Hand Vacuum Cleaner Battery and Motor Nesting for Compact Form
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand vacuum cleaners lack a compact design that enhances maneuverability and ergonomics, limiting their ability to be used freely without cords and stored in smaller spaces.
Innovation Solution
A hand vacuum cleaner design with a motor and fan assembly nested between onboard energy storage members, incorporating a pre-motor and post-motor filter arrangement that reduces overall size and improves accessibility, featuring a handle with a hand grip and batteries positioned to allow for a compact form factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the motor and fan assembly and filters are positioned separately from the batteries, then the components can be easily accessed and maintained, but the overall size of the hand vacuum cleaner increases and maneuverability deteriorates
Solution Approach 1:
The motor and fan assembly and filters are nested between the batteries, utilizing the space between energy storage members to house other components. This nesting arrangement reduces the overall volume of the hand vacuum cleaner while maintaining accessibility of critical components for maintenance.
2Ease of operation
If the motor and fan assembly is nested between batteries, then the compactness and maneuverability improve, but the accessibility for maintenance deteriorates
Solution Approach 1:
The hand vacuum cleaner is divided into modular segments, with the motor and fan assembly and filters positioned as a separate module between the batteries. This segmentation allows the motor assembly to be independently accessed and maintained without disassembling the entire device, preserving ease of repair while achieving compactness.
3Use of energy by moving object
If more batteries are added to increase power, then the energy storage capacity increases, but the weight and overall size increase
Solution Approach 1:
The batteries are arranged in a distributed configuration around the motor assembly rather than in a single large block. This dimensional redistribution allows the energy storage capacity to be increased while maintaining a compact overall form factor and managing weight distribution for better balance and ergonomics.
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
The compact design enhances user maneuverability, improves ergonomics, and allows for easier storage, while maintaining effective air flow and filtration, reducing backpressure and air flow losses.
Implementation Method 1
an air treatment member configured to remove particles of dirt and other debris from an air stream
Implementation Method 2
an onboard energy source comprising a plurality of energy storage members, such as one or more batteries provided in one or more battery packs

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 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 around at least a portion of a filter and/or fan and motor assembly.
