Proportional Water Control System for Smooth Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for recreational water bodies like swimming pools and hot tubs lack the ability to continuously monitor and adjust water characteristics such as temperature, pH, and microorganism levels in real-time, often requiring abrupt changes that can disrupt water circulation and fail to maintain optimal safety and comfort levels.
Innovation Solution
A control system that includes sensors to monitor water characteristics and a valve system to adjust dispensing rates of additives and energy inputs, allowing for continuous, proportional control of water parameters without shutting off the flow, enabling on-the-go maintenance of safe and comfortable water conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional control systems are used to adjust water characteristics, then water parameters can be changed, but the adjustments are abrupt and disrupt water circulation
Solution Approach 1:
The control system dynamically adjusts the dispensing rate of additives and energy inputs in real-time based on sensor feedback, allowing continuous proportional control rather than fixed on/off states. This dynamic adjustment mechanism enables smooth changes in water characteristics without abrupt disruptions to water circulation.
Solution Approach 2:
The system continuously monitors water characteristics through sensors and uses this feedback to automatically adjust the dispensing rate of additives and energy inputs. This closed-loop feedback control ensures that water parameters are maintained within optimal ranges while preventing abrupt changes that would disrupt circulation.
2Reliability
If on-the-go monitoring and control is implemented, then water characteristics can be maintained within optimal ranges, but system complexity increases
Solution Approach 1:
The control system is designed to handle multiple water characteristics (temperature, pH, microorganism levels, etc.) through a single integrated control mechanism that adjusts both additive dispensing and energy inputs. This multi-functional approach maintains reliable water quality control while avoiding the need for separate complex control systems for each parameter.
Solution Approach 2:
The system automatically monitors and adjusts water characteristics without requiring manual intervention. Sensors continuously detect water parameters and the control system autonomously modifies additive dispensing rates and energy inputs, making the system self-regulating and reducing the need for complex external control mechanisms.
3Adaptability or versatility
If proportional control of dispensing rates is used, then water parameters can be continuously adjusted, but control system complexity increases
Solution Approach 1:
The system controls water characteristics by continuously varying the dispensing rate parameter of additives and energy inputs rather than using discrete on/off control. This parameter-based approach enables proportional adjustment of water parameters while using relatively simple valve mechanisms that modulate flow rates based on control signals.
