Modular Vacuum Cleaner Nozzle Assembly for Easier Redesign
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of vacuum cleaner nozzles requires significant financial and personnel investments due to the need for constant redesign and adaptation to new functionalities and design requirements, leading to high production costs.
Innovation Solution
A vacuum cleaner nozzle design featuring a connecting part that serves as a holder for both the upper and lower shells, allowing for decoupling and modular functionality, enabling changes in design or functionality without affecting the entire nozzle, with features like detachable fastening and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the upper nozzle shell and lower nozzle shell are directly fastened together to form a complete nozzle, then the structural integrity is maintained, but any design or functionality changes require complete redesign of the entire nozzle
Solution Approach 1:
The nozzle is divided into three separate components: upper nozzle shell, connecting part, and lower nozzle shell. The connecting part serves as an intermediate carrier element that can be independently modified. This segmentation allows changes to be made to individual components without affecting the entire nozzle assembly, thereby improving adaptability while reducing overall redesign complexity.
2Ease of operation
If bearing points are constructed as single integrated components, then the assembly process is simplified, but the assembly of wheel axles becomes complicated
Solution Approach 1:
The bearing points are divided into two separate parts: bearing points provided in the connecting part and counter-bearings provided in the lower nozzle shell. This segmentation allows wheel axles to be simply placed on the lower nozzle shell during assembly, with the bearing encloses them automatically when the connecting part is attached, eliminating complicated assembly procedures while maintaining ease of operation.
3Adaptability or versatility
If all functionalities are integrated into the upper and lower nozzle shells, then the nozzle structure is compact, but modular design and selective replacement are not possible
Solution Approach 1:
The connecting part is identified as a separate carrier element that can serve as a holder for both shells while potentially housing certain functionalities. This creates a modular structure where the upper nozzle shell module can be used for design purposes while functionalities are distributed between the connecting part and lower shell, enabling selective replacement and adaptation without increasing overall complexity.

AI summary
The invention relates to a vacuum cleaner nozzle with a nozzle lower shell (2) functioning as a sliding bottom and with a nozzle upper shell (1) serving as a nozzle housing. In addition, the vacuum cleaner nozzle has a suction fitting (8) connected to the suction channel (10). The suction channel (10) runs between the nozzle upper shell (1) and nozzle lower shell (2). A connecting part (3) is placed between the nozzle upper shell (1) and the nozzle lower shell (2), whereby both the nozzle upper shell (1) as well as the nozzle lower shell (2) can be fastened to said connecting part.
