Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional character customization systems are used, then character creation is possible, but the process is tedious and time-consuming

Engineering Contradiction:
Improvecharacter creation speedVSAvoidtime required for character customization
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system captures the user's actual movements through video analysis and creates animations by copying these movements directly to the character. This eliminates the need for manual animation selection or configuration, allowing characters to be created quickly while maintaining personalized movement characteristics.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system automatically analyzes user movements and generates character animations without requiring manual input or configuration. The character creation process serves itself by using the user's natural movements as the source material, eliminating tedious setup steps and reducing time investment.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If detailed character customization is provided, then character personalization is improved, but the complexity of the system increases

Engineering Contradiction:
Improvecharacter personalizationVSAvoidcustomization system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system replaces complex manual customization interfaces with automated video analysis and AI-driven character generation. Instead of requiring users to navigate through multiple menus and parameters, the system automatically extracts movement characteristics from video input and generates personalized characters, reducing interface complexity while maintaining personalization.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the fundamental parameters of character creation by using video-based movement capture instead of traditional manual input methods. This paradigm shift allows for detailed personalization through natural movement patterns while keeping the user interface simple and intuitive.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If manual animation configuration is required, then animation precision is improved, but the ease of operation decreases

Engineering Contradiction:
Improveanimation accuracyVSAvoidcharacter creation ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The system copies the user's actual movements directly to the character animations, ensuring high accuracy in movement representation. This direct copying approach maintains animation precision while eliminating the need for manual configuration, as the movements are captured authentically from the user's own performance.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The animation system performs self-configuration by automatically analyzing video input and generating appropriate animations without user intervention. This maintains operational simplicity while achieving precise animations through automated movement recognition and mapping algorithms.

Inventive Principle:
Principle #25Self-service

AI summary

A method for generating a character for use in a video game is provided, including: receiving captured video of a user; analyzing the captured video to identify movements of the user; using the identified movements of the user to define one or more animations of a character; receiving descriptive input generated by the user; determining game-specific constraints for the character in the video game; using the descriptive input and the game-specific constraints to prompt a generative artificial intelligence (AI) to generate visual elements of the character; using the character for gameplay of a video game, wherein using the character includes rendering the character having the generated visual elements and triggering the animations during the gameplay.
