Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing instant messenger systems lack the ability to provide real-time information on member activity peaks and hot messages within chatrooms, making it difficult for users to understand conversation flow and participate effectively.

Innovation Solution

A computer device and method that displays activity time information, including member activity peaks and hot messages, on a chatroom screen, using a processor to analyze member activity patterns and provide a timeline and highlight information based on user requests.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If users directly participate in chatroom conversations to understand conversation flow, then they can grasp the context and key messages, but it consumes excessive time and resources

Engineering Contradiction:

Improveconversation flow understandingVSAvoidtime for direct participation

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent introduces an intermediary system that automatically analyzes chatroom conversations and generates activity time information including peak activity periods and hot messages. This intermediary processing allows users to understand conversation flow without directly participating in every message exchange, thereby resolving the contradiction between information understanding and time consumption

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If the system provides detailed activity time information and hot messages, then users can understand conversation flow better, but the system complexity increases

Engineering Contradiction:

Improveconversation flow informationVSAvoidsystem processing complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent extracts only the most essential information from chatroom conversations - specifically peak activity time periods and hot messages - rather than processing and presenting all conversation data. This selective extraction approach provides sufficient conversation flow information while maintaining relatively simple system complexity

Inventive Principle:

Principle #2Taking out (Extraction)

3Measurement precision

If the system analyzes member activity patterns to provide activity time information, then the information accuracy improves, but the processing time and computational resources increase

Engineering Contradiction:

Improveactivity time information accuracyVSAvoidcomputational resource consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent changes the parameters being measured to focus only on key indicators such as message sending frequency, peak activity periods, and hot message identification. By transforming the analysis parameters to these essential metrics rather than comprehensive conversation analysis, the system achieves accurate activity time information with reduced computational resource consumption

Inventive Principle:

Principle #35Parameter changes

AI summary

Disclosed are a method, a computer device, and a non-transitory computer-readable record medium to display activity time information of a chatroom. An activity time information display method may include receiving a user request for activity time information of a chatroom related to an instant messenger from a user of the computer device for the chatroom related to the instant messenger and displaying the activity time information of the chatroom on a chatroom-related screen of the chatroom in response to the user request.
