Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light-emitting composite stones suffer from dark areas and uneven light emission due to the placement of light guides and LEDs, leading to increased manufacturing costs and poor heat dissipation.
Innovation Solution
A light-emitting composite stone design featuring a transparent stone with multiple reflection members and light guides, including a first and second light guide, inclined cuts, and reflection members at specific angles to distribute light uniformly across the stone, eliminating dark areas and enhancing light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If additional LEDs are disposed in the groove to increase light emitting to edges, then light emitting area is improved, but light uniformity deteriorates and manufacturing cost increases
Solution Approach 1:
The patent introduces a light guide as an intermediary component between the LED and the stone surface. The light guide receives light from the LED and distributes it uniformly across the entire stone surface including edges, eliminating the need for additional LEDs while maintaining light uniformity and expanding the effective light emitting area.
2Area of stationary object
If additional LEDs are disposed in the groove to increase light emitting, then light emitting area is improved, but manufacturing cost increases
Solution Approach 1:
The light guide serves multiple functions: it acts as a light distribution medium, an optical waveguide, and a structural component that can be integrated into the stone product design. This multi-functionality eliminates the need for additional LEDs and reduces manufacturing complexity and cost while achieving uniform light emission across the entire surface.
3Area of stationary object
If additional LEDs are disposed in the groove, then light emitting area is improved, but heat dissipation deteriorates
Solution Approach 1:
The patent extracts the heat-generating function from the light emission system by using a single LED combined with a light guide, rather than multiple LEDs. This reduces the total heat generation in the groove area while maintaining or improving light distribution, thereby improving heat dissipation performance.
4Illumination intensity
If light guide is disposed in the groove, then light emission is provided, but dark areas appear on edges of stone member
Solution Approach 1:
The patent transitions from a localized light emission approach (LEDs in grooves) to a distributed light emission approach using a light guide that extends light across the entire surface area of the stone, including edges. This dimensional expansion of light distribution eliminates dark areas by bringing illumination to previously unreachable regions.
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 design ensures uniform illumination of both the edge stone and transparent stone, increasing the light-emitting effect while simplifying the replacement of malfunctioned LEDs and reducing manufacturing costs.
Implementation Method 1
a first reflection member having an inclined angle of 45-degree disposed on a bottom of the inclined cut, the first reflection member configured to reflect light emitted by the light-emitting member into the first light guide to generate horizontal rays
Implementation Method 2
a second reflection member disposed on a top of the first vertical light guide for reflecting portions of light emitted by the light-emitting member to a top edge of one side of the transparent stone
