Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If 3D CAD data is used for assembly processes, then design precision and visualization are improved, but component interference and tool placement difficulties arise
Solution Approach 1:
The system performs preliminary interference checking and tool placement verification on the 3D CAD model before actual assembly. By detecting potential component interferences and verifying tool accessibility in the virtual model, the system identifies and resolves assembly issues beforehand, preventing problems during physical assembly operations
Solution Approach 2:
The system creates a virtual copy of the assembly model from 3D CAD data to perform interference checking and tool placement verification. This virtual model allows designers to simulate and analyze assembly processes without affecting the actual physical assembly, enabling safe testing and validation of assembly sequences
2Reliability
If virtual models are generated for interference checking, then assembly verification is improved, but processing time and computational resources increase
Solution Approach 1:
The interference checking process is segmented into distinct phases: component extraction from 3D CAD data, virtual model generation, interference detection, and tool placement verification. By dividing the verification process into manageable segments, the system can efficiently process complex assemblies without overwhelming computational demands, reducing overall verification time

AI summary
A design support apparatus includes a processor configured to: extract a component from a three-dimensional model that includes a combination of multiple components; and display determination results, in a display form predetermined in the determination results, the determination results being obtained by determining whether a component other than the extracted component interferes with a virtual model, generated on the three-dimensional model, in a relationship between the virtual model and the extracted component.
