Engineering Contradiction Analysis
1Measurement precision
If three-dimensional operations are performed on the CAD device to create a pipe network model, then the accuracy of the flow calculation is improved, but the ease of operation deteriorates due to the significant effort required to acquire expertise
Solution Approach 1:
The patent applies the copying principle by creating a two-dimensional plan view representation of the three-dimensional pipe network. Instead of requiring users to perform complex 3D operations, the system copies the essential layout information into a 2D format that is much easier to create and manipulate, while still preserving the necessary spatial relationships for accurate flow calculation.
Solution Approach 2:
The patent transforms the problem from three-dimensional space to two-dimensional space by creating plan views of the pipe network. This dimensionality change simplifies the user interface and operation while maintaining the essential geometric information needed for accurate calculations through coordinate transformation.
2Measurement precision
If three-dimensional operations are performed on the CAD device to create a pipe network model, then the accuracy of the flow calculation is improved, but the time required for model creation increases
Solution Approach 1:
The system creates a 2D plan view copy of the 3D pipe network layout, which can be generated much more quickly than performing full 3D modeling operations. This copying approach preserves the essential spatial information while dramatically reducing the time investment required for model creation.
Solution Approach 2:
The patent performs preliminary coordinate transformation and projection operations to convert 3D coordinates into 2D plan view coordinates before the main modeling process. This preliminary action simplifies subsequent operations and reduces the overall time required for model creation while maintaining calculation accuracy.
3Measurement precision
If the pipe network model strictly reflects the three-dimensional layout, then the flow calculation accuracy is improved, but the device complexity increases due to the need for three-dimensional coordinate handling
Solution Approach 1:
The patent reduces the complexity by projecting three-dimensional coordinates onto a two-dimensional plane, creating plan views that eliminate the need for users to directly handle 3D coordinate systems. The transformation mathematically preserves the necessary spatial relationships while simplifying the operational interface.
Solution Approach 2:
The system introduces a coordinate transformation mechanism as an intermediary between the simple 2D plan view input and the 3D flow calculation requirements. This intermediary automatically handles the complex coordinate conversions, allowing users to work with simple 2D layouts while maintaining accurate 3D calculation capabilities.
