Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Swimming pools with in-floor cleaning systems face high energy consumption due to the need for powerful pumps and extensive plumbing, which increases operational costs and energy usage, despite efforts to improve efficiency through more efficient motors and timers.
Innovation Solution
The implementation of a cam-operated multiport distribution valve that minimizes concurrent flow through adjacent outlets and maximizes pressure duration to popup heads, combined with venturi-enhanced flow and ozone generation, to enhance cleaning efficiency and reduce energy usage by optimizing pump operation and flow distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If powerful pumps and extensive plumbing are used for in-floor cleaning systems, then cleaning effectiveness is improved, but energy consumption increases
Solution Approach 1:
The patent implements a dynamic flow distribution system using a multiport distribution valve that sequentially directs water flow to different groups of in-floor cleaning heads. This dynamic switching allows the system to achieve effective cleaning coverage while using a single pump at lower power settings, as water is delivered intensively to one section at a time rather than continuously to all sections simultaneously.
Solution Approach 2:
The patent divides the pool floor cleaning system into multiple segments or zones, each served by a separate outlet from the distribution valve. By segmenting the cleaning area and activating different segments sequentially through the rotating valve mechanism, the system reduces the total simultaneous water flow requirement, enabling effective cleaning with lower pump power and reduced energy consumption.
2Use of energy by moving object
If pump run time is reduced to save energy, then energy consumption decreases, but cleaning effectiveness may be compromised
Solution Approach 1:
The patent ensures continuous cleaning action throughout the pool by implementing a rotating multiport distribution valve that sequentially activates different groups of cleaning heads. As one group completes its cleaning cycle, the valve rotates to activate the next group, maintaining uninterrupted cleaning coverage across the entire pool floor. This continuous sequential operation allows reduced overall run time while maintaining cleaning effectiveness.
Solution Approach 2:
The system employs periodic activation of cleaning head groups through the rotating distribution valve. Each group of cleaning heads receives intensive water flow for a specific duration, then becomes inactive while the valve rotates to the next group. This periodic on-off cycling across different zones enables energy reduction through decreased total run time while maintaining effective cleaning through repeated targeted action on each section.
