Pre-moistened cleaning pads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pre-moistened cleaning pads have lower mileage and capacity due to early loss of liquid composition and inadequate utilization of attachment portions for liquid replenishment, leading to reduced cleaning effectiveness.
Innovation Solution
Designing pre-moistened cleaning pads with attachment portions comprising pulp fibers and a liquid composition, where the attachment portion surface area consists of greater than 75% to less than 98% protrusions, and incorporating a higher percentage of pulp fibers, enabling fluid communication between the cleaning and attachment portions for extended cleaning performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the attachment portion is designed with high pulp fiber content (>40% by weight) and protrusion structure (>75% surface area), then the liquid composition capacity and mileage are improved, but the manufacturing complexity increases
Solution Approach 1:
The attachment portion utilizes a porous fibrous structure with high pulp fiber content (>40% by weight) that creates numerous void spaces for liquid composition storage. The protrusion structure with >75% of the surface area consisting of protrusions further enhances liquid retention capacity while maintaining the ability to transfer liquid to the cleaning portion during use.
Solution Approach 2:
The cleaning pad is divided into distinct functional portions: the attachment portion with high pulp fiber content and protrusion structure for liquid storage, and the cleaning portion for actual cleaning. This segmentation allows each portion to be optimized for its specific function while working together as an integrated system.
2Duration of action of moving object
If the cleaning pad uses conventional fibrous structure without sufficient wet compression properties, then the manufacturing is simpler, but the liquid composition is lost too early reducing mileage
Solution Approach 1:
The fibrous structure parameters are specifically optimized to achieve >40% pulp fiber content by weight and a protrusion structure where >75% of the attachment portion surface area consists of protrusions. These parameter changes enhance liquid retention and controlled release properties, extending the cleaning pad's effective mileage while maintaining manufacturability through established fibrous structure formation techniques.
3Reliability
If the attachment portion has low liquid composition capacity, then the overall pad structure is simpler, but the cleaning effectiveness is reduced due to insufficient liquid replenishment
Solution Approach 1:
The attachment portion is designed to automatically replenish the cleaning portion with liquid composition during use. The high pulp fiber content and protrusion structure enable the attachment portion to act as a self-replenishing reservoir, transferring liquid to the cleaning portion as needed without external intervention, thereby maintaining consistent cleaning effectiveness throughout the pad's mileage.
