Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing techniques for generating and sending emojis and virtual avatars are used, then emojis and virtual avatars can be sent as part of messaging communications, but the process is cumbersome and inefficient, requiring multiple key presses or keystrokes

Engineering Contradiction:

Improveease of generating and sending emojisVSAvoidtime required for generating and sending emojis

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system automatically captures facial expressions via the camera and generates corresponding virtual avatars without requiring manual selection or multiple key presses. The user simply positions their face in the camera view, and the system self-services by detecting the expression, generating the avatar, and preparing it for sending, thereby dramatically reducing both time and operational complexity

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical interaction of multiple key presses and manual avatar selection with an automated optical and computational system. The camera captures facial expressions, and software algorithms automatically generate and animate virtual avatars, substituting manual mechanical operations with automated sensing and processing

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If existing techniques for generating and sending emojis and virtual avatars are used, then emojis and virtual avatars can be sent as part of messaging communications, but the process wastes user time and device energy, particularly in battery-operated devices

Engineering Contradiction:

Improveefficiency of generating and sending emojisVSAvoiddevice energy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The system uses periodic action by capturing facial expressions at specific intervals or triggered by user input rather than continuously processing. The camera and processing system activate only when needed (e.g., when the user opens the emoji picker or holds the camera steady), reducing unnecessary energy consumption while maintaining high productivity when active

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The automated system performs all generation and animation tasks without requiring repeated user commands, completing the emoji creation process in a single continuous operation rather than through multiple discrete steps. This self-service approach reduces both the time the system remains active and the total energy consumed

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If existing techniques for generating and sending emojis and virtual avatars are used, then emojis and virtual avatars can be sent as part of messaging communications, but the user interface is complex and time-consuming

Engineering Contradiction:

Improvecapability to generate static and animated avatarsVSAvoidcomplexity of user interface

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system provides multi-functionality by enabling the generation of both static and animated virtual avatars through a single unified interface. The same camera-based facial expression capture works for both avatar types, with the animation feature automatically enabled when appropriate, eliminating the need for separate interfaces or complex configuration options

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically determines whether to generate a static or animated avatar based on the captured facial expression and context, without requiring the user to manually select the avatar type. The system self-services by analyzing the expression data and selecting the appropriate output format, thereby simplifying the interface while maintaining versatility

Inventive Principle:

Principle #25Self-service

AI summary

The present disclosure generally relates to generating and modifying virtual avatars. An electronic device having a camera and a display apparatus displays a virtual avatar that changes appearance in response to changes in a face in a field of view of the camera. In response to detecting changes in one or more physical features of the face in the field of view of the camera, the electronic device modifies one or more features of the virtual avatar.
