Dual Suction Vacuum Cleaner for Sonic and Mechanical Beaters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners are ineffective in removing deeply embedded dirt from carpets due to limitations in both mechanical and sonic beaters, which can damage surfaces and fail to efficiently collect loosened debris, especially when relying on a single suction inlet.
Innovation Solution
A vacuum cleaner design featuring dual suction inlets, one associated with a mechanical beater and another with a sonic beater, allowing for efficient collection of dirt and debris loosened by the sonic beater, thereby improving cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single suction inlet is used for both mechanical and sonic beaters, then the device complexity is reduced, but the cleaning efficiency decreases because dirt loosened by the sonic beater cannot be effectively collected
Solution Approach 1:
The suction system is segmented into two separate suction inlets: one associated with the mechanical beater and another with the sonic beater. This segmentation allows each beater type to have its own dedicated suction path, enabling the sonic beater to effectively collect loosened dirt particles while the mechanical beater handles surface debris, thereby resolving the contradiction between cleaning efficiency and device complexity.
2Productivity
If mechanical beaters are used to dislodge ingrained dirt particles, then the effectiveness in loosening dirt improves, but the surface damage increases
Solution Approach 1:
The cleaning function is segmented between two separate beater systems: mechanical beaters for surface-level dirt removal and sonic beaters for deeply ingrained particles. This segmentation allows each system to operate in its optimal performance range, with sonic beaters handling embedded dirt without causing surface damage while mechanical beaters manage surface debris, thus resolving the contradiction between dirt dislodging effectiveness and surface damage.
Solution Approach 2:
The sonic beater utilizes high-frequency mechanical vibrations to dislodge deeply ingrained dirt particles from carpet fibers without requiring direct physical contact that would cause surface damage. The vibrational energy penetrates the carpet pile to loosen embedded particles, which are then removed by the dedicated suction inlet, resolving the contradiction between effective dirt removal and surface protection.
3Object-affected harmful factors
If sonic beaters are used to avoid surface damage, then the surface protection improves, but the effectiveness in dislodging surface dirt decreases
Solution Approach 1:
The beater system is segmented into two specialized components: sonic beaters optimized for deeply ingrained particles and mechanical beaters optimized for surface-level dirt. This segmentation allows the mechanical beater to handle surface dirt removal efficiently while the sonic beater protects the surface, resolving the contradiction between surface protection and surface dirt removal effectiveness.

AI summary
A vacuum cleaner includes a base, and a mechanical beater and a vibrating member connected thereto. A first suction inlet in the base is associated with the mechanical beater. A second suction inlet in the base is associated with the vibrating member. An airflow path is in fluid communication with the first and second suction inlets and flows to a debris collector.
