Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held vacuum cleaners lack a compact and ergonomic design that allows for easy handling and efficient cleaning without the restriction of power cords, while maintaining effective dust separation and air flow management.
Innovation Solution
A hand-held, battery-operated vacuum cleaner with a motor/fan unit and dust separation device arranged in a compact, space-saving configuration where the motor/fan unit is positioned behind the dust separation device, and both have axes aligned essentially parallel to each other, with the axis of rotation of the dust separation device inclined forward, creating a slim and manageable form factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the motor/fan unit and dust separation device are arranged in a compact configuration with parallel axes, then the overall height and volume of the vacuum cleaner is reduced, but the air flow path and dust separation efficiency may be compromised
Solution Approach 1:
The patent transitions from a vertical stacking arrangement to a horizontal parallel arrangement of the motor/fan unit and dust separation device. This dimensional change allows both components to be positioned side-by-side with their axes aligned parallel to each other, reducing the overall height of the device while maintaining adequate space for air flow paths and dust separation processes to function effectively.
2Shape
If the axis of rotation of the dust separation device is inclined forward, then the visual appearance becomes more compact and ergonomic, but the internal space distribution and component alignment become more complex
Solution Approach 1:
The patent introduces an asymmetric inclination of the dust separation device axis forward at a predetermined angle relative to the vertical. This asymmetric orientation creates a more compact and ergonomic visual appearance, improving the handheld form factor. The design accepts the resulting complexity in internal space distribution and component alignment as a trade-off for achieving the desired aesthetic and ergonomic qualities.

Function Achieved in This Case
This design enables a lightweight, easy-to-handle vacuum cleaner that is suitable for one-handed operation, with a reduced overall height and a visually appealing appearance, while maintaining effective dust separation and air flow management, allowing for efficient cleaning without the need for power cords.
Implementation Method 1
The dust separating device is designed to rotate air entering via an air inlet area about an axis of rotation
Implementation Method 2
a suction opening and a motor/fan unit. The motor-fan unit is designed to generate a suction air flow that extends from the suction opening via a dust separation device to the motor-fan unit
