Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors and location trackers are integrated with 3D reconstruction algorithms to associate sensed conditions with spatial positions, then measurement precision and control precision are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple previously separate functions into an integrated system: sensors for detecting body conditions, location trackers for spatial positioning, and 3D reconstruction algorithms for virtual environment mapping. This merging enables precise association of sensed conditions with spatial positions while managing system complexity through unified architecture.
Solution Approach 2:
The system transitions from traditional 2D display interfaces to a full 3D virtual environment representation of the user's body. By reconstructing the body model in three-dimensional space and mapping sensor data to corresponding 3D coordinates, the system achieves precise spatial localization and enables intuitive interaction from multiple viewing angles.
2Loss of information
If a virtual three-dimensional environment is created for reconstructing sensed conditions, then information completeness is improved, but loss of time for processing increases
Solution Approach 1:
The system pre-establishes a 3D virtual model of the user's body geometry and topology before sensing begins. This preliminary preparation allows sensor data to be directly mapped to pre-defined spatial coordinates and surface regions, eliminating the need for complex real-time 3D reconstruction and reducing processing time during actual sensing operations.
Solution Approach 2:
The system creates a virtual copy or digital twin of the user's body in three-dimensional space, which serves as a reference framework for mapping sensor measurements. This virtual model preserves complete geometric and topological information, enabling comprehensive data association without requiring repeated physical scanning or complex calculations during measurement.
