Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a detection kit using monoclonal antibody is used to detect attachment-stage larvae of barnacles, then detection accuracy is improved, but continuous monitoring becomes impossible and detection cost increases
Solution Approach 1:
The invention creates a digital copy of the barnacle larvae characteristics through image data and machine learning models. Instead of using physical monoclonal antibodies for each detection, the system captures images of larvae and uses trained neural networks to identify and count them, enabling continuous automated monitoring without consuming physical reagents.
Solution Approach 2:
The invention replaces the biochemical detection mechanism (monoclonal antibody binding) with an optical and computational system. Images are captured by imaging devices and processed by machine learning algorithms, substituting the mechanical/chemical detection process with an information-based system that enables continuous operation.
2Reliability
If chemical such as chlorine-based chemical is injected into cooling water to suppress attachment of organisms, then attachment suppression is improved, but environmental impact increases and chemical cost increases
Solution Approach 1:
The invention implements a feedback control system where the detection device continuously monitors barnacle larvae in the cooling water, and the control device adjusts chemical injection based on the detected larva count. This closed-loop feedback enables precise chemical dosing - injecting chemicals only when larvae are detected and in appropriate amounts, thereby reducing overall chemical usage and environmental impact while maintaining effective attachment suppression.
Solution Approach 2:
The system dynamically changes the chemical injection parameters (amount and timing) based on detected larva concentrations. Instead of continuous or fixed-dose chemical injection, the system adjusts the chemical dosage parameter according to the actual biological threat level, optimizing the balance between effectiveness and environmental impact.
3Reliability
If chemical is injected into cooling water to suppress attachment of organisms, then attachment suppression is improved, but chemical cost increases
Solution Approach 1:
The detection device provides real-time feedback on larva presence and concentration to the control device, which adjusts chemical injection accordingly. This feedback mechanism ensures chemicals are injected only when necessary and in the minimum effective amount, reducing overall chemical consumption while maintaining attachment suppression effectiveness.
Solution Approach 2:
Instead of injecting chemicals continuously or in excess to ensure coverage, the system applies partial action - injecting chemicals only when larvae are detected and in precisely the amount needed based on larva count. This targeted approach reduces chemical usage while maintaining sufficient suppression effectiveness.
