Solution Overview

Problem

Existing vacuum cleaner nozzle systems are limited in their adaptability and require significant design effort and material usage to achieve multiple suction configurations, making them less effective and more prone to faults for professional use.

Innovation Solution

A modular vacuum cleaner nozzle arrangement with interchangeable extension nozzles that provide multiple suction configurations through a single connection point, reducing material usage and increasing stability, featuring a vacuum cleaner nozzle, a first extension nozzle, and a second expansion nozzle with distinct geometries for varying cleaning scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple expansion stages are connected in parallel and/or series to expand application range, then the cleaning configurations are expanded, but the design complexity and susceptibility to malfunctions increase significantly

Engineering Contradiction:
Improvecleaning configurationsVSAvoiddesign complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base body is designed with a universal receptacle that can accommodate multiple different expansion nozzles (first expansion nozzle, second expansion nozzle, third expansion nozzle). Each expansion nozzle can be connected to the same base body, allowing a single base design to serve multiple cleaning functions. This multi-functionality approach expands cleaning configurations without proportionally increasing base body complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The vacuum cleaner nozzle system is divided into modular components: a base body and separate interchangeable expansion nozzles. This segmentation allows each component to be optimized independently while maintaining overall system versatility. The base body remains relatively simple while the specialized functionality is distributed across multiple interchangeable nozzle attachments.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple different expansion nozzles with various connection points are designed, then the cleaning scenarios are expanded, but the susceptibility to malfunctions increases

Engineering Contradiction:
Improvecleaning scenariosVSAvoidsusceptibility to malfunctions
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The base body features a universal receptacle design that works with all expansion nozzles. This standardized interface reduces the number of different connection types needed, thereby reducing potential failure points. The same receptacle accommodates first, second, and third expansion nozzles, each optimized for different cleaning scenarios but all connecting through the same reliable interface.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If modular vacuum cleaner nozzle systems with multiple connection points are proposed, then the application range is expanded, but the design complexity increases

Engineering Contradiction:
Improveapplication rangeVSAvoiddesign complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system separates complexity into interchangeable nozzle attachments rather than complicating the base body. The base body remains relatively simple with a single universal receptacle, while the specialized functionality for different applications is distributed across multiple separate nozzle designs that can be swapped as needed.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a vacuum cleaner nozzle arrangement comprising a vacuum cleaner nozzle (1) extending in a working direction (y) and in a transverse direction (x) perpendicular thereto to form a first suction configuration, with a nozzle body (2), a suction opening (16) arranged on its underside and connected to a suction channel (17), which defines a first working width (a1) in the transverse direction (x), and a suction connection port (3) for connecting the suction channel (17) to a suction air duct. The vacuum cleaner nozzle arrangement further comprises a first extension nozzle (4) for forming a second suction configuration, with a first extension body (5), a suction opening (7) arranged on its underside and connected to a suction channel (6), which defines a second working width (a2) in the transverse direction (x) that is larger than the first working width (a1), and a receptacle for connection to the vacuum cleaner nozzle (1).The suction channel (6) of the first extension body (4) can be connected to the suction opening (16) of the vacuum cleaner nozzle (1). According to the invention, a second extension nozzle (12) is provided to form a third suction configuration. This second extension body (13) has dimensions different from those of the first extension body (5), a suction opening (15) arranged on its underside and connected to a suction channel (14), and a receptacle (8') for connection to the vacuum cleaner nozzle (1). The suction channel (14) of the second extension body (13) can be connected to the suction opening (16) of the vacuum cleaner nozzle (1).
