Optical Fiber Interior Material Back-Surface Bundle Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional interior materials with optical fiber skin coatings face issues where the exposed optical fibers tend to hang and get damaged during handling, and existing solutions to manage them either increase production costs or hinder the placement of fastening portions near the design parting due to the fiber bundle's position on the back surface.
Innovation Solution
The interior material incorporates a bundle structure on the back surface of the base material to collect and manage the optical fibers, featuring standing walls with insertion holes or hook-shaped portions to securely house the fibers, allowing for easier collection and placement of fastening portions closer to the design parting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the optical fiber skin material is attached to the front surface of the base material, then the aesthetic appearance is improved, but the exposed optical fibers may hang and get damaged during handling
Solution Approach 1:
The patent moves the optical fiber bundle from a three-dimensional hanging state to a two-dimensional planar arrangement by embedding it within the base material plane. The bundle structure integrates the optical fibers into the back surface of the base material, transforming the spatial configuration from protruding to embedded, thereby preventing damage while maintaining aesthetic appearance.
2Reliability
If a corrugate tube is used to collect and protect the optical fiber bundle, then the optical fibers are protected from damage, but the production cost increases
Solution Approach 1:
The patent merges the optical fiber bundle collection function with the base material structure itself. Instead of using a separate corrugate tube, the base material's back surface is designed with an integrated bundle structure that collects and protects the optical fibers. This eliminates the need for additional protective components, reducing production cost while maintaining fiber protection.
Solution Approach 2:
The patent extracts the optical fiber bundle from the skin material and repositions it within the base material structure. By removing the fibers from the vulnerable external position and embedding them in the base material's bundle structure, the protection function is achieved without requiring separate protective tubes.
3Reliability
If the optical fiber skin material is extended to catch the bundle at the back surface, then the fibers are secured, but the fastening portion cannot be set near the parting in the design
Solution Approach 1:
The patent segments the base material back surface into distinct functional zones: a bundle structure region for collecting optical fibers and a fastening portion region for attachment operations. This spatial segmentation allows both the fiber bundle and fastening portion to coexist without interference, enabling the fastening portion to be positioned near the design parting while the bundle structure manages the fibers separately.

AI summary
The interior material includes a base material having a plate shape and a skin material covering a front surface of the base material, where the skin material has a woven fabric in which optical fibers are woven as constituent yarns. A bundle structure that collects a plurality of optical fibers exposed from the end portion of the skin material so as to lie along a back surface of the base material is provided at an end portion of the back surface of the base material.
