Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-operable surface cleaning apparatuses face challenges in maximizing dirt collection capacity without increasing the size of the unit or compromising airflow, often resulting in reduced usability in small spaces and increased weight.
Innovation Solution
The design positions the dirt collection chamber to occupy empty volumes within the housing, surrounding parts of the cyclone and suction motor, and incorporates a pre-motor filter with an enhanced surface area to reduce dirt re-entrainment and extend filter life, while maintaining compactness and reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the dirt collection chamber volume is increased to maximize dirt collection capacity, then the dirt collection capacity is improved, but the size of the unit increases
Solution Approach 1:
The dirt collection chamber is nested within the housing structure by utilizing the annular space between the cyclone assembly and the housing walls. The chamber is positioned to surround portions of the cyclone, effectively using the existing structural space rather than adding external volume. This nesting approach allows the dirt collection chamber to occupy empty volumes within the housing without increasing the overall unit size.
Solution Approach 2:
The dirt collection chamber is configured in an annular shape that surrounds the cyclone assembly, transitioning from a traditional linear or separate chamber layout to a dimensional arrangement that wraps around existing components. This annular configuration utilizes the radial space between the cyclone and housing, effectively three-dimensional packaging that maximizes dirt collection volume within the constrained unit footprint.

3Quantity of substance
If the dirt collection chamber is positioned to occupy empty housing volume, then the dirt collection capacity is improved, but the airflow passage configuration becomes more complex
Solution Approach 1:
The dirt collection chamber is merged with the housing structure, where the chamber forms an integrated part of the overall housing assembly. The annular chamber surrounds portions of the cyclone and is structurally combined with the housing walls, eliminating the need for separate, complex airflow passages that would be required if the chamber were a distinct external component. This merging simplifies the airflow configuration while maximizing dirt collection capacity.
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
This configuration enhances dirt collection capacity, reduces the unit's size and weight, and extends the filter's lifespan, enabling effective cleaning in small spaces with minimal airflow reduction.
Implementation Method 1
The air is drawn into the vacuum cleaner through a dirty air inlet and conveyed to a cyclone inlet. The rotation of the air in the cyclone results in some of the particulate matter in the airflow stream being disentrained from the airflow stream.
Implementation Method 2
The rotation of the air in the cyclone results in some of the particulate matter in the airflow stream being disentrained from the airflow stream.
Implementation Method 3
incorporates a pre-motor filter with an enhanced surface area to reduce dirt re-entrainment and extend filter life

AI summary
A surface cleaning apparatus comprises an air flow passage extending from a dirty air inlet to a clean air outlet. A suction motor is positioned in the air flow path. At least one cyclone is positioned in the air flow passage. An associated dirt collection chamber is exterior to the cyclone. The cyclone and the suction motor are positioned side by side and have generally parallel longitudinal axes. The dirt collection chamber may surround part of the suction motor. Alternately, or in addition, a pre-motor filter having an enhanced surface area may be provided by configuring the pre-motor filter to extend outwardly of the pre-motor filter, such as by overlie part of the cyclone or the dirt collection chamber.
