Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaner housings with partially spherical shapes face challenges in integrating components due to the significant size of the waste separation and collection device, leading to oversizing or increased pressure losses.
Innovation Solution
A sled-type suction assembly with a waste separation and collection device positioned off-center, featuring a movable bowl lid and omnidirectional wheels, allowing components to be arranged efficiently within the housing without increasing its size, and ensuring optimal sealing and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the waste separation and collection device is integrated into a vacuum cleaner housing with a generally spherical shape, then the vacuum cleaner can achieve a compact and aesthetically pleasing design, but this leads to increased pressure losses due to convoluted fluid connections and non-optimized component arrangement
Solution Approach 1:
The patent positions the waste separation and collection device asymmetrically within the spherical housing, specifically placing it in a lower portion rather than centrally or symmetrically. This asymmetric arrangement allows for more direct and less convoluted fluid connections, reducing pressure losses while maintaining the spherical external shape for compactness and aesthetics.
2Quantity of substance
If the waste separation and collection device is made large enough to effectively collect waste, then waste collection capacity is improved, but the overall size of the vacuum cleaner housing must be increased to accommodate it
Solution Approach 1:
The waste separation and collection device is nested within the spherical housing in an optimized configuration. The bowl-shaped waste collection container is positioned in the lower portion of the housing, allowing it to be contained within the spherical envelope without requiring additional external volume. This nesting approach maximizes waste collection capacity while maintaining a compact spherical form factor.
3Stability of the object's composition
If the waste separation and collection device is positioned centrally in the housing, then structural balance is improved, but fluid and electrical connections to other components become non-optimized and more complex
Solution Approach 1:
The patent deliberately positions the waste separation and collection device asymmetrically in the lower portion of the housing rather than centrally. This asymmetric positioning, while potentially affecting structural balance, significantly simplifies fluid and electrical connections to the suction unit and other components, reducing overall system complexity and improving manufacturability.

AI summary
The suction assembly (1) comprises a suction unit housing (3) having a partially spherical outer surface (4); a suction unit; a waste separation and collection device (8) comprising a waste collection bowl (11) and a bowl cover (14); and first and second main wheels mounted to rotate relative to the suction unit housing (3). The waste collection bowl (11) has a partially spherical outer surface (110) accessible from outside the suction assembly (1). When the suction assembly (1) is in operation, the outer surface of the bowl (110) and the outer surface of the housing (4) partially form a generally spherical assembly.
