Mop Wringer with Translational Receptacle for Compression Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mop wringer devices struggle with providing clear feedback on compression force for low-compressibility mop covers, making it difficult for users to achieve effective wringing.
Innovation Solution
A wringer device with a basket-like receptacle that moves translationally within a support, utilizing spring elements and a guide system to provide gradual resistance and feedback, allowing precise metering of wringing force and preventing tilting or rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the receptacle is fixed in the support, then the structure is simple and stable, but the user receives no clear feedback on compression force for low-compressibility mop covers
Solution Approach 1:
The receptacle is made movable relative to the support through a guide system that allows translational movement. This dynamic configuration enables the receptacle to move gradually during compression, providing the user with tactile feedback on the compression force applied to low-compressibility mop covers, while maintaining a relatively simple structural design.
2Force
If the receptacle is rigid and fixed, then the wringing force is concentrated, but the pressing distance is too short to provide clear feedback
Solution Approach 1:
The receptacle is designed to move translationally within the support during the wringing process. This allows the pressing distance to be extended gradually, providing the user with clear feedback on compression progress while maintaining effective wringing force through the guided movement mechanism.
3Length of moving object
If the receptacle allows free movement, then the insertion depth increases for bulky mops, but the receptacle may tilt or rotate
Solution Approach 1:
The guide system is segmented into multiple guide elements distributed around the receptacle perimeter. These segmented guides work together to constrain the receptacle to translational movement only, preventing tilting or rotation while allowing sufficient insertion depth for bulky mops.
Solution Approach 2:
The guide system acts as an intermediary between the receptacle and the support, mediating the movement of the receptacle. It allows translational movement for increased insertion depth while simultaneously preventing unwanted tilting or rotation through its geometric constraints.

AI summary
A wringer device for a mop includes a basket-like receptacle in which the mop can be wrung out by being pushed in and a support for fastening the wringer device in a mop bucket. The receptacle can be guided in the support such that the receptacle can be moved in translation in an insertion direction of the mop.
