Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional motion capture systems with multiple cameras and markers are used, then motion tracking accuracy is improved, but system complexity and cost increase significantly
Solution Approach 1:
The patent extracts and eliminates the complex infrastructure of multiple synchronized cameras and physical markers from the motion capture system. Instead, it uses only a single camera combined with computer vision algorithms to detect and track motion, thereby maintaining measurement precision while dramatically reducing system complexity and cost.
Solution Approach 2:
The patent creates a virtual model (digital twin) of the physical environment and characters. This virtual copy allows the system to track motion by comparing real-time camera images against the pre-scan virtual model, enabling accurate motion capture without requiring multiple physical cameras or markers.
2Shape
If detailed character models with many polygons are used, then visual realism is improved, but processing time and computational resources increase
Solution Approach 1:
The patent implements dynamic level-of-detail (LOD) technology that automatically adjusts the polygon count and model complexity based on the character's distance from the camera and current action intensity. When a character is far away or performing simple actions, the model uses fewer polygons; when close or performing complex actions, the model increases detail. This dynamic adaptation maintains visual realism while significantly reducing processing time and computational resource requirements.
3Speed
If real-time rendering with high frame rates is achieved, then interaction responsiveness is improved, but computational load and energy consumption increase
Solution Approach 1:
The patent implements frame rate adaptation that dynamically adjusts rendering frequency based on scene complexity and character distance. When characters are far away or the scene is simple, the frame rate is reduced; when characters are close or scene complexity increases, the frame rate increases to maintain responsiveness. This periodic adjustment maintains interaction responsiveness while significantly reducing computational energy consumption during less critical moments.

AI summary
A system for controlling costumed character interaction includes a character costume configured to be worn by a user. The character costume includes an electromagnet integrated into the character costume. The system also includes a stage prop including a magnetic piece integrated into the stage prop. The system further includes a control interface coupled to the electromagnet. The control interface is configured, via a control signal, to activate and to deactivate the electromagnet to control interaction between the character costume and the stage prop via magnetic interaction between the electromagnet and the magnetic piece.
