Solution Overview

Problem

Existing three-dimensional knitted materials lack the ability to produce complex shapes with regular connections between layers, limiting their structural regularity and filtration properties.

Innovation Solution

The proposed three-dimensional knitted material achieves regular connections between layers by forming at least two loops in different planes from a thread of the preceding course or wale, allowing for the creation of complex shapes and enhanced filtration properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If traditional knitting methods with loops oriented in perpendicular planes are used, then connections between layers are formed, but the structural regularity is poor and complex shapes cannot be produced

Engineering Contradiction:
Improvecomplex shapeVSAvoidstructural regularity
Core Design Contradiction:
ShapeVSStability of the object's composition

Solution Approach 1:

The patent applies dimensionality change by forming loops in multiple non-perpendicular planes simultaneously. The knitting needle system uses at least two needles positioned at different angles to the knitting direction, creating loops that extend in multiple spatial dimensions rather than simple perpendicular planes. This enables the formation of three-dimensional complex shapes while maintaining structural regularity through the systematic arrangement of multi-planar loops.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If irregular connections between layers are used, then three-dimensional structure is formed, but the ability to produce complex shapes is limited

Engineering Contradiction:
Improveability to produce complex shapesVSAvoidregularity of connections
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies dynamics by making the knitting system adjustable and adaptable during the knitting process. The knitting needles can be positioned at variable angles and the loop formation can be dynamically controlled to create different connection patterns between layers. This dynamic capability allows the system to produce regular connections that can be systematically varied to form complex three-dimensional shapes with high manufacturing precision.

Inventive Principle:
Principle #15Dynamics

3Reliability

If simple loop formations are used, then knitting process is simple, but filtration properties are insufficient

Engineering Contradiction:
Improvefiltration propertiesVSAvoidloop formation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies the nesting principle by creating loops that are formed within and through existing loop structures. The multi-planar loops are nested within the three-dimensional knitted fabric structure, with loops running through multiple layers and planes. This nested loop configuration creates a complex three-dimensional network that enhances filtration properties by providing multiple pathways and surfaces for fluid passage, while the systematic nesting pattern maintains manufacturing feasibility.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The three-dimensional knitted material includes knitted layers that are connected to one another to form a three-dimensional product. Each wale or course in a layer is formed by using an end of a thread that is a continuation of a loop of the preceding course or wale or layer to create at least two loops of the current course or wale in different planes. The loops of the current course or wale are run through at least one loop of a neighboring wale or course or layer of the knitted material. The structural regularity of a knitted material is increased, making it possible to create three-dimensional products having a complex shape, inter alia, having internal cavities, and increasing the filtration properties of the material.
