Solution Overview

Problem

Traditional mechanical slot machines lack the entertainment value of video-based slot machines, as players are deterred by the difference in appearance of simulated reels, leading to a need for a gaming machine that combines video-based capabilities with the simplistic rotation of mechanical reels.

Innovation Solution

A gaming machine featuring a transparent curved display layer with a video display projecting moving images of symbols that simulate mechanical reels, including imperfections, to create a more engaging and realistic experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If video-based slot machines are used to provide complex graphical images and animations, then entertainment value is improved, but the appearance of simulated reels becomes less realistic compared to mechanical reels

Engineering Contradiction:
Improveentertainment valueVSAvoidreel appearance realism
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies the copying principle by projecting video images onto a transparent curved layer that physically replicates the appearance of mechanical reels. The video display generates images of symbols that are projected through the curved transparent layer, creating a visual copy of mechanical reel behavior while maintaining the flexibility of video-based systems. This allows the simulated reels to closely mimic the appearance and motion characteristics of traditional mechanical reels.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent substitutes the mechanical reel system with a video projection system that projects images onto a transparent curved layer. Instead of using actual rotating mechanical reels with physical symbols, the invention uses a video display device to generate and project images that simulate reel rotation and symbol display, thereby replacing the mechanical system with an electronic one while preserving the visual appearance.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If traditional mechanical reels are used, then the simplistic rotation and realistic appearance are maintained, but entertainment value and flexibility in game design are reduced

Engineering Contradiction:
Improvereel appearance realismVSAvoidentertainment value
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies the universality principle by creating a system that combines the visual appearance of mechanical reels with the functional capabilities of video-based systems. The transparent curved layer with video projection serves multiple functions: it maintains the realistic appearance of mechanical reels while enabling complex graphical images, animations, and flexible game design. This multi-functional approach allows the system to satisfy both traditionalists who value realistic reel appearance and modern players who expect enhanced entertainment features.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses the transparent curved layer as an intermediary between the video display and the player's view. This intermediary element allows video images to be projected while maintaining the visual characteristics of mechanical reels. The curved transparent layer acts as a mediator that translates electronic video signals into a format that resembles traditional mechanical reel display, thereby bridging the gap between old and new technologies.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If video displays are used to simulate mechanical reels, then flexibility in game design is improved, but the simulated reels differ in appearance from standard mechanical reels

Engineering Contradiction:
Improvegame design flexibilityVSAvoidreel appearance
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The patent applies the curvature principle by using a transparent curved layer instead of a flat display surface. The curved shape of the transparent layer mimics the cylindrical shape of traditional mechanical reels, creating a more authentic appearance. This curvature allows the projected video images to wrap around the surface in a manner that resembles how symbols are displayed on actual rotating mechanical reels, thereby improving the visual resemblance while maintaining video-based flexibility.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

A gaming machine for playing a wagering game includes a housing having a display region, a curved transparent layer located in the display region, and a video display. The video display is located behind the transparent layer for projecting moving images onto the transparent layer. The images including a plurality of symbols that indicate a randomly selected outcome of the wagering game. The curved transparent layer can be moving as well. Environmental mapping may be used to sense the location of the player and/or the ambient lighting surrounding the gaming machine and alter the images based on the sensing. The altering may include spectral highlights, shading, and the parallax effect. The video images may further include imperfections normally found in mechanical reel strips. The gaming machine provides video images that more closely simulate the look of traditional mechanical reels.
