Dual-Filter Vacuum Airflow Switching for Continuous Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuuming devices require significant housing space and incur idle time due to the need for separate suction motors and sequential filter cleaning, which disrupts the vacuuming process.
Innovation Solution
A compact vacuuming device design with a single suction motor and valve devices for each filter, allowing immediate filter cleaning without shutting off the suction motor, enabling continuous operation and alternating filter use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple suction motors are used to maintain continuous vacuuming during filter cleaning, then vacuuming continuity is improved, but device complexity and housing size increase
Solution Approach 1:
The system segments the airflow path using valve devices associated with each filter, allowing individual filters to be isolated for cleaning while maintaining operation of the single suction motor. This segmentation enables one filter to be cleaned without affecting the overall vacuuming function.
Solution Approach 2:
The valve devices are pre-positioned to control airflow paths, allowing immediate redirection of air flow to alternative filters when cleaning is required. This preliminary setup enables instant switching without system reconfiguration during cleaning operations.
2Ease of operation
If the suction motor is shut down for filter cleaning, then cleaning can be performed, but idle time occurs disrupting vacuuming operation
Solution Approach 1:
The suction motor operates continuously throughout both vacuuming and cleaning operations. The valve devices redirect airflow dynamically, ensuring the motor's useful action continues uninterrupted while filters are cleaned, eliminating idle time and maintaining constant vacuum generation.
Solution Approach 2:
The valve devices dynamically adjust airflow paths based on operational needs, switching between vacuuming mode and cleaning mode without shutting down the motor. This dynamic control allows the system to adapt its configuration in real-time, maintaining motor operation while enabling filter access.
3Volume of stationary object
If a single suction motor is used to reduce housing size, then compactness is improved, but the ability to maintain continuous vacuuming during filter cleaning deteriorates
Solution Approach 1:
The airflow system is segmented into multiple controllable paths using valve devices, allowing a single suction motor to serve multiple functions. During cleaning, the valve redirects airflow through alternative filters, maintaining the motor's productivity while enabling maintenance operations.
Solution Approach 2:
The single suction motor performs multiple functions: vacuuming during normal operation and maintaining airflow during filter cleaning. The valve devices enable this multi-functionality by dynamically routing airflow, allowing one motor to sustain continuous productivity across different operational states.

AI summary
A vacuuming device has a housing having an air intake and at least one air outlet opening. A suction motor is arranged in the housing. At least two filters are arranged in the housing and each has a flow passage to the suction motor, wherein dirty air sucked into the housing by the suction motor passes through the at least two filters and exits through the at least one air outlet opening. The at least two filters each are provided with a cleaning device and a valve device adapted to close off the flow passage to the suction motor, respectively, as needed.
