Butterfly Mop Wringer Assembly for Progressive Pressure Wringing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mop wringer devices fail to apply uniformly progressive pressure, leading to inefficient liquid removal and user fatigue, and often interfere with mop operation after use.
Innovation Solution
A wringer assembly with slideable wringer arms and cam surfaces that apply progressive pressure to carrier plates, preventing rotation and allowing for easy mop handling post-use, with biased hinges and detachable absorbent material attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional wringer devices are used, then liquid removal is achieved, but uniform progressive pressure cannot be applied and user fatigue occurs
Solution Approach 1:
The wringer assembly is made movable along the handle via a slideable mechanism, allowing it to dynamically engage and disengage from the carrier plates. This dynamic positioning enables the wringer to apply progressive pressure through cam surfaces while maintaining ease of operation through simple linear motion rather than complex mechanical engagement
Solution Approach 2:
Cam surfaces are introduced as an intermediary element between the wringer arms and carrier plates. These cam surfaces convert the linear motion of the wringer assembly into progressive rotational pressure on the carrier plates, achieving uniform liquid removal without requiring the user to directly apply complex forces
2Productivity
If wringer apparatus contacts carrier plates during operation, then wringing function is achieved, but mop freedom of movement is interfered with
Solution Approach 1:
The wringer assembly transitions from a fixed contact mechanism to a dynamic one that can engage only when needed. The slideable mechanism allows the wringer to move into contact with carrier plates during wringing operations and retract afterward, preserving mop freedom of movement during cleaning operations
Solution Approach 2:
The wringer assembly is segmented from the main handle structure through the slideable mounting mechanism. This segmentation allows independent movement of the wringer component, enabling it to contact carrier plates only during wringing while leaving the mop head free to move independently during cleaning operations
3Force
If carrier plates are biased beyond perpendicular position, then pressure application is increased, but adequate cleaning pressure cannot be maintained
Solution Approach 1:
The hinge mechanism incorporates a stop that limits the bias angle of carrier plates to substantially perpendicular position. This parameter constraint ensures that carrier plates maintain the optimal angle for applying adequate cleaning pressure to surfaces while preventing excessive biasing that would compromise cleaning effectiveness

Function Achieved in This Case
Ensures efficient liquid removal with reduced user effort and maintains mop mobility post-wringing, enhancing cleaning efficiency and user experience.
Implementation Method 1
Each arm is further equipped with a cam surface, such as a convex surface, proximal to the wringer engagement guide, intermediate from the end of the wringer arm and the attachment of the wringer arm to the wringer arm assembly body
Implementation Method 2
The center carrier piece has biased hinges along its sides by which two carrier plates are attached

AI summary
A floor mop composed of a handle portion, a wringer assembly portion and a mop portion. The handle is equipped with a wringer assembly that slideable moves along the length of the handle a predetermined distance. The wringer assembly has a guide that cooperatively engages the handle to limit travel of the wringer assembly. The wringer assembly has wringer arms that terminate in wringer engagement guide to engage wringer guides on the centerplates of the butterfly floor mop. Each arm further include a cam surface proximal to the wringer engagement guides that cooperative engage linearly inclined ramps to apply progressive pressure on an absorbent material to wring wash liquid during wash operations.
