Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional premoistened cleaning wipes are inadequate for cleaning a wide variety of surfaces and detritus due to their single-layer texture and limited functionality, which fails to effectively address the diverse cleaning needs for different surfaces and types of materials.
Innovation Solution
A premoistened multilayered cleaning wipe comprising a liquid-permeable first layer with larger apertures and a second layer with smaller apertures, a core between them, and a free liquid cleaning composition containing surfactants, designed to provide different cleaning functionalities on both sides for effective surface cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-layer wipe structure is used, then the device complexity is reduced and manufacturing is simpler, but the adaptability to clean different surfaces and detritus types is insufficient
Solution Approach 1:
The wipe is divided into multiple layers, each with distinct functions: a first layer with larger apertures for absorbing liquid cleaning composition and a second layer with smaller apertures for trapping detritus. This segmentation allows each layer to specialize in specific cleaning tasks, enhancing overall adaptability without requiring a single complex structure.
Solution Approach 2:
The invention uses composite material structures with different aperture sizes and material properties in each layer. The combination of materials with varying pore structures creates a multifunctional wipe that can handle diverse cleaning needs, from liquid absorption to particle trapping, resolving the contradiction between versatility and structural simplicity.
2Reliability
If a multilayered structure with different aperture sizes is used, then the cleaning effectiveness on various surfaces is improved, but the manufacturing precision requirements increase
Solution Approach 1:
Different regions of the wipe (layers) have different aperture sizes tailored to specific functions. The first layer has larger apertures optimized for liquid penetration, while the second layer has smaller apertures optimized for detritus trapping. This local differentiation of quality allows each layer to excel at its specific task, improving overall cleaning reliability.
Solution Approach 2:
The invention employs porous materials with controlled aperture sizes in each layer. The porous structure allows for efficient liquid wicking and detritus filtration while maintaining manufacturing feasibility through established porous material fabrication techniques, balancing cleaning effectiveness with manufacturing precision requirements.
3Use of energy by moving object
If the first layer has larger apertures for liquid permeability, then the liquid cleaning composition delivery is improved, but the ability to trap small particles is reduced
Solution Approach 1:
The wipe is segmented into two functional layers: the first layer with larger apertures handles liquid cleaning composition delivery through efficient wicking, while the second layer with smaller apertures captures small particles and detritus. This segmentation resolves the contradiction by assigning different particle size ranges to different layers.
Solution Approach 2:
The first layer with larger apertures acts as an intermediary that efficiently transports liquid cleaning composition to the cleaning surface while allowing the second layer with smaller apertures to handle particle trapping. This intermediary structure optimizes both liquid delivery and particle capture without requiring a single layer to perform both functions simultaneously.
