Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional water treatment processes are used, then water can be supplied through filtration, but microbes may unintentionally proliferate during treatment
Solution Approach 1:
The patent implements real-time monitoring of water quality parameters during treatment processes. Sensors continuously measure microbial presence and water quality metrics, feeding this information back to control systems that can immediately adjust treatment parameters to prevent microbial proliferation while maintaining effective filtration
Solution Approach 2:
The patent introduces intermediate treatment stages and barrier systems between the water source and final distribution. These intermediate measures include multiple filtration layers, disinfection barriers, and monitoring checkpoints that collectively prevent microbial proliferation without compromising the overall water treatment effectiveness
2Measurement precision
If conventional detection methods are used, then water can be examined, but it is very difficult to sense a minimum amount of microbes in the fluid
Solution Approach 1:
The patent employs advanced detection methods that measure multiple parameters simultaneously (turbidity, absorbance at different wavelengths, fluorescence) rather than relying on a single measurement. By analyzing changes in multiple parameters and their relationships, the system can detect very low concentrations of microbes that would be imperceptible using conventional single-parameter methods
Solution Approach 2:
The patent uses composite detection approaches combining multiple sensing technologies and analysis methods. By integrating different detection principles (optical scattering, absorbance spectroscopy, fluorescence detection) and combining their outputs through data fusion algorithms, the system achieves enhanced sensitivity for detecting minimum amounts of microbes in water
