Solution Overview

Problem

Existing messaging systems lack efficient automated methods for generating and managing distribution lists, leading to inefficiencies in message forwarding and security concerns such as spamming.

Innovation Solution

A system and method for automatically generating distribution lists based on specific identifiers, where a processor in a server generates a distribution list upon receiving a message with a given identifier, and only forwards messages to network addresses associated with the list when received from authorized sources, incorporating security features like domain part restrictions and keyword authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual distribution list management is used, then security control is maintained, but message delivery efficiency deteriorates

Engineering Contradiction:
Improvemessage delivery efficiencyVSAvoiddistribution list management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system enables automatic distribution list generation where the messaging server itself creates and manages distribution lists based on message content analysis, eliminating the need for manual administrative intervention while maintaining security through automated authorization mechanisms

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-processes message content to identify distribution list identifiers before message delivery, allowing the server to automatically generate and prepare distribution lists in advance, thereby improving message delivery efficiency without increasing operational complexity

Inventive Principle:
Principle #10Preliminary action

2Productivity

If automated distribution list generation is implemented, then message delivery efficiency improves, but security risks increase

Engineering Contradiction:
Improvemessage delivery efficiencyVSAvoidspamming and security risks
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system incorporates feedback mechanisms where the messaging server analyzes message content, identifies distribution list identifiers, and automatically generates lists while monitoring for spam patterns, allowing real-time security adjustments based on message characteristics

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system introduces an intermediary authorization mechanism between message sending and distribution list generation, where the messaging server acts as a mediator that validates message content, identifies appropriate distribution lists, and controls the forwarding process to prevent spamming while maintaining efficiency

Inventive Principle:
Principle #24Intermediary (Mediator)

3Speed

If distribution lists are created without authorization checks, then message forwarding speed increases, but harmful factors increase

Engineering Contradiction:
Improvemessage forwarding speedVSAvoidspamming
Core Design Contradiction:
SpeedVSObject-generated harmful factors

Solution Approach 1:

The system performs authorization checks and distribution list generation in advance before message forwarding, pre-validating message content and identifying authorized distribution lists, thereby maintaining fast message delivery while preventing spamming through preliminary security measures

Inventive Principle:
Principle #10Preliminary action
