Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional gaming machines with liquid crystal display devices have limitations in image representation due to flat screens, restricted size, limited brightness control, and lack of decorativeness, resulting in two-dimensional and confined image effects.
Innovation Solution
A gaming machine design featuring a curved screen with a projector that projects light onto the back surface, allowing for three-dimensional image representation without a frame, broader display area, and varied brightness through light-transmissive materials and structures, including a light diffusion member and half-mirror, to create diverse and engaging visuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a liquid crystal display device is used, then the screen can display images, but the screen is flat and the effect representation by images is limited
Solution Approach 1:
The patent applies curvature to the screen surface by using a projection-type display that projects images onto a curved or spherical surface rather than a flat liquid crystal display. This curvature enables three-dimensional image representation and enhances the visual effect, directly resolving the contradiction between maintaining a simple display structure and achieving diverse image representation.
2Area of stationary object
If the liquid crystal display device is provided inside an exterior member, then the device is protected, but the size of the screen is restricted by the exterior member or frame
Solution Approach 1:
The patent extracts the display function from a conventional framed liquid crystal display and implements it through a projection system that can utilize the entire exterior member surface as the display area. This eliminates the restriction of frames and allows the screen size to extend to the full boundaries of the exterior member, maximizing the display area while maintaining integration.
3Area of stationary object
If a front door with hinge is provided, then the door can open and close, but the hinge narrows the area for displaying images
Solution Approach 1:
The patent uses a curved or spherical projection surface that can accommodate door movement without requiring traditional hinges. The projection surface can be positioned on the door in a way that utilizes the entire available area, including regions that would otherwise be occupied by hinge mechanisms, thereby maximizing the image display area while maintaining door operability.
4Shape
If the liquid crystal display is flat, then reflection is restrained, but the display lacks decorativeness and three-dimensional effect
Solution Approach 1:
The patent employs a curved or spherical projection surface that inherently controls light reflection through its geometry. The curved surface disperses reflected light in multiple directions, reducing glare and unwanted reflections while simultaneously providing three-dimensional visual effects and enhanced decorativeness, thus resolving the contradiction between reflection control and visual appeal.

Function Achieved in This Case
The solution enables the gaming machine to provide diverse and engaging three-dimensional image representation, expanding the display area and enhancing visual effects with varied brightness and depth, overcoming the limitations of traditional liquid crystal display devices.
Implementation Method 1
a screen (e.g., screen unit 10040 and the like) whose surface at least partially includes a curved surface (e.g., curved portion 10042 and the like); a projector (e.g., projector 10020 and the like) accommodated inside a casing, which is configured to project light to the screen, wherein the light projected by the projector is incident on a back surface side of the screen from the inside of the casing; the screen lets the light incident on the back surface side of the screen pass to the front surface side of the screen

AI summary
There is provided a gaming machine capable of providing diverse type of image representation. The gaming machine 1 includes: a screen unit 10040 whose surface at least partially includes curved portions 10042; and a projector 10020 accommodated inside a casing 2, which is configured to project light to the screen unit 10040. Light projected by the projector 10020 is incident on a back surface side of the screen unit 10040 from the inside of the casing 2. The screen unit 10040 lets the light incident on the back surface side of the screen unit 10040 pass the screen unit 10040, thereby enabling displaying of an image on the front surface side of the screen unit 10040 positioned on the surface of the casing 2.
