Solution Overview

Problem

Traditional textiles are suboptimal for functional apparel due to their intrinsic structure, which often does not align with the specific performance requirements of the final article, leading to increased material usage, waste, and weight.

Innovation Solution

Engineered textiles with oriented yarn strands secured by a bonding material, allowing for tailored directional elasticities and strengths to meet the functional demands of the final product without additional reinforcement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional woven or knit fabric structure is used to provide sheet integrity, then the fabric maintains structural stability, but the intrinsic structure does not align with functional performance requirements and increases material usage and weight

Engineering Contradiction:
Improvesheet integrityVSAvoidarticle weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The fabric structure is segmented into two distinct components: primary yarn strands that provide the main structural framework and secondary bonding material that provides localized reinforcement. This segmentation allows each component to be optimized independently - the primary strands can be arranged to match functional load paths while the bonding material is applied only where needed to maintain sheet integrity, reducing overall material usage and weight compared to traditional homogeneous woven structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bonding material is applied selectively at specific locations rather than uniformly across the entire fabric. This local quality approach ensures that reinforcement is provided only where structurally necessary to maintain sheet integrity, while other areas maintain the optimized primary strand arrangement for functional performance. This reduces unnecessary material usage and weight compared to traditional fabrics that require uniform structural properties throughout.

Inventive Principle:
Principle #3Local quality

2Reliability

If traditional woven or knit fabric structure is used to provide sheet integrity, then the fabric maintains structural stability, but secondary reinforcement structures are required which increase material usage and waste

Engineering Contradiction:
Improvesheet integrityVSAvoidmaterial waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The invention merges the structural framework function (primary yarn strands) with the reinforcement function (secondary bonding material) into a single integrated fabric structure. This combination eliminates the need for separate secondary reinforcement components that would require additional die-cut patterns and assembly steps, thereby reducing material waste from off-cuts and simplifying the manufacturing process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fabric is constructed as a composite material system combining primary yarn strands and secondary bonding material with different functional properties. The primary strands provide the main structural framework while the bonding material provides localized reinforcement, creating a composite structure that achieves both sheet integrity and functional performance without requiring additional separate reinforcement components that would generate waste.

Inventive Principle:
Principle #40Composite materials

3Ease of manufacture

If pre-produced rolled fabric with intrinsic structure is used, then manufacturing is simplified, but the structure is suboptimally arranged to meet functional demand requirements

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidfunctional performance alignment
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The primary yarn strands are arranged in advance according to the specific functional performance requirements of the final article before the bonding material is applied. This preliminary arrangement allows the fabric structure to be optimized for directional elasticities and strengths needed in specific applications (such as compression gear or footwear) while maintaining a simplified manufacturing process where the bonding material is then applied to complete the structure.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The fabric structure is designed with dynamic adaptability where the primary yarn strands can be arranged in different configurations to meet varying functional demands across different applications. The bonding material is then applied to lock in this dynamically optimized arrangement, allowing the same manufacturing process to produce fabrics optimized for different functional requirements rather than being constrained to a single fixed intrinsic structure.

Inventive Principle:
Principle #15Dynamics

4Strength

If additional reinforcing cables or secondary fabric sections are applied to meet functional demands, then performance requirements are satisfied, but material usage and weight increase

Engineering Contradiction:
Improvedirectional strength and elasticityVSAvoidarticle weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

Instead of applying additional reinforcing cables or secondary fabric sections throughout the entire article, the bonding material is applied selectively at specific locations where reinforcement is needed to meet functional strength and elasticity requirements. This localized reinforcement approach achieves the necessary directional strength properties without the excessive weight that would result from uniform reinforcement throughout the entire fabric structure.

Inventive Principle:
Principle #3Local quality

AI summary

A method of creating an engineered textile (200) includes placing a yarn-wound jig (70) on an upper surface of a substrate (216), selectively printing or extruding a bonding material (54) across the plurality of arranged yarn strands (52), solidifying the bonding material (54) to bond adjacent ones of the plurality of arranged yarn strands (52) together and form a bound plurality of arranged yarn strands (52), and removing the bound plurality of arranged yarn strands (52) from the substrate (216) and the frame (70).
