Solution Overview

Problem

Existing textiles used in garments and gear often lack the necessary durability, cushioning, and tailored mechanical behavior for extreme environments, particularly in applications involving motion and movement.

Innovation Solution

A method and system for enhancing textile substrates through computer-controlled deposition of thermoplastic polymers using Fused Filament Fabrication (FFF) techniques, allowing for precise, three-dimensional application of polymers to improve mechanical, thermal, and aesthetic performance by varying attributes such as layout, thickness, density, and layering of polymer filaments on textiles.

VSEngineering Contradiction Analysis

1Reliability

If traditional textiles are used in garments and gear, then the items can be manufactured with standard textile properties, but the textiles lack the necessary durability, cushioning, and tailored mechanical behavior for extreme environments

Engineering Contradiction:

Solution Approach 1:

The patent applies local quality by depositing polymer material in specific patterns and locations on the textile substrate. The system can vary the layout, thickness, density, and layering of polymer filaments in different zones to provide tailored mechanical behavior where needed, such as enhanced durability in high-wear areas while maintaining flexibility in other regions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent creates composite materials by combining textile substrates with deposited polymer layers. This composite structure integrates the inherent properties of the textile with the mechanical strength and durability of the polymer, resulting in a material that exhibits both flexibility and enhanced durability for extreme environments.

Inventive Principle:
Principle #40Composite materials

2Strength

If polymer material is deposited on textile substrates to enhance performance, then abrasion resistance and tensile strength are improved, but the manufacturing process complexity increases

Engineering Contradiction:

Solution Approach 1:

The patent replaces traditional mechanical textile reinforcement methods with a deposition-based system that uses computer-controlled polymer application. This substitution allows for precise control of material placement and properties while simplifying the manufacturing process through automation and digital control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs parameter changes by controlling various deposition parameters such as polymer material viscosity, deposition temperature, nozzle movement speed, and layer thickness. By adjusting these parameters, the system can optimize both the tensile strength of the composite material and the efficiency of the manufacturing process.

Inventive Principle:

Solution Approach 1:

The patent applies preliminary action by preparing the polymer material in advance (melting and extruding through the nozzle) and using pre-programmed deposition paths based on digital models. This allows the system to maintain high precision while reducing manufacturing time through efficient material flow and optimized toolpaths.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent ensures continuity of useful action by maintaining continuous polymer material flow through the nozzle and implementing uninterrupted deposition processes. The system keeps the polymer material in a ready-to-deposit state and uses continuous nozzle movement along programmed paths, minimizing idle time while maintaining manufacturing precision.

Inventive Principle:
Principle #20Continuity of useful action
