Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additive manufacturing is used to produce components, then manufacturing flexibility and complexity handling are improved, but anisotropic material properties and insufficient strength occur
Solution Approach 1:
The patent applies preliminary action by determining the optimal build orientation before the actual additive manufacturing process. The method calculates preferred orientations based on directional dependency data and component geometry, then uses this pre-determined orientation information to guide the manufacturing process, ensuring that strength requirements are met before production begins
Solution Approach 2:
The patent changes the build orientation parameter to optimize component strength. By varying the orientation angle and direction of the build process based on calculated preferred orientations, the method adjusts material properties and structural characteristics to achieve required strength levels while maintaining additive manufacturing flexibility
2Strength
If build orientation is optimized for strength, then component strength is improved, but manufacturing process complexity increases
Solution Approach 1:
The patent applies self-service by implementing an automated computational system that determines optimal build orientations without requiring manual expert intervention. The method uses algorithms to automatically calculate preferred orientations based on input parameters, eliminating the need for complex manual analysis and making the optimization process self-executing
Solution Approach 2:
The patent replaces manual mechanical orientation determination with a computational system. Instead of relying on expert judgment and manual analysis, the method uses computer-based calculations and algorithms to determine optimal build orientations, substituting mechanical/expert processes with automated computational processes
3Measurement precision
If directional dependency is examined using numerical simulation, then accuracy of orientation determination is improved, but computational time and resources increase
Solution Approach 1:
The patent applies partial action by using simplified directional dependency data and approximate calculation methods rather than full-scale complex numerical simulations. The method determines preferred orientations using reduced computational models that provide sufficient accuracy for manufacturing purposes without requiring exhaustive computational resources
