1Measurement precision
If physical reference objects are used for welding quality evaluation, then measurement accuracy is improved, but adaptability to varying environmental conditions deteriorates
Solution Approach 1:
The patent creates virtual reference shapes as digital copies of ideal weld geometries. These virtual references can be generated and modified computationally to match any environmental condition or welding scenario, eliminating the need for physical reference objects while maintaining measurement accuracy through precise digital modeling and comparison.
2Adaptability or versatility
If virtual reference shapes generated by GANs are used for welding evaluation, then adaptability to different conditions is improved, but device complexity deteriorates
Solution Approach 1:
The patent replaces complex physical reference object creation and management systems with a computational GAN-based virtual reference generation system. This substitution uses machine learning models to automatically generate appropriate reference shapes for any welding condition, reducing the need for extensive physical reference libraries and complex manual configuration procedures.
3Device complexity
If traditional welding evaluation methods are used, then device complexity is reduced, but manufacturing precision deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where actual weld shapes are compared against GAN-generated virtual reference shapes, and the results are used to iteratively improve the GAN model's ability to generate accurate references. This feedback loop continuously enhances welding quality assessment accuracy while maintaining system simplicity through automated learning and adaptation.
