Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices in drying machines and washing/drying machines require complex, time-consuming, and often ineffective cleaning methods, leading to potential malfunction.
Innovation Solution
A removably mounted filter device with a plate-like filter portion and a disc-like closing element connected by a ribbed structure, allowing easy removal, cleaning, and reinstallation, ensuring effective filtration without interrupting the air flow and condensation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the filter device is integrated permanently into the condenser, then the air flow path is optimized, but the cleaning process becomes complex and time-consuming
Solution Approach 1:
The filter device is divided into separate components: a filter element that can be removed independently from the condenser assembly. This segmentation allows the filter to be cleaned separately without disassembling the entire condenser, resolving the contradiction between maintaining integrated air flow paths and enabling easy cleaning.
Solution Approach 2:
The filter element is extracted as a removable component from the condenser system. A user can remove the filter element for cleaning while the condenser remains in place, thus maintaining the optimized air flow path configuration while enabling simple and quick cleaning operations.
2Ease of operation
If the filter device is made removable for easy cleaning, then the cleaning process is simplified, but the air flow path and condensation process may be interrupted
Solution Approach 1:
The removable filter element is designed with a localized sealing mechanism that maintains the air flow path integrity when installed. The filter element includes gaskets or seals at its edges that ensure proper sealing with the condenser housing, allowing easy removal for cleaning while maintaining air flow continuity during operation.
3Loss of time
If the filter device structure is simplified for easy removal, then the cleaning process is quick, but the filtration effectiveness may be reduced
Solution Approach 1:
The filter element is designed with an asymmetric structure where the filtration surface is optimized for effectiveness while the removal interface is simplified. The filter element has a specific orientation with sealing surfaces on one side and the filtration media on the other, allowing quick removal while maintaining high filtration performance during operation.
