Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool water filtration systems using quartz sand or non-woven fabrics suffer from poor filtering efficiency due to contaminant accumulation, leading to decreased water flow and potential damage to filter pumps, and are costly and cumbersome to maintain.
Innovation Solution
A filter system incorporating a filter cartridge with a fiber filter material composed of spherical fiber balls, each knotted with a fixing member, providing a high specific surface area and density, which are distributed across multiple chambers to enhance filtration efficiency and reduce maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If quartz sand or non-woven fabric is used as filter media, then the filter structure is simple and cost is low, but filtering effect is poor and contaminant interception efficiency is low
Solution Approach 1:
The patent uses composite filter media consisting of multiple layers with different functions: a non-woven fabric layer for preliminary filtration, an activated carbon layer for adsorption of organic contaminants, and a ceramic layer for fine filtration. This composite structure combines the advantages of different materials to achieve high filtering effect while maintaining reasonable complexity
Solution Approach 2:
The patent employs porous ceramic filter elements with controlled pore sizes and distributions. The porous structure provides large surface area for contaminant interception while maintaining good water flow, resolving the contradiction between filtering effect and structural simplicity
2Productivity
If traditional filter media is used, then initial cost is low, but contaminant accumulation occurs leading to decreased water flow and pump damage
Solution Approach 1:
The patent designs the filter system with easily removable and replaceable filter cartridges. When contaminants accumulate, the entire cartridge can be quickly removed and replaced, restoring water flow without complex cleaning procedures. The system also includes a backwash function to recover and redistribute filter media
Solution Approach 2:
The filter media is divided into multiple separate cartridges that can be independently replaced. Each cartridge contains a specific layer组合, allowing selective replacement based on contamination patterns, thereby maintaining high water flow and interception efficiency
3Ease of operation
If filter media is not replaced frequently, then maintenance cost is low, but accumulated contaminants decrease water flow and damage filter pumps
Solution Approach 1:
The filter system includes automatic monitoring sensors that detect contaminant accumulation and water flow changes. When thresholds are reached, the system automatically initiates backwash cycles or alerts users for cartridge replacement, eliminating the need for frequent manual inspections and maintenance while preserving system performance
Solution Approach 2:
The patent implements a continuous backwash function that periodically cleans the filter media without stopping water filtration. This maintains contaminant interception efficiency and water flow continuously, reducing the frequency and intensity of maintenance operations
