Mop Holder with Asymmetric End Section for Secure Cover Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mop cover holders for clean rooms are not adequately flexible or easy to handle for cleaning hard-to-reach areas, and they often require additional securing mechanisms to prevent accidental slippage of the mop cover during use.
Innovation Solution
A holder with a core made of reversibly bendable, dimensionally stable strands or a flat strip of material, where at least one end is wider or thicker, allowing for optimal adaptability and secure fitting of the mop cover, combined with a covering that protects against contamination and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the holder is made flexible to reach hard-to-reach areas, then adaptability is improved, but the mop cover may accidentally slip off during wiping movements
Solution Approach 1:
The holder features an asymmetric cross-sectional design where at least one end has a wider or thicker section than the main body. This asymmetric geometry creates a mechanical interference fit that prevents the mop cover from slipping off while allowing the holder to maintain its flexible, bendable properties for reaching hard-to-reach areas.
2Strength
If the holder is made rigid to maintain structural stability, then strength is improved, but flexibility to reach hard-to-reach areas deteriorates
Solution Approach 1:
The holder is constructed with a segmented core structure consisting of multiple reversibly bendable strands or a flat material strip with fold lines. This segmentation allows the holder to bend and flex at controlled points while maintaining overall structural integrity and strength, enabling it to reach hard-to-reach areas without compromising structural stability.
3Reliability
If additional securing mechanisms are added to prevent mop cover slippage, then reliability is improved, but device complexity increases
Solution Approach 1:
Instead of adding complex securing mechanisms throughout the holder, the invention applies a localized geometric solution at the end section. The wider or thicker cross-sectional area at one end creates a simple mechanical barrier that prevents mop cover slippage without requiring additional components, fasteners, or complex securing 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
The holder provides secure, flexible, and adaptable cleaning capabilities, allowing for easy handling and repeated use in clean rooms, including autoclaving, without the need for additional securing devices, while maintaining dimensional stability and preventing contamination entry through microcracks.
Implementation Method 1
a core made of a plurality of reversibly bendable, dimensionally stable strands or a flat material strip
Implementation Method 2
The strands are preferably completely embedded in a sheath, thus protecting them from contact with the environment. This sheath also ensures that microcracks that may occur during multiple bends in a strand due to tensile and compressive, or even torsional forces, do not become a gateway for contaminants
