Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic control systems for roulette wheels struggle to efficiently monitor and ensure the correctness of non-traditional roulette games with varied color schemes, as they rely on specific color contrasts that may not be effective for all configurations.
Innovation Solution
The implementation of a roulette wheel with digital optical sensors using LED and laser transmitters and receivers, combined with a data collection and processing unit, to detect the angular position of the wheel and ball with high precision, and a levelling system to maintain stability, along with additional sensors for anomaly detection and real-time data analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional electronic control systems use specific color contrast detection (e.g., blue/yellow light for white ball), then detection accuracy is improved for traditional roulette wheels, but the system becomes ineffective for non-traditional roulette wheels with varied color schemes
Solution Approach 1:
The patent uses LED light sources that can emit light at different wavelengths (colors) - specifically blue or yellow light for ball detection, and red light for wheel position detection. The system adapts the color/wavelength of illuminating light based on the ball and wheel configuration to maximize color contrast and detection accuracy for both traditional and non-traditional roulette wheels
Solution Approach 2:
The electronic control system dynamically adjusts the wavelength/color of LED light sources based on the detected ball position and wheel configuration. The system switches between different light colors (blue/yellow for ball, red for wheel) to optimize contrast detection for various roulette wheel designs, making the system adaptable to non-traditional color schemes
2Adaptability or versatility
If multiple LED light sources with different wavelengths are used to detect both ball position and wheel position, then detection versatility is improved, but device complexity increases
Solution Approach 1:
The patent incorporates multiple LED light sources (at least three) with different wavelengths into a single detection device that can perform multiple functions: detecting ball position using blue or yellow light, detecting wheel position using red light, and adapting to different wheel color schemes. This multi-functional approach consolidates what could be separate systems into one unified device
Solution Approach 2:
The patent merges multiple light sources (blue/yellow LEDs for ball detection, red LEDs for wheel detection) and multiple detectors into a single integrated detection device installed on the roulette rim. This consolidation reduces the overall system complexity compared to having separate detection systems for ball position and wheel position

Function Achieved in This Case
Enables rapid and accurate monitoring of the game progress, ensuring correctness even with non-traditional wheel designs by providing precise detection of wheel and ball positions, speed, and direction, while maintaining stability and detecting anomalies, thus ensuring compliance with game regulations.
Implementation Method 1
LED light sources adapted to emit non-coherent light in the visible range at one or more specific wavelengths which are predetermined depending on the relative chrominance parameter for the ball and the rotating wheel, with a view to maximizing the colour contrast between the ball and background
Implementation Method 2
detector devices adapted to receive the reflections of a controlled light beam which are produced by the outer numbered ring and the inner ring provided with pockets able to receive the ball, forming part of the roulette wheel, and by the ball itself
Implementation Method 3
laser transmitters and receivers, combined with a data collection and processing unit, to detect the angular position of the wheel and ball with high precision
