Aerospace Joggle Modeling with Intersecting Runouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current PDM systems lack the capability to efficiently manage and visualize joggle features on multiple adjacent web faces with intersecting runouts in CAD modeling, particularly in aerospace sheet metal design, where intermediate web faces are not adequately supported.
Innovation Solution
The method involves receiving a CAD model with selected multiple adjacent web faces and a datum plane, allowing for the creation of joggle features by offsetting portions of the web faces along specific directions and depths, resulting in intersecting runouts, and storing the modified model, which can include intermediate web faces in addition to end web faces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If PDM systems use traditional CAD modeling approaches for joggle features, then simple single-face joggles can be modeled, but complex joggle features on multiple adjacent web faces with intersecting runouts cannot be efficiently managed or visualized
Solution Approach 1:
The patent segments the complex joggle feature creation process into distinct operational phases: selecting multiple adjacent web faces, specifying offset parameters for each face, generating individual runouts, and merging them into a unified joggle feature. This segmentation allows the system to handle complex multi-face joggles by breaking them down into manageable sequential steps, thereby improving adaptability without proportionally increasing system complexity
Solution Approach 2:
The patent creates a universal joggle modeling capability that can handle multiple adjacent web faces simultaneously through a single integrated operation. The system accepts multiple web face selections and applies a unified joggle methodology across all selected faces, creating intersecting runouts automatically. This multi-functional approach enhances versatility by allowing the same tool to model both simple single-face and complex multi-face joggles without requiring separate specialized processes
2Ease of operation
If PDM systems support only end web faces for joggle features, then the modeling process remains simple, but intermediate web faces cannot be adequately supported
Solution Approach 1:
The patent merges the modeling approach for end web faces and intermediate web faces into a single unified process. By allowing selection of multiple adjacent web faces including intermediates, and automatically handling the geometric relationships between them, the system combines previously separate modeling tasks into one integrated operation. This merging maintains ease of operation through a consistent interface while significantly improving versatility by enabling support for all web face types
3Productivity
If PDM systems create joggle features without intersecting runout capability, then the modeling process is straightforward, but complex deformations with intersecting runouts cannot be produced
Solution Approach 1:
The patent performs preliminary actions by automatically generating the intersecting runout geometry before finalizing the joggle feature. The system pre-calculates the runout intersections based on the selected web faces and offset parameters, preparing the geometric framework in advance. This preliminary generation of complex intersecting geometry maintains modeling efficiency by automating what would otherwise require manual intervention, while simultaneously achieving high deformation accuracy through precise geometric computation

AI summary
Methods for CAD modeling and corresponding systems and computer-readable mediums. A method includes receiving a CAD model including a selection of multiple adjacent web faces of the CAD model and at least one datum plane of the CAD model that intersects the web faces, receiving a selection of a joggle side of the CAD model with respect to the datum plane, and receiving an offset direction and an offset depth value corresponding to each selected web face. The method includes creating at least one joggle feature in the CAD model by moving a portion of each of the selected web faces on the joggle side of the CAD model according to the respective offset directions and the depth values, including creating at least one runout for each selected web face at the datum plane, to produce a modified CAD model. The method includes storing the modified CAD model. The multiple adjacent web faces can include intermediate web faces.
