Email Attachment Caching for Reducing Redundant Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face inefficiencies in processing and delivering email attachments to multiple recipients, leading to redundant processing and resource utilization, particularly when handling HTML-based email messages with linked content items.
Innovation Solution
Implementing a wireless connector system that caches processed attachments with unique identifiers, allowing for reuse across multiple recipients without re-retrieval or re-processing, thereby reducing redundant processing and optimizing resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content items are processed and transmitted to multiple recipients individually, then each recipient receives properly formatted attachments, but the system performs redundant processing and consumes excessive resources
Solution Approach 1:
The system processes content items in advance before distribution to multiple recipients. The email service processes the first content item to create a first attachment, then stores it in an attachment cache. When subsequent recipients request the same content item, the pre-processed attachment is retrieved from cache rather than re-processing, thus maintaining delivery quality while improving efficiency.
Solution Approach 2:
The system creates cached copies of processed attachments for reuse. Instead of re-processing the same content item for each recipient, the system copies the already-processed attachment from the source into an attachment cache, allowing multiple recipients to receive identical attachments without repeating the processing steps.
2Manufacturing precision
If content items are re-processed for each recipient, then processing is thorough and consistent, but resource utilization increases and time is wasted
Solution Approach 1:
The system performs the processing action in advance for the first recipient and caches the result. Subsequent recipients receive the pre-processed attachment from cache, eliminating repeated processing while maintaining consistency since the same processing logic is applied to create the cached version.
Solution Approach 2:
The system copies the processed attachment to a cache for efficient retrieval. This copying mechanism preserves processing consistency by using the same source content item for the cached copy, while dramatically reducing processing time for subsequent recipients who receive the copied attachment without re-processing.
3Productivity
If the system caches attachments with unique identifiers, then retrieval is faster and resource usage is reduced, but system complexity increases
Solution Approach 1:
The system introduces an attachment cache as an intermediary component between the content item source and recipients. This cache stores processed attachments with unique identifiers and handles retrieval requests, speeding up access while isolating the complexity of cache management from both the source system and recipient systems.
Solution Approach 2:
The attachment cache serves multiple functions: storing processed attachments, caching unique identifiers for matching, and providing fast retrieval for multiple recipients. This multi-functional component consolidates what would otherwise require separate processing and storage mechanisms for each recipient.

AI summary
A method, server and system for the delivery of email messages with repetitive attachments. In one example embodiment, the method comprises determining a unique identifier for a content item that is referenced in an email message; determining, in dependence on the unique identifier, if an attachment corresponding to the content item is present in an attachment cache, and if a corresponding attachment is not present in the attachment cache then processing the content item to create the attachment and storing the attachment in the attachment cache identified by the unique identifier, and if the corresponding attachment is present in the attachment cache, then retrieving the corresponding attachment from the attachment cache; and sending the corresponding attachment to the mobile communications device.
