Solution Overview
Problem
Existing hand-held vacuum cleaners face challenges in achieving effective dust collection and compact, visually appealing designs, particularly for use in difficult-to-reach areas and for cleaning without the need for a suction hose or nozzle.
Innovation Solution
A hand-held, battery-operated vacuum cleaner with a dust separating device featuring a slanted bottom surface that promotes dust separation through centrifugal force, allowing for efficient dust collection and a compact, manageable design by tilting the dust separating device and housing, which also facilitates easier battery access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the dust separating device is designed with a slanted bottom surface, then dust separation efficiency is improved, but the device complexity increases
Solution Approach 1:
The bottom surface of the dust separating device is designed with a slanted configuration instead of a flat surface. This geometric parameter change creates a running surface that utilizes centrifugal force to guide dust particles toward the collection chamber, improving dust separation efficiency without adding complex mechanical components
Solution Approach 2:
The slanted bottom surface creates a curved or inclined running surface that works in conjunction with the rotational centrifugal force. This curved geometry naturally guides dust particles along the incline into the collection chamber, enhancing separation efficiency through geometric design rather than complex mechanisms
2Ease of operation
If the vacuum cleaner is designed to be handheld and compact, then ease of operation is improved, but the volume of the dust collection device is reduced
Solution Approach 1:
The dust separating device is segmented into distinct functional zones: an upper separation chamber where centrifugal separation occurs, and a lower collection chamber with the slanted running surface. This segmentation allows compact arrangement of functions within a small overall volume while maintaining effective dust collection capability
Solution Approach 2:
The dust separating device is integrated within the handheld vacuum cleaner housing in a nested arrangement. The separation chamber and collection chamber are vertically stacked, with the slanted bottom surface of the separation chamber directly forming the running surface for dust collection, maximizing space utilization in the compact handheld form factor
3Productivity
If the slanted part of the bottom surface runs obliquely outwards towards the front, then dust collection is improved, but the shape of the device becomes asymmetric
Solution Approach 1:
The slanted bottom surface is designed with asymmetric orientation, running obliquely outwards towards the front of the device rather than symmetrically in all directions. This asymmetric configuration optimizes the running surface for the directional flow of dust particles generated by the centrifugal force, improving dust collection efficiency while accepting the asymmetric external shape

AI summary
A hand-held, battery-operated vacuum cleaner (1) has a suction opening (3/24) and a motor-fan unit (5), the motor-fan unit being designed to generate a suction air flow that differs from of the intake opening via a dust separator (4 / 22) to the motor-fan unit. The dust separating device is designed to rotate air flowing in via an air inlet area (11/25) about an axis of rotation (13/26). The dust separating device is designed as a dust separating device that is closed at the bottom, with at least part of the bottom surface (15) being designed as a slanted part (16/27) of the bottom surface, which runs at an angle relative to a transverse plane (18/29) of the axis of rotation.
