Wringer device for a mop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior wringer devices for cleaning tools lack the ability to adjust wringing strength, forcing users to apply either a full or no wringing action, leading to inefficient cleaning and potential muscular issues, and fail to separate cleaning solutions effectively.
Innovation Solution
A wringer device with a selector group that allows users to choose from multiple wringing configurations, adjusting the wringing strength and incorporating a design that separates cleaning solutions to prevent mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wringer device provides only a rest configuration and a wringing configuration, then the device structure remains simple, but the user cannot adjust the wringing strength to match different cleaning needs
Solution Approach 1:
The wringer device incorporates a command lever that can be positioned at multiple angular positions (0°, 45°, 90°, 135°, 180°), allowing the wringing strength to be dynamically adjusted between a rest configuration and a full wringing configuration. This enables the user to adapt the wringing action to different cleaning needs while maintaining a relatively simple mechanical structure through selective positioning rather than continuous adjustment.
Solution Approach 2:
The device changes the wringing parameter (wringing strength) by varying the angular position of the command lever, which directly controls the degree of compression applied to the cleaning tool. This parameter change approach allows for five distinct wringing configurations without requiring complex control systems, simply by modifying the mechanical position of the lever.
2Ease of operation
If the wringer device applies full wringing action, then the cleaning tool is thoroughly wrung, but the user experiences muscular strain and cannot apply precise controlled force
Solution Approach 1:
The command lever provides five discrete angular positions that enable progressive control over wringing force. Users can select intermediate positions (45°, 90°, 135°) between the rest and full wringing configurations, allowing precise control of wringing strength without requiring continuous manual force adjustment. This reduces muscular strain by distributing the effort across multiple controlled positions rather than requiring sustained full-force application.
3Manufacturing precision
If the wringer device allows continuous lever movement, then the user has flexible control, but the lever may stop at incorrect positions reducing wringing effectiveness
Solution Approach 1:
The command lever's continuous range of motion is segmented into five distinct angular positions (0°, 45°, 90°, 135°, 180°), each corresponding to a specific wringing configuration. This segmentation ensures the lever stops at predetermined, functionally optimal positions rather than arbitrary locations, improving position accuracy while maintaining a simple lever-based control mechanism without requiring complex positioning systems.
4Reliability
If the wringer device uses a single container for cleaning solution, then the device structure is simple, but the cleaning solution and dirty water mix reducing hygiene and efficiency
Solution Approach 1:
The liquid retention system is divided into two separate containers: a first container for holding clean cleaning solution and a second container for collecting dirty water. This segmentation prevents mixing between clean and contaminated solutions, maintaining hygiene and cleaning effectiveness. The separate container structure, while adding some complexity, ensures reliable solution separation that is essential for efficient floor cleaning operations.

Implementation Method 1
a wringer device...comprises a wringer group configured to move between a rest configuration, in which the cleaning portion of the tool is not subject to any wringing action, and a wringing configuration, in which the wringer group is arranged to exert a wringing action on the cleaning portion of the tool to cause the liquid that is present in the same to flow out
