Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clothing drying apparatuses face issues with ineffective lint filtration and collection, leading to frequent cleaning needs and reduced user experience due to limited filtering areas and cumbersome designs.
Innovation Solution
A clothing drying apparatus with a filter device featuring an annular filter member, lint cleaning member, and lint collecting member, where the annular filter member rotates with the drying drum, allowing for efficient lint filtration and collection, and the lint cleaning and collecting members are strategically placed on the front support mechanism to improve usability and reduce maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lint filter screen is provided in the air duct, then lint can be filtered out and collected, but the filtering area is limited and the filter screen becomes full quickly requiring frequent cleaning
Solution Approach 1:
The patent transitions from a flat, two-dimensional filter screen to a three-dimensional annular filter structure with hollow interior space. This dimensional change dramatically increases the filtering surface area while providing internal cavities for lint collection, allowing the filter to handle more lint before requiring cleaning and improving overall filtering effectiveness.
Solution Approach 2:
The annular filter structure incorporates a hollow interior space that contains lint collecting cavities within the filter body itself. This nesting approach allows lint to be collected inside the filter structure during rotation, eliminating the need for separate external collection mechanisms and reducing cleaning frequency.
2Reliability
If a lint collecting cavity is formed on the door glass, then lint can be collected, but the door glass weight increases making it difficult to open and close
Solution Approach 1:
The patent extracts the lint collection function from the door glass structure and relocates it to the annular filter assembly mounted on the front support mechanism. This separation removes the weight burden from the door glass while maintaining effective lint collection capabilities through the annular filter's internal cavities.
Solution Approach 2:
The lint collection functionality is copied from the door glass concept to the annular filter structure, which provides the same lint collection purpose without adding weight to the door assembly. The annular filter's hollow interior serves as the lint collecting cavity, achieving the same function in a different location.
3Reliability
If a lint collecting cavity is formed on the door glass, then lint can be collected, but the user cannot observe the drying situation through the door glass
Solution Approach 1:
The lint collection function is extracted from the door glass and relocated to the annular filter assembly on the front support mechanism. This extraction preserves the door glass's transparency and observational function while maintaining effective lint collection through the annular filter's internal cavities.
4Reliability
If the annular filter member rotates with the drying drum, then lint filtration is improved, but the device complexity increases
Solution Approach 1:
The patent merges the rotation drive of the annular filter with the existing drying drum rotation system. The annular filter is driven to rotate together with the drying drum through their mechanical connection, eliminating the need for a separate drive mechanism and reducing overall system complexity while maintaining improved filtration efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
