Solution Overview

Problem

Conventional electronic messaging systems fail to effectively re-engage participants in group messaging threads after a period of absence, as they are overwhelmed by a large number of missed messages, leading to disengagement due to the time-consuming process of catching up.

Innovation Solution

An electronic messaging system that determines a participant's absence and identifies 'highlight' messages likely to be of interest, such as those with media, hyperlinks, or mentions, scoring and providing these messages upon re-access, allowing participants to quickly catch up and re-engage with the thread.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a participant returns to a group messaging thread after a period of absence, then they can access the full conversation history, but they are overwhelmed by the large number of messages and spend excessive time catching up

Engineering Contradiction:
Improveconversation contextVSAvoidtime to catch up
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system extracts and identifies key messages from the conversation thread that are most relevant to the returning participant. These highlighted messages are presented separately from the full message stream, allowing the participant to quickly grasp essential conversation context without being overwhelmed by all messages.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The message stream is segmented into highlighted key messages and regular messages. The highlighted messages are presented in a condensed format (such as a summary view or sidebar), while the full message stream remains accessible but separate, enabling participants to navigate efficiently based on their needs.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If all messages are displayed chronologically, then the complete conversation history is preserved, but the interface becomes complex and difficult to navigate for absent participants

Engineering Contradiction:
Improveconversation historyVSAvoidthread navigation
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The interface dynamically adapts based on the participant's absence duration and engagement patterns. For participants returning after long absences, the system provides a condensed highlighted message view. As participants engage more, the system gradually introduces additional context and full message visibility, creating a dynamic navigation experience that evolves with user needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system adds a new dimension to message presentation by displaying highlighted messages in a separate spatial dimension (such as a sidebar, overlay, or summary panel) rather than mixing them linearly with the full message stream. This allows participants to access key information without navigating through the entire chronological sequence.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Loss of information

If the system provides all missed messages immediately, then complete information is available, but the participant becomes disengaged due to the overwhelming volume of content

Engineering Contradiction:
Improvemissed messagesVSAvoidre-engagement speed
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The system performs preliminary action by pre-processing and highlighting key messages before the participant returns. This preparation work is done in advance, organizing and tagging important messages based on conversation analysis, so that when the participant returns, the essential information is already prepared and easily accessible without requiring them to process all messages.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system enables participants to skip through non-essential content by providing a condensed view of highlighted messages. Participants can rapidly scan and selectively engage with important messages while automatically or manually skipping over less relevant content, accelerating their re-engagement process.

Inventive Principle:
Principle #21Skipping (Rushing through)

AI summary

The present disclosure is directed to systems and methods for identifying and providing highlight messages from a group messaging thread. For example, systems and methods described herein detect when a group messaging thread participant becomes absent from the group messaging thread, and identifies one or more highlight messages that were submitted to the group messaging thread while the participant was absent. Systems and methods described herein identify highlight messages that are specific to the absent participant, such that when the participant again accesses the group messaging thread, the participant can review the identified highlight messages in order to quickly “catch up” on the group messaging thread without having to read each electronic message submitted to the group messaging thread during the participant's absence.
