Solution Overview

Problem

Current email systems fail to track and make accessible shared links, attachments, and images beyond the intended recipients, limiting their visibility and usage.

Innovation Solution

An email system that rewrites all links, attachments, and images into public, short URLs, tracks their access, and integrates them into a public profile associated with the email account, allowing public accessibility and providing features like deduping, indexing, and tracking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If email systems use private URLs for attachments and images, then security and access control are improved, but public sharing and tracking capabilities deteriorate

Engineering Contradiction:
Improveaccess controlVSAvoidpublic sharing
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system segments URL access into two types: private URLs for authenticated email recipients and public URLs for general access. The email system generates public URLs that can be accessed by anyone without authentication, while still maintaining the ability to track access and provide selective visibility to senders through the public profile mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary public profile mechanism between the private email system and public access. The public profile acts as a mediator that receives content from private emails, rewrites URLs to public formats, and presents them in a controlled manner, allowing public sharing while maintaining the original private email structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If email systems track access to links and attachments, then analytics and engagement metrics are improved, but system complexity and implementation difficulty worsen

Engineering Contradiction:
Improveaccess trackingVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system creates a public profile that is a simplified copy or representation of the private email content. Instead of modifying the complex private email system to add tracking, the patent creates a parallel public structure that mirrors essential information (URLs, attachments, images) with built-in public access and tracking capabilities, avoiding direct modification of the private email infrastructure.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If all URLs in emails are rewritten to public short URLs, then public accessibility and tracking are improved, but processing time and system resource usage worsen

Engineering Contradiction:
Improvepublic accessibilityVSAvoidprocessing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system applies partial action by selectively rewriting only certain URLs in emails to public short URLs, rather than all URLs. This allows the system to focus processing resources on URLs that benefit from public accessibility and tracking, while leaving other URLs unchanged, thereby reducing overall processing overhead while still achieving the desired public sharing functionality for relevant content.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

This invention is an email system that replaces every URL, attachment and image in the email message with a short URL, where the original URL, attachment or image is publicly accessible through the short URL. The system further includes the short URL in the public profile associated with the email address of the sender and also publishes the most popular short URLs in the system.
