Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional additive fabrication techniques are used with fixed orientation and parameter settings, then the fabrication process is simple and fast, but the surface finish and mechanical strength are suboptimal
Solution Approach 1:
The system performs preliminary simulation of different orientations and parameter sets before actual fabrication to determine the optimal configuration. This advance planning allows selection of parameters that maximize surface finish and mechanical strength without adding complexity to the fabrication process itself.
Solution Approach 2:
The system creates virtual copies of the object in different orientations and simulates fabrication for each copy. This allows evaluation of multiple configurations in silico before committing to physical fabrication, enabling optimization of surface finish and mechanical properties.
2Strength
If multiple orientations and parameter sets are evaluated through simulation, then manufacturing precision and mechanical strength are improved, but the fabrication time and computational resources increase
Solution Approach 1:
Simulation of multiple orientations and parameter sets is performed in advance before actual fabrication. This preliminary evaluation identifies the optimal configuration, ensuring maximum mechanical strength while avoiding time-consuming trial-and-error physical fabrication of suboptimal designs.
Solution Approach 2:
Virtual copies of the object are simulated in different orientations to evaluate mechanical strength characteristics. This computational approach allows rapid assessment of multiple configurations without the time penalty of physical prototyping and testing.
3Productivity
If optimal orientation is determined through simulation based on user-defined objectives, then production efficiency is improved, but the system complexity and computational requirements increase
Solution Approach 1:
The system automatically determines optimal orientation and fabrication parameters by evaluating simulation results against user-defined objectives. This self-service capability eliminates the need for manual optimization and enables rapid selection of parameters that maximize production efficiency without requiring complex user intervention.
Solution Approach 2:
The system uses feedback from simulation results to automatically adjust and select optimal fabrication parameters. By comparing simulated outcomes against defined objectives, the system iteratively identifies the best configuration, improving productivity through data-driven decision-making.
