Handheld Vacuum Motor Layout for Lower Vibration and Easier Dust Cup Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld vacuum cleaners suffer from vibrations due to the proximity of the electric motor to the handle, discomfort from the air outlet's location near the human body, and inconvenient assembly/disassembly of the dust cup in existing designs.
Innovation Solution
The electric motor is positioned between the air inlet and dust cup, with various orientations (oblique, horizontal, vertical) and a communicating channel system, along with a detachable dust cup and cyclone drum filtration, to improve structure diversity and user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electric motor is disposed close to the handle for compact structure, then the structure is simplified, but the handle vibration increases and sense of touch deteriorates
Solution Approach 1:
The electric motor is extracted from its conventional position near the handle and relocated to the dust cup assembly area. This separation removes the vibration source from proximity to the user's hand, eliminating handle vibration while preserving compact overall structure through strategic component redistribution.
Solution Approach 2:
The motor positioning transitions from a linear arrangement along the handle axis to a distributed spatial configuration where the motor is integrated into the dust cup assembly. This dimensional repositioning allows the motor to be farther from the handle in three-dimensional space while maintaining compact device footprint.
2Device complexity
If the air outlet is disposed close to the handle for compact structure, then the structure is simplified, but user comfort decreases
Solution Approach 1:
The air outlet is extracted from its position near the handle and relocated to the dust cup assembly area, specifically positioned away from the user's body. This separation removes the discomfort factor while maintaining compact structure through integrated dust cup design.
3Ease of manufacture
If the dust cup is integrated into the main body for simple structure, then manufacturing is simplified, but assembly and disassembly convenience decreases
Solution Approach 1:
The dust cup is segmented from the main body as a separate, detachable component. This segmentation enables easy assembly and disassembly for dust disposal and filter maintenance, while the modular design allows for simplified manufacturing of individual components that can be produced independently and assembled through straightforward connection mechanisms.
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 configuration reduces handle vibration, enhances user comfort by distancing the air outlet from the body, and simplifies dust cup assembly/disassembly, improving the overall cleaning experience and efficiency.
Implementation Method 1
a cyclone drum which is disposed inside the body and provided with a cyclone drum inlet communicating with the inlet
Implementation Method 2
an electric motor disposed between the air inlet and the dust cup, in which a dusty airstream entering into the housing from the air inlet flow through the dust cup and the electric motor successively
