Solution Overview
Problem
Existing methods for manufacturing three-dimensional net-like structures face challenges in reducing manufacturing costs and improving production efficiency while maintaining product quality and dimensional accuracy.
Innovation Solution
A three-dimensional net-like structure manufacturing apparatus with a nozzle having multiple rows of holes and a hole-free region, paired with inclined chutes and water supply ports, allows for simultaneous extrusion and tangling of filaments to form high-density surface layers and low-density inner layers, enabling efficient production of multiple structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the production rate is increased to reduce manufacturing cost and improve production efficiency, then productivity improves, but manufacturing precision deteriorates
Solution Approach 1:
The nozzle is divided into multiple independent hole groups (first hole group, second hole group, third hole group) arranged in different rows, allowing simultaneous extrusion of multiple filament assemblies. This segmentation enables parallel production of multiple three-dimensional net-like structures, significantly increasing productivity while maintaining precise control over each individual structure's dimensions through dedicated hole patterns and spacing.
2Productivity
If multiple three-dimensional net-like structures are produced simultaneously, then productivity improves, but device complexity increases
Solution Approach 1:
Multiple hole groups are integrated into a single nozzle body, allowing simultaneous extrusion of multiple filament assemblies through one apparatus. The nozzle combines first, second, and third hole groups with different hole patterns and spacings, enabling parallel production of multiple three-dimensional net-like structures with different specifications without requiring multiple separate extrusion devices, thus increasing productivity while avoiding proportional increases in device complexity.
3Manufacturing precision
If the nozzle has holes arranged in a specific pattern, then manufacturing precision improves, but device complexity increases
Solution Approach 1:
Different hole groups within the nozzle are designed with locally optimized hole patterns and spacings tailored to specific product requirements. The first hole group has a first hole pattern with first spacing, the second hole group has a second hole pattern with second spacing, and the third hole group has a third hole pattern with third spacing. This local quality approach allows precise control over the dimensional accuracy and structural characteristics of different regions of the extruded material, with each hole group optimized for its specific function while maintaining an integrated nozzle design.

AI summary
The object is to improve the production efficiency of three-dimensional net-like structures while maintaining the surface quality of the three-dimensional net-like structures. A second chute 6 is located below a hole-free region 33 and is provided between first chutes 4a and 4b. Filaments 20a and 20b located on longitudinal sides 22b and 22c at the periphery of assemblies 21a and 21b are in contact with the upper side of inclined surfaces 46a and 46b of the second chute 6 and inclined surfaces 46a and 46b of the second chute 6. Such contact disturbs the vertical fall of the filaments 20a and 20b and causes the filaments 20a and 20b to be tangled in loops with the adjacent filaments 20a and 20b and pass through the first chutes 4a and 4b and the second chute 46a and 46b, while being cooled down with water supplied from openings 51a, 51b and 51c.
