Mop Press Cam Track Layout for Spill-Free Bucket Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mop presses often allow liquid to spill outside the bucket during use, and their locking mechanisms can be difficult to unlock, reducing efficiency and causing the mop press to become unattached from the bucket.
Innovation Solution
A mop press design featuring a moveable press-plate with cam tracks and followers, a handle mechanism for easy operation by both left- and right-handed users, and a locking mechanism that allows secure attachment and easy removal from the bucket with a single upward movement, ensuring that pressed liquid is captured within the bucket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mop press is removably attached to the bucket for ease of use, then the bucket is easier to use, but the mop press may become unattached from the bucket during operation
Solution Approach 1:
The locking mechanism transitions between locked and unlocked states dynamically. During normal operation, the mechanism remains locked to maintain secure attachment. When removal is needed, the mechanism can be easily unlocked by applying upward force, allowing the mop press to be detached and reattached as needed.
Solution Approach 2:
The locking mechanism changes the attachment state parameter from locked to unlocked. The cam track and cam follower system transforms the upward removal force into a mechanical action that releases the locking arm, changing the attachment parameter from secured to detached state.
2Reliability
If a locking mechanism is added to secure the mop press to the bucket, then attachment reliability is improved, but the mechanism becomes difficult to unlock
Solution Approach 1:
The locking mechanism is designed to be dynamically controllable. The locking arm can easily transition between locked and unlocked states by applying upward force to the press-plate assembly, making unlocking simple while maintaining secure attachment during normal use.
Solution Approach 2:
Instead of requiring a complex unlocking action, the mechanism is designed so that the natural upward motion of removing the mop press from the bucket automatically triggers the unlocking action. The cam track geometry inverts the removal motion into the unlocking function.
3Productivity
If the press-plate moves against the wall to compress the mop head, then liquid is pressed from the mop head, but liquid may spill outside the bucket
Solution Approach 1:
The press-plate follows a controlled dynamic path defined by the cam track. The cam track guides the press-plate through a precise motion sequence that compresses the mop head while containing the liquid within the bucket, preventing spillage while maintaining effective wringing action.
Solution Approach 2:
The cam track acts as an intermediary mechanism between the handle operation and the press-plate motion. It mediates the force application to ensure the press-plate moves in a controlled manner that achieves effective compression while preventing liquid from escaping the bucket.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents liquid from squirting out of the bucket and provides an easy-to-use locking mechanism that maintains the mop press attached during use while allowing simple detachment, enhancing user efficiency and preventing accidental unattachment.
Implementation Method 1
Each sidewall includes a top cam track and a bottom cam track
Implementation Method 2
the excess liquid can be pressed from the mop head by compressing the head between the press-plate and the wall

AI summary
A mop press having a front wall and a pair of sidewalls is provided. The sidewalls each have a top cam track, a bottom cam track, and a bucket slot. The bucket slot defines a shoulder, where the bottom cam track is positioned below the shoulder. In some embodiments, the mop press includes a moveable press-plate and a handle mechanism. The handle mechanism includes a left and right couplings each configured to removably receive a pressing arm therein. In other embodiments, the mop press includes a locking mechanism having a locking arm rotatably supported by the sidewalls for movement between a locking position and an unlocking position. The locking position is above the unlocking position.
