Solution Overview

Problem

Traditional methods of forming engineered articles from stock materials often result in increased costs, bulk, waste, and limited design options due to the need for cutting, layering, and combining discrete pieces, which can introduce inefficiencies and unintended characteristics.

Innovation Solution

A fiber-bound engineered material is created through entangling fiber layers with additional fibers, allowing for non-uniform functional characteristics without the use of adhesives or interlacing, and incorporating scrim materials to achieve specific properties at intended locations within the article.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If stock materials are cut into individual pieces and layered/combined to form engineered articles, then design options can be achieved, but costs increase, bulk increases, waste increases, and manufacturing complexity increases

Engineering Contradiction:
Improvedesign optionsVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the continuous fiber layer into different zones with distinct functional characteristics. Each zone contains specifically positioned fibers or scrim materials that provide targeted properties (e.g., moisture transport, structural support) at intended locations within the final article, eliminating the need to cut and layer multiple discrete pieces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by creating non-uniform fiber distribution and properties within the continuous layer. Different regions of the fiber layer are engineered with specific fiber types, densities, and configurations to provide location-specific functions such as moisture wicking in certain areas and structural integrity in others, all from a single continuous material.

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If stock materials are cut into individual pieces and layered/combined, then engineered characteristics can be achieved, but material waste increases

Engineering Contradiction:
Improveengineered characteristicsVSAvoidmaterial waste
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The patent applies preliminary action by pre-positioning fibers and scrim materials in their final intended locations within the continuous fiber layer before the lapping process. This pre-arrangement ensures that engineered characteristics are built-in during manufacturing rather than requiring post-processing cutting and assembly, thereby eliminating material waste from off-cuts and trimmings.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If discrete pieces are layered and combined, then functional characteristics can be achieved, but costs increase

Engineering Contradiction:
Improvefunctional characteristicsVSAvoidmanufacturing cost
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent merges multiple functions and material layers into a single continuous fiber layer. By incorporating different fiber types, densities, and scrim materials throughout the continuous structure, the patent eliminates the need for multiple separate manufacturing steps involving cutting, layering, and bonding discrete pieces, thereby reducing labor, equipment, and material costs while maintaining functional characteristics.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A method of forming a fiber-bound engineered material utilizing carrier screens is provided that imparts an intended characteristic at an intended relative location. Also provided are articles formed of fiber-bound engineered materials manufactured utilizing carrier screens. A fiber layer is placed adjacent at least one carrier screen and entangled with additional fibers in a manner to create a non-uniform engineered material. The lack of uniformity of a fiber-bound engineered material may be accomplished through manipulation of the fibers and/or through fiber binding a scrim. The fiber layer binds with additional fibers through entanglement such that a mechanical connection between the entangled fibers is provided. This entanglement allows the fibers to bind without supplemental adhesives, interlacing, or connections.
