Solution Overview
Problem
Existing surface cleaning apparatuses, such as hand vacuum cleaners, face challenges in efficiently emptying dirt and particulate matter without spreading dust or requiring users to handle dirty components, often necessitating the removal of parts that complicate the process.
Innovation Solution
A hand vacuum cleaner design featuring a housing that pivots between an in-use position and an emptying position, allowing both the air treatment chamber and filter chamber to be opened simultaneously, enabling dirt to be emptied and the filter to be removed without disassembling any components, with the housing's movement allowing for separate access to each chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the housing is designed to open both air treatment chamber and filter chamber simultaneously, then the emptying and filter replacement process is simplified and hygiene is improved, but the housing structure becomes more complex
Solution Approach 1:
The patent combines the opening mechanisms of the air treatment chamber and filter chamber into a single housing structure. When the housing opens, both chambers are simultaneously accessible, allowing users to empty dirt and replace filters in one operation. This merging of functions simplifies the user process while the internal structural design manages the complexity through integrated hinge and opening mechanisms.
2Ease of operation
If the housing is made rotatable to provide access to both chambers, then operational convenience is improved, but the device occupies more space and may have reduced stability
Solution Approach 1:
The housing is designed with rotatable and movable capabilities, transitioning from a static closed structure to a dynamic open structure. The housing can rotate about a longitudinal axis and move between closed and open positions, providing flexible access to both chambers. This dynamic design improves operational convenience while maintaining structural integrity through controlled movement mechanisms.

AI summary
A surface cleaning apparatus has a housing defining at least part of a cyclone chamber and a pre-motor filter chamber. In one embodiment, the housing is pivotally mounted to the main body of a hand vacuum cleaner. The housing is moveable between an in use position and an emptying position, in which the cyclone chamber and the pre-motor filter are concurrently openable.
