Solution Overview
Problem
Existing washing machines lack effective filtration methods for microfibers, which can contaminate sewage systems and the environment, and current solutions often require unnecessary filtration or lead to premature wear of filtration systems.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If filtration means are continuously activated to filter microfibers from water circulation, then microfiber removal efficiency is improved, but filtration system wear increases and resource consumption rises
Solution Approach 1:
The detecting means analyzes water circulation in advance to determine whether microfibers are present before activating the filtering means. This preliminary detection prevents unnecessary filtration operations, extending the lifetime of the filtration system while ensuring it is activated only when microfibers are actually present in the water.
Solution Approach 2:
The system employs a feedback mechanism where detecting means continuously monitor water circulation for microfiber presence and provide real-time information to the control device. Based on this feedback, the filtering means are activated only when microfibers are detected, optimizing both microfiber removal efficiency and filtration system durability.
2Object-affected harmful factors
If filtration means are continuously activated to filter microfibers, then microfiber removal efficiency is improved, but energy and resource consumption increases
Solution Approach 1:
The detecting means perform preliminary analysis of water circulation to identify microfiber presence before the filtering means are activated. This prevents unnecessary energy consumption during filtration operations when microfibers are not present, while ensuring energy is used effectively only when filtration is actually needed.
Solution Approach 2:
Instead of continuous filtration operation, the system employs periodic activation of the filtering means based on detection results. The filtration operates intermittently only when microfibers are detected in the water circulation, significantly reducing overall energy and resource consumption while maintaining effective microfiber removal.
3Measurement precision
If detection means are installed to identify microfibers in water, then filtration activation precision is improved, but device complexity increases
Solution Approach 1:
The detecting means are integrated into the existing water circulation system of the washing machine, serving multiple functions: detecting microfiber presence, providing feedback for filtration control, and monitoring water quality. This multi-functionality approach improves measurement precision without proportionally increasing device complexity, as the detection system leverages existing infrastructure.

AI summary
A washing machine has a drum, a sump underneath the drum, a water circulation including an extractible drawer for introducing detergent or additives, the water circulation being in fluid connection to detecting means for detecting microfibers or contamination in the water and a circulation pump and pipes for circulating water. A method for its operation comprises the steps of branching off an amount of water circulating in the circulation and transporting it to the detecting means for being analyzed and analyzing the water in the detecting means. Depending on the result of this analysis, a filtering process with filtering means for filtering out the microfibers from the water is activated. The microfibers that have been filtered out can be collected and then removed easily from the washing machine.
