Solution Overview

Problem

The cluttered and disorderly nature of electronic mail inboxes leads to degraded human-computer interaction (HCI) and increased resource consumption, as users struggle to manage and organize large volumes of messages effectively, with manual rule-setting providing limited and inflexible controls.

Innovation Solution

A mail handling application assigns users to distribution lists based on predefined parameters, allowing the mail server to parse and prioritize messages, and the application provides features like message conversion, escalation alerts, and automated responses to improve inbox organization and HCI.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual rule-setting is used to organize emails, then some control over message organization is achieved, but the system becomes cumbersome and tedious with limited and inflexible controls

Engineering Contradiction:
Improveease of message organizationVSAvoidcomplexity of rule setup
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system performs automatic classification of email messages using machine learning models without requiring users to manually create rules. The mail server autonomously analyzes message content, sender information, and communication patterns to categorize and route messages to appropriate folders, making the system self-organizing and eliminating the need for complex manual rule configuration

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical rule-setting operations with automated machine learning-based classification systems. Instead of users manually creating and maintaining classification rules, the system uses trained models to automatically analyze and categorize messages based on their content and metadata, substituting human cognitive effort with automated intelligent processing

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If all electronic mail messages are displayed in the inbox, then complete message access is provided, but the inbox becomes cluttered and disorderly degrading HCI quality

Engineering Contradiction:
Improvecompleteness of message accessVSAvoidquality of human-computer interaction
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The system segments the inbox by automatically classifying email messages into different categories and folders based on their content, sender, and other attributes. This segmentation organizes messages into logical groups (e.g., important, spam, newsletters, personal) while maintaining complete access to all messages through the folder structure, thus reducing clutter while preserving information completeness

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an automated classification system as an intermediary between the incoming email stream and the user inbox. This intermediary automatically filters, categorizes, and routes messages before they reach the user's view, acting as a mediator that preserves all messages while organizing them in a HCI-friendly manner through intelligent preprocessing

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of information

If users manually search through accumulated messages to find desired content, then complete message review is possible, but time consumption and resource usage increase

Engineering Contradiction:
Improvecompleteness of message retrievalVSAvoidtime to find desired messages
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary classification and organization of email messages at the time of receipt, automatically categorizing them into appropriate folders and tagging them with relevant metadata before users need to search. This advance organization eliminates the need for manual searching later, as messages are already positioned in logical locations based on their content and importance

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where the system learns from user interactions with classified messages, adjusting its classification algorithms based on user behavior patterns. This feedback loop continuously improves the accuracy of message routing and organization, making retrieval increasingly efficient while maintaining complete access to all messages through the organized structure

Inventive Principle:
Principle #23Feedback

AI summary

Presented herein are systems and methods for handling email messages. An application may identify, via the user interface, one or more properties defining a distribution list to assign a user of the client device. The application may transmit, to the server, the one or more properties to assign the user of the client device to the distribution list, with which at least one of a plurality of email messages to is selected for sending to the client device. The application may receive, from the server, an identification of a subset of email messages selected from the plurality of email messages based on an assignment of the user of the client device to the distribution list and content in the subset of email messages. The application may present, in the user interface, a message list of the subset of email messages.
