Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing three-dimensional editing systems are used, then detailed editing capability is provided, but the system becomes cumbersome and requires expert knowledge
Solution Approach 1:
The patent introduces an implicit function as an intermediary representation between the user interface and the high-resolution three-dimensional model. Users interact with simplified parameter handles that modify the implicit function, which then automatically transfers modifications to the detailed model. This intermediary layer eliminates the need for users to directly manipulate complex mesh structures while preserving high-resolution details.
Solution Approach 2:
The editing system is segmented into distinct components: parameter handles for user interaction, implicit function for intermediate representation, and the high-resolution model for detail preservation. This segmentation allows each component to handle specific tasks independently, reducing overall system complexity while maintaining detailed editing capability.
2Manufacturing precision
If existing editing systems operate on low-resolution models, then editing simplicity is achieved, but high-resolution details are lost
Solution Approach 1:
The system creates and maintains an implicit function copy or representation of the high-resolution three-dimensional model. This implicit representation captures the essential geometric features and can be modified independently without affecting the original high-resolution mesh. Modifications to the implicit function are then transferred back to update the detailed model, preserving manufacturing precision while simplifying the editing process.
3Adaptability or versatility
If procedural modeling systems use parameters and rules, then shape generation capability is improved, but flexibility and accuracy in editing are reduced
Solution Approach 1:
The system dynamically adapts between different representation levels. The implicit function provides a low-frequency, flexible framework for semantic modifications, while the high-resolution mesh preserves detailed geometric accuracy. The system dynamically transfers modifications from the flexible implicit representation to the detailed mesh representation, achieving both adaptability and precision.
