Vacuum Cleaner Nozzle with Removable Plate for Adjustable Suction Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaner nozzles lack versatility in adapting to varying cleaning conditions, such as different surface types and cleaning depths.
Innovation Solution
A removable plate with adjustable attachment options is integrated into the nozzle, allowing for modification of the suction area by changing the size and shape of the suction area, enabling concentrated or gentle cleaning effects depending on the surface, with features like inclined surfaces and varying wall angles to enhance deep cleaning or reduce suction area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the suction area is reduced by attaching a removable plate, then the cleaning effect on a smaller area is strengthened, but the cleaning width is reduced
Solution Approach 1:
The suction area is segmented into multiple zones by dividing the floor interface into a first area with a first suction opening and a second area with a second suction opening. The removable plate can selectively cover one or both openings, allowing the user to segment the suction area according to cleaning needs. This enables concentrated cleaning power on smaller areas while preserving the option for wider cleaning when both openings are exposed.
Solution Approach 2:
The removable plate is designed to be dynamically attachable and detachable, allowing the suction area configuration to change based on cleaning requirements. The plate can be positioned to cover the first opening, second opening, or both, providing dynamic adjustment of the cleaning width and power concentration without permanent structural changes to the nozzle.
2Power
If the removable plate is made to provide deep cleaning effect with inclined surfaces, then the cleaning effectiveness on rugs is improved, but the device complexity increases
Solution Approach 1:
The removable plate incorporates local quality variations through inclined surfaces and different thickness regions. The plate has a first region with a first inclination angle and a second region with a second inclination angle, creating localized pressure distribution patterns. This allows the plate to apply targeted pressure on rug surfaces for deep cleaning effectiveness without requiring complex mechanical mechanisms, achieving enhanced cleaning power through geometric design alone.
