A washing machine comprising a filtering member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional washing machines discharge significant amounts of fibers into waste water, contributing to environmental pollution, and their filters clog quickly due to fiber accumulation, necessitating frequent cleaning or replacement.
Innovation Solution
A washing machine with a filtering member featuring a sponge-like additional filter positioned at a distance from the water inlet, inclined in the receptacle, and supported by a frame, which retains fibers effectively while allowing water flow, using a porous material with varying pore sizes and antimicrobial properties to prevent clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mesh filter is used to filter washing water, then filtration performance is improved, but the filter surface gets clogged quickly due to fiber accumulation
Solution Approach 1:
The filter system is divided into two distinct components: a mesh filter for initial filtration and a sponge filter for secondary fiber capture. This segmentation allows each component to perform its specific function efficiently, with the sponge filter collecting fibers that would otherwise clog the mesh filter, thereby extending the mesh filter's service life while maintaining filtration performance.
Solution Approach 2:
The sponge filter acts as an intermediary component between the washing water and the mesh filter. It captures floating fibers in the water before they reach the mesh filter surface, preventing direct accumulation on the mesh filter and reducing clogging frequency while maintaining effective filtration.
2Reliability
If a filter is positioned close to the water inlet for effective filtration, then filtration efficiency is improved, but fiber accumulation in front of the inlet increases causing clogging
Solution Approach 1:
The sponge filter is positioned at a specific location within the filter housing, away from the water inlet, creating different functional zones. The area near the inlet remains clear for efficient water intake, while the sponge filter in the downstream area captures fibers, thus maintaining filtration efficiency without blocking the inlet.
Solution Approach 2:
Instead of placing the filter material directly at the inlet (one-dimensional blocking), the sponge filter is positioned in the water flow path downstream from the inlet, utilizing the three-dimensional space within the filter housing. This dimensional arrangement allows water to flow freely into the filter while fibers are captured in the sponge material downstream.

Function Achieved in This Case
The solution increases filtration performance and extends the economic life of the filter by reducing fiber accumulation on the mesh filter, enhancing the retention of larger fibers and preventing microbial contamination.
Implementation Method 1
at least one additional filter which is disposed in the receptacle at a distance from the water inlet for retaining fibers floating in the receptacle
Implementation Method 2
