Reticulated Odor Control Material for Absorbent Products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent products face challenges in effectively controlling odors due to difficulties in handling odor control agents in powder form, which lead to dusting issues and uneven distribution, and hydrophobic odor control particles can impair liquid absorption properties.
Innovation Solution
An absorbent product with a reticulated structure of odor control material, where odor control particles like activated carbon are bonded to a carrier material with transversal slits that expand into openings, allowing liquid permeability and maintaining odor adsorption without compromising absorption properties, and using a water-soluble binder for enhanced odor control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If odor control particles in powder form are used, then odor adsorption capability is improved, but handling difficulty and dusting problems increase
Solution Approach 1:
The odor control material is divided into multiple small particles that are distributed across the carrier material surface, allowing effective odor adsorption while preventing dusting through proper bonding to the carrier
Solution Approach 2:
A binder substance is introduced as an intermediary between the odor control particles and the carrier material, facilitating easy handling and application while maintaining the particles' odor adsorption properties
2Reliability
If odor control particles are applied to carrier material, then odor control is improved, but liquid absorption properties are impaired due to hydrophobic particles
Solution Approach 1:
The carrier material is designed with a porous structure that allows liquid to penetrate through to the odor control particles, ensuring that the hydrophobic particles do not block liquid absorption pathways
Solution Approach 2:
A composite structure is created combining the carrier material with odor control particles, where the carrier's porous nature complements the particles' odor adsorption capability while maintaining overall liquid permeability
3Loss of substance
If slitting method is used to create openings, then material waste is reduced and handling is improved, but manufacturing complexity increases
Solution Approach 1:
Slits are pre-formed in the carrier material before applying the odor control particles, allowing for efficient material utilization and simplified subsequent handling without requiring complex post-processing operations
