Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If deep learning networks are used for endoscopic image segmentation, then segmentation accuracy is improved, but computational complexity and resource consumption increase significantly
Solution Approach 1:
The patent segments the deep learning model into two distinct components: a lightweight backbone network for feature extraction and a segmentation head for boundary prediction. This segmentation allows each component to be optimized independently, reducing overall model complexity while maintaining segmentation accuracy through specialized function division.
Solution Approach 2:
The patent extracts and emphasizes only the most critical features for endoscopic image segmentation by using a simplified backbone network that focuses on extracting essential lesion characteristics. This extraction approach removes unnecessary computational complexity while preserving the accuracy needed for medical diagnosis.
2Measurement precision
If larger and deeper neural networks are used to achieve better segmentation performance, then segmentation accuracy is improved, but inference speed decreases and computational resources are consumed more
Solution Approach 1:
The patent changes key model parameters by using a lightweight backbone with fewer layers and parameters compared to traditional deep networks. This parameter optimization maintains segmentation accuracy by focusing computational resources on the most discriminative features while significantly improving inference speed for real-time clinical application.
Solution Approach 2:
The patent applies partial action by implementing only the essential components needed for accurate segmentation rather than using complete deep network architectures. The simplified model performs the minimum necessary computational operations to achieve diagnostic-level accuracy, thereby maintaining high inference speed.
3Ease of manufacture
If classical segmentation algorithms are used, then computational requirements are low, but segmentation accuracy is insufficient
Solution Approach 1:
The patent introduces a lightweight deep learning model as an intermediary between classical segmentation algorithms and complex deep networks. This intermediary model provides the enhanced accuracy needed for medical diagnosis while maintaining computational efficiency similar to classical algorithms, effectively bridging the gap between speed and precision requirements.
