Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a valve is used to adjust concentrated water discharge, then manual control is simple, but precise control cannot be achieved leading to water waste or unqualified purified water
Solution Approach 1:
The patent replaces the manual mechanical valve control system with an automatic electronic control system that uses sensors to detect water quality parameters (TDS, temperature, pressure) and automatically adjusts the discharge valve opening degree. This substitution enables precise control while eliminating manual intervention limitations.
Solution Approach 2:
The system implements a feedback control mechanism where sensors continuously monitor water quality parameters and feed this information back to the control unit. The control unit then adjusts the discharge valve accordingly to maintain optimal purified water quality and prevent water waste, achieving both precision and automation.
2Measurement precision
If automatic control system is introduced for concentrated water discharge, then precise control is achieved, but system complexity increases and belongs to primary stage of controllable discharging
Solution Approach 1:
The control unit is designed to perform multiple functions: it processes data from multiple sensors (TDS, temperature, pressure), calculates optimal discharge parameters, controls the discharge valve, and adapts to different water sources and pressure conditions. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The system dynamically adjusts discharge parameters (flow rate, valve opening degree) based on real-time changes in water quality parameters (TDS, temperature, pressure). This adaptive parameter adjustment allows the system to maintain precision across varying conditions without requiring complex fixed-control mechanisms for each scenario.
3Adaptability or versatility
If water purification system operates with varying tap water pressure, then system can adapt to different household conditions, but water production rate becomes unstable and water quality after recovery is unstable
Solution Approach 1:
The system uses pressure sensors to continuously monitor inlet water pressure and feeds this information back to the control unit. The control unit then adjusts the pump power and discharge valve opening degree to compensate for pressure variations, maintaining stable water production rate and quality despite varying tap water pressure conditions.
Solution Approach 2:
The system dynamically adjusts its operating parameters (pump speed, valve opening) in real-time based on detected pressure conditions. This dynamic adaptation allows the system to maintain stable performance across different pressure environments, transforming from a static fixed-parameter system to a dynamic adaptive system.
4Object-generated harmful factors
If concentrated water is discharged with persistent gas or bubbles, then gas removal occurs, but water hammer and liquid hammer generate causing valve core wear and jitter noise
Solution Approach 1:
The system performs preliminary degassing action by adjusting the discharge parameters before gas bubbles can accumulate and cause water hammer. The control unit detects gas presence and adjusts the discharge flow rate to prevent bubble formation and accumulation, eliminating the root cause of water hammer before it occurs.
Solution Approach 2:
The system implements cushioning measures by controlling the discharge flow rate to prevent sudden gas release that causes water hammer. The gradual and controlled discharge of gas bubbles reduces impact forces on the valve core, protecting components from wear and noise before damage can occur.
