Solution Overview
Problem
Existing braided fibers used in furniture production lack the tactile and optical resemblance to natural fibers, and their haptic and optical properties are not adequately enhanced for improved perception and production simplicity.
Innovation Solution
The braided fibers feature triangular cross-sectional elevations, which can be arranged parallel to each other without gaps, with varying side lengths and colors, to create a surface structure that mimics natural fibers, providing enhanced abrasion resistance and iridescent visual effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If parallel ribs with gaps are used in the woven fiber, then the structure resembles natural fiber visually, but the haptic texture and abrasion resistance are insufficient
Solution Approach 1:
The patent applies curvature by using rounded projections instead of sharp ribs, and specifically implements triangular cross-sections with curved surfaces. This curvature provides both the visual resemblance to natural fibers and the tactile smoothness needed for improved haptic properties while maintaining abrasion resistance through the rounded geometry that distributes wear.
2Shape
If a fiber structure is applied to the surface to resemble natural rattan, then the visual appearance improves, but the manufacturing complexity increases
Solution Approach 1:
The patent merges the base body and surface fiber structure into a single integrated extrusion process. The triangular projections are formed directly during extrusion of the base material, eliminating the need for separate surface application steps. This combining of structure formation and surface texturing in one process reduces manufacturing complexity while achieving the natural fiber appearance.
3Illumination intensity
If triangular projections with varying side lengths are used, then the iridescent visual effect and haptic texture improve, but the manufacturing precision requirements increase
Solution Approach 1:
The patent utilizes parameter changes by varying the side lengths of triangular projections to create different viewing angles that produce iridescent effects. The extrusion process parameters are adjusted to create these dimensional variations, which generate the optical phenomenon of color change with viewing angle while maintaining manufacturability through controlled parameter variation rather than complex geometric forms.

Function Achieved in This Case

AI summary
The invention relates to a woven fiber (1), particularly for the manufacture of furniture and/or furniture components, comprising a base body (2) produced by extrusion from a plastic material with a flat cross-section, the width of which is a multiple of its height, and wherein the base body (2) has at least one broad side with projections (3) extending parallel to each other. To create a woven fiber (1) that closely resembles a natural fiber in its haptic and visual appearance and is easy to manufacture, the invention proposes that the projections (3) have a triangular cross-section. The invention further relates to a method for producing such a woven fiber (1).
