Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotating mop structures suffer from wear and tear issues, particularly at the n-shaped connector and covering disc, leading to a loosening of engagement and eventual failure to rotate the mop head effectively, impacting cleaning efficiency and durability.
Innovation Solution
A confining structure featuring a T-shaped body with a circular base, a linking element with n-typed and cylindrical sections, and stopping blocks with inclined surfaces, allowing the rotating rod to engage and disengage seamlessly for effective rotation and easy cleaning, while maintaining durability through precise engagement and disengagement mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the n-shaped connector closely engages the covering disc to drive rotation, then the rotating rod can effectively rotate the disc for dewatering, but wear and tear appears on the connector and disc after long-term use, causing engagement loosening and eventual failure
Solution Approach 1:
The covering disc is segmented into an upper disc body and a lower annular flange that protrudes downward. The flange is further divided into multiple engagement arcs distributed around its circumference. This segmentation distributes the rotational driving force across multiple contact points between the n-shaped connector and the flange, reducing wear at any single location while maintaining effective torque transmission for dewatering operation.
2Ease of operation
If the mop head is fixed in position, then the structure is stable, but the mop head cannot be easily rotated for cleaning different surfaces
Solution Approach 1:
The linking element incorporates a ball joint mechanism that connects the rotating assembly to the extending assembly. This ball joint provides dynamic adaptability, allowing the mop head to rotate freely for cleaning different surfaces while maintaining structural stability during operation. The spherical connection enables multi-directional movement without compromising the overall structural integrity.
3Speed
If the engagement between connector and disc is tight, then rotation is effective, but wear and tear increases over time
Solution Approach 1:
The covering disc is segmented into an upper disc body and a lower annular flange that protrudes downward. The flange is further divided into multiple engagement arcs distributed around its circumference. This segmentation distributes the rotational driving force across multiple contact points between the n-shaped connector and the flange, reducing wear at any single location while maintaining effective torque transmission for dewatering operation.
Solution Approach 2:
The engagement structure uses a ball joint mechanism that changes the contact parameters from a single-point tight engagement to a distributed multi-point contact. The ball joint allows for slight movement and adjustment, distributing the mechanical stress across a larger area and reducing wear intensity while maintaining sufficient rotational effectiveness for both cleaning and dewatering functions.

AI summary
A confining structure of a rotating mop has a one-piece loop on a disc thereof, at least two stopping blocks arranged on the loop, and an n-typed body of a linking element being arranged correspondingly to the surface of the loop and the bottom of each stand thereof having an engaging block corresponding to the position of the stopping blocks. When the rotating rod is perpendicular to the disc, the linking element is closely joined but movable with the engaging blocks. When the bottom of the engaging blocks cannot abut on the loop and slips, the stopping blocks fix the position by abutting on the engaging blocks for the rotating rod to rotate for dewatering by centrifugal force. When the rotating rod is leaning, the linking element is not closely joined with the engaging blocks.
