Compact Nonwoven Production Apparatus for Home Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The nonwoven industry lacks a small-scale production system suitable for non-industrial environments, such as home or institutional use, to produce customized nonwoven products like diapers and clothing, as existing methods require large machines and high output capacities.
Innovation Solution
A compact apparatus with a small footprint, incorporating moveable appliance heads for applying polymers and fibers sequentially, a curing system, and a user-friendly interface, allowing for layer-by-layer additive manufacturing of nonwoven products within a SOHO-scale enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large scale industrial machines are used for nonwoven production, then productivity and output capacity are improved, but device size and footprint area increase significantly
Solution Approach 1:
The apparatus segments the production process into sequential steps performed by different moveable appliance heads (spray nozzle for polymer, fiber applicator for fibers) that operate one after another on the same former, eliminating the need for multiple large parallel production lines while maintaining customized output capacity
Solution Approach 2:
The invention transitions from traditional horizontal spread-out industrial production lines to a vertical compact arrangement where multiple appliance heads are stacked or positioned vertically over a single former, dramatically reducing footprint area while preserving productivity through sequential operation in the vertical dimension
2Speed
If multiple material application units work simultaneously, then production speed is improved, but device complexity and space requirements increase
Solution Approach 1:
The appliance heads are designed to be moveable rather than fixed, allowing them to dynamically position themselves over different zones of the former and operate sequentially. This dynamic arrangement simplifies the overall system by using a single versatile applicator head that can service multiple positions, rather than requiring multiple fixed simultaneous applicators
Solution Approach 2:
The production process uses periodic sequential action where different appliance heads operate in alternating cycles (polymer spray phase, fiber application phase, curing phase) rather than continuous simultaneous operation. This periodic sequencing maintains production speed while reducing the number of components needed at any given moment
