Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable disinfecting wipes often require soaking and have substantial weight issues, leading to potential instability during use.
Innovation Solution
The development of pre-saturated disposable disinfecting microfiber cloths with a low weight substrate and microfiber yarns attached in parallel rows of stitches, which are saturated with a disinfecting formulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a substantial weight nonwoven substrate is used, then the wipe maintains structural integrity during use, but the wipe becomes heavy and difficult to handle
Solution Approach 1:
The patent uses a composite structure combining a lightweight nonwoven substrate with an integrated microfiber layer. The microfiber component is attached in parallel rows to the substrate, creating a composite material that provides both structural integrity and lightweight properties. This composite approach allows the wipe to maintain stability during use while significantly reducing overall weight compared to traditional substantial weight nonwoven substrates.
2Weight of moving object
If the substrate weight is reduced, then the wipe becomes lightweight and easier to handle, but the wipe may fall apart during use
Solution Approach 1:
The lightweight nonwoven substrate is reinforced by integrating a microfiber layer attached in parallel rows. This composite construction provides the necessary structural integrity to prevent the wipe from falling apart during use, while maintaining the lightweight advantage. The microfiber component acts as a reinforcing element that distributes mechanical stresses across the substrate.
Solution Approach 2:
The microfiber layer is segmented into parallel rows rather than being a continuous layer. This segmentation allows the structure to flex and move without compromising integrity, while still providing sufficient reinforcement. The spaced arrangement of microfiber rows reduces material usage and weight while maintaining structural stability.
3Productivity
If the wipe is pre-saturated with disinfecting formulation, then cleaning performance is improved, but the wipe may lose structural stability
Solution Approach 1:
The composite structure of lightweight substrate with integrated microfiber provides enhanced liquid retention and distribution capabilities. The microfiber component has high surface area and capillary action properties that improve disinfecting formulation retention and release, enhancing cleaning performance while the composite structure maintains structural stability during the wet state.
