Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand vacuum cleaners lack ergonomic design and efficient energy storage, leading to suboptimal hand feel and operational balance during use.
Innovation Solution
A hand vacuum cleaner with onboard energy storage, such as batteries, integrated into the handle, and a cyclone unit configuration where the suction motor is positioned above the cyclone chamber, allowing for improved ergonomics and balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If batteries are integrated into the handle of the hand vacuum cleaner, then energy storage efficiency is improved, but weight distribution and ergonomic design become problematic
Solution Approach 1:
The patent positions the batteries in the lower portion of the handle, utilizing vertical space arrangement to optimize weight distribution. This spatial configuration in the vertical dimension allows the heavy battery component to be placed lower, improving balance and ergonomics while maintaining efficient energy storage capacity
2Ease of operation
If the suction motor is positioned above the cyclone chamber, then operational balance is improved, but device complexity increases
Solution Approach 1:
The patent integrates the suction motor and cyclone chamber into a unified housing structure where the motor is positioned directly above the cyclone chamber. This merging of components into a compact vertical arrangement achieves operational balance while minimizing the overall device complexity through integrated design
3Productivity
If the inlet conduit axis is positioned above the cyclone chamber, then air flow efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs an asymmetric configuration where the inlet conduit axis is deliberately positioned above the cyclone chamber rather than in a symmetric or centered location. This asymmetric arrangement optimizes air flow efficiency by creating a specific flow path pattern, while the design incorporates tolerances and mounting features that accommodate the positioning requirements without excessive manufacturing precision demands
Applied Scientific Principles

Implementation Method 2
A moving path of air drawn into the cyclone inlet is maintained in the same direction until the air is discharged through the pre-motor filter unit via the cyclone
Implementation Method 3
a suction motor positioned above at least a portion of the cyclone chamber
Implementation Method 4
a pre-motor filter unit having a filter grill and a filter member

AI summary
A hand vacuum cleaner can include an air inlet conduit having an inlet conduit axis, a suction motor and fan assembly having a suction motor axis of rotation, and a cyclone unit comprising a cyclone chamber having a cyclone axis of rotation. The inlet conduit axis can be generally parallel to the cyclone axis and when the inlet conduit axis is horizontally disposed, the inlet conduit axis is positioned above the cyclone axis and a projection of the inlet conduit axis intersects the suction motor.
