Corrugated Cleaning Head Structure for Wider Dust Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices face challenges in effectively sticking and removing dust, hair, and dirt from a wide area of the cleaning sheet, particularly when the device is used in low spaces or with traditional joint structures that hinder rotational movement and stability, and there is a need for improved operability and stability when propping the handle.
Innovation Solution
A cleaning device with a wave-like corrugated surface on the base body and a pipe joint structure that allows smooth joining of cylindrical pipes, along with a handle that can rotate 360 degrees and be propped stably, featuring an end cap for enhanced stability and operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat cleaning surface is used, then the device structure is simple, but dust and dirt are easily stuck to the circumferential section and cleaning efficiency decreases
Solution Approach 1:
The cleaning surface is designed with a curved shape instead of a flat surface. The base body has a curved lower face that allows the cleaning sheet to conform to surfaces more effectively, preventing dust and dirt from accumulating at the circumferential edges and improving overall cleaning efficiency.
2Ease of operation
If a traditional joint structure is used, then the handle cannot rotate freely, but the device lacks adaptability for different cleaning angles and low spaces
Solution Approach 1:
The joint between the handle and cleaning head is designed to be rotatable, allowing the handle to rotate 360 degrees in the circumferential direction and move in the up-down direction. This dynamic joint structure provides adaptability for cleaning in low spaces and at various angles while maintaining ease of operation.
3Length of moving object
If the handle is long for standing operation, then the cleaning area is accessible, but the device becomes unstable when propped
Solution Approach 1:
The end cap is designed with a curved surface that allows the handle to be propped against walls or surfaces at various angles. The curvature enables the handle to find stable resting positions while maintaining its length for effective cleaning reach, thus improving stability when propped without sacrificing cleaning area accessibility.

AI summary
A lower face of a base body (15) includes a wave-like corrugated surface portion (19) of which cross-section in a direction perpendicular to a predetermined direction along which cleaning is performed with a cleaning device body (11) in a planar view is wave-shaped as having a ridge portion (17) and a valley portion (18) arranged alternately and continuously. The valley portion (18) of the wave-like corrugated surface portion (19) includes an oblique valley portion (18a) of which end part is opened to a side portion of the base body (15) facing to the predetermined direction as being extended obliquely against the predetermined direction to obliquely guide objects such as dust to be stuck to a cleaning sheet (13) in accordance with wiping of the surface to be cleaned.
