Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional multi-camera systems or complex measurement devices are used to estimate fish growing day, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses a single-lens camera to capture images of fish, creating a visual copy that can be analyzed to estimate growing day. This replaces complex multi-camera systems or specialized measurement devices with a simple imaging device, achieving the desired measurement precision while significantly reducing device complexity and cost.
Solution Approach 2:
The patent replaces mechanical or complex optical measurement systems with an image-based approach. By capturing fish images and analyzing key point coordinates through software processing, the system achieves accurate growing day estimation without requiring complex mechanical measurement devices or multiple cameras.
2Measurement precision
If advanced multi-camera systems are used for fish growth monitoring, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system uses a simple single-lens camera to capture fish images, creating visual copies that are processed automatically. This approach maintains measurement precision while dramatically improving ease of operation, as the single camera is much easier to position, operate, and maintain compared to complex multi-camera systems.
Solution Approach 2:
The system performs automatic key point detection and growing day estimation from captured images without requiring manual measurement or complex system configuration. The automated processing of image data and calculation of growing day from key point coordinates eliminates the need for operators to manage complex multi-camera systems, significantly improving ease of operation.
3Productivity
If comprehensive biometric analysis is performed on fish images, then productivity is improved through better growth management, but device complexity increases
Solution Approach 1:
The patent extracts only the essential key points from fish images that are necessary for growing day estimation, rather than performing comprehensive analysis of all image features. By focusing on specific key point coordinates and their relationships, the system achieves effective growth management while keeping the analysis complexity low and the processing efficient.
