Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing insect recognition models are used, then insect identification can be performed, but the models struggle to generalize across different datasets due to domain shift
Solution Approach 1:
The patent applies domain adaptation techniques that transform the parameters and distributions of source domain features to match target domain characteristics. By learning domain-invariant features and adjusting model parameters through unsupervised domain adaptation, the system maintains reliable performance across different datasets and environmental conditions.
Solution Approach 2:
The patent introduces domain adaptation layers and feature alignment mechanisms as intermediaries between the source domain training data and target domain application. These intermediary components bridge the domain gap by aligning feature distributions and reducing domain shift effects, enabling better generalization without requiring extensive target domain labeled data.
2Measurement precision
If large amounts of labeled data are used for training, then model accuracy improves, but data collection and labeling costs increase
Solution Approach 1:
The patent implements self-supervised learning mechanisms where the model learns from unlabeled target domain data through domain adaptation. The system automatically adapts to target domain characteristics without requiring manual labeling, using techniques like feature alignment and domain-invariant representation learning to achieve high accuracy with minimal labeled data.
Solution Approach 2:
The patent uses a small subset of labeled data from the source domain combined with大量 unlabeled target domain data. By applying domain adaptation, the model achieves performance comparable to or exceeding models trained on large amounts of labeled data from each specific domain, reducing the overall labeling burden.
3Adaptability or versatility
If optimal transport methods are used for domain adaptation, then feature alignment improves, but computational costs increase
Solution Approach 1:
The patent extracts and focuses on the most critical aspects of optimal transport for domain adaptation, implementing simplified versions that capture the essential feature alignment benefits while removing computationally expensive components. By selectively applying domain adaptation techniques only to key feature representations rather than entire datasets, the system achieves effective alignment with reduced computational overhead.
Solution Approach 2:
The patent divides the domain adaptation process into multiple stages and layers, applying computationally intensive optimal transport methods only where most beneficial while using lighter techniques elsewhere. This segmented approach allows effective feature alignment in critical regions while maintaining overall computational efficiency.
