Two-Layer Textile Light Deflection Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative lighting arrangements with plain-weave construction fail to create visually appealing and effective light effects due to the visibility of the light source through fabric openings, lacking a design that maximizes light deflection and reflection while maintaining sufficient transparency.
Innovation Solution
A two-layer textile fabric structure with warp and weft threads arranged in straight lines, where the weft threads have higher density than warp threads, allowing for controlled light deflection and reflection to create a virtual image effect, using monofilament or twisted yarns made of polymeric or metal fibers, and embedded in a carrier structure for enhanced durability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a plain-weave construction with crossed warp and weft threads is used, then the fabric provides structural stability and coverage, but the light source becomes visible through the openings and light effects are not visually appealing
Solution Approach 1:
The fabric is divided into two separate layers: a warp thread layer and a weft thread layer. This segmentation allows each layer to be optimized independently for light deflection while maintaining structural integrity, eliminating the need for complex interlacing patterns that would compromise light effect quality.
Solution Approach 2:
The invention transitions from a single-layer two-dimensional weave to a three-dimensional two-layer structure. The weft thread layer is positioned at a distance from the warp thread layer, creating depth and enabling parallel thread orientation that maximizes light deflection without requiring complex surface patterns.
2Illumination intensity
If thread density is increased to improve light deflection, then light reflection is enhanced, but transparency and light passage are reduced
Solution Approach 1:
By segmenting the fabric into two layers with different thread densities, the invention allows the weft layer to have high thread density for effective light deflection while the warp layer maintains lower density to preserve transparency and allow sufficient light passage through the fabric.
Solution Approach 2:
Different regions of the fabric structure are assigned different thread densities optimized for their specific functions: the weft thread layer uses higher density for light deflection and reflection, while the warp thread layer uses lower density for maintaining transparency and structural framework.
3Illumination intensity
If threads are arranged in traditional plain-weave pattern, then fabric strength is maintained, but light beams are not deflected in a targeted manner to create virtual image effects
Solution Approach 1:
The fabric structure is segmented into two functional layers that work together: the warp layer provides the structural framework and the weft layer provides the light-deflecting surface. This segmentation enables targeted light deflection for virtual image creation while maintaining fabric strength through the warp layer's structural role.
Solution Approach 2:
By introducing the second layer at a distance from the first layer, the invention creates a three-dimensional structure that enables targeted light deflection angles. The parallel orientation of threads in both layers, positioned at appropriate distances, creates the geometric conditions necessary for virtual image effects while maintaining structural integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves striking light effects by producing a virtual image of the light source with increased image depth, providing both decorative and illuminating functions while maintaining sufficient transparency and flexibility, suitable for various applications including projection surfaces.
Implementation Method 1
the threads always rest against one another on the same (inner) thread half side, so that deflection of the impinging light beams to the visible side can be influenced in a targeted manner so as to achieve surprising light effects in the form of a rear-side virtual image
Implementation Method 2
deflection of the impinging light beams to the visible side can be influenced
