Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If markers and multiple cameras are used to detect user motion, then motion detection precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts the motion detection function from complex external systems (markers and multiple cameras) and concentrates it into a single wearable sensor device attached to the user's body, thereby maintaining measurement precision while dramatically reducing device complexity
Solution Approach 2:
The wearable sensor device serves multiple functions: it detects motion in three-dimensional space, tracks user position, and provides input signals for various applications (games, training, navigation), replacing the need for separate markers and cameras while maintaining detection precision
2Measurement precision
If multiple cameras and markers are prepared for motion detection, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The sensor device is self-contained and automatically detects user motion without requiring the user to manually position markers or configure camera systems, making the system easy to operate while maintaining precise motion detection through its autonomous sensing capabilities
3Ease of operation
If a controller operated by hand is used, then ease of operation is maintained, but adaptability to different input methods deteriorates
Solution Approach 1:
The wearable sensor system provides a universal input method that can be used across various applications (games, training programs, navigation) and can detect different types of user actions (walking, running, jumping, gesturing), thereby maintaining ease of operation while significantly improving adaptability to different input methods
