Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If virtual anatomical data is aligned with medical image data using anatomical landmarks, then positional correspondence is achieved, but the detail and resolution of anatomical structures are insufficient for precise simulations
Solution Approach 1:
The patent segments the human body model into a three-dimensional voxel grid system, dividing the continuous anatomical space into discrete volumetric elements. This segmentation enables precise representation of anatomical structures at the voxel level while maintaining overall positional alignment with medical image data, resolving the contradiction between positional correspondence and structural detail.
2Manufacturing precision
If detailed anatomical structures are represented with high-resolution voxels, then simulation precision is improved, but data processing complexity and computational load increase
Solution Approach 1:
The patent applies local quality by assigning different voxel sizes to different anatomical regions based on their specific requirements. Critical areas requiring high precision (e.g., tumor regions, surgical sites) use smaller voxels for detailed representation, while less critical areas use larger voxels to reduce overall data complexity. This resolves the contradiction between simulation precision and processing complexity through spatially adaptive resolution.
3Ease of operation
If uniform voxel sizing is used throughout the body model, then data processing is simplified, but resolution and accuracy vary inadequately across different anatomical regions
Solution Approach 1:
The patent implements dynamic voxel sizing where the voxel dimensions are adjusted according to the specific anatomical region and its requirements for simulation accuracy. The system dynamically selects appropriate voxel sizes based on local anatomical features, allowing fine detail in critical regions while maintaining coarser resolution elsewhere, thus balancing processing simplicity with anatomical precision.
