Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning apparatuses with cyclone assemblies lack efficient designs for concurrent emptying of cyclonic stages, leading to inconvenient and time-consuming emptying processes.
Innovation Solution
A surface cleaning apparatus featuring a dual cyclone assembly with nested cyclonic stages and concurrently openable distal walls, allowing both cyclonic stages and dirt collection regions to be emptied simultaneously, enhancing operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cyclonic stages are used in series, then cleaning effectiveness is improved, but emptying complexity increases
Solution Approach 1:
The patent implements nested cyclonic stages where the second cyclone is positioned inside the first cyclone chamber. The second cyclone chamber is surrounded by the first cyclone's sidewall, creating a nested configuration that allows both cyclonic stages to be emptied through a single access point at the distal end, thereby maintaining high cleaning effectiveness while simplifying the emptying process
2Device complexity
If separate emptying procedures are used for each cyclonic stage, then structural simplicity is maintained, but time consumption increases
Solution Approach 1:
The patent merges the emptying function of multiple cyclonic stages into a single unified access point. The distal wall assembly provides common access to both the first and second cyclone chambers, allowing users to empty both stages simultaneously through one opening, thereby reducing time consumption while maintaining reasonable structural complexity
3Productivity
If distal walls are made concurrently openable, then operational efficiency is improved, but mechanical complexity increases
Solution Approach 1:
The distal wall assembly is segmented into movable and fixed portions that can be independently configured. The movable distal wall portion can be opened to provide access to both cyclone chambers, while the fixed distal wall portion maintains structural integrity. This segmentation allows concurrent emptying of both stages through a single coordinated opening action, improving efficiency without excessive mechanical complexity
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
Facilitates concurrent emptying of both cyclonic stages, improving user convenience and reducing the time required for cleaning and maintenance by allowing both stages to be emptied in a single operation.
Implementation Method 1
a first stage cyclone chamber and a first stage dirt collection region external to the first stage cyclone chamber... particulate matter separated in a cyclone chamber may travel to a dirt collection region exterior to the cyclone chamber by passing through the dirt outlet

AI summary
A surface cleaning apparatus comprises an air flow path extending from a dirty air inlet to a clean air outlet; a suction motor provided in the air flow path; and a cyclone bin assembly comprising first and second stage cyclones. The first stage cyclone is provided in the air flow path and comprises a first stage cyclone chamber having a first stage second end wall that is spaced from a first stage first end wall. The second stage cyclone is provided in the air flow path downstream of the first stage cyclone and comprises a second stage cyclone chamber having a second stage second end wall that is spaced from a second stage first end wall. The first stage second end wall and the second stage second end wall are concurrently openable and the second stage second end wall may be moveable separately from the first stage second end wall.
