Vacuum Cleaner Head Partition Design for Large Debris Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaner heads for vacuum cleaners often push large debris across surfaces rather than drawing it in due to the close proximity required for effective pick-up performance.
Innovation Solution
A cleaner head design featuring an agitator, housing with a chamber, and a partition that creates a settling region with debris openings and a debris deflector to guide large debris into the settling region, ensuring effective pick-up of both small and large debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the sole plate is positioned close to the surface being cleaned to maintain pick-up performance, then small debris and dust can be effectively drawn through the suction opening, but large debris is pushed across the surface rather than being drawn in
Solution Approach 1:
The cleaner head is segmented into distinct functional zones: an agitating region with the brush bar for loosening debris, a transition region with the partition and debris openings for guiding large debris, and a settling region for capturing both large and small debris. This segmentation allows each zone to perform its specific function optimally without interfering with others.
Solution Approach 2:
The partition acts as an intermediary element between the agitating region and the settling region. It includes a first debris opening for small particles and a second debris opening for large debris, mediating the transition of different debris types from the brush bar area to the settling region where they can be effectively captured by suction.
2Productivity
If a partition with debris openings is introduced to guide large debris into the settling region, then large debris can be effectively captured, but the device complexity increases
Solution Approach 1:
The partition serves multiple functions simultaneously: it separates the agitating region from the settling region, guides large debris through the second debris opening, allows small debris through the first debris opening, and structures the airflow pattern. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The partition extends vertically at an angle within the chamber, creating a three-dimensional structure that organizes debris flow in multiple directions. The first debris opening is positioned lower and the second debris opening higher up, utilizing vertical dimensionality to handle different debris types effectively.

Function Achieved in This Case
The design enhances the vacuum cleaner's ability to pick up both small and large debris and dust, maintaining effective sealing and pick-up performance on various surfaces, including hard floors with compacted dust.
Implementation Method 1
a partition is disposed between the agitator and the dirty air outlet such that the partition and the housing define a settling region of the chamber adjacent the dirty air outlet
Implementation Method 2
debris swept past the first debris opening by the agitator is swept towards the second debris opening
