Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional water quality detection methods are used, then the device complexity is reduced, but the measurement precision deteriorates due to polarization effects and inaccurate detection
Solution Approach 1:
The patent applies periodic action by alternating the current direction through the aqueous solution at regular intervals. The control module switches the current direction periodically, allowing measurement during intervals when polarization effects are minimal, thus improving measurement precision while using a relatively simple detection circuit
Solution Approach 2:
The patent implements dynamics by making the current direction changeable rather than fixed. The control module dynamically adjusts the current direction based on measurement needs, enabling the system to adapt to polarization effects and achieve accurate water quality detection without complex circuitry
2Measurement precision
If bidirectional conduction conductimetric method with periodic current direction change is used, then the measurement precision is improved by reducing polarization effects, but the device complexity increases due to current control module
Solution Approach 1:
The control module serves multiple functions: it controls the current direction switching, manages the measurement timing, and coordinates the data processing. This multi-functionality reduces the need for separate dedicated components, thereby improving measurement precision while keeping the overall device complexity manageable
Solution Approach 2:
The system performs self-service by automatically switching current directions and selecting appropriate measurement intervals without external intervention. The control module autonomously manages the bidirectional conduction process, reducing the need for additional control hardware and simplifying the overall system
3Adaptability or versatility
If geographical location-based resistance threshold adjustment is implemented, then the adaptability is improved for different water qualities, but the device complexity increases due to location acquisition and network modules
Solution Approach 1:
The patent uses geographical location information as an intermediary to select appropriate water quality standards. Instead of directly measuring and comparing against multiple complex standards, the system uses location data to automatically retrieve the relevant threshold, thereby improving adaptability while keeping the device complexity relatively low through modular design
4Measurement precision
If temperature compensation is applied to resistance measurement, then the measurement precision is improved, but the device complexity increases due to temperature control module
Solution Approach 1:
The patent implements feedback by continuously monitoring the temperature of the aqueous solution and using this information to compensate the resistance measurements. The temperature control module provides real-time temperature data to the data processing module, which adjusts the resistance threshold accordingly, improving measurement precision while using a relatively simple feedback-based temperature compensation mechanism
