Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Washing machines with moisture adsorption rotor structures face issues of filter screen clogging, affecting drying efficiency and safety due to lint and impurities, necessitating manual cleaning which is not user-friendly.
Innovation Solution
A clothing treatment device with a detachable access panel covering the air outlet duct allows easy disassembly of the drum driving mechanism and filter screen for manual cleaning, enhancing user convenience and maintaining efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter screen is disposed in the air outlet duct to filter out impurities, then the drying efficiency and safety are improved, but the filter screen becomes clogged after long-term use, affecting the drying effect
Solution Approach 1:
The access panel is designed as a detachable component that can be separated from the housing, allowing users to access and maintain the filter screen without disassembling the entire device. This segmentation of the housing and access panel enables easy maintenance while preserving the filtration function.
Solution Approach 2:
The filter screen is extracted from the internal structure and made accessible through the detachable access panel. Users can remove and clean the filter screen independently without affecting other components, facilitating easy maintenance while maintaining the drying efficiency.
2Ease of repair
If the filter screen is made accessible for manual cleaning, then the ease of maintenance is improved, but the structural complexity of the housing increases
Solution Approach 1:
The housing is segmented into a main body and a detachable access panel. This simple segmentation allows the filter screen to be accessible for cleaning without requiring complex disassembly mechanisms, adding minimal structural complexity while improving ease of repair.
Solution Approach 2:
The access panel is extracted as a separate, detachable component from the housing. This simple extraction design allows users to remove the panel for filter screen cleaning without complicating the overall housing structure, maintaining structural simplicity while enhancing maintainability.
