Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If highly customized data files are generated for additive manufacturing, then product customization capability is improved, but production time and computational resources increase
Solution Approach 1:
The boundary shape is subdivided into multiple work cells, allowing parallel processing and generation of customized data files for different regions simultaneously. This segmentation enables the system to handle customization requirements while reducing overall computational time by distributing the workload across multiple independent units.
Solution Approach 2:
A database of pre-characterized lattices with known mechanical properties is prepared in advance. During the customization process, these pre-characterized lattices are selected and assembled based on desired mechanical properties, eliminating the need to generate and analyze lattice configurations from scratch for each customized object, thus significantly reducing computational time.
2Adaptability or versatility
If highly customized data files are generated for additive manufacturing, then product customization capability is improved, but computational resources and cost increase
Solution Approach 1:
Lattices are pre-characterized with their mechanical properties stored in a database before the customization process. This preliminary action allows the system to simply retrieve and assemble existing lattice data rather than performing complex computational analysis for each customization request, thereby reducing computational resource requirements while maintaining high customization capability.
Solution Approach 2:
The system uses discrete lattice types with predefined mechanical properties from the database, selecting appropriate lattices by matching desired mechanical property parameters. This approach transforms the complex problem of generating customized data files into a parameter-matching and assembly task, significantly reducing computational complexity while preserving customization flexibility.
