Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional filtration systems are used to capture microplastics, then microplastic removal efficiency is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The filtration system is divided into multiple filter units with different mesh sizes (e.g., 5-10 microns for microplastics, 20-50 microns for lint). Each filter unit targets specific particle sizes, allowing the system to capture various contaminants effectively while keeping individual filter components simple and manageable.
Solution Approach 2:
The patent employs porous filter materials with specific mesh sizes to capture microplastics. The porous structure allows water to pass through while trapping particles based on size, providing effective filtration without requiring complex mechanical components or high-energy processes.
2Object-affected harmful factors
If advanced filtration systems with multiple stages are implemented, then microplastic capture efficiency is improved, but ease of operation deteriorates
Solution Approach 1:
Filter units are designed as separate, modular components that can be independently removed and cleaned. This segmentation allows users to access and maintain each filter without disassembling the entire washing machine, significantly improving ease of operation despite having multiple filtration stages.
Solution Approach 2:
The filter units are designed to be easily removable by users for cleaning and maintenance without requiring professional service. The simple modular design enables homeowners to perform their own filter maintenance, reducing operational complexity despite advanced filtration capabilities.
3Ease of manufacture
If captured microplastics are disposed of in landfills, then disposal simplicity is improved, but environmental harm increases due to leaching
Solution Approach 1:
Instead of simply discarding microplastics in landfills, the system recovers them through filtration and enables reuse. The captured microplastics can be collected, processed, and reintegrated into manufacturing processes, eliminating landfill disposal and its associated leaching problems while maintaining operational simplicity.
Solution Approach 2:
The patent converts the harmful waste stream of microplastics into a valuable resource for reuse. By capturing and recovering microplastics from washing machine effluent, the system transforms an environmental pollutant into reusable material, eliminating landfill disposal needs and converting a harmful byproduct into an economic asset.
4Device complexity
If microplastics are not captured and reused, then system simplicity is maintained, but loss of substance increases
Solution Approach 1:
The system implements recovery of microplastics through filtration, preventing their loss to the environment. The captured microplastics are collected and can be reused in manufacturing, transforming a waste stream into a recoverable resource while maintaining relatively simple system architecture through modular filter design.
Solution Approach 2:
The patent converts microplastic waste, which would otherwise be an environmental harm, into a beneficial reusable resource. By implementing filtration and recovery systems, the system transforms pollution into valuable material that can be reintegrated into production cycles, reducing both waste and environmental impact.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The proposed system effectively captures and recycles microplastics, reducing their environmental impact by minimizing leaching from landfills and promoting the reuse of reclaimed materials, thus contributing to a more sustainable and circular economy.
Implementation Method 1
The filter unit may be made of multiple screens or meshes of different sizes, configurations, and/or materials that work together to capture microplastics and other particles from the water
Implementation Method 2
The processor may then physically break down the filter unit into smaller and smaller particles through a combination of methods including but not limited to: chopping, shredding, grinding, crushing, or pulverizing
Implementation Method 3
The processor may then melt the particles and reform them into a new filter unit or another useful product

AI summary
A closed loop system for and method of capture, recycling, and safe disposal of microplastics, applied to residential and commercial textile washing and drying machine devices is proposed. The closed loop system allows for effective capture, processing and recycling, or safe disposal of microplastic material. The system employs an easy-to-use filter design, optimized to capture microplastics within the device or through air or water discharge lines, followed by post-processing of filter devices where the captured microplastic residue is physically or chemically processed for either recycling the captured microplastic residue into new filters or new products, or alternatively the captured microplastic residue can be locked into a safe matrix for disposal, wherein leaching from landfills into the environment is minimized or eliminated.
