Cleaning Cloth Contact Layer with Grip Surface for Container Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning cloths and pads often fall out of their containers due to lack of secure holding mechanisms, making handling and removal cumbersome.
Innovation Solution
A cleaning cloth or pad with a reinforcing layer and a contact layer featuring a grip surface with increased frictional resistance, designed to prevent accidental falling and simplify removal by enhancing user interaction with the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cleaning cloth or pad is placed in a container without securing mechanisms, then the container structure remains simple, but the cleaning cloth falls out accidentally during handling
Solution Approach 1:
The contact layer is segmented into multiple functional zones: a smooth contact surface for cleaning and a grip surface with increased friction for handling. This segmentation allows the same layer to serve dual purposes - cleaning functionality and secure retention in the container through enhanced grip areas
Solution Approach 2:
The grip surface is applied locally to specific areas of the contact layer rather than the entire surface. This localized texturing provides enhanced friction and grip where needed for handling and container retention, while maintaining the smooth cleaning surface in other areas
2Ease of operation
If the cleaning cloth has a smooth surface only, then the cleaning function is optimized, but the handling and removal from container becomes cumbersome
Solution Approach 1:
The contact layer has different surface qualities in different locations: smooth areas for optimal cleaning performance and textured grip surfaces for improved handling. This local differentiation resolves the contradiction by providing both smooth cleaning surfaces and enhanced grip zones within the same layer
Solution Approach 2:
The contact layer serves multiple functions: it provides the cleaning surface, acts as a grip surface for handling, and enables secure retention in the container. This multi-functionality eliminates the need for separate components while improving both cleaning and handling operations
3Reliability
If a grip surface with increased friction is added to the contact layer, then handling and container retention are improved, but the manufacturing process becomes more complex
Solution Approach 1:
The surface properties of the contact layer are modified by changing the friction parameter locally. The grip surface is created by texturing or applying high-friction materials to specific areas, changing the surface characteristics from smooth to textured without fundamentally altering the manufacturing process
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 grip surface provides improved handling and secure retention within the container, preventing accidental ejection and facilitating easy extraction with increased frictional resistance, enhancing user comfort and cleaning efficiency.
Implementation Method 1
at least sectionally at least one texture in the form of a grip surface is formed only on the contact surface of the contact layer, wherein the grip surface has an increased frictional resistance compared to the contact surface
