Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If common detection techniques are used, then the detection system is simple, but the detection precision and classification accuracy are insufficient
Solution Approach 1:
The detection system is segmented into multiple specialized detection devices, each optimized for specific plastic size ranges (macro-plastics, micro-plastics, nano-plastics). This segmentation allows each component to focus on a specific measurement task, improving overall detection precision without requiring a single complex system to handle all sizes simultaneously.
Solution Approach 2:
The system employs a multi-functional detection platform that can detect and classify plastics across different size ranges using various detection wavelengths. The universal system integrates multiple detection capabilities (optical, acoustic, magnetic) into a single coordinated platform, achieving high precision while managing complexity through functional integration rather than separate systems.
2Measurement precision
If multiple detection wavelengths are used, then the classification accuracy is improved, but the device complexity increases
Solution Approach 1:
The detection system dynamically selects and switches between different detection wavelengths based on the suspected plastic size and type. This dynamic wavelength selection allows the system to optimize classification accuracy for each specific detection task while avoiding the need to simultaneously maintain all possible wavelengths active, thereby managing device complexity through adaptive operation.
Solution Approach 2:
The system changes detection parameters (wavelength, sensitivity thresholds, processing algorithms) based on the target plastic characteristics. By adjusting these parameters dynamically rather than maintaining fixed complex settings, the system achieves high classification accuracy while simplifying the underlying device architecture through parameter-based adaptation rather than hardware complexity.
3Loss of information
If detailed detection and classification is performed, then the information quality is improved, but the processing time increases
Solution Approach 1:
The system performs preliminary classification actions by first detecting the size range and type of plastic before applying detailed analysis. This preliminary sorting allows the system to apply appropriate detection wavelengths and processing algorithms in advance, improving information quality while reducing overall processing time by avoiding unnecessary detailed analysis of already classified items.
Solution Approach 2:
The detection and classification process operates continuously with parallel processing of multiple plastic types and sizes simultaneously. Rather than sequential analysis, the system maintains continuous detection across different wavelength ranges and classification categories, improving information quality through comprehensive monitoring while minimizing processing time through parallel rather than sequential operations.

AI summary
A system for detecting plastics, macro-plastics, micro-plastics and nano-plastics in a maritime, estuary or river environment includes multiple detection devices and a data processing device. The detection devices detect the plastics, macro-plastics, micro-plastics, and nano-plastics using different detection wavelengths. The data processing device includes a communication interface and a processor. The communication interface receives detection signals from the detection devices and the processor determines locations of the plastics, the macro-plastics, the micro-plastics and the nano-plastics in the environment based at least in part on the received detection signals within a common coordinate system.
