Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multistage fiber filtering systems require large installation spaces and high costs due to the need for multiple filters and stages, and they often filter raw water unnecessarily, wasting resources and increasing maintenance needs.
Innovation Solution
A multistage fiber filtering apparatus with adjustable filtration modes based on turbidity, using fiber yarn and fiber ball media, where raw water can be filtered through one, both, or neither medium depending on turbidity measurements, optimized by a turbidity meter and controller to reduce unnecessary filtration and resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple filters and stages are arranged in the same filtration tank to improve treating speed and water quality, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple filtering functions into a single integrated filtration tank. The first and second filtering layers with different pore sizes are arranged vertically within one tank, allowing multi-stage filtration to be performed in a single device rather than requiring separate filters and tanks. This merging approach improves treating speed while controlling device complexity.
Solution Approach 2:
The filtration system is segmented into multiple filtering layers with different pore sizes (first filtering layer with larger pores, second filtering layer with smaller pores) arranged in sequence. This segmentation allows water to undergo progressive filtration stages within a single tank, achieving improved water quality and treating speed without requiring multiple separate filtration devices.
2Reliability
If raw water is filtered through all fiber media to improve water quality, then purity is improved, but loss of substance increases due to unnecessary filtration
Solution Approach 1:
The patent implements dynamic control of the filtration process based on raw water quality. A turbidity detection device continuously monitors incoming water, and a control device adjusts the filtration mode accordingly: using only the first filtering layer for clear water, both layers for moderately turbid water, or bypassing filtration for highly turbid water. This dynamic adjustment ensures water quality requirements are met while minimizing unnecessary resource consumption.
Solution Approach 2:
The system changes operational parameters (which filtering layers are activated) based on the turbidity parameter of incoming water. When turbidity is low, only the first filtering layer is used; when turbidity increases, the second filtering layer is engaged; when turbidity is very high, filtration is bypassed. This parameter-based control optimizes the balance between water quality and resource efficiency.
3Productivity
If a plurality of filters are used to improve treating speed, then productivity is improved, but installation space increases
Solution Approach 1:
The patent merges multiple filtering functions into a single vertical filtration tank structure. Instead of installing multiple separate filtration devices that would require significant horizontal space, the system stacks filtering layers vertically within one compact tank, achieving multi-stage filtration capability while minimizing installation footprint.
Solution Approach 2:
The patent transitions from a horizontal arrangement of multiple filters to a vertical arrangement within a single tank. The first and second filtering layers are stacked vertically, with water flowing downward through each layer in sequence. This dimensional change from horizontal to vertical configuration achieves multi-stage filtration without increasing installation space.

AI summary
The present invention relates to a multistage fiber filtering apparatus capable of selectively filtering depending on turbidity of raw water, in which a first filtration mode where the raw water passes through a fiber ball medium, a second filtration mode where the raw water passes through a fiber yarn medium, or a third filtration mode where the raw water passes through both of the fiber yarn medium and the fiber ball medium may be selectively operated.
