Solution Overview

Problem

Existing emoticon systems in chat rooms are inconvenient for users as they are listed in a simple list form, requiring users to scroll and select pages, making it difficult to find emoticons expressing specific looks or feelings.

Innovation Solution

A method and server system that provides a content list to users, allowing them to easily access and use emoticons used by their chatting counterparts in chat rooms. This system includes operations for providing source content, receiving requests for content lists, selecting keyword-related and group-related content, and providing selected content back to the chat room.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If emoticons are listed in a simple list form, then the system structure is simple, but user convenience deteriorates as users have to scroll and select pages to find specific emoticons

Engineering Contradiction:
Improveease of emoticon selectionVSAvoidcomplexity of content list system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The content list is segmented into multiple categories (e.g., 'All', 'Recent', 'Favorites', 'Recommended') that can be switched between. This segmentation allows users to access different subsets of emoticons based on their needs, reducing the need to scroll through the entire list and improving selection efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A search function is introduced as an intermediary tool between the user and the emoticon list. Users can input keywords to directly locate specific emoticons, eliminating the need to manually scroll through pages. This intermediary mechanism resolves the contradiction by providing direct access without increasing the fundamental list structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If emoticons are listed by characters only, then the listing method is simple, but user convenience deteriorates as it becomes difficult to find emoticons expressing specific looks or feelings

Engineering Contradiction:
Improveease of finding specific emoticonsVSAvoidloss of contextual information about emoticons
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

Different parts of the emoticon display are given different qualities: the emoticon image itself, its name, category tags, and usage context are all displayed with distinct visual characteristics. This allows users to quickly scan and identify emoticons based on multiple attributes simultaneously, improving search efficiency without losing important information.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system adds multiple dimensions to the emoticon listing beyond just character names. Emoticons are organized and displayed with additional dimensions such as category tags, usage frequency, and contextual metadata. This multi-dimensional organization allows users to find emoticons expressing specific looks or feelings by filtering across multiple attributes rather than just searching through character names.

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

AI summary

Provided are a method and server for providing a content list. The method and server for providing a content list includes: providing source content to a chat room, receiving a request for providing a content list related to the source content from a first terminal of a first member; providing at least one of a first content list including at least one keyword-related content selected from among the entire contents stored in the server based on a keyword of the source content and a second content list including at least one group-related content belonging to the same group as a group of the source content among the entire contents, receiving information on selection content selected by the first member among the contents included in the at least one content list, from the first terminal, and providing the selection content to the chat room.
