Solution Overview
Problem
Vacuum cleaners often struggle to effectively pick up dirt along edges and in corners due to limitations in existing tools that fail to maintain suction and contact with surfaces in these areas.
Innovation Solution
A vacuum cleaner tool with a nozzle featuring a chamfered section and a further section, where the internal angle between them is greater than 90 degrees and less than 180 degrees, allowing for effective dirt pickup by maintaining contact with walls and preventing blockage, combined with suction openings on the base and sides for enhanced dirt collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the tool uses a conventional design with suction openings directly facing the cleaning surface, then it can effectively pick up dirt from open surfaces, but it fails to maintain good airflow and contact when cleaning along edges and corners
Solution Approach 1:
The front of the nozzle is segmented into a chamfered section and a further section, with the chamfered section being at least partly closed. This segmentation allows the tool to maintain different functions in different areas: the closed chamfered section maintains contact with walls for stability while the further section with suction openings maintains airflow for dirt pickup at edges and corners
Solution Approach 2:
Different sections of the nozzle front have different properties: the chamfered section is closed to maintain wall contact and structural integrity, while the further section has suction openings to maintain airflow. This local differentiation allows each section to perform its specific function optimally without compromising the other
2Ease of operation
If the tool is designed to contact walls along the front section for edge cleaning, then it can maintain stability and contact, but the suction opening may be covered and blocked by the wall
Solution Approach 1:
The front nozzle is divided into a closed chamfered section for wall contact and a separate further section with suction openings. This segmentation ensures that when the chamfered section contacts the wall for stability, the suction openings in the further section remain exposed and unblocked, maintaining both ease of operation and dirt pickup effectiveness
Solution Approach 2:
The suction openings are positioned in the further section which is spaced from the wall, creating a three-dimensional arrangement where the closed chamfered section contacts the wall surface while the suction openings in the further section remain in a different spatial plane, preventing wall blockage while maintaining contact
Applied Scientific Principles
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 tool ensures improved dirt pickup along edges and in corners by maintaining airflow and contact, while the additional suction openings on the sides help unblock and dislodge dirt, making it suitable for cleaning in tight spaces.
Implementation Method 1
dirt is drawn into the interior of the nozzle via the suction openings. From there, the dirt is carried to the vacuum cleaner via the duct

AI summary
A tool for a vacuum cleaner comprising a nozzle and a duct for attachment to a wand, hose or the like of the vacuum cleaner. One or more suction openings are provided in a base of the nozzle. A front of the nozzle comprises a chamfered section and a further section. A suction opening is then provided in the further section, and the chamfered section is closed. An internal angle formed between the chamfered section and the further section is greater than 90 degrees and less than 180 degrees.
