Pivotable Particle Redirector for Precise Absorbent Core Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing absorbent cores with super absorbent polymers result in uneven distribution or require complex apparatuses for uniform distribution, limiting flexibility in design.
Innovation Solution
A pivotable particle redirector is used in conjunction with a mat-forming device to redirect super absorbent particles to specific areas of the absorbent core, allowing for flexible and precise distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If particles are sprinkled on top of fluff pulp layers or mixed throughout, then super absorbent polymers are distributed in the core, but the distribution is either concentrated in discrete zones or requires complex apparatuses for uniform distribution
Solution Approach 1:
The particle redirector is made pivotable about a pivot axis, allowing it to dynamically change its orientation during operation. This enables the redirector to be positioned at different angles to direct particles to different areas of the mould, providing precise control over particle distribution without requiring multiple fixed redirectors or complex positioning mechanisms
Solution Approach 2:
The particle redirector is divided into a plurality of separate redirectors, each capable of being independently pivoted about its own pivot axis. This segmentation allows different portions of the mould to receive particles in different patterns simultaneously, enabling complex distribution patterns while using simple individual redirector units
2Manufacturing precision
If a pivotable particle redirector is used to redirect particles to specific areas, then precise placement of particles is achieved, but the device complexity increases
Solution Approach 1:
Instead of moving the mould or the particle source to achieve different distribution patterns, the invention pivots the particle redirector in place. This inverted approach keeps the mould and particle source stationary while achieving the same effect by redirecting particles from different angles, simplifying the overall system architecture
Solution Approach 2:
The pivotable redirector can be automatically positioned and pivoted during the forming process, using the existing motion of the mould or particle delivery system to its advantage. The redirector leverages the natural flow of particles and the existing mechanical movements in the system to achieve precise placement without requiring additional complex positioning mechanisms
