Fiber-Bound Engineered Materials via Entanglement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for forming engineered articles from stock materials involve cutting, layering, and combining discrete pieces, which increase costs, bulk, waste, and limit design options due to the uniformity of stock materials.
Innovation Solution
Fiber-bound engineered materials are created by entangling fibers to form a non-uniform material with specific functional characteristics at intended locations, eliminating the need for supplemental adhesives or connections through the use of scrims and varying fiber manipulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stock materials are cut into individual pieces and layered to form engineered articles, then design flexibility is improved, but manufacturing cost increases
Solution Approach 1:
The patent divides the continuous fiber layer into different functional zones with distinct characteristics (e.g., different fiber types, densities, or orientations) to create design flexibility without cutting the material into separate pieces. This allows regional customization within a single continuous material structure.
Solution Approach 2:
The invention implements local quality by varying fiber properties (such as fiber type, length, orientation, or density) at different locations within the continuous layer to provide location-specific functional characteristics, eliminating the need to assemble multiple discrete pieces with different properties.
2Adaptability or versatility
If discrete pieces of stock material are layered and combined, then functional characteristics can be customized, but material waste increases
Solution Approach 1:
The continuous fiber layer is segmented into functional zones during the forming process itself, allowing different regions to have different characteristics without requiring separate material pieces. This eliminates waste associated with cutting and assembling discrete components.
Solution Approach 2:
The fiber layer is prepared with predetermined regional variations in fiber properties before the article forming process, enabling functional customization to be built-in from the start rather than achieved through post-processing assembly of discrete pieces, thereby reducing material waste.
3Adaptability or versatility
If multiple discrete material pieces are assembled, then design complexity increases, but manufacturing time increases
Solution Approach 1:
The patent combines multiple functional zones and material variations into a single continuous fiber layer structure, merging what would traditionally require multiple discrete pieces into one integrated material that can be formed directly into the final article shape, thereby reducing manufacturing time.
Solution Approach 2:
The fiber layer is pre-configured with all necessary functional variations and regional characteristics before the article forming process, so that during forming, the material simply needs to be shaped rather than assembled from multiple pieces, significantly reducing manufacturing time.
4Ease of manufacture
If uniform stock material is used throughout, then manufacturing is simpler, but design options are limited
Solution Approach 1:
The invention implements local quality by creating regional variations in fiber properties (such as fiber type, orientation, density, or length) within the continuous layer, allowing different functional characteristics at different locations while maintaining the simplicity of a single continuous material structure during manufacturing.
Solution Approach 2:
The fiber layer is designed with dynamic characteristics that can be activated or expressed differently during the forming process, allowing uniform material to be transformed into non-uniform functional zones through controlled manipulation during article formation, thereby expanding design options without complicating manufacturing.

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).
