Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaners face limitations in filtration capacity due to the volume of the storage space for foreign matters, with accumulated dust on filters reducing airflow rates and filtration efficiency.
Innovation Solution
The cleaner design includes a housing divided into two spaces with a separator using centrifugal force to separate foreign matters, and filters with multiple communicating openings and chamber forming portions to maximize filtration capacity and ease of cleaning, allowing all filter faces to function effectively even when dust accumulates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the volume of storage space for foreign matters is increased, then the filtration capacity of the cleaner is improved, but the airflow rate through the fan is reduced due to increased flow path resistance
Solution Approach 1:
The filter assembly is segmented into multiple filtering chambers (first, second, third chambers) with multiple filter faces, allowing air to flow through multiple parallel paths simultaneously. This segmentation increases total filtration capacity without requiring a single large filter that would create excessive flow resistance.
Solution Approach 2:
The filter assembly utilizes three-dimensional spatial arrangement with filter faces positioned at different orientations (front, rear, left, right sides). By arranging filter faces in multiple dimensions and orientations, the design maximizes filtration surface area within the available space while maintaining adequate airflow channels.
2Quantity of substance
If the filtration capacity is increased through larger filters, then more foreign matters are removed, but the flow path resistance increases and reduces the flow rate of air to the fan
Solution Approach 1:
The filtering function is divided into multiple independent chambers and filter faces. Each chamber handles a portion of the airflow, distributing the filtration load across multiple parallel paths rather than forcing all air through a single large filter, thereby reducing flow path resistance while maintaining high filtration capacity.
Solution Approach 2:
The filter assembly structure serves multiple functions simultaneously: it provides multiple filtering surfaces for high capacity, creates multiple parallel airflow paths to reduce resistance, and integrates with the housing to define both filtration and storage spaces. The same structural elements achieve both filtration and airflow management goals.
3Quantity of substance
If a single large filter is used to maximize filtration capacity, then storage space volume is overcome, but the filter becomes difficult to clean and maintain
Solution Approach 1:
The filter assembly is divided into multiple detachable filter faces and filtering chambers. When cleaning is needed, individual filter faces can be removed and cleaned separately, or entire chambers can be accessed independently. This segmentation makes maintenance much easier compared to a single large filter that would require complete disassembly or specialized cleaning equipment.
Solution Approach 2:
The filter assembly is designed with movable and detachable components that can be easily accessed, removed, and repositioned. The filtering chambers can be opened and filter faces detached for cleaning, then reassembled. This dynamic design allows flexible maintenance operations without requiring complete system disassembly.
