Solution Overview

Problem

Existing electronic communication systems, such as email and instant messaging, lack efficient methods for responding to or forwarding specific portions of messages and maintaining logical context, especially in multi-level conversations or when participants join mid-conversation.

Innovation Solution

A distributed computer system with conversation servers and clients that manage and render electronic messages, allowing for real-time updates, concurrency control, and playback of edits, ensuring that all participants have access to the full conversation context across various devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple participants edit conversation content simultaneously from different devices, then real-time collaboration and accessibility are improved, but conflicts arise between competing edits

Engineering Contradiction:
Improvereal-time collaboration efficiencyVSAvoidedit consistency
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system implements a feedback mechanism where the server monitors edit operations from multiple participants, detects conflicts between competing edits, and provides feedback by selecting which edits to apply. The server compares timestamped edit requests, identifies conflicts when edits target the same content unit, and resolves them by applying non-conflicting edits while rejecting conflicting ones, ensuring consistent state across all participants' devices.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The server acts as an intermediary between multiple participants' devices. It receives edit requests from different participants, mediates conflicts by comparing timestamps and determining which edits to apply, and ensures all participants receive a consistent version of the conversation content. This intermediary role prevents direct conflicts between participants' devices while maintaining real-time collaboration.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the system tracks and resolves all edit conflicts in real-time, then edit consistency is maintained, but system complexity and processing overhead increase

Engineering Contradiction:
Improveedit consistencyVSAvoidserver processing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by assigning unique timestamps to each edit request before conflicts occur. This timestamping mechanism is established in advance, allowing the server to efficiently determine edit order and detect conflicts without complex real-time analysis. The preliminary timestamp assignment simplifies the conflict resolution process by providing a clear chronological framework.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system segments the conversation into discrete content units, each with its own edit history and timestamp. This segmentation allows the server to track and resolve conflicts independently for each content unit rather than analyzing the entire conversation as a single complex entity. Each content unit can be edited and conflicted upon separately, reducing overall system complexity.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the system allows free editing of conversation content, then user flexibility and ease of operation are improved, but logical context and message structure may be lost

Engineering Contradiction:
Improveediting flexibilityVSAvoidlogical context
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The conversation is segmented into discrete content units that maintain their individual identities and positions within the overall conversation structure. Each content unit can be independently edited while preserving its place in the logical flow. This segmentation allows flexible editing of specific portions without disrupting the broader conversational context and logical structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system establishes a preliminary structure by organizing conversation content into fixed positional slots and content units before editing occurs. This pre-established framework ensures that even as content is freely edited, the logical context and structural relationships between messages are preserved through the maintained positioning and hierarchical organization of content units.

Inventive Principle:
Principle #10Preliminary action

AI summary

A server system hosts a plurality of conversations. For a respective conversation the server system receives a first sequence of edits and a second sequence of edits to a respective content unit of the conversation from different participants of the conversation. The server system converts the first and second sequences of edits into respective first and second merged sequences of edits. The server system responds to a determination that the first merged sequence of edits and the second merged sequence of edits meet predefined conflict criteria by transforming the first and second merged sequences of edits. The server system sends the respective transformed sequences of edits to respective participants so that respective participants can apply either the first sequence of edits followed by the second transformed sequence of edits or applying the second sequence of edits followed by the first transformed sequence of edits to produce a same result.
