Rotating Mop Press Mechanism for Jam-Free Wringing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor wipers are complex in design, with guide devices requiring precise matching for reliable folding, making replacement difficult and the wiping process cumbersome, especially when wiper plate wings are not rotatably mounted.
Innovation Solution
A wiper design where the pressing device forcibly rotates the wiping plate by a specific angle during displacement from the wiping to squeezing position, allowing automatic threading into the pressing device regardless of angular position, and featuring a rotatable pressing device with a guide groove for restricted guidance, enabling easy handling and effective squeezing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guide devices are provided for defined folding to ensure reliable squeezing in any position, then squeezing reliability is improved, but device complexity increases and guide devices must be carefully matched making replacement difficult
Solution Approach 1:
The pressing device is made rotatable about the handle axis, transforming a static guiding system into a dynamic one that can adapt to different angular positions of the wiper plate wings, eliminating the need for precise matching of guide devices
Solution Approach 2:
The rotatable pressing device can accommodate wiper plate wings at any angular position relative to the handle, making the system universal and eliminating the need for position-specific guide device configurations
2Ease of manufacture
If wiper plate wings are fixedly articulated and cannot rotate when folded out, then threading into pressing device is simplified, but handling flexibility in wiping position deteriorates
Solution Approach 1:
The pressing device rotates to actively engage wiper plate wings at various angular positions, allowing the wings to maintain rotation capability for flexible handling while the pressing mechanism adapts to capture them during the squeezing operation
3Ease of operation
If pressing device forcibly rotates wiping plate during displacement, then automatic threading into pressing device is achieved from any angular position, but device complexity increases
Solution Approach 1:
The pressing device incorporates rotational movement about the handle axis, allowing it to actively engage and rotate the wiper plate wings into the correct position for squeezing, achieving automatic threading from any starting angular position
Solution Approach 2:
The pressing device performs a preliminary rotational action to align and capture the wiper plate wings before the actual squeezing operation, ensuring proper positioning regardless of the initial angular configuration

AI summary
The invention relates to a mop, which may be designed in particular as a floor mop and has a handle and a pressing device, which can be moved along the handle, for pressing two pivotably mounted mop plate segments against each other. The known mops have the disadvantage that the folded-together mop plate segments must be inserted into the pressing device or that the mop plate cannot be rotatably designed. The invention avoids this by the pressing device being mounted rotatably in relation to the handle.
