Vacuum cleaner nozzle combining a first suction head and a second suction head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vacuum cleaner nozzles with rectangular heads struggle to effectively access and clean hard-to-reach areas such as corners and baseboards, despite efforts to modify air flow and add suction devices, as they lack ergonomic design and efficiency for these specific surfaces.
Innovation Solution
A vacuum cleaner nozzle with a dual-head design, featuring a standard rectangular head and a specialized triangular head, where a pneumatic actuator and distributor element allow for adjustable suction configuration between the two heads, enabling optimal suction performance on various surfaces and in tight spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rectangular head nozzle is used, then suction performance on open surfaces is improved, but access to hard-to-reach surfaces such as corners and baseboards deteriorates
Solution Approach 1:
The nozzle is divided into two separate heads: a first head with a rectangular shape optimized for open surfaces, and a second head with a different shape (such as triangular or rounded) optimized for hard-to-reach surfaces. This segmentation allows each head to be specifically designed for its intended purpose, resolving the contradiction between performance on open surfaces and access to corners.
Solution Approach 2:
The nozzle assembly is designed to perform multiple functions by combining different head types that can be used interchangeably or simultaneously. The system can adapt to different cleaning scenarios (open surfaces, corners, baseboards) using a single multi-functional nozzle unit, eliminating the need for separate nozzles for different surfaces.
2Adaptability or versatility
If two separate nozzles are equipped (one rectangular, one for corners), then optimal performance in all circumstances is improved, but device complexity increases
Solution Approach 1:
Two previously separate nozzle functions (rectangular head for open surfaces and specialized head for corners) are merged into a single integrated nozzle assembly. This combining allows the user to have both capabilities in one device, reducing the number of separate nozzles needed while maintaining versatility across different cleaning scenarios.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dual-head design enhances suction efficiency by allowing the nozzle to adapt its suction performance for both open surfaces and difficult-to-reach areas, improving dust removal in corners and along baseboards while maintaining a compact and ergonomic structure.

AI summary
A vacuum cleaner nozzle (1) designed to be moved across a surface to be vacuumed, comprising a first head (2) which includes a first suction duct (6) connected by an airflow to a first suction inlet arranged on the underside of the first head (2). The vacuum cleaner nozzle (1) includes a second head (3) which extends forward from the first head (2) and which includes a second suction inlet arranged on the underside of the second head (3). The vacuum cleaner nozzle (1) includes a second suction duct (9) which extends at least partially into the second head (3) and which is connected by an airflow to the second suction inlet.The vacuum cleaner nozzle (1) includes at least one distribution element for modifying the suction distribution between the first and second suction ports. The distribution element may occupy at least one first distribution position in which it allows suction at least through the first suction port and a second distribution position in which it allows suction at least through the second suction port. The vacuum cleaner nozzle (1) also includes a pneumatic actuator (21) for moving the distribution element between the first and second distribution positions.
