Vacuum cleaner floor nozzle assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaner floor nozzles face challenges in adapting to various floor types due to limited adjustment options and increased material and production costs with specialized nozzles, while existing adjustable nozzles require disproportionate technical effort and are inefficient in handling different floor coverings, especially when suction power is low.
Innovation Solution
A vacuum cleaner floor nozzle arrangement with detachable lower parts of different geometries that can be exchanged to form multiple configurations, allowing for extensive adaptation of the nozzle's geometry and design without the need for multiple nozzles, including features like slide-on bevels and rotatable support elements for efficient cleaning on diverse surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple specialized vacuum cleaner nozzles are manufactured for different floor types, then cleaning effectiveness on specific floor coverings is improved, but material costs and storage requirements increase significantly
Solution Approach 1:
The nozzle is divided into a housing and multiple interchangeable lower parts (first lower part, second lower part), each with different geometries and functions. This segmentation allows users to attach only the specific lower part needed for the current floor type, reducing the number of complete nozzles to store while maintaining versatility across different cleaning surfaces.
Solution Approach 2:
The housing is designed as a universal component that can accommodate multiple types of lower parts with different geometries. This multi-functionality allows a single housing to serve various cleaning purposes by simply changing the attached lower part, eliminating the need for multiple complete nozzles and reducing storage requirements.
2Adaptability or versatility
If adjustable functional groups are added to the nozzle to adapt to different floor coverings, then versatility is improved, but device complexity and technical effort increase disproportionately
Solution Approach 1:
The nozzle incorporates movable functional groups including sealing elements and support elements that can be adjusted between lowered and raised positions. This dynamic capability allows the nozzle to adapt to different floor contact requirements without complex mechanical adjustment mechanisms, as the elements can be easily repositioned to control floor contact and shape the suction air flow.
3Adaptability or versatility
If the suction mouth geometry is significantly varied for different applications, then cleaning performance on specific surfaces is improved, but manufacturing complexity and production costs increase
Solution Approach 1:
The suction mouth geometry is integrated into the interchangeable lower parts rather than the main housing. This segmentation allows different suction mouth geometries to be manufactured as separate, optimized components that can be attached to a standard housing, simplifying the manufacturing process while maintaining the ability to vary suction mouth shape for different cleaning applications.

AI summary
The invention relates to a vacuum cleaner floor nozzle assembly comprising a housing (1) with a suction channel (3) connected to a suction air duct and a first lower part (4a) arranged on the underside of the housing (1) and comprising a first sliding base (5a) and a suction nozzle (6a) connected to the suction channel (3). According to the invention, the first lower part (4a) is detachably connected to the housing (1) to form a vacuum cleaner floor nozzle in a first configuration. The vacuum cleaner floor nozzle assembly further comprises a second lower part (4b) with a second sliding base (5b) and with a suction nozzle (6b). The second lower part (4b) has a different geometry compared to the first lower part (4a) and can be detachably attached to the housing (1) in exchange with the first lower part (4a) to form a vacuum cleaner floor nozzle in a second configuration.
