Dual Dirt Outlet Cyclonic Hand Vacuum for Angled Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface cleaning apparatuses, such as hand vacuum cleaners, face challenges when operated at angles, as dirt can accumulate and block outlets, reducing their dirt-carrying capacity and functionality.
Innovation Solution
Incorporating a dual dirt outlet design in the cyclone chamber, with outlets positioned front and rear, allows for continued operation at angles by providing alternate outlets for dirt disposal, and an improved air flow path with a pre-motor filter and suction motor placement for enhanced ergonomics and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single dirt outlet is used in the cyclone chamber, then the device structure is simple, but the dirt-carrying capacity is reduced when operated at angles
Solution Approach 1:
The single dirt outlet is segmented into multiple outlets (first and second dirt outlets) positioned at different locations in the cyclone chamber. This allows dirt to exit through different pathways depending on the device orientation, maintaining functionality when operated at various angles without significantly increasing overall structural complexity.
Solution Approach 2:
The dirt outlets are positioned at different spatial locations and orientations within the cyclone chamber. By adding the dimensional aspect of outlet positioning, the system can handle dirt discharge in multiple directions, enabling operational flexibility at various angles while the outlets remain integrated within the same chamber structure.
2Productivity
If the suction motor is positioned far from the cyclone chamber, then air flow path is simple, but ergonomics and efficiency are reduced
Solution Approach 1:
The suction motor is positioned in close proximity to the cyclone chamber, merging these two functional components spatially. This reduces the length of the air flow path between them, improving cleaning efficiency by minimizing air flow resistance while the air flow path itself remains relatively simple and direct.
