Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners face challenges in achieving high suction power, compact design, and low noise levels simultaneously.
Innovation Solution
The design incorporates two suction units arranged next to each other and at the same height as the filter device, with a common exhaust air space and straight exhaust air ducts, a flat pleated filter, and a filter cleaning device, along with insulating materials to minimize noise and enhance compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple suction units are added to increase suction power, then the suction power is improved, but the device complexity and noise level increase
Solution Approach 1:
Multiple suction units are merged into a common housing structure with shared exhaust air space and common filter device, reducing overall structural complexity while maintaining high suction power through combined operation of multiple units
2Power
If multiple suction units are added to increase suction power, then the suction power is improved, but the noise level increases
Solution Approach 1:
Exhaust air from multiple suction units is merged into a common exhaust air space that is acoustically insulated from the housing, allowing noise from multiple units to be contained and redirected through controlled exhaust openings rather than propagating directly to the environment
3Volume of moving object
If a compact design is implemented, then the device size is reduced, but the space for exhaust air discharge and filter placement is limited
Solution Approach 1:
The exhaust air space is positioned in the vertical dimension above the suction units, utilizing vertical space rather than horizontal space, allowing compact horizontal footprint while providing adequate volume for exhaust air discharge and filter placement

Implementation Method 1
with the help of which the dirt collection container can be subjected to negative pressure. This allows suction material to be picked up from a surface
Implementation Method 2
The suction air sucked in by the dirt collection container can be filtered by means of the filter device
Implementation Method 3
the at least one suction unit is flow-connected via at least one exhaust air duct to at least one exhaust air opening
