Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional welding simulation techniques are used, then the simulation can be performed with basic computational resources, but the manufacturing precision and reliability of the weld bead model deteriorate
Solution Approach 1:
The weld bead is segmented into multiple cross-sections along its length. Each cross-section is modeled independently with specific geometric parameters (width, height, area, perimeter). This segmentation allows precise modeling of the weld bead morphology while reducing computational complexity by breaking down the continuous three-dimensional model into discrete two-dimensional sections.
Solution Approach 2:
The invention transitions from modeling the weld bead as a continuous three-dimensional object to representing it through a series of two-dimensional cross-sections. This dimensional reduction simplifies the computational requirements while maintaining the ability to accurately represent the weld bead's geometric and mechanical properties through the sequence of cross-sectional parameters.
2Reliability
If real welding tests are performed to obtain mechanical properties data, then the reliability of the data is improved, but the loss of substance and loss of time increase significantly
Solution Approach 1:
The invention creates a virtual copy of the welding process through simulation. Instead of performing physical welding tests that consume material and time, the system replicates the welding process computationally, generating weld bead cross-sections and calculating their mechanical properties (such as tensile strength, shear strength, and elongation) through mathematical models. This virtual copying eliminates material consumption while providing reliable predictive data for weld quality assessment.
3Adaptability or versatility
If conventional welding simulation systems are used, then the simulation can be performed, but the ease of operation and adaptability deteriorate due to limited device compatibility
Solution Approach 1:
The welding simulation system is designed with universal applicability across multiple device types and platforms. The cross-sectional modeling approach and computational algorithms can be implemented on various hardware configurations, from high-performance workstations to mobile devices and web browsers. This multi-functionality allows the same simulation methodology to operate efficiently across different computing environments, enhancing both adaptability and ease of deployment.
