Solution Overview

Problem

Conventional surface cleaning apparatuses face challenges in optimizing dirt collection capacity without increasing the size of the unit or reducing the dirt collection capacity when downsizing.

Innovation Solution

The dirt collection chamber is strategically positioned to occupy empty volumes within the housing, surrounding parts of the cyclone chamber and suction motor, allowing for increased capacity without size increments and reduced re-entrainment of dirt, while maintaining a compact design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the dirt collection chamber is enlarged to increase dirt collection capacity, then the dirt collection capacity is improved, but the size of the unit increases

Engineering Contradiction:
Improvedirt collection capacityVSAvoidsize of the unit
Core Design Contradiction:
Quantity of substanceVSVolume of stationary object

Solution Approach 1:

The dirt collection chamber is positioned to occupy empty volumes within the housing that would otherwise be unused space. The chamber is configured to surround portions of the cyclone chamber and suction motor, nesting the dirt collection function within the existing structural envelope of the vacuum cleaner components.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The dirt collection chamber utilizes three-dimensional empty space within the housing by extending in multiple directions - surrounding the cyclone chamber laterally and the suction motor in the longitudinal direction, effectively using volumetric space rather than simply expanding in one dimension.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Volume of stationary object

If the unit is downsized to improve portability, then the size and weight are reduced, but the dirt collection capacity is reduced

Engineering Contradiction:
Improvesize of the unitVSAvoiddirt collection capacity
Core Design Contradiction:
Volume of stationary objectVSQuantity of substance

Solution Approach 1:

The dirt collection chamber is strategically positioned to occupy empty volumes within the housing that surround the cyclone chamber and suction motor. This nesting approach allows the dirt collection chamber to utilize otherwise wasted space, maximizing dirt collection capacity within a compact unit footprint.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The dirt collection chamber is configured to occupy specific localized empty volumes within the housing rather than uniformly expanding the entire unit. By targeting specific void spaces around existing components, the design achieves optimal dirt collection capacity without increasing overall unit dimensions.

Inventive Principle:
Principle #3Local quality

3Quantity of substance

If the dirt collection chamber is positioned to occupy empty housing volume, then the dirt collection capacity is increased without size increase, but the housing design becomes more complex

Engineering Contradiction:
Improvedirt collection capacityVSAvoidhousing design complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The dirt collection chamber is integrated with the existing housing structure by occupying empty volumes within it. The chamber walls form part of the housing assembly, merging the dirt collection function with the structural envelope rather than adding a separate external component.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The housing structure serves multiple functions: it provides structural support, defines the unit exterior, and contains the dirt collection chamber within its empty volumes. The same housing space that would otherwise be unused void space is repurposed to provide dirt collection capacity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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 minimizes weight, making the apparatus more portable and effective for small spaces.

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 chamber results in some of the particulate matter in the airflow stream being disentrained from the airflow stream.

Methodology Applied
Scientific EffectCyclone separation: Cyclone Separation

Implementation Method 2

The rotation of the air in the cyclone chamber results in some of the particulate matter in the airflow stream being disentrained from the airflow stream.

Methodology Applied
Scientific EffectCentrifugal force: Centrifugal Force

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 chamber is positioned in the air flow passage. An associated dirt collection chamber is exterior to the cyclone chamber. The cyclone chamber 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 chamber or the dirt collection chamber.
