Mop with Protruding-Pin Cleaning Elements for Uniform Contact Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning devices with chenille material loops have a limited surface area for contact and pressure distribution, making it difficult to effectively clean surfaces, as only the upper portion of the loop can be pressed against the surface with sufficient contact pressure, while the ends lie loosely on the surface.
Innovation Solution
The design features a cleaning device with rod-like elements adorned with protruding pins in a star shape, made from base strips with tufted connections, which increase the cleaning surface area and provide a rubbing effect for removing dirt, using chenille material with microfibers for enhanced absorption capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If loops or strands of chenille material are used as cleaning elements, then the cleaning device can be simple in structure, but the surface area for contact with the surface to be cleaned is limited and only the upper portion can be pressed with sufficient contact pressure
Solution Approach 1:
The cleaning element is segmented into multiple rod-like elements with pins protruding in different directions. Each rod-like element acts as an independent cleaning unit with multiple pins that can contact the surface simultaneously, effectively increasing the total cleaning surface area while maintaining structural simplicity
Solution Approach 2:
The cleaning elements transition from two-dimensional loops to three-dimensional rod-like structures with pins protruding in multiple directions (star shape). This dimensional change allows pins to contact the surface from various angles, significantly increasing the effective cleaning surface area and ensuring consistent contact regardless of head position
2Device complexity
If loops of chenille material are used, then the structure is simple, but the contact pressure distribution is uneven with only the upper portion receiving sufficient pressure
Solution Approach 1:
The cleaning element is divided into multiple rod-like elements with pins distributed in different directions. This segmentation ensures that contact pressure is distributed across multiple pins rather than concentrated on a single loop, creating more uniform pressure distribution across the cleaning surface
Solution Approach 2:
The pins protrude in asymmetric star patterns from each rod-like element, with pins oriented in multiple directions. This asymmetric arrangement ensures that regardless of the head's position or angle, multiple pins will always contact the surface with adequate pressure, eliminating the uneven pressure distribution problem of conventional loops
3Area of moving object
If pins protrude in multiple directions from rod-like elements, then the cleaning surface area and rubbing effect are improved, but the manufacturing complexity increases
Solution Approach 1:
The cleaning element is segmented into multiple identical rod-like elements with standardized pin arrangements. This segmentation allows for modular manufacturing where each rod-like element can be produced independently and then assembled, reducing overall manufacturing complexity despite the complex three-dimensional pin structure
Solution Approach 2:
The pins are arranged in standardized star patterns with specific geometric parameters. By defining standard parameters for pin arrangement (star shape, specific angles, uniform distribution), the manufacturing process can be standardized and automated, reducing complexity despite the multi-directional protruding structure
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
This design allows for efficient dirt and fluid pickup with minimal contact pressure, ensuring consistent surface contact and improved cleaning performance by increasing the surface area and stiffness of the cleaning elements.
Implementation Method 1
Chenille material made of microfibers is characterized by the fact that it can absorb not only non-polar substances such as fat, but also polar fluids through capillary action.
Implementation Method 2
The free ends of the pins create a kind of rubbing effect that can also remove stubborn dirt from a surface to be cleaned.
