Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current filter devices in clothes dryers are time-consuming and laborious to clean, and they often fail to completely remove debris from the filter screen, especially from the small meshes, leading to bacterial growth and incomplete filtration.
Innovation Solution
A filter screen component with a motor and an annular filter screen body having multiple meshes, where the filter screen is connected to a rotary shaft of the motor, allowing debris to be removed by centrifugal force without the need for manual cleaning or additional cleaning components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning of the filter screen is performed, then debris can be removed, but it is time-consuming and laborious
Solution Approach 1:
The filter screen performs self-cleaning by rotating under the action of airflow. The airflow generated by the air duct blows debris off the filter screen surface, and the rotation ensures all areas are cleaned without manual intervention. This eliminates the need for separate cleaning operations and reduces both time and labor requirements.
Solution Approach 2:
The filter screen transitions from a static component to a dynamic rotating component. By connecting the filter screen to a motor-driven rotary shaft, it can rotate automatically during operation, enabling continuous self-cleaning functionality and improving cleaning efficiency while reducing manual labor.
2Extent of automation
If a cleaning component is added to mechanically clean the filter screen, then debris removal is automated, but the cleaning component cannot access debris in small meshes and debris builds up on the cleaning component
Solution Approach 1:
The invention removes the problematic cleaning component from the system and replaces it with a self-cleaning mechanism using airflow. By extracting the mechanical cleaner, the patent avoids the issues of debris buildup on the cleaner and incomplete cleaning of mesh areas, while achieving automation through the motor-driven rotation and airflow system.
Solution Approach 2:
The invention uses airflow (pneumatic action) instead of mechanical contact to clean the filter screen. The air duct generates airflow that blows debris off the filter screen during rotation, effectively reaching areas that mechanical components cannot access and preventing debris buildup on cleaning elements.
3Ease of operation
If the filter screen rotates to enable self-cleaning, then cleaning becomes automatic and thorough, but the device complexity increases
Solution Approach 1:
The motor-driven rotary shaft serves multiple functions: it rotates the filter screen for self-cleaning, enables airflow generation for debris removal, and integrates with the existing filtration system. This multi-functionality reduces the need for separate dedicated cleaning mechanisms, thereby limiting the increase in device complexity.
Solution Approach 2:
The invention merges the filtration function and cleaning function into a single integrated system. The filter screen rotation mechanism is combined with the airflow generation system, allowing both filtration and self-cleaning to occur during normal operation without requiring separate independent systems.
4Extent of automation
If mechanical cleaning components are used, then automated cleaning is achieved, but debris is transferred to the cleaning component and breeds bacteria
Solution Approach 1:
The invention uses airflow to remove debris from the filter screen during rotation, eliminating the need for mechanical cleaning components that would contact and retain debris. The airflow carries debris away through the air duct, preventing debris accumulation and subsequent bacterial growth on cleaning surfaces.
Solution Approach 2:
By removing mechanical cleaning components from the system and replacing them with an airflow-based self-cleaning mechanism, the patent eliminates the source of debris transfer and bacterial growth problems associated with mechanical cleaners while maintaining automated cleaning functionality.
