Cyclone Module Layout for Low-Height Stable Vacuum Cleaners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners with cyclonic dirt separation systems face challenges in efficiently separating dust and debris while maintaining stability and reducing the overall height, particularly in canister designs where the cyclone separator and dirt collection chamber orientation affects the unit's balance and cleanliness.
Innovation Solution
A vacuum cleaner design featuring a cyclone module with a separation chamber having an inlet opening at the lower portion, a cyclone outlet at the lower portion, and an exhaust grill that directs dirty air in an upward helical path for separation, with a debris outlet guiding dust into an adjacent dust collection chamber, and a removable filter assembly for improved airflow and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cyclone separator and dirt collection chamber are positioned in a vertically stacked orientation, then the separation efficiency is improved, but the overall height of the cyclone module increases
Solution Approach 1:
The patent transitions from a vertical stacking arrangement to a horizontal parallel arrangement of the cyclone separator and dirt collection chamber. This dimensional change allows the components to be positioned side-by-side rather than one above the other, reducing the overall height of the module while maintaining the functional relationship between separation and collection chambers
2Length of moving object
If the cyclone separator and dirt collection chamber are positioned horizontally, then the overall height is reduced, but the center of gravity stability deteriorates
Solution Approach 1:
The patent positions the dirt collection chamber beneath the cyclone separator in a horizontal arrangement, using the weight of the collected debris as a counterbalancing element. This strategic placement of mass lower in the structure helps lower the center of gravity and improve stability, counteracting the potential instability from the horizontal orientation
3Ease of repair
If the exhaust grill is made removable, then the ease of maintenance is improved, but the device complexity increases
Solution Approach 1:
The exhaust grill is designed as a separate, removable component that can be detached from the cyclone separator assembly. This segmentation allows the grill to be easily removed for cleaning and maintenance without disassembling the entire cyclone module, while the modular design minimizes the increase in overall device complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances the separation efficiency of dust and debris, improves the stability of the vacuum cleaner by lowering the center of gravity, and allows for easy maintenance by making components like the exhaust grill and filter assembly removable.
Implementation Method 1
highspeed rotational motion of the air/dirt to separate the dirt by centrifugal force
Implementation Method 2
maintain a flow of dirty air from the inlet port through the cyclone separation chamber
