Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single evaluation method is used for all welding points, then the evaluation process is simple, but the welding quality assessment becomes inconsistent across different points
Solution Approach 1:
The patent divides the welding evaluation system into multiple determination algorithms, each specifically designed for individual welding points. This segmentation allows each welding point to be evaluated with a customized algorithm that accounts for its specific characteristics, thereby improving assessment consistency without requiring a single overly complex universal algorithm.
Solution Approach 2:
The patent implements local quality by associating different determination algorithms with different welding points based on their specific requirements. Each welding point receives a tailored evaluation approach rather than a uniform method, ensuring that the assessment matches the local characteristics of each welding location.
2Measurement precision
If detailed analysis of welding conditions is performed for each welding point, then evaluation accuracy improves, but the construction and implementation becomes more difficult
Solution Approach 1:
The patent segments the complex evaluation task into multiple simpler determination algorithms, each handling a specific welding point. This division reduces the construction difficulty for each individual algorithm while maintaining high overall evaluation accuracy through the collective contribution of all algorithms.
Solution Approach 2:
The patent creates a framework where determination algorithms can be systematically applied across multiple welding points. While each algorithm is customized for its specific welding point, they all follow a unified structure and methodology, making the overall system manageable and reducing implementation difficulty through standardized approaches.
