receiver downloads files from the server using standard FTP clients. This intermediary approach maintains system stability while providing a standardized, user-friendly interface that simplifies the transmission process for common users.
3Reliability
If attachment volume limits are imposed on email, then system load is reduced, but the sender must divide large files into multiple pieces and the receiver must combine them
Solution Approach 1:
The patent extracts the large file storage and transmission function from the email system and places it in a dedicated FTP server. The email system only handles small notification messages, while the FTP server handles all large file operations. This extraction eliminates the need for dividing and combining files, as the FTP server manages the complete file transmission process, thereby reducing data handling complexity.

AI summary
When sending an electronic file to a receiver, the file is first transmitted to a predetermined location. Then, an electronic mail is created and sent to the receiver. This electronic mail contains information that makes it possible for the receiver to download the file from the location. Finally, the electronic mail is sent to the receiver without attaching the file.
