Hand Vacuum Cleaner Weight Distribution for Improved Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand vacuum cleaners often have weight distribution issues, making them difficult to maneuver and clean hard-to-reach areas effectively due to the placement of heavy components.
Innovation Solution
A hand vacuum cleaner design with an energy storage unit at the lower end and a pistol grip handle above it, along with a suction motor positioned above the energy storage unit, allows for balanced weight distribution and easy handling, featuring a cyclone chamber and dirt collection chamber configuration that reduces backpressure and height, enhancing maneuverability and cleanability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If heavy components (energy storage unit, suction motor) are positioned in conventional locations, then structural stability is maintained, but weight distribution becomes unbalanced making the device difficult to maneuver
Solution Approach 1:
The patent repositions components along the vertical dimension of the device. The energy storage unit is moved to the lower end while the suction motor is positioned above it, creating a vertical weight distribution that balances the center of gravity. This dimensional rearrangement allows the heavier energy storage unit to be lower while the lighter suction motor sits above, improving handling without sacrificing structural stability.
2Ease of operation
If cyclone chamber and dirt collection chamber are positioned conventionally, then component accessibility is maintained, but device height increases reducing cleanability of hard-to-reach areas
Solution Approach 1:
The patent implements a nested configuration where the dirt collection chamber is positioned within or adjacent to the cyclone chamber structure. This nesting arrangement allows the dirt collection chamber to be accessed and emptied without significantly increasing the overall device height, enabling the vacuum to reach hard-to-access areas while maintaining component accessibility for user operation.
3Productivity
If air flow path is not optimized, then component layout is simple, but backpressure increases reducing cleaning efficiency
Solution Approach 1:
The patent incorporates a pre-motor filter positioned in the air flow path before air enters the suction motor. This preliminary filtration action removes particles that could clog or damage the motor, maintaining optimal air flow and reducing backpressure. The filter is integrated into the housing structure, allowing efficient air flow path design without excessive complexity.
