Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current digital image analysis systems are used, then defect detection capability is provided, but the system is expensive and requires expertise to adapt to new demands or defects
Solution Approach 1:
The system enables self-service through automated machine learning workflows where the system automatically trains and retrained models using new defect images without requiring expert intervention. The automated retraining process allows the system to adapt to new defects autonomously, resolving the contradiction between maintaining reliable defect detection and achieving adaptability to new demands.
Solution Approach 2:
The system performs preliminary action by pre-training machine learning models with extensive defect image data before deployment. This preliminary training establishes a baseline detection capability that can then be rapidly adapted to new defects through automated retraining, addressing both the need for initial reliability and future adaptability.
2Reliability
If current digital image analysis systems are used, then defect detection is performed, but the system is difficult and expensive to adapt or improve
Solution Approach 1:
The system performs self-service by automatically managing the model retraining process. When new defect images are collected, the system autonomously retrains the machine learning models without requiring manual expert intervention, making the system easy to adapt and improve while maintaining high detection accuracy.
Solution Approach 2:
The system implements feedback loops where detected defects and new defect images are fed back into the retraining process. This continuous feedback mechanism automatically improves model accuracy over time, resolving the contradiction between maintaining high detection reliability and enabling easy adaptation.
3Reliability
If traditional image analysis systems are used, then visible defects are detected, but the system cannot rapidly respond to newly discovered defects
Solution Approach 1:
The system exhibits dynamics by transitioning from static, pre-programmed detection rules to dynamic machine learning models that can be rapidly retrained. This allows the system to maintain reliable detection of known defects while rapidly adapting to newly discovered defects through automated retraining, resolving the contradiction between detection reliability and response productivity.
Solution Approach 2:
The system performs preliminary action by maintaining pre-trained models that can be quickly retrained when new defects are discovered. This preliminary preparation of the machine learning infrastructure enables rapid response to new defects without sacrificing the reliability of existing defect detection capabilities.
