Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If internal structures are added to a 3D model, then functionality and interactivity are improved, but structural integrity deteriorates and the object becomes unstable
Solution Approach 1:
The system performs preliminary analysis of the 3D model to identify optimal locations and configurations for internal structures before they are added. By pre-calculating placement strategies that maintain structural integrity, the system prevents instability rather than correcting it later, resolving the contradiction between adding functional structures and maintaining strength.
2Adaptability or versatility
If multiple internal structures are added to a 3D model, then functionality is improved, but interference between structures increases
Solution Approach 1:
The system implements a feedback mechanism that automatically detects and resolves interference between multiple internal structures. When structures are added to the 3D model, the system analyzes their spatial relationships and adjusts their positions or configurations to eliminate harmful interactions, allowing multiple functional structures to coexist without interference.
3Strength
If manual design iterations are performed to create internal structures, then structural integrity can be maintained, but time consumption increases
Solution Approach 1:
The system performs self-service by automatically analyzing the 3D model, determining optimal internal structure configurations, and generating placement recommendations without requiring manual design iterations. The automated structural integrity analysis and interference detection capabilities eliminate the need for repeated manual testing while maintaining structural strength, significantly reducing design time.
4Adaptability or versatility
If internal structures are added to enable interactivity, then adaptability is improved, but the object becomes easily broken
Solution Approach 1:
The system optimizes the parameters of internal structures (such as thickness, material distribution, and geometric configuration) to maintain reliability while enabling interactivity. By adjusting these parameters based on structural analysis, the system ensures that interactive features do not compromise the overall stability and durability of the 3D printed object.

AI summary
One embodiment of the present invention sets forth a technique for generating a tube within a three-dimensional (3D) model. The technique involves receiving a first location on a surface of the 3D model. The technique further involves receiving a second location on the surface of the 3D model. The technique further involves receiving at least one constraint associated with a first tube to be generated within the 3D model. The technique further involves generating, based on the at least one constraint, the first tube, where the first tube connects a first opening at the first location with to a second opening at the second location.
