Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods are ineffective in collecting microplastics once they have entered waterways, as they cannot be netted without harming wildlife and denser microplastics sink to the ocean depths, rendering filtration techniques obsolete.
Innovation Solution
Integrating magnetic particles into plastic and rubber products during manufacturing, allowing for the collection of microplastics using magnetic components, which can be strategically placed in areas prone to degradation and waste collection sites to capture and remove microplastics without harming aquatic life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional filtration and netting methods are used to collect microplastics from waterways, then collection capability is improved, but harm to aquatic wildlife increases and collection efficiency decreases due to sinking microplastics
Solution Approach 1:
Magnetic particles are integrated into plastic and rubber products during the manufacturing process before the products are deployed. This preliminary action ensures that when the products degrade into microplastics, the magnetic particles are already embedded, enabling subsequent magnetic collection without harming wildlife
Solution Approach 2:
The patent replaces traditional mechanical collection methods (netting, filtration) with a magnetic field-based collection system. Magnetic collectors use magnetic fields to attract and collect microplastics containing magnetic particles, eliminating the need for physical nets and filters that harm aquatic life
2Productivity
If magnetic particles are integrated into plastic products during manufacturing, then microplastic collection becomes feasible and effective, but product manufacturing complexity increases
Solution Approach 1:
The patent combines magnetic particles with plastic and rubber materials during the existing manufacturing processes. This merging approach integrates the magnetic functionality into the product without requiring separate manufacturing steps, thereby minimizing additional complexity while enabling effective magnetic collection

Function Achieved in This Case
Effectively reduces the pervasion of microplastics in the environment by enabling the collection and recycling of microplastics from runoff water, minimizing ecological disruption and allowing for the controlled removal of microplastic pollutants from plastic and rubber items.
Implementation Method 1
Magnetic particles can be used in household items like plastic bottles, straws, utensils, and containers. The present invention is a system and method for creating and collecting magnetic microplastics that effectively combines magnetic material with plastics during their manufacture
Implementation Method 2
Magnetic collectors can be placed at drains and scuppers in the roadways, ditches, canals, spillways, bridge pillars and buoys in lakes, rivers and oceans. Magnetic collectors can further be trawled behind vessels in lakes, rivers, and oceans with minimal danger to animal and plant life

AI summary
A system and method for creating and collecting magnetic microplastics effectively combines magnetic material with plastics during their manufacture, thereby producing microplastics that can be easily collected via removal devices equipped with magnetic components. Magnetic particles are mixed with plastic/rubber resins during manufacturing of tires, roofing materials, and other plastic items. The magnetic particles can be made from natural or artificial magnets. After mixing, the partially-magnetic rubber/plastic result can be applied to areas of the manufactured plastic item that have the highest propensity to degrade into microplastic pollutants. For example, the thread of a tire, where friction with the road causes most of the wear, is an optimal location for integration of magnetic particles. When the plastics break down into microplastics, the microplastics can then be collected with magnets. The collected microplastics can then be removed from the magnetic collectors during routine maintenance and subsequently recycled safely.
