Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illumination devices in gaming machine islands lack variability in illumination effects due to fixed light guide plates, making it difficult to create distinctive and engaging presentations.
Innovation Solution
An illumination device with rotatable light guide plates and light source units, controlled by a rotational drive unit and a control unit, allowing for adjustable rotation speed, direction, and duration, as well as lighting patterns, to enhance the presentation and illumination effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light guide plates are fixed in place, then the structure is simple and stable, but the illumination effect is always the same and it is difficult to make it distinctive
Solution Approach 1:
The light guide plates are made rotatable around a rotation axis instead of being fixed, allowing them to change orientation dynamically. This enables the illumination device to display light from different surfaces (incident surface, exit surface, end surfaces) by rotating to different angles, creating varied illumination effects without requiring multiple separate devices.
Solution Approach 2:
The invention adds a rotational dimension to the previously static light guide plate structure. By introducing rotation around an axis, the system transitions from a two-dimensional fixed arrangement to a three-dimensional dynamic configuration, enabling light emission from multiple surfaces that were previously not simultaneously可利用able.
2Adaptability or versatility
If light guide plates are made rotatable, then a wide range of presentations are possible, but the device complexity increases
Solution Approach 1:
The same light guide plate structure serves multiple functions by rotating to different positions. A single light guide plate can display light from its incident surface, exit surface, and various end surfaces depending on its rotational angle, eliminating the need for multiple separate light guide plates or illumination devices to achieve the same effect.
Solution Approach 2:
The orientation angle of the light guide plates is changed as a controllable parameter. By adjusting the rotation angle, the system can selectively present different surfaces of the light guide plates to observers or cameras, enabling varied presentations through parameter adjustment rather than structural redesign.
3Ease of operation
If rotational drive unit is added, then dynamic control of light guide plates is achieved, but the device complexity and cost increase
Solution Approach 1:
The invention replaces complex mechanical positioning systems with a simpler rotational drive mechanism. Instead of using multiple actuators to position light guide plates in three-dimensional space, a single rotational drive unit around a central axis achieves the same effect with fewer components, reducing overall mechanical complexity.

AI summary
An illumination device (10) is attached to a gaming machine island including a plurality of gaming machines (40), and comprises LEDs (21a) that emit light, light guide plates (20), a rotating body (23), a plate-shaped member (24), a motor (31), a lower case (13), and a control unit 17. A plurality of light guide plates 20 are attached to the plate-shaped member 24. The light guide plates 20 each have an end surface 20a on which the light emitted from the LEDs 21a is incident, and a flat surface 20b from which the incident light is emitted. The rotating body 23 and the plate-shaped member 24 hold an LED board 21 and the light guide plates 20. The motor 31 rotates the rotating body 23 in the desired direction. The lower case 13 is provided with the motor 31, is connected to the rotating body 23 and the plate-shaped member 24 in a relatively rotatable state, and is installed on a gaming machine island that includes gaming machines 40. The control unit 17 controls the rotation of the rotating body 23 and the plate-shaped member 24 by the motor 31.
