Solution Overview

Problem

Existing translucent building and furniture components made with embedded optical fibers suffer from limited light translucency and strength, restricting design flexibility and production simplicity.

Innovation Solution

A translucent object is created using a hardenable cast material with optical fibers arranged in a three-dimensional structural cage, providing high strength and flexible design options, where the cast material envelops the cage and optical fibers, allowing light to be transported from one surface point to another, and using ultra-high performance concrete for enhanced strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If optical fibers are embedded in cast material layers using conventional layer-by-layer construction, then the component achieves some level of translucency, but the light translucency and density of light guides remain limited

Engineering Contradiction:
Improvelight translucencyVSAvoidconstruction complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent transitions from conventional layer-by-layer construction to a three-dimensional structural cage framework. Optical fibers are arranged in a 3D spatial configuration within the cage, allowing light to be transported across the component in multiple directions simultaneously, significantly enhancing light translucency while reducing construction complexity through integrated molding

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent combines optical fibers with cast material (such as concrete or polymer) to create a composite structure. The optical fibers are embedded within the cast material that forms the structural cage, creating a composite material system that provides both structural integrity and enhanced light transmission properties

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If optical fibers are arranged in ordered patterns in cast objects, then the component achieves structural integrity, but design flexibility and luminescence are limited

Engineering Contradiction:
Improvedesign flexibilityVSAvoidstructural integrity
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The patent applies different arrangements of optical fibers within different regions of the structural cage. The fibers can be concentrated in certain areas for enhanced luminescence or arranged sparsely in other areas for structural considerations, allowing localized optimization of both design flexibility and structural integrity

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent enables dynamic design configurations where optical fibers can be arranged in various patterns (ordered, random, concentrated, distributed) depending on the desired luminescence effect and structural requirements, providing adaptability in design while maintaining structural integrity through the cage framework

Inventive Principle:
Principle #15Dynamics

3Illumination intensity

If multiple layers of optical fibers and cast material are stacked to increase light guidance, then light translucency improves slightly, but the construction process becomes more complex and time-consuming

Engineering Contradiction:
Improvelight translucencyVSAvoidproduction efficiency
Core Design Contradiction:
Illumination intensityVSProductivity

Solution Approach 1:

The patent pre-arranges optical fibers in a three-dimensional structural cage framework before casting the surrounding material. This preliminary configuration of fibers in the desired 3D pattern eliminates the need for time-consuming layer-by-layer stacking and subsequent assembly operations, significantly improving production efficiency while achieving superior light translucency

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent merges the optical fiber arrangement structure with the cast material forming process into a single integrated operation. The fibers are positioned in the structural cage, and the cast material is then poured to envelop both the cage and fibers simultaneously, combining what would otherwise be separate sequential steps into one efficient production process

Inventive Principle:
Principle #5Merging (Combining)

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 high light translucency and strength, enabling flexible design possibilities while maintaining production simplicity and cost-effectiveness, with light transmission of at least 75% and comparable mechanical properties to non-translucent objects.

Implementation Method 1

The optical fibers are arranged in a three-dimensional structural cage formed by a meshwork, wherein the optical fibers pass through mesh of the meshwork such that the ends of said optical fibers protrude sideways out of mesh of the cage and at different points of the object... In this way, the light may be transported from one point on the surface of the object to another point on the surface
