Hand Vacuum Layout for Better Ergonomics and Dirt Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand vacuum cleaners often compromise on ergonomics and dirt collection capacity due to the placement of components, leading to reduced usability and efficiency in cleaning.
Innovation Solution
The hand vacuum cleaner design features a pre-motor filter housing positioned rearward of the air treatment member, with a pistol grip handle mounted to the pre-motor filter housing and energy storage members placed to optimize ergonomics and expand the dirt collection region, allowing for enhanced ergonomics and increased dirt collection capacity without increasing the device's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pre-motor filter housing is positioned rearward of the air treatment member with the suction motor rearward of the pre-motor filter housing, then ergonomics is improved, but the device complexity increases
Solution Approach 1:
The patent positions components along the longitudinal axis of the handle, creating a linear rearward arrangement from air treatment member to pre-motor filter housing to suction motor. This dimensional ordering optimizes the center of gravity and weight distribution for improved ergonomics while maintaining a compact form factor.
2Ease of operation
If energy storage members are positioned in the pistol grip handle or at the lower end, then ergonomics is improved, but the device complexity increases
Solution Approach 1:
The energy storage members are specifically positioned in strategic locations within the pistol grip handle structure - either in the main body, at the lower end, or radially outward of the suction motor. This localized placement optimizes weight distribution and balance for improved ergonomics while integrating seamlessly into the existing component layout.
3Quantity of substance
If the air treatment member volume is expanded, then dirt collection capacity is improved, but the device complexity increases
Solution Approach 1:
The air treatment member is positioned between the upper end of the pistol grip handle and the pre-motor filter housing, utilizing the longitudinal space efficiently. When the hand vacuum cleaner is horizontal, the vertical projection of the handle's upper end extends through the pre-motor filter housing, maximizing the air treatment member volume without increasing overall device footprint.

AI summary
A hand vacuum cleaner has an air treatment chamber, a body portion, which houses a suction motor, a handle and at least one of a pre-motor filter and a post-motor filter. The hand vacuum cleaner has a forward portion and a rearward portion, the forward portion comprises at least the air treatment chamber and the rearward portion comprises at least one of the suction motor, the handle, and the at least one of a pre-motor filter and a post-motor filter. The rearward portion is rotationally mounted to the forward portion. The at least one of the suction motor, the handle, the pre-motor filter and the post-motor filter, which are not provided in the rearward portion, are provided in the forward portion.
