Cleaning element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing string mops are stiff and inflexible, which limits their cleaning performance, and while strings with multiple strands can absorb more cleaning liquid, they become excessively heavy, making them difficult to maneuver.
Innovation Solution
The cleaning element features textile strings with a unique configuration, where a first and second strand run longitudinally, a third strand runs transversely, and a fourth strand is disposed between the first and second strands, all connected by a support thread, allowing for three-dimensional deformation when exposed to moisture or heat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If strings are configured from individual fiber strands to improve flexibility, then flexibility is improved, but absorption capacity deteriorates
Solution Approach 1:
The string is segmented into multiple individual fiber strands (at least three strands) that are fixed together at specific locations. This segmentation allows each strand to move independently, providing flexibility, while the collective arrangement of multiple strands maintains absorption capacity.
Solution Approach 2:
The strands are arranged in a three-dimensional configuration with fixed points creating spatial structure. This dimensional arrangement allows the string to flex in multiple directions while maintaining volume for liquid absorption, resolving the contradiction between flexibility and absorption capacity.
2Quantity of substance
If strings comprise a plurality of strands to increase absorption capacity, then absorption capacity is improved, but weight increases making them difficult to maneuver
Solution Approach 1:
The string is divided into multiple thin strands rather than using fewer thick strands. This segmentation achieves the required absorption capacity through the cumulative effect of multiple lightweight strands, keeping the overall weight manageable while improving liquid absorption.
Solution Approach 2:
The strands are fixed together at specific local positions (first and second fixed locations) rather than uniformly throughout. This localized fixation maintains absorption capacity in the unfixed portions while minimizing weight increase from the fixation points themselves.
3Area of stationary object
If strings are configured as wide strips to increase contact face, then contact area is improved, but flexibility deteriorates
Solution Approach 1:
Instead of using wide continuous strips, the cleaning element uses multiple narrow strands fixed together. This segmentation provides sufficient contact area through the collective surface of multiple strands while maintaining flexibility as each narrow strand can bend independently.
Solution Approach 2:
The string structure transitions from a two-dimensional wide strip to a three-dimensional arrangement of multiple strands. This dimensional change allows the string to achieve contact area through spatial arrangement while maintaining flexibility through the narrow cross-section of individual strands.

Function Achieved in This Case
This configuration enhances the cleaning performance by allowing the strings to absorb more liquid and deform into a three-dimensional shape, which increases their volume and absorption capacity without increasing weight, making them easier to handle.
