Slanted Light Guide Plates for Multi-Angle Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative illumination devices for game machines primarily provide impactful visual effects only to users positioned directly in front, failing to engage nearby users effectively.
Innovation Solution
A decorative illumination device featuring slanted light guide plates with gaps, a window part open from multiple directions, and a mirror unit that reflects light, creating a three-dimensional visual effect and optical illusion, allowing the light emitting surfaces and outer edges to be visible from various angles, including from behind the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light emitting surface is oriented toward the front of the device, then the visual effect for users positioned in front is highly impactful, but users positioned beside or behind cannot see the light emitting surface
Solution Approach 1:
The patent transitions from a single-plane light emitting surface to a three-dimensional arrangement where multiple light guide plates are positioned at different angles and depths. This dimensional change allows light to be emitted toward the front, sides, and back simultaneously, enabling users from various positions to observe the illumination effects.
Solution Approach 2:
The patent divides the single light emitting surface into multiple segmented light guide plates, each oriented at different angles. This segmentation allows different portions of the light source to be visible from different directions, resolving the contradiction between front-facing impact and multi-angle visibility.
2Device complexity
If the light guide plates are arranged in a single plane, then the structure is simple, but the sense of depth and three-dimensional visual effect is limited
Solution Approach 1:
The patent arranges light guide plates in three-dimensional space with varying angles and depths rather than in a single plane. This creates overlapping light fields and multiple viewing perspectives, generating a strong sense of depth while maintaining reasonable structural complexity through modular assembly.
3Reliability
If the window part is closed, then the internal structure is protected, but users cannot see the light guide plates from multiple directions
Solution Approach 1:
The patent applies different properties to different parts of the housing: transparent or translucent window portions in areas requiring visibility (front, sides, back) and opaque protective covering in areas requiring structural protection. This local differentiation allows simultaneous achievement of protection and multi-directional observation.
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 enables highly impactful visual effects for users positioned beside or behind the device, enhancing engagement and creating a magical, depth-filled experience by reflecting and transmitting light to present a floating effect of the light guide plates.
Implementation Method 1
a plurality of light guide plates configured to reflect light entering therein from an end surface thereof with reflection surfaces formed in recesses thereon, and causing the light to be emitted from a light emitting surface
Implementation Method 2
a mirror part that functions to reflect light, with the mirror part provided on an inner wall that divides the internal space where the plurality of light guide plates is arranged
