Surface cleaning device with sweeper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surface cleaning devices often face issues with inadequate suction for specific surfaces, debris tangling in roller brushes, and restricted movement due to wheels, making it difficult to clean effectively, especially in hard-to-reach areas.
Innovation Solution
A surface cleaning device with a handle assembly, battery assembly, and cleaning head assembly that includes a universal joint for pivoting, a rim to prevent tangle debris, and a combination of soft and hard bristles in the brush assembly to effectively sweep debris while allowing for adjustable suction and easy maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wheels are added to allow movement of the surface cleaning device, then mobility is improved, but the device requires more force to move and cannot rotate fully
Solution Approach 1:
The patent removes wheels from the surface cleaning device entirely, extracting the problematic component that restricted movement. The device achieves mobility through direct pushing and pivoting capability without any wheeled elements, thus eliminating the contradiction between mobility and movement freedom.
Solution Approach 2:
Instead of using wheels to enable movement (conventional approach), the invention inverts the approach by designing a device that moves through direct contact and pivoting on its base. This inversion allows full rotation and maneuverability that would be impossible with wheeled construction.
2Productivity
If roller brushes are used to collect debris, then cleaning effectiveness is improved, but long debris becomes tangled in the brushes preventing proper rotation
Solution Approach 1:
The patent extracts the roller brush component that caused tangling issues and replaces it with a suction-based collection system. Debris is collected through suction forces and deposited into a container without mechanical brushes, eliminating the tangling problem while maintaining cleaning effectiveness.
Solution Approach 2:
The invention replaces the mechanical roller brush system with a pneumatic suction system. Instead of using rotating brushes to gather debris mechanically, the device uses suction forces to draw debris into the collection container, substituting mechanical contact with fluid dynamic forces.
3Productivity
If suction is increased to improve debris collection, then cleaning capability is improved, but the device becomes less effective on specific surfaces with inadequate suction
Solution Approach 1:
The patent incorporates adjustable suction controls that allow the user to dynamically modify the suction power according to the specific surface being cleaned. This dynamic adjustment capability enables the device to adapt to different surfaces (carpet, hard floors, etc.) while maintaining effective debris collection, resolving the contradiction between suction strength and surface compatibility.

AI summary
A surface cleaning device for removing debris from a surface is described. The surface cleaning device comprises a cleaning head comprising a housing, wherein the housing defines an inlet and comprises brush chambers; at least one vent coupled to a top portion of the housing; and a sweeper assembly coupled to the housing and comprising brushes having bristles, wherein the cleaning head is configured create a suction with a surface by directing air flow into the housing through the inlet and out of the housing through the at least one vent.
