Solution Overview

Problem

Existing messaging services lack an efficient method to integrate assistant functions, such as scheduling and search, within a limited display space of portable terminals, thereby limiting user convenience.

Innovation Solution

The implementation of an operating method on a terminal with a messaging service application that switches between chat and assistant modes within the chat interface, allowing users to access assistant functions like search, scheduling, and to-do management through a partial area of the chat interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If assistant functions are integrated into the messaging service, then user convenience is improved, but device complexity increases

Engineering Contradiction:
Improveuser convenienceVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the assistant function interface with the existing chat interface by displaying the assistant interface within the partial area of the chat interface. This integration allows users to access assistant functions (search, scheduling, to-do management) directly within the messaging application without needing to switch to separate applications, thereby improving user convenience while managing system complexity through unified interface design.

Inventive Principle:
Principle #5Merging (Combining)

2Area of stationary object

If assistant interface is displayed through partial area of chat interface, then display space utilization is improved, but interface complexity increases

Engineering Contradiction:
Improvedisplay space utilizationVSAvoidinterface complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent segments the display area into different functional zones: the chat interface occupies the full screen while the assistant interface is displayed in a partial area (e.g., overlay or sidebar). This segmentation allows efficient utilization of display space by enabling simultaneous access to both messaging and assistant functions without requiring full-screen transitions, thereby optimizing display space utilization while managing interface complexity through structured layout design.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If mode switching between chat and assistant is implemented, then functional versatility is improved, but operation complexity increases

Engineering Contradiction:
Improvefunctional versatilityVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements dynamic mode switching between chat mode and assistant mode within the unified interface. The interface can transition between displaying chat messages and displaying assistant functions (search, scheduling, to-do management) based on user interaction. This dynamic behavior provides functional versatility by allowing users to access different modes as needed, while the automated switching mechanism and contextual awareness help manage operation complexity by reducing manual configuration requirements.

Inventive Principle:
Principle #15Dynamics

AI summary

A method and apparatus for a messaging service are provided. An operating method of a terminal on which an application for a messaging service is installed includes switching an input mode of a chat interface to an assistant mode to call an assistant function, receiving a call for the assistant function, and displaying an assistant interface corresponding to the called assistant function.
