Vacuum Cleaner Head Air Groove for Corner Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners face inefficiencies in suction power when cleaning corners due to the shape and volume of the cleaner head, which prevents smooth airflow and dust collection.
Innovation Solution
The design incorporates an air passage groove on the exterior side surface of the cleaner head that narrows towards the edge, allowing air to flow effectively along the groove and a brush that rotates to move dust into the nozzle connection portion, along with a shielding surface and side case that make contact with walls to form an enclosed passage for improved suction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cleaner head has a conventional shape and volume, then the structure is simple and easy to manufacture, but suction efficiency on corners is poor
Solution Approach 1:
The cleaner head is divided into multiple functional segments: a main body portion, a side case with air passage groove, and a shielding surface. The side case is further segmented into an air passage groove region and a brushing region. This segmentation allows each part to perform its specific function optimally while maintaining overall structural simplicity.
Solution Approach 2:
The side case is designed with differentiated local qualities: the air passage groove region has a groove structure to guide airflow along the wall surface, while the brushing region has brush members for cleaning. This local differentiation enables the cleaner head to handle both airflow management and dust collection in different areas simultaneously.
2Productivity
If the cleaner head makes contact with wall surfaces, then airflow is directed along the wall for better corner cleaning, but the structure becomes more complex
Solution Approach 1:
The air passage groove and the side case are merged into a single integrated component. The groove is formed directly on the exterior side surface of the side case, eliminating the need for separate airflow guidance components. This merging simplifies the overall structure while achieving the airflow direction control needed for effective corner cleaning.
Solution Approach 2:
The side case serves multiple functions: it provides structural support, guides airflow through the integrated air passage groove, and houses brush members for cleaning. This multi-functionality reduces the need for additional separate components, maintaining structural simplicity while improving corner cleaning efficiency.
3Productivity
If the air passage groove narrows toward the edge, then airflow is concentrated for better suction, but manufacturing precision requirements increase
Solution Approach 1:
The air passage groove width is designed to change gradually from the interior toward the edge of the side case. This gradual parameter change concentrates airflow toward the edge region where corner cleaning is needed, while the gradual transition makes the groove easier to manufacture with standard tolerances compared to abrupt width changes.

Function Achieved in This Case
This configuration enhances suction efficiency by directing airflow and dust collection specifically to the cleaning area, reducing outside air suction and improving dust removal from corners and edges.
Implementation Method 1
configured to allow air to flow along the air passage groove from the first edge region to the second edge region to a surface to-be-cleaned
Implementation Method 2
a brush rotatably disposed in an interior of the case and configured to rotate to move material from the surface to-be-cleaned into the case
