Engineering Contradiction Analysis
1Ease of manufacture
If traditional shape-describing methods (cell model, network model, diffusion model, string model) are used to represent 3D curved surfaces, then the implementation is simple, but the precision of representing complex curved-surface shapes deteriorates
Solution Approach 1:
The patent transitions from representing 3D curved surfaces directly to representing 2D cross-sectional shapes that can be precisely defined by boundary lines. By changing the dimensionality of the representation approach (from 3D surface mesh to 2D cross-section with boundary), the patent achieves high precision in representing complex curved surfaces while maintaining implementation simplicity through standard solid modeling techniques.
2Ease of manufacture
If rectangular cross-sectional surfaces are used in solid modeling, then the implementation is straightforward, but the ability to reproduce detailed and complex curved-surface shapes deteriorates
Solution Approach 1:
The patent segments the 3D curved surface representation into multiple 2D cross-sectional shapes. Each cross-section is defined by precise boundary lines that can capture complex curved geometries. By dividing the 3D representation problem into 2D cross-sectional segments, the patent maintains implementation straightforwardness while achieving detailed curved-surface reproduction capability.
3Manufacturing precision
If high precision 3D curved surface representation is achieved using traditional models, then shape accuracy is improved, but calculation time increases
Solution Approach 1:
The patent uses 2D cross-sectional boundary line representations that can be efficiently copied and processed. Instead of dealing with complex 3D surface meshes that require extensive calculation, the patent represents curved surfaces through 2D cross-sections with boundary lines, which can be processed more quickly while maintaining shape accuracy. This copying approach reduces computational complexity significantly.
