Solution Overview

Problem

Existing engineered articles formed from stock materials require cutting, layering, and combining discrete pieces, leading to increased costs, bulk, waste, and limited design options, while traditional adhesives and connections introduce inefficiencies and errors.

Innovation Solution

Fiber binding through entanglement creates a non-uniform engineered material by manipulating fibers and incorporating scrims, allowing for intended characteristics at specific locations without additional adhesives or connections.

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 and functional characteristics can be achieved, but costs increase, bulk increases, waste increases, and manufacturing efficiency decreases

Engineering Contradiction:
Improvedesign optionsVSAvoidmanufacturing efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies segmentation by dividing the engineered material into distinct fiber layers and scrim layers that can be independently designed and positioned. Each layer serves specific functional purposes (e.g., comfort, support, breathability), allowing customization of design options while maintaining manufacturing efficiency through a unified entanglement process rather than assembling pre-cut discrete pieces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges multiple functional layers (fiber layers and scrim layers) into a single integrated engineered material through hydroentanglement. This combining eliminates the need to assemble separate discrete pieces, reducing manufacturing steps, bulk, and waste while achieving the same design flexibility and functional characteristics.

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If traditional adhesives and connections are used to bond materials, then structural integrity is achieved, but manufacturing complexity increases, costs increase, and errors increase

Engineering Contradiction:
Improvestructural integrityVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent replaces mechanical bonding systems (adhesives, stitches, connectors) with a hydroentanglement process that uses high-pressure water jets to mechanically interlock fibers and scrims. This substitution achieves structural integrity without the complexity and potential errors associated with traditional adhesives and connections, while also eliminating associated costs and environmental concerns.

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

3Ease of manufacture

If uniform stock materials are used throughout, then manufacturing simplicity is maintained, but functional versatility and design customization are limited

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

Solution Approach 1:

The patent applies local quality by creating different fiber layers and scrim layers with distinct properties (e.g., different fiber types, densities, orientations, and functions) positioned at specific locations within the engineered material. This allows each region to provide tailored functional characteristics (comfort, support, breathability) while the overall manufacturing process remains relatively simple through the entanglement method.

Inventive Principle:
Principle #3Local quality

AI summary

A fiber-bound engineered material is provided that imparts an intended characteristic at an intended relative location. A fiber layer is 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. Variations in the fibers and/or inclusion of scrim materials prior to entanglement allows for an intended characteristic (e.g., a functional characteristic) at an intended relative location (e.g., a position determined by an article to be formed therefrom).
