1Productivity
If automatic extraction of coupling relationship from CAD data is used, then extraction efficiency is improved, but accuracy of motion simulation deteriorates
Solution Approach 1:
The system divides the coupling relationship definition into two segments: automatic extraction of basic coupling relationships from CAD data (improving efficiency) and manual adjustment of coupling parameters (improving accuracy). This segmentation allows each method to contribute its strengths to the overall solution.
Solution Approach 2:
The system performs preliminary automatic extraction of coupling relationships from CAD data before the simulation process. This preliminary action provides a initial configuration that can then be refined through manual adjustment, combining the benefits of automation with precision tuning.
2Manufacturing precision
If manual adjustment of coupling relationship is allowed, then accuracy of motion simulation is improved, but operation complexity increases
Solution Approach 1:
The system provides dynamic coupling relationship definition where parameters can be adjusted during the simulation setup process. The coupling relationships are not fixed but can be modified interactively, allowing users to fine-tune parameters while the system maintains the overall structure automatically extracted from CAD data.
Solution Approach 2:
The system introduces an intermediary adjustment layer between the automatic CAD data extraction and the final simulation execution. This intermediary layer provides a user-friendly interface for adjusting coupling parameters without requiring deep knowledge of the underlying CAD data structure, simplifying the operation while maintaining accuracy.
3Manufacturing precision
If comprehensive coupling parameters are defined, then simulation accuracy is improved, but device complexity increases
Solution Approach 1:
The system merges the automatic extraction process with manual adjustment capabilities into a unified coupling relationship definition system. By combining these two approaches, the system achieves comprehensive parameter definition without requiring separate complex systems for automatic extraction and manual configuration.
Solution Approach 2:
The system creates a universal coupling relationship management mechanism that handles both automatic extraction from various CAD data formats and manual adjustment of parameters through a single integrated interface. This multi-functional approach reduces overall system complexity compared to having separate specialized systems.

AI summary
A technique for adjusting a coupling relationship between components in a simulation includes a computer that is coded to obtain pieces of component data of an assembly, generate a coupling setting between one or more of the pieces of component data, receive an operation, adjust the coupling setting based on the operation, emulate, based on a user program, a controller that controls the assembly, and operate the assembly in a three-dimensional (3D) space. The operating the assembly includes operating, based on the adjusted coupling setting, the one or more pieces of component data in conjunction with each other.
