Solid Modeling System Detects Component Hole Gaps for Weld Beads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solid modeling systems lack an efficient method to detect component hole gaps and generate accurate weld beads, particularly in complex geometric cases, which hinders the precise representation and generation of fillet and groove welds.
Innovation Solution
A computer-implemented solid modeling system that detects component hole gaps by analyzing internal loops of components and generates fillet or groove weld beads to fill these gaps, using techniques such as Thicken and Sweep methods for groove welds, and facial characteristic-based methods for fillet welds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional solid modeling systems are used to generate weld beads, then basic weld representation is achieved, but accurate detection of component hole gaps and precise weld bead generation in complex geometric cases is not achieved
Solution Approach 1:
The system segments the complex geometric analysis into distinct components: identifying internal loops of the first component, determining which loops encircle the second component, detecting gaps between components, and generating weld beads. This segmentation allows each sub-task to be handled by specialized algorithms, improving detection accuracy while managing system complexity through modular organization of the detection process.
2Manufacturing precision
If simple weld bead generation methods are used, then processing speed is maintained, but accurate weld bead generation for complex geometric cases is not achieved
Solution Approach 1:
The system performs preliminary actions by first identifying internal loops and determining their encirclement relationships before gap detection and weld bead generation. This preliminary analysis of the geometric topology enables the system to accurately identify gap locations and select appropriate weld bead generation methods, ensuring manufacturing precision while maintaining processing efficiency through organized pre-computation.

AI summary
A computer-implemented solid modeling system that determines whether a gap exists between components based on internal loops of the components, and then generates a fillet or groove weld bead that fills the gap between the components. The gap is a component hole gap between components where one or more internal loops of a first component fully or partially encircles a second component, and the valid internal loops identify whether the second component passes through the first component through the component hole gap.
