Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to effectively separate and automatically dispose of microplastic waste, particularly microfibers, from wastewater effluent, leading to environmental contamination and cumbersome manual cleaning processes.
Innovation Solution
A compactor system is introduced that extracts and compresses microplastics from waste effluent using a chamber with moveable plates driven by a drive unit, allowing for automatic compression and discharge of the microplastic waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mesh filters are used to stop microfibers, then microfiber collection effectiveness is improved, but the filter clogs quickly causing pressure drop and flow rate reduction
Solution Approach 1:
The filter is divided into multiple layers with different pore sizes. The first layer has larger pores to capture large debris while maintaining high flow rate, the second layer has medium pores for microfiber capture, and the third layer has smaller pores for fine particle filtration. This segmentation allows each layer to perform its specific function without the entire filter clogging quickly.
Solution Approach 2:
The first layer with larger pores performs preliminary filtration of large debris before the effluent reaches the finer filtration layers. This preliminary action prevents large particles from blocking the smaller pores in subsequent layers, thereby maintaining flow rate while still achieving effective microfiber collection.
2Manufacturing precision
If mesh filters with small孔径 are used to stop microfibers, then filtration precision is improved, but the filter clogs quickly and requires frequent manual cleaning
Solution Approach 1:
The multi-layer structure segments the filtration task across layers with progressively smaller pores. The first layer handles large debris, the second layer captures microfibers, and the third layer filters fine particles. This segmentation maintains high filtration precision while distributing the clogging load, reducing the frequency of manual cleaning required.
Solution Approach 2:
The filter cartridge is designed as a disposable component that can be easily replaced. When the filter becomes clogged, the entire cartridge is discarded and replaced with a new one, eliminating the need for manual cleaning operations and reducing maintenance complexity for the user.
3Device complexity
If manual cleaning of filters is required, then device complexity is reduced, but loss of time and user convenience deteriorate
Solution Approach 1:
The filter cartridge is designed as a disposable component. When it becomes clogged or reaches its filtration capacity, the entire cartridge is discarded and replaced with a new one. This approach eliminates the time-consuming manual cleaning process while keeping the overall system relatively simple, as no complex automated cleaning mechanisms are required.
4Productivity
If wastewater is discharged directly after filtration, then productivity is improved, but environmental harm from microplastic release increases
Solution Approach 1:
The multi-layer filtration system segments the water treatment process into distinct stages: coarse filtration, microfiber capture, and fine particle removal. This segmentation enables effective microplastic removal while maintaining high throughput, as each layer processes different size ranges efficiently without creating bottlenecks.
Solution Approach 2:
The system changes the pore size parameter progressively across different layers, from large pores in the first layer to medium pores in the second layer and small pores in the third layer. This parameter change strategy enables the system to achieve high filtration efficiency for microplastics while maintaining adequate flow rates throughout the system.

AI summary
The invention relates to preventing microplastics from entering the environment. The invention is directed to filtering and compacting microplastics from any effluent, but in particular to filtering and compacting microfibers from the wastewater of washing machines and other appliances. However, the invention may also be applied in any industry where microparticles are generated, e.g. the industrial manufacture of textiles, or in treating roadside runoff, or where microparticles are handled, e.g. in Waste Water Treatment Plants. The invention is a compactor for automatically extracting and compressing microplastics from waste effluent, the compactor comprising; a chamber with an inlet; at least one plate within the chamber moveable between a non-compressing position and a compressing position, and a drive unit for driving the at least one plate; and a discharge outlet arranged to allow the automatic discharge of compressed microplastics.
