Hand Vacuum Cleaner Battery Nesting for Compact Cordless Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand vacuum cleaners are limited by their size and design, which restricts maneuverability and ergonomics, particularly when used without a tethered power source.
Innovation Solution
A compact hand vacuum cleaner design with onboard energy storage members, where the fan and motor assembly and filters are nested between batteries, and a horizontally disposed cyclone with an external dirt collection chamber, reducing the overall size and enhancing maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hand vacuum cleaner uses an onboard energy source with multiple batteries, then the range and maneuverability are improved, but the size and weight increase
Solution Approach 1:
The motor and fan assembly is nested between the batteries, utilizing the space between energy storage members to house other critical components. This nesting arrangement allows the motor and fan to be positioned within the footprint of the battery array, rather than adding to it, thereby maintaining a compact overall size while accommodating all necessary components for cordless operation.
2Volume of moving object
If the motor and fan assembly is placed between batteries, then the compact design is improved, but the air flow path complexity increases
Solution Approach 1:
The air flow path is segmented into distinct regions: dirty air inlet, cyclone separation chamber, and clean air outlet. The cyclone chamber acts as an intermediate stage that separates dirty air from clean air, allowing the motor to be positioned between batteries while maintaining straightforward airflow paths. This segmentation simplifies the overall air flow design despite the compact component arrangement.

AI summary
A hand vacuum cleaner has an airflow path from an air inlet to a clean air outlet with an air treatment member and a fan and motor assembly in the air flow path. The hand vacuum cleaner has a cleaner body and a handle having a hand grip portion. The hand vacuum cleaner also includes a plurality of batteries. A portion of the motor and fan assembly and/or a portion of a filter component can be positioned beside and/or between at least some of the batteries. The batteries may be contained in a removable storage chamber. The storage chamber may be removably mounted to the hand vacuum cleaner beside and/or around at least a portion of a filter and/or fan and motor assembly. The batteries may be at a lower part of the hand vacuum cleaner, such as below a handle.
