Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foam cotton mops have inefficient wringing mechanisms that are labor-intensive, require large storage space, and limit adaptability during mopping due to their design, leading to increased material consumption and friction, which results in a cumbersome and costly cleaning experience.
Innovation Solution
A self-wringing foam cotton mop with a rotatable foam cotton head and a movable squeezing mechanism within a wringing frame that changes its position during upward and downward movements, allowing for greater deformation and reduced friction, enabling effective wringing and improved adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wringing bar has large transverse length to squeeze the entire collodion mop, then the wringing effect is improved, but the wringing frame becomes heavy and material consumption increases
Solution Approach 1:
The wringing bar is divided into multiple segments that can be independently positioned. Instead of using a single long wringing bar that spans the entire width of the collodion mop, the patent uses several shorter wringing bars arranged in sequence. This segmentation reduces the material consumption and weight of each individual wringing bar while maintaining the overall wringing capability through the cumulative effect of multiple segments working together.
2Reliability
If multiple rows of wringing bars are used to improve wringing coverage, then the wringing effect is improved, but the contact area increases and friction is greatly increased
Solution Approach 1:
The wringing bars are designed to be movable rather than fixed, allowing them to dynamically adjust their position and contact pressure. The wringing frame includes a squeezing mechanism that can move the wringing bars closer together or farther apart depending on the operational needs. This dynamic adjustment optimizes the contact area between the wringing bars and the collodion mop, reducing unnecessary friction while maintaining effective wringing when needed.
3Device complexity
If the collodion head is fixedly connected to the mop rod, then the wringing structure is simplified, but the adaptability for mopping corners and particular occasions is reduced
Solution Approach 1:
The connection between the collodion head and the mop rod is made detachable rather than fixed. The wringing frame includes a squeezing mechanism that can compress the collodion head against the mop rod to create a temporary fixed connection during wringing operations, but allows the collodion head to be easily detached when needed. This dynamic connection provides both the simplicity of a fixed structure during wringing and the versatility of a detachable structure for adapting to different mopping situations.
4Device complexity
If the collodion head is perpendicular to the axial direction of the mop rod during storage, then the storage structure is simple, but a very large space is required for storage and transportation
Solution Approach 1:
The collodion head is designed with a flexible connection to the mop rod that allows it to change its orientation dynamically. During storage and transportation, the squeezing mechanism can compress the collodion head to align it parallel to the axial direction of the mop rod, reducing the overall storage volume. During operation, the collodion head can be expanded and positioned perpendicular to the mop rod for effective mopping. This dynamic reconfiguration resolves the contradiction between storage simplicity and space efficiency.

AI summary
A self-wringing foam cotton mop with a labor-saving wringing operation is provided, comprising a mop rod and a foam cotton head, characterized in that: the foam cotton head is rotatably connected to a bottom end of the mop rod, and a wringing frame is disposed on the mop rod; during mopping, the foam cotton head is separated from the wringing frame; a squeezing mechanism capable of squeezing the foam cotton head by entering the wringing frame is disposed on the wringing frame; a position of the squeezing mechanism is changeable, so that the position of the squeezing mechanism when the foam cotton head is moved up relative to the wringing frame is different from the position of the squeezing mechanism when the foam cotton head is moved down relative to the wringing frame, and the first amount of deformation generated by the foam cotton head during an upward movement of the foam cotton head relative to the wringing frame is greater than the second amount of deformation generated by the foam cotton head during a downward movement of the foam cotton head relative to the wringing frame.
