Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional 3D computer graphics method is used to generate virtual environments, then the graphic quality and realism can be achieved, but the cost and effort increase significantly when changing graphic styles due to required 3D modeling recreation

Engineering Contradiction:

ImproveAbility to provide varied virtual environments with different graphic stylesVSAvoidCost and effort of recreating 3D models when changing graphic styles

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent uses video content as a copy or reference source to generate virtual environments. Instead of creating original 3D models from scratch for each graphic style, the system extracts motion data from video content and uses it to generate virtual content that replicates the visual appearance and motion characteristics of the source video, thereby reducing the need for repeated 3D modeling work

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system changes parameters such as graphic style, resolution, and motion extraction levels to adapt the virtual environment generation process to different requirements. By adjusting these parameters, the same underlying technology can produce varied virtual environments with different graphic styles without requiring complete recreation of 3D models

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If detailed motion data extraction is performed to ensure accurate virtual content generation, then the fidelity of virtual content improves, but the processing time and computational resources increase

Engineering Contradiction:

ImproveFidelity of extracted motion data for virtual content generationVSAvoidProcessing time for motion data extraction

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies partial action by extracting only the necessary motion data required for virtual content generation rather than processing all possible motion parameters. The system determines appropriate extraction levels based on the specific virtual environment requirements, avoiding unnecessary processing of excessive motion data and thereby reducing processing time while maintaining sufficient fidelity

Inventive Principle:

Principle #16Partial or excessive action
