Sponge Roller Mop Quick-Release Mechanism for Hygienic Sponge Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sponge roller mops require users to touch and handle dirty sponges when replacing them, exposing them to dirt and germs, and involve complex mechanisms like J-hooks or tracks that complicate the process.
Innovation Solution
A quick release mechanism with a sponge pin molded into the brace, featuring a transverse pushbutton and vertical compression spring, allows the sponge to be released from the rollers without direct contact, using a lever handle to disengage the brace and pushbutton, enabling easy replacement of dirty sponges with clean ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sponge is retained using traditional J-hook or track mechanisms, then the sponge can be securely held during operation, but the user must touch the dirty sponge to remove it for replacement
Solution Approach 1:
A release mechanism acts as an intermediary between the user and the sponge. The release button triggers a mechanical system that disengages the sponge from the roller, allowing removal without direct user contact. This mediator transfers the interaction from direct manual handling to an automated release system.
Solution Approach 2:
The sponge retention system is designed to automatically release and eject the sponge when the release button is pressed. The mechanical linkage and spring system perform the removal action autonomously once triggered, eliminating the need for manual manipulation of the dirty sponge by the user.
2Object-affected harmful factors
If simple retention mechanisms are used, then the device structure is simpler, but the sponge cannot be released without manual handling
Solution Approach 1:
The retention system is divided into separate functional components: a retention mechanism that holds the sponge during operation, a release trigger system, and an ejection mechanism. This segmentation allows the complex release function to be isolated from the simple retention function, making the overall system manageable despite its complexity.
Solution Approach 2:
Multiple functions are combined into a single integrated release mechanism: the button press simultaneously disengages the retention clips, triggers the spring-loaded ejection, and releases the sponge from the roller. This merging reduces the number of separate controls and operations needed.
3Reliability
If the sponge is securely retained during mopping, then cleaning effectiveness is improved, but removal requires complex mechanisms like tracks or J-hooks
Solution Approach 1:
The retention system transitions between two dynamic states: a locked state during operation where the sponge is securely held, and an unlocked state during release where the retention clips disengage. This dynamic behavior allows strong retention when needed and easy release when triggered, without requiring permanently complex mechanisms.
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
Enables the safe and efficient removal of dirty sponges without touching them, simplifying the replacement process and maintaining cleanliness by eliminating the need for tracks or J-hooks, ensuring a hygienic and user-friendly experience.
Implementation Method 1
The pushbutton is moved in a transverse direction through a transverse spring which creates a transverse force
Implementation Method 2
the crown pushes against an internal vertical piston which then pushes against a vertical compression spring retained within a housing of the rod retaining mechanism. When this action occurs, the vertical compression spring is pushed into a compressed condition
Implementation Method 3
the lever handle is caused to move into a further downward position adjacent the handle of the sponge mop (as will be discussed) so that the metal brace or plastic brace is pushed away from and below the pair of rollers

AI summary
A mechanism by which the mop of a sponge roller mop is released without a user having to touch a dirty mop so that the sponge can be released and replaced with a clean sponge, including a sponge pin molded onto the brace which retains the sponge. The mechanism includes a transverse section with a movable hole through which the crown from the sponge pin is inserted. The wall is moved by a transverse spring force so that the wall from the opening of the trigger mechanism is placed between the crown and a lower section of the sponge pin to thereby retain the crown within the rod retaining mechanism. When a pushbutton is pushed transversely, it overcomes the spring force so that the crown is released and a downward force from the vertical compression spring forces the crown downwardly and out of the trigger mechanism, thereby releasing the sponge.
