Swimming Pool Filter Clogging Detection via Flow Rate Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filtration units for swimming pools face challenges in detecting clogging of filters, particularly in woven material filters, as pressure sensors are costly and ineffective due to lack of pressure variations, and existing solutions fail to accurately differentiate between unclogged and clogged states.
Innovation Solution
A filtration unit equipped with a flow rate sensor system that measures water flow differences between unclogged and clogged filters, using a control module to determine clogging levels and states through flow rate measurements, and communicates this information to monitoring devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pressure sensor is used to detect filter clogging, then the clogging detection capability is improved, but the cost increases significantly and the sensor becomes ineffective for woven material filters due to lack of pressure variations
Solution Approach 1:
The patent replaces the mechanical pressure sensor system with a flow rate measurement system. Instead of measuring pressure variations (which are insufficient for woven material filters), the system measures flow rate using a flow meter or velocity sensor, providing effective clogging detection without the limitations of pressure-based methods.
Solution Approach 2:
The patent changes the measurement parameter from pressure to flow rate. By measuring the flow rate of water through the filter and comparing it to reference values, the system can detect clogging levels effectively for woven material filters where pressure variations are not sufficient.

3Ease of manufacture
If flow rate measurement is used to detect filter clogging, then the cost is reduced and detection effectiveness for woven material filters is improved, but additional components (suction pipe, outlet pipe, sensor) are required
Solution Approach 1:
The patent integrates the flow rate sensor into the existing filtration system's water flow path. The suction pipe and outlet pipe are positioned to measure flow through the filter, allowing the same measurement system to serve both flow monitoring and clogging detection functions, reducing overall system complexity despite adding measurement capabilities.
