Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing absorbent materials with a pulp layer and superabsorbent polymer (SAP) layer are limited in modifying the absorption performance due to a restricted distribution pattern of SAP, which restricts the range of performance modifications.
Innovation Solution
The use of multiple distribution devices to control the discharge amounts of different SAPs, allowing for varied distribution patterns and densities, enabling broader modification of absorbent material performance by changing the combination and distribution of SAPs while moving the pulp layer relative to the distribution openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single distribution device is used to distribute SAP, then the device structure is simple, but the distribution pattern is limited and performance modification range is small
Solution Approach 1:
The single distribution device is divided into multiple distribution devices (first distribution device and second distribution device), each capable of distributing different types of SAP. This segmentation allows for independent control of each distribution device, enabling varied distribution patterns and broader performance modification while maintaining manageable complexity through modular design
Solution Approach 2:
The multiple distribution devices are designed to distribute different types of SAP (first SAP and second SAP with different particle sizes) through a unified manufacturing system. Each distribution device can be independently controlled to achieve various distribution patterns, making the system universally applicable for producing absorbent materials with different performance requirements
2Adaptability or versatility
If one type of SAP is distributed through one distribution opening, then the distribution process is simple, but the absorption performance cannot be sufficiently modified
Solution Approach 1:
Different types of SAP with different particle sizes are distributed to different regions or mixed in controlled proportions to create local variations in absorption properties. The first distribution device distributes first SAP while the second distribution device distributes second SAP, allowing different areas of the absorbent material to have tailored absorption characteristics based on local SAP distribution
Solution Approach 2:
The system distributes multiple types of SAP (first SAP and second SAP with different particle sizes) simultaneously or sequentially to create a composite SAP layer. This composite structure combines the advantages of different SAP types, enabling broader absorption performance modification through the synergistic effect of multiple SAP varieties
3Adaptability or versatility
If the discharge amount of SAP is fixed, then the distribution process is simple, but the performance design flexibility is reduced
Solution Approach 1:
The discharge amounts of the first and second distribution devices are made independently adjustable and controllable, allowing dynamic modification of SAP distribution patterns. Each distribution device can vary its discharge amount based on performance requirements, enabling flexible performance design while the independent control mechanisms maintain manageable system complexity through modular adjustment capabilities

This approach expands the modifiable distribution pattern of SAP, increasing the degree of freedom in performance design and broadening the range of absorbent material performance modifications, allowing for tailored absorption performance across different areas of the material.
Implementation Method 1
a pulp pulverized and conveyed by a duct is suctioned in a predetermined pattern to form a pulp layer in which the pulp is fiber-laminated
Implementation Method 2
a first distribution opening through which a first distribution device discharges a first SAP and a second distribution opening through which a second distribution device discharges a second SAP are provided facing the pulp layer

AI summary
In a method and device for manufacturing an absorbent material, the degree of freedom in design can be increased by expanding a modifiable distribution pattern of an SAP and broadening the range in which the performance of the absorbent material can be modified. Pulverized pulp is suctioned in a predetermined pattern to form a pulp layer in which the pulp is fiber-laminated. A first distribution opening through which a first distribution device discharges a first SAP and a second distribution opening through which a second distribution opening discharges a second SAP are provided facing the pulp layer, and the first and second SAPs are distributed onto the pulp layer through the first and second distribution openings while moving the pulp layer relative to the first and second distribution openings. The first and second distribution devices can control the discharge amounts of the first SAP and the second SAP, respectively.
