Curved Extrusion Modeling via Adjustable Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sweep modeling techniques require users to have extensive knowledge of 3D modeling geometry and explicitly define non-planar space curves, making it difficult to generate curved extrusions efficiently and intuitively.
Innovation Solution
A method using user-adjustable parameters such as depth, X angle, Y angle, scale, and twist to control the shape of curved extrusions, allowing users to modify these parameters via a user interface without explicitly defining the sweep path, and enabling the generation of complex shapes more intuitively and quickly.

Engineering Contradiction Analysis
1Manufacturing precision
If conventional sweep modeling techniques are used to generate curved extrusions, then the user can explicitly define and control the sweep path geometry, but the user requires extensive knowledge of 3D modeling geometry and the operation becomes difficult and time-consuming
Solution Approach 1:
The patent transforms the complex geometric control of sweep paths into simple parameter adjustments. Instead of requiring users to manually edit non-planar space curves point-by-point, the system provides a set of extrusion parameters (such as bend angles, twist angles, and control point positions) that automatically generate the sweep path when adjusted, making the operation intuitive and accessible to users without extensive 3D modeling knowledge
Solution Approach 2:
The patent introduces an intermediary computational process that translates simple parameter inputs into complex sweep path geometry. The system acts as a mediator between the user's intuitive parameter adjustments and the underlying geometric modeling operations, automatically calculating and generating the appropriate non-planar space curves without requiring direct user manipulation of the complex geometry
2Manufacturing precision
If users directly modify the sweep path point-by-point to obtain curved extrusions, then the sweep path can be precisely controlled, but the operation becomes a difficult and time-consuming task
Solution Approach 1:
The system replaces point-by-point sweep path editing with parameter-based control. Users adjust high-level extrusion parameters (bend angles, twist angles, depth, scale) that automatically generate the complete sweep path geometry, reducing the time required from manual point editing to simple parameter input while maintaining precise control over the final shape
Solution Approach 2:
The system performs preliminary computational action by automatically generating the sweep path geometry based on parameter inputs before the user needs to see or interact with the final extrusion. This pre-computation of the sweep path from parameters eliminates the need for iterative point-by-point editing, significantly reducing the time required to achieve the desired curved extrusion
3Adaptability or versatility
If conventional sweep modeling tools are used, then the user can generate curved extrusions, but the user needs extensive knowledge of sweep modeling tools and 3D modeling geometry
Solution Approach 1:
The patent abstracts complex 3D modeling operations into a simple parameter adjustment interface. Instead of requiring users to understand sweep modeling theory and manually construct space curves, the system provides intuitive parameters (bend angle, twist angle, depth, scale, control point positions) that directly control the extrusion shape, making the tool accessible to users without specialized 3D modeling knowledge while maintaining full capability to generate complex curved extrusions
