Solution Overview
Problem
Existing surface cleaning apparatuses, such as vacuum cleaners, face challenges in design where the cyclone bin assembly is difficult to detach and handle separately from the suction hose, leading to increased size and risk of impact damage to the hose connector, and inefficient dirt collection capacity.
Innovation Solution
A surface cleaning apparatus design featuring a removable cyclone bin assembly with a nested suction hose connector that remains connected to the main body, allowing independent handling of the cyclone bin assembly and enhanced dirt collection capacity by positioning the cyclone bin assembly on a platform with alignment members for secure mounting and easy emptying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cyclone bin assembly is integrated with the suction hose connector, then the apparatus structure is simplified, but the cyclone bin assembly becomes difficult to detach and handle separately
Solution Approach 1:
The apparatus is divided into separate functional modules: the cyclone bin assembly can be detached from the main body while the suction hose connector remains fixed on the main body. This segmentation allows independent handling of the cyclone bin assembly for emptying and cleaning without requiring detachment of the suction hose, resolving the contradiction between structural simplicity and operational ease.
2Ease of operation
If the suction hose connector is externally mounted, then the cyclone bin assembly can be easily removed, but the hose connector is exposed to impact damage and increases overall size
Solution Approach 1:
The suction hose connector is nested within the cyclone bin assembly structure, specifically positioned inside the dirt collection chamber opening. This nested configuration protects the hose connector from external impact damage while allowing the cyclone bin assembly to be easily detached from the main body for emptying, as the connector remains integrated with the removable assembly.
3Quantity of substance
If the cyclone bin assembly is made larger to increase dirt collection capacity, then more dirt can be collected, but the overall apparatus size increases
Solution Approach 1:
The cyclone bin assembly utilizes vertical space by extending downward from the main body, with the dirt collection chamber positioned in the lower portion. This vertical dimensionality allows increased dirt collection capacity without significantly increasing the horizontal footprint of the apparatus, maintaining a compact overall size while maximizing storage 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 design allows for easier manipulation and emptying of the cyclone bin assembly without the suction hose, reduces the overall size of the apparatus, protects the hose connector from impact, and increases the dirt collection capacity while maintaining a compact footprint.
Implementation Method 1
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

AI summary
A portable surface cleaning apparatus has a main body and air treatment member assembly is removably mounted to the main body. The air treatment member assembly air outlet and/or the suction motor inlet end is provided at the lower end of the air treatment member assembly when the surface cleaning apparatus is located on a floor and a pre-motor filter underlies the air treatment member assembly and/or the suction motor.
