Hand Vacuum Cleaner Component Layout for Balanced Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand vacuum cleaners face challenges in achieving a balanced design that optimizes the placement of heavy components like the motor and fan assembly and energy storage members, leading to discomfort during use.
Innovation Solution
The hand vacuum cleaner is designed with the motor and fan assembly and energy storage members positioned at opposite ends, creating a balanced distribution that enhances user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the motor and fan assembly and energy storage members are positioned close together, then the device complexity is reduced, but the balance and comfort during use deteriorates
Solution Approach 1:
The patent divides the heavy components into two separate groups: the motor and fan assembly on one end, and the energy storage members on the other end. This segmentation allows each group to be positioned independently to achieve optimal balance, resolving the contradiction between simple arrangement and user comfort.
Solution Approach 2:
The patent employs asymmetric positioning of components along the longitudinal axis, with heavy components distributed unevenly at opposite ends rather than clustered centrally. This asymmetric distribution creates a balanced weight profile that improves ergonomics while maintaining a relatively simple overall structure.
2Ease of operation
If the motor and fan assembly is positioned at one end and energy storage members at the other end, then the balance and comfort are improved, but the device complexity increases
Solution Approach 1:
The patent segments the component layout into distinct zones: a motor assembly zone at one end and an energy storage zone at the other end, with lighter components filling intermediate spaces. This segmentation simplifies the design process and manufacturing assembly while achieving the desired balance.
Solution Approach 2:
The patent utilizes the longitudinal dimension of the device to distribute weight, positioning heavy components at extreme ends along the length axis. This dimensional approach to weight distribution achieves balance without increasing cross-sectional complexity or vertical height.

AI summary
A hand vacuum cleaner has a hand vacuum cleaner axis that extends centrally from a front end of the hand vacuum cleaner rearwardly to a rear end of the hand vacuum cleaner. The hand vacuum cleaner has a cyclone assembly including a cyclone chamber and a dirt collection chamber. A line that extends in a common horizontal direction with the hand vacuum cleaner axis extends through the cyclone chamber and the dirt collection chamber.
