Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners have complex structures with a large number of parts, making it difficult to maintain filters and reducing suction efficiency due to dust accumulation, and require disassembly for filter access.
Innovation Solution
A cleaner design featuring a single flow guide that forms both suction and exhaust passages for the suction motor, reducing the number of parts and complexity, allowing for easy filter separation and maintenance, while maintaining airflow efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate structures are provided for guiding air discharged from the cyclone to the motor and for guiding air that has passed the motor to the post motor filter, then the airflow paths are clearly defined, but the number of parts is large and the structure is complicated
Solution Approach 1:
The patent combines the suction passage guide and exhaust passage guide into a single integrated flow guide structure. The flow guide has a first portion that guides air from the cyclone to the motor and a second portion that guides air from the motor to the post motor filter, merging two separate guiding functions into one component. This reduces the number of parts while maintaining clear airflow path definition.
Solution Approach 2:
The flow guide serves multiple functions: it acts as both a suction passage guide and an exhaust passage guide, and also provides structural support for mounting the motor and filters. This multi-functionality reduces the overall number of components needed in the system.
2Strength
If the pre motor filter is disposed between the airflow generator and the cyclone and surrounded by a housing, then the filter is protected, but it is required to disassemble the product to reach the filters for maintenance
Solution Approach 1:
The housing is divided into a main body and a detachable cover portion. The cover can be easily removed to provide direct access to the pre motor filter and post motor filter for maintenance, while the main body remains intact. This segmentation allows the filter to be protected during operation but easily accessible when needed.
Solution Approach 2:
The cover is designed to be dynamically removable and reattachable, transitioning from a closed protective state during operation to an open accessible state during maintenance. This dynamic design allows the system to adapt between protection and accessibility requirements.
3Reliability
If multiple separate components are used for airflow guidance, then each component can be optimized for its specific function, but the overall device size increases and compactness is reduced
Solution Approach 1:
Multiple airflow guidance functions are merged into the single flow guide structure, which has different portions for guiding suction air and exhaust air. This integration maintains functional optimization while reducing the overall device volume by eliminating gaps and interfaces between separate components.
