Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat mop covers are not suitable for clean rooms due to particle formation and inadequate uniform liquid release, which affects disinfection efficacy in controlled environments.
Innovation Solution
A flat mop cover with a foam-material layer between elongate surfaces, capable of absorbing 4 to 20 times its dry weight in liquid without fibers, and a continuous foam-material layer for uniform liquid discharge, combined with a textile outer layer for abrasive properties and minimal particle release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional flat mop covers are used in clean rooms, then cleaning function is provided, but particle formation occurs and uniform liquid release is inadequate
Solution Approach 1:
The patent employs a foam material with controlled porosity that allows uniform liquid distribution while preventing particle formation. The porous structure enables capillary action for even liquid release across the cleaning surface, solving both the particle contamination issue and the uniform liquid release requirement simultaneously.
Solution Approach 2:
The invention uses a composite structure combining foam material layers with specific properties - a liquid-permeable outer layer for uniform discharge and an inner liquid-storing layer. This composite approach achieves both particle-free operation and reliable, uniform liquid release for effective disinfection in clean room environments.
2Object-affected harmful factors
If foam material is used to prevent particle formation, then particle contamination is reduced, but liquid absorption and uniform discharge capability must be optimized
Solution Approach 1:
The foam material is divided into functional zones with different porosity and absorption characteristics. The outer layer has controlled porosity for uniform liquid discharge, while the inner layer provides bulk liquid storage. This segmentation allows the material to simultaneously reduce particle contamination and maintain high liquid absorption capacity (4-20 times its dry weight).
Solution Approach 2:
Different regions of the foam material have locally optimized properties - the outer cleaning surface area has porosity optimized for uniform liquid release, while the inner bulk provides high absorption capacity. This local quality differentiation resolves the contradiction between particle-free operation and liquid storage capability.
3Duration of action of moving object
If liquid absorption capacity is increased for prolonged disinfection contact time, then disinfection efficacy is improved, but uniform liquid release becomes more difficult to control
Solution Approach 1:
The foam material's porous structure provides capillary channels that control liquid flow rate and distribution uniformly across the surface. This natural capillary action ensures that even with high liquid absorption capacity (4-20 times dry weight), the liquid is released uniformly over time, maintaining both prolonged contact time and uniform discharge without requiring complex manufacturing precision.
