Solution Overview

Problem

Existing instant messaging services lack a function to reject group chat room invitations, leading to unintended participation by users.

Innovation Solution

A method and apparatus for a messenger service that allows users to decide whether to participate in a group chat room by displaying information on the inviter and an interface for decision-making, and enabling users to exit the group chat room if they choose to participate unintentionally.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the messenger service automatically adds users to group chat rooms without requiring their consent, then the group chat room can be formed quickly and efficiently, but users may participate unintentionally against their will

Engineering Contradiction:

Improvegroup chat room formation speedVSAvoiduser participation control

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system performs preliminary action by automatically adding users to the group chat room list before final participation. The server prepares the group chat room and sends invitation information to potential members, but the actual participation requires user confirmation through the interface, thus preventing unintended participation while maintaining efficient group formation

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by providing users with an interface to confirm or reject group chat room invitations. The user terminal displays chat room information and seeks user input regarding participation, allowing users to control their involvement based on their actual intention, thereby resolving the contradiction between automatic formation and user control

Inventive Principle:

Principle #23Feedback

2Loss of information

If the system displays all chat room information including messages from users not registered as friends, then users can see complete chat room content, but it may reveal information to users who should not have access

Engineering Contradiction:

Improvechat room information accessibilityVSAvoidinformation leakage to unauthorized users

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The system applies local quality by differentiating the display of chat room information based on user relationships. When a user is not registered as a friend of the inviter, the interface displays limited information (invitation indicator, inviter information) rather than complete message history, thus preventing information leakage to unauthorized users while maintaining accessibility for friends

Inventive Principle:

Principle #3Local quality

AI summary

A method for a first user terminal to use a messenger service of a group chat room is proposed. The method may include receiving, from a server, invitation information associated with a second user's inviting a first user to the group chat room, and displaying chat room information on the group chat room. The method may also include in response to the second user not being registered as a friend of the first user in the messenger service, displaying information on the second user and an interface for deciding whether to participate in the group chat room. The method may further include acquiring an interaction regarding a decision to participate in the group chat room through the interface, and displaying a message created in the group chat room.
