Solution Overview
Problem
Existing wiping cloths with multi-layer designs fail to ensure uniform application and consistent cleaning results due to dissimilar material properties and sensitivity to mechanical stress, leading to uneven cleaning agent distribution and potential premature release of cleaning agents.
Innovation Solution
A multi-layered wiping cloth with a drying-capable cleaning agent that is activatable by water, where the wiping and cleaning layer and storage layer are mechanically interconnected using fiber strand portions, ensuring uniform liquid transportation and consistent cleaning results across a surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multi-layered wiping cloths are used with dissimilar material layers, then storage capacity and cleaning function are improved, but uniform application of cleaning agent and consistent cleaning result deteriorate
Solution Approach 1:
The patent merges the storage layer and cleaning layer into a single integrated multi-layer structure where cleaning agent is incorporated into the storage layer itself. This combination ensures that the cleaning agent is uniformly distributed throughout the storage layer, which then releases it consistently to the cleaning layer during use, resolving the contradiction between storage capacity and uniform application.
Solution Approach 2:
The patent applies local quality by incorporating cleaning agent specifically into the storage layer rather than uniformly throughout all layers. This localized placement allows the storage layer to maintain its storage function while ensuring controlled, uniform release of the cleaning agent to the cleaning layer, preventing uneven distribution.
2Reliability
If microcapsules are used to encapsulate cleaning agent, then cleaning agent release is improved, but sensitivity to mechanical stress and premature bursting worsen
Solution Approach 1:
The patent extracts the cleaning agent from microcapsule encapsulation and instead incorporates it directly into the storage layer matrix. This eliminates the microcapsule structure entirely, removing the problem of premature bursting under mechanical stress while maintaining controlled release through the storage layer's inherent properties.
Solution Approach 2:
The patent uses composite material structure where the cleaning agent is integrated into the storage layer material matrix rather than being enclosed in separate microcapsules. This composite approach provides mechanical strength to protect the cleaning agent while enabling controlled release, resolving the contradiction between reliability and strength.
3Strength
If material layers are sewn on peripheries, then structural integrity is improved, but uniform cleaning result across surface deteriorates
Solution Approach 1:
The patent merges the cleaning agent storage and release function directly into the storage layer, eliminating the need for separate peripheral sewing structures. This integration ensures that the cleaning agent is uniformly distributed and released across the entire surface area, providing consistent cleaning results while maintaining structural integrity through the layered design.

AI summary
The present invention relates to a wiping cloth which is configured so as to be multi-layered and has at least two material layers lying directly on top of one another, of which one first outer material layer forms an external wiping and cleaning layer, and of which the second material layer is configured as a storage layer. In order for such a wiping cloth which by way of a fixedly established surface facilitates a consistent application of cleaning liquid to be achieved, it is provided according to the invention that the at least two material layers lying on top of one another are made from a textile material preferably of at least approximately identical absorbency or water-release capability, in that the wiping and cleaning layer and the storage layer are mechanically interconnected in a planer manner, and in that a cleaning agent that is reactivatable by adding water is provided in at least one of the material layers lying on top of one another.
