Engineering Contradiction Analysis
1Manufacturing precision
If existing methods are used to design 3D modeled objects with anisotropic materials, then the design process can be completed, but the accuracy and industrial feasibility of the designs deteriorate
Solution Approach 1:
The patent changes the parameter of material orientation from arbitrary to optimized alignment with dominant force directions. By adjusting the orientation field parameters to match the physical property directions with the applied forces, the design achieves both accuracy and industrial feasibility, resolving the contradiction between design quality and manufacturability
Solution Approach 2:
The patent applies local quality optimization by aligning material orientations specifically with the dominant force directions at different locations of the mechanical part. This localized alignment ensures that each region's material properties are optimized for its specific loading conditions, improving both design accuracy and industrial feasibility simultaneously
2Strength
If material orientation is optimized to align with force directions, then mechanical performance improves, but design complexity increases
Solution Approach 1:
The patent replaces complex manual orientation design processes with an automated computer-implemented optimization method. The system automatically determines optimal orientation fields based on the finite element mesh and applied forces, substituting mechanical/design complexity with computational algorithms that efficiently produce optimized results without increasing practical design complexity
Solution Approach 2:
The optimization method is self-service in nature, automatically determining the optimal material orientations based on the input forces and geometry without requiring extensive manual intervention. The system serves itself by computing the orientation field that maximizes mechanical performance given the loading conditions, reducing the burden on designers while maintaining high performance

AI summary
The invention notably relates to a computer-implemented method for designing a 3D modeled object. The 3D modeled object represents a mechanical part formed in a material having an anisotropic behavior with respect to a physical property. The method comprises providing a 3D finite element mesh and data associated to the 3D finite element mesh. The data associated to the 3D finite element mesh includes a plurality of forces and boundary conditions. The plurality of forces forms multiple load cases. The method further comprises optimizing an orientation field distributed on the 3D finite element mesh with respect to an objective function. The objective function rewards orientation continuity with respect to the physical property. The optimizing is based on the 3D finite element mesh and on the data associated to the 3D finite element mesh. This constitutes an improved method for designing a 3D modeled object.
