Email Attachment Management via File Server Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing messaging systems face challenges in efficiently exchanging large email attachments due to file size limitations, leading to overburdened resources and inconsistent attachment handling across different service providers.
Innovation Solution
Implementing a method where email attachments are sent to a file server instead of being included in emails, allowing recipients to retrieve attachments via links embedded in emails, with options for automatic or manual retrieval and expiration dates for links to manage storage and usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If attachments are included directly in email messages, then email clients can access attachments locally, but file size limitations are imposed and messaging system resources are overburdened
Solution Approach 1:
The patent extracts attachments from email messages and stores them separately on a file server. Instead of embedding attachments within email messages, the system separates the attachment data from the message content, allowing emails to contain only references (URLs) to attachments. This resolves the contradiction by enabling large attachment files without overburdening the messaging system, as the messaging system only handles lightweight reference data rather than actual attachment content.
Solution Approach 2:
The patent introduces a file server as an intermediary component between the email system and attachments. The file server handles storage, management, and delivery of attachment files, while the email system focuses on message delivery. This intermediary architecture allows the messaging system to circumvent file size limitations without directly handling large attachment files, thereby maintaining resource efficiency while supporting large attachments.
2Adaptability or versatility
If different messaging providers impose varying attachment size limits, then each provider can manage its own resources, but users experience inconsistent attachment handling across providers
Solution Approach 1:
The patent implements a universal attachment management approach where attachments are stored on a shared file server accessible by multiple messaging providers. Instead of each provider maintaining separate attachment storage and management systems, the file server provides a common platform that all providers can utilize. This universal architecture enables consistent attachment handling across different providers while reducing overall system complexity, as providers no longer need to implement their own attachment storage infrastructure.
3Quantity of substance
If attachments are stored on a file server and accessed via links, then file size limitations are circumvented, but additional retrieval steps are required
Solution Approach 1:
The patent performs preliminary actions by automatically generating and embedding retrieval links within email messages before delivery. Instead of requiring users to manually locate or request attachments, the system pre-places accessible links directly in the email content. This preliminary embedding of retrieval information maintains ease of operation, as users can access attachments through convenient in-email links without additional retrieval steps, while still benefiting from the file server's ability to handle large files.

AI summary
A method and system for exchanging email attachments is disclosed. An attachment can be sent to one or more recipients using a file hosting service. In this way, instead of including the attachment with the email, the attachment is sent and stored on a file server. The attachment can later be retrieved by the email's recipients using a link that is included in the email. The link can be embedded in the email's header or body. In one case, the attachment is automatically retrieved from the file server using the link. In another case, a recipient can manually retrieve the attachment from the file server using the link. A link can be associated with an expiration date such that when a link expires, the link can no longer be used to retrieve the attachment.
