Device for wringing out threads of a mop with flexible and absorbent threads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mop wringing devices are complex, expensive to manufacture, and have reduced bucket volume due to additional structural components, and they do not efficiently guide the wringing basket in rotation, affecting the wringing efficiency of flexible and absorbent mop fringes.
Innovation Solution
A wringing device with a perforated tank and an attached crown, where the wringing basket is guided in rotation using a mechanical bearing system that eliminates the need for a support extending below the basket, allowing for simpler and more economical manufacturing, and optimizing bucket volume by using a guide device that transmits torque through containment tabs and a rotation guide mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a raised part with bearing is added to the bucket to guide the wringing basket in rotation, then the rotational guidance is achieved, but the structure becomes more complex and manufacturing cost increases
Solution Approach 1:
The patent extracts the bearing from the bucket structure and places it on the wringing basket instead. This eliminates the need for a raised part in the bucket, simplifying the bucket structure while maintaining rotational guidance functionality. The bearing is now part of the basket assembly rather than the bucket assembly.
Solution Approach 2:
Instead of having the bucket support and guide the rotating basket through a raised structure, the invention inverts the approach by having the basket carry its own bearing and rotate around a simple support axis in the bucket. This reverses the traditional support-rotation relationship and simplifies the bucket structure.
2Reliability
If a raised part is added to the bucket to support the wringing basket, then the basket can be guided in rotation, but the bucket volume is reduced
Solution Approach 1:
The raised support structure is extracted from the bucket design. The bucket returns to a simple cylindrical shape with maximum volume, while the rotational support function is achieved through a different mechanism - a simple axis in the bucket配合bearing on the basket.
3Productivity
If a complex guide device and secondary bucket are used to guide the wringing basket and evacuate liquid, then the wringing function is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The device is segmented into simple functional components: the bucket for water, the wringing basket with perforations for drainage, and a simple rotational guide mechanism. Each component performs its function independently without complex integration, reducing overall device complexity while maintaining wringing efficiency.

Function Achieved in This Case
The solution provides a reliable, efficient, and cost-effective method for wringing mop fringes, increasing the bucket's water capacity and enhancing wringing efficiency by using a centrifugal effect, suitable for various mop sizes and types, while maintaining the basket's stability and facilitating easy maintenance.
