Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If real-time rendering of 3D models is used, then interactive avatars can be generated, but the computational intensity is extremely high and delivery of high-definition output is difficult
Solution Approach 1:
The patent pre-computes and stores animation frames in advance before they are needed for real-time avatar generation. By preparing the animation sequences beforehand and storing them in a database, the system avoids performing computationally intensive rendering operations during real-time interaction, thus resolving the contradiction between generation speed and output quality.
2Manufacturing precision
If manual animation by animators is used, then precise control over animation is achieved, but the process is extremely labor-intensive and time-consuming
Solution Approach 1:
The patent uses motion capture technology to record real human movements and creates digital copies of these movements that can be applied to avatar models. This copying approach maintains the precision of human animation while dramatically reducing the labor intensity and time required, as the movements are captured automatically rather than manually crafted frame-by-frame.
Solution Approach 2:
The patent replaces the manual mechanical process of frame-by-frame animation with automated motion capture systems and computer-generated interpolation algorithms. This substitution eliminates the need for animators to manually position each frame while still achieving smooth, precise animation through automated computational methods.
3Manufacturing precision
If motion capture technique is used, then high realistic and lifelike animations are produced, but extensive and expensive equipment is required making it inaccessible
Solution Approach 1:
The patent develops a motion capture system that can serve multiple functions: capturing realistic human movements, storing the data in standardized formats, and applying the captured movements to various avatar models. This multi-functional approach reduces the need for specialized equipment for each specific animation task, making the system more accessible and cost-effective while maintaining high realism.
4Extent of automation
If procedural techniques are used, then automation is improved, but the animations become more generic and less personalized
Solution Approach 1:
The patent applies different quality levels to different parts of the animation system: procedural techniques are used for general body movements where automation is sufficient, while motion capture data is used for facial expressions and distinctive movements where personalization is critical. This localized application of different techniques maintains automation benefits while preserving personalization where it matters most.
