Floor Mop with Retractable Scrub Bar for Concentrated Cleaning Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat mops with large surface areas hinder the application of focused cleaning force on stubborn dirt, leading to inefficient cleaning methods such as increased solution use, repeated passes, or awkward scrubbing maneuvers.
Innovation Solution
A mop design featuring a base plate with a movable scrubbing mechanism that allows the scrub bar to extend through an opening, concentrating cleaning force on stubborn dirt, and a grip lever mechanism for easy activation, enabling targeted cleaning without sacrificing the main cleaning pad's surface area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large surface area cleaning pad is used, then cleaning efficiency for large areas is improved, but the ability to concentrate cleaning force on stubborn dirt deteriorates
Solution Approach 1:
The cleaning system is segmented into two distinct components: a large surface area cleaning pad for general cleaning and a concentrated scrubbing mechanism with a smaller contact area for stubborn dirt. This segmentation allows each component to optimize its function - the large pad covers area efficiently while the concentrated scrubber delivers focused force where needed.
Solution Approach 2:
The invention applies local quality by providing different cleaning characteristics in different regions of the cleaning head. The main cleaning pad has large surface area for general cleaning, while the scrubbing mechanism provides concentrated force application at a specific location. This allows the user to apply appropriate cleaning intensity to different areas of the floor based on dirt severity.
2Productivity
If a scrub brush is added to the mop, then cleaning capability for stubborn dirt is improved, but device complexity increases
Solution Approach 1:
The invention merges the cleaning pad and scrubbing mechanism into a single integrated cleaning head assembly. Both components work together in unison during the cleaning operation, eliminating the need for separate tools or multiple attachments. This integration maintains cleaning capability while reducing overall device complexity compared to systems requiring separate scrubbing tools.
Solution Approach 2:
The cleaning head is designed as a multi-functional unit that combines both wiping/cleaning functions and scrubbing functions in a single assembly. This universal design allows one device to perform multiple cleaning tasks that would otherwise require separate tools, thereby improving cleaning capability without proportionally increasing device complexity.
3Force
If the scrubbing mechanism is always in contact with the floor, then cleaning force concentration is improved, but the large cleaning surface area is compromised
Solution Approach 1:
The scrubbing mechanism is designed to be movable rather than fixed, allowing it to be dynamically positioned into contact with the floor only when concentrated cleaning force is needed. The user can activate the scrubbing function by applying downward pressure or operating a control mechanism, and can disengage it when not needed. This dynamic design allows the system to maintain large cleaning surface area while providing concentrated force on demand.
Solution Approach 2:
The scrubbing mechanism operates in periodic cycles rather than continuously. The user activates the scrubbing function periodically when encountering stubborn dirt, and returns to normal cleaning mode for general surfaces. This periodic activation allows the system to maintain its large cleaning surface area capability while providing concentrated force concentration when required by the cleaning task.

AI summary
A mop having a base plate, a handle, a joint connecting the plate to the handle, a first grip at the end of the handle, a scrubbing mechanism in the base, and a cleaning pad attached to the bottom of the base. The scrubbing mechanism includes a scrub bar, and is movable between an inactive position in which the bar is flush with or above the lower surface of the plate, and an active position in which the bar extends through an opening through the plate to be at least partially below the lower surface of the plate. The cleaning pad moves from being flat on the lower surface of the plate when the scrubbing mechanism is in the inactive position, and a second configuration in which at least a portion of the cleaning pad protrudes downwards from the lower surface when the scrubbing mechanism is in the active position.
