Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If modern AI-based classification methods are used, then decision quality is improved, but learning time and data requirements increase
Solution Approach 1:
The system performs preliminary feature extraction using a neural network to generate a comprehensive feature set from container part images. These pre-extracted features are then used for rapid classification without requiring retraining when new container types are introduced, thus reducing learning time while maintaining high decision quality
Solution Approach 2:
The inspection system is segmented into two independent components: a neural network-based feature extraction module and a classical classification module. The feature extraction is performed once and stored, while classification is performed rapidly using the pre-extracted features, separating the computationally intensive task from the rapid decision-making process
2Adaptability or versatility
If classical classification methods are used, then adaptability is improved, but measurement precision deteriorates
Solution Approach 1:
The system performs preliminary feature extraction using a neural network to generate a comprehensive feature set from container part images. These pre-extracted features are then used for rapid classification without requiring retraining when new container types are introduced, thus reducing learning time while maintaining high decision quality
Solution Approach 2:
The neural network acts as an intermediary that extracts robust features from images, which are then fed to classical classification algorithms. This intermediary layer enables classical algorithms to benefit from the sophisticated feature representation learned by the neural network, combining adaptability with high measurement precision
3Measurement precision
If extensive training data is used, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system extracts and pre-computes feature representations using a neural network, separating the complex feature learning process from the classification process. This extraction of meaningful features reduces the complexity of the overall system by allowing simple classical classifiers to work with pre-processed data
Solution Approach 2:
The system creates a reusable feature extraction model that can be applied to multiple inspection tasks without requiring retraining. The learned features are copied and stored, allowing rapid deployment to new container types without proportionally increasing system complexity or training data requirements
