Rotating Mop Cleaner with Blocking Rib to Prevent Hair Entanglement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners that perform mopping by rotating mops risk operational failures due to hair and debris being introduced between the body and rotating plates, which can cause malfunctions.
Innovation Solution
Incorporating a blocking rib structure around the rotating plates with a lower end below the edge portion, forming a concentric circle with the rotating shaft, to catch hair and prevent it from entering the gap between the body and rotating plates, while a suction passage and guide wall direct dust into the suction area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rotating plate with mop is used for cleaning, then cleaning effectiveness is improved, but hair and debris can be introduced between the body and rotating plate causing malfunctions
Solution Approach 1:
A blocking rib is introduced as an intermediary structure between the rotating plate and the body. This rib protrudes downward from the body and forms a barrier that intercepts hair and debris before they can enter the gap between the rotating plate and the body, thus protecting the system from malfunctions while maintaining cleaning effectiveness
Solution Approach 2:
The blocking rib is designed as a separate structural element that segments the space between the body and rotating plate. By creating a distinct blocking structure, the system separates the cleaning function (rotating plate) from the protection function (blocking rib), allowing both cleaning effectiveness and reliability to be optimized independently
2Volume of moving object
If the rotating plate is positioned close to the body, then device compactness is improved, but hair can still be introduced into the gap
Solution Approach 1:
The blocking rib extends in the vertical dimension downward from the body, creating a protective barrier without increasing the horizontal footprint of the device. This vertical extension allows the rotating plate to remain close to the body for compactness while the rib projects into the gap space to block hair and debris from entering
3Reliability
If a blocking structure is added around the rotating plate, then hair prevention is improved, but rotation smoothness may be affected
Solution Approach 1:
The blocking rib is designed with specific dimensional characteristics - it protrudes downward but its lower end is positioned higher than the lower end of the rotating plate's edge portion. This creates a localized blocking effect at the critical gap area while maintaining sufficient clearance elsewhere, allowing the rotating plate to rotate smoothly without excessive friction or interference
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
Prevents hair and debris from entering the rotating plate's upper side and gap, ensuring smooth operation and reducing friction, effectively preventing operational failures.
Implementation Method 1
it is possible to prevent hair and the like from being introduced into the upper side of the rotating plate... by friction between the mops and the floor surface
Implementation Method 2
According to this type of cleaner, it is possible to easily remove foreign objects stuck to the floor through friction between the mops and the floor surface while the pair of rotating plates and the mops are rotating
