Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a full CAD model is used to represent component geometry, then manufacturing precision and design accuracy are maintained, but file size becomes large and transfer efficiency deteriorates
Solution Approach 1:
The patent extracts only the essential geometric information needed for interface integration from the complete CAD model. Instead of transferring the entire high-fidelity CAD model, the system extracts and transfers only the tessellated geometry data required for interface control, significantly reducing file size while maintaining necessary precision for integration activities.
Solution Approach 2:
The patent applies local quality by providing different levels of geometric detail in different regions. The tessellated model focuses computational and data resources on accurately representing interface regions where precision is critical, while using coarser representation for non-critical areas, optimizing the balance between accuracy and file size.
2Ease of operation
If a lightweight tessellated model is used to reduce file size, then transfer efficiency and collaboration ease are improved, but manufacturing precision and design detail may be lost
Solution Approach 1:
The patent creates a tessellated copy of the essential geometric features from the original CAD model. This copy maintains sufficient fidelity for interface control and integration purposes while being significantly lighter in file size. The tessellated model serves as an adequate reproduction for collaboration without requiring the full original model.
3Adaptability or versatility
If interface control information is embedded in the tessellated model file, then integration capability among multiple entities is improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent merges interface control information, geometric data, and metadata into a single integrated tessellated model file. This consolidation allows all necessary information for interface control and integration to be contained in one file, improving collaboration efficiency and eliminating the need to manage multiple separate files or data sources.

AI summary
A user interface for a lightweight viewer may include a viewing window operable to display geometry established by geometric objects of a tessellated model. Groups of the geometric objects may be associated with the geometry of respective components of an assembly. Annotation objects of the tessellated model may be operable to depict annotation information associated with the tessellated model as graphical annotations in the viewing window. The groups of the geometric objects may be assigned to two or more responsible entities according to an interface requirements definition, The annotation information may be associated with one or more interfaces between adjacent components of the assembly according to the interface requirements definition.
