Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If PH measurement using electrodes is used to infer turbidity, then the measurement process is simple, but the measurement precision deteriorates due to interference from dust, pollution, and debris
Solution Approach 1:
The patent replaces the chemical/electrical measurement method (pH electrodes) with an optical measurement system. A light source emits light through the water sample, and a photodetector measures the transmitted light intensity. The turbidity is determined by the attenuation of light, which provides accurate measurements even in the presence of various contaminants that interfere with pH-based methods.
2Ease of operation
If an intermediate reservoir is used to store and measure turbid water, then the measurement process can be performed, but the reliability deteriorates due to contamination from decanted mud and suspended micro contaminants
Solution Approach 1:
The patent implements upstream filtration before the water reaches the measurement section. A filter removes debris, leaves, branches, and other particulate contaminants from the water flow before turbidity measurement. This preliminary cleaning action prevents contamination of the measurement system and ensures reliable, accurate readings without requiring intermediate reservoirs that could introduce their own contamination risks.
3Ease of manufacture
If manual deviation of rainwater flow is used to separate clean and turbid water, then the process is simple to implement, but the productivity deteriorates due to manual operation requirements
Solution Approach 1:
The patent implements an automated control system that continuously monitors water quality parameters (turbidity, pH, conductivity) and automatically controls the deviation mechanism to separate clean and turbid water. The system self-regulates based on sensor feedback, eliminating the need for manual operation while maintaining high separation efficiency and enabling continuous processing of large water volumes.
Solution Approach 2:
The patent employs a closed-loop control system where sensors continuously monitor water quality parameters and feed this information back to the control unit. The control unit adjusts the deviation mechanism in real-time based on the feedback signals, ensuring optimal separation of clean and turbid water automatically. This feedback mechanism enables high productivity with automated decision-making based on actual water conditions.
