Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual assignment of attributes to multiple three-dimensional elements is used, then accuracy of attribute assignment can be ensured, but time consumption and operational efficiency deteriorate
Solution Approach 1:
The patent uses two-dimensional shape data as a template or copy to automatically generate and assign attributes to three-dimensional elements. The attribute information extracted from the 2D shape data is copied and applied to corresponding 3D elements, eliminating manual assignment while maintaining accuracy through the structured relationship between 2D and 3D representations.
Solution Approach 2:
The patent replaces the mechanical manual process of attribute assignment with an automated computational system. The processor automatically extracts attribute information from two-dimensional shape data and assigns it to three-dimensional elements, substituting human operation with algorithmic processing to reduce time consumption while maintaining precision.
2Ease of operation
If manual assignment of attributes to each three-dimensional element is performed, then control over attribute details can be maintained, but operational complexity and time requirement increase
Solution Approach 1:
The system performs self-service by automatically extracting attribute information from two-dimensional shape data and assigning it to three-dimensional elements without requiring manual intervention. The processor autonomously completes the attribute assignment task, making the operation easier and faster by eliminating the need for users to manually assign attributes to each element.
Solution Approach 2:
The patent performs preliminary extraction of attribute information from two-dimensional shape data before the actual three-dimensional shape data generation. This preliminary action prepares the attribute information in advance, so that during the 3D data generation process, attributes can be automatically assigned without delay, significantly reducing overall processing time.
3Productivity
If automatic attribute assignment from two-dimensional data is implemented, then productivity and speed improve, but system complexity increases
Solution Approach 1:
The patent implements a universal system where the processor performs multiple functions: obtaining two-dimensional shape data, extracting attribute information, and assigning attributes to three-dimensional elements. This multi-functional approach consolidates what could be separate complex operations into a unified process, improving productivity while managing system complexity through integration rather than multiplication of components.
