Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light guides with high transparency materials and diffusing agents suffer from uneven brightness and glare, leading to reduced light projection distance and range, and a less aesthetically pleasing visual effect, which complicates manufacturing and consumer appeal.
Innovation Solution
A light guide device made of a diffusing agent-free, transmissive material with continuously connected and irregularly configured components that refract light to achieve uniform brightness and increase projection distance and range, using a planar light-incident surface and varying light-emitting surface angles to enhance glare effects and reduce manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light diffusing agent is added to the light guide material, then brightness uniformity is improved, but light projection distance and range are shortened
Solution Approach 1:
The patent removes the light diffusing agent from the light guide material, using only high transparency materials. This extraction eliminates the multiple refractions caused by diffusing agents that soften light and cause fogging, thereby maintaining long light projection distance while achieving brightness uniformity through the irregular configuration of light guide components instead.
Solution Approach 2:
The patent employs irregularly configured light guide components with non-uniform shapes and varying light-emitting surface angles rather than symmetric, regular structures. This asymmetric design creates uneven light projection patterns that guide light to the entire area, achieving brightness uniformity without requiring light diffusing agents that would shorten projection distance.
2Illumination intensity
If a light diffusing agent is added to the light guide material, then brightness uniformity is improved, but the lighting effect becomes less beautiful
Solution Approach 1:
The patent extracts the light diffusing agent from the material composition, eliminating the fogging effect and multiple refractions that degrade visual quality. The high transparency material combined with irregular component configuration achieves both brightness uniformity and gorgeous light refraction effects without aesthetic degradation.
Solution Approach 2:
The patent utilizes irregular, curved configurations of light guide components with varying light-emitting surfaces at different angles. These non-linear, organic shapes create beautiful aurora-like glare effects and gorgeous light refraction patterns, enhancing aesthetic quality while maintaining brightness uniformity through the irregular geometry rather than through diffusing agents.
3Ease of manufacture
If the light guide is made as a flat strip, then manufacturing is simplified, but the optical visual effect becomes tedious
Solution Approach 1:
The patent transitions from simple flat strip geometry to irregularly configured light guide components with varying shapes and light-emitting surfaces. This asymmetric design maintains manufacturing feasibility through molding processes while creating diverse, gorgeous light refraction effects that eliminate visual monotony and enhance aesthetic appeal.
Solution Approach 2:
The patent divides the light guide into multiple continuously connected irregularly configured components rather than using a single flat strip. Each component has its own light-emitting surfaces at different angles, and their continuous connection maintains structural integrity for simplified manufacturing while their irregular configurations collectively produce rich, varied optical visual effects.
4Use of energy by moving object
If light-emitting devices are positioned to face the light guide directly, then light emission is maximized, but uneven brightness and glare occur
Solution Approach 1:
The patent positions light-emitting devices to face specific local areas of the irregularly configured light guide components rather than uniformly illuminating the entire guide. The varying light-emitting surface angles of different components redirect light locally to achieve overall brightness uniformity while preventing direct glare from concentrated light sources, maintaining emission efficiency without uneven brightness.
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 provides improved brightness uniformity and extended light projection range, eliminating glare and fogging, while reducing manufacturing costs and enhancing the aesthetic appeal of light-emitting effects, making the product more attractive to consumers.
Implementation Method 1
the light guide components guides the light to the entire light guide device... Because the light guide device is not added with a light diffusion agent and can work with the light guide components to unevenly output the light emitted by the light-emitting devices, it effectively increases the light projection distance and range
Implementation Method 2
Each light-emitting surface defines with the base a respective contained angle that causes a glare effect when light passes through the respective light guide component
