Problem

Existing roulette gaming systems face challenges in ensuring secure and unpredictable ball launching, quick recovery of the ball, and maintaining game excitement, with limitations in controlling ball speed and direction, leading to potential manipulation and lengthy downtimes.

Innovation Solution

A ball launcher system with an airflow generator controlled by a controller, using variable airflow mass, speed, and direction, combined with a ball shuttle mechanism for precise launch timing, and sensors for real-time ball speed detection to adjust airflow parameters, allowing for precise control of ball speed and spin, and quick recovery of the ball.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple ball launch mechanism is used, then device complexity is reduced, but ball speed control precision and launch predictability deteriorate

Engineering Contradiction:
Improveball launch mechanism complexityVSAvoidball speed control precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent employs a pneumatic launch mechanism where compressed air is directed through a launch tube to propel the ball. This pneumatic system provides precise control over ball speed and launch timing through regulated airflow, while maintaining relatively simple device architecture compared to mechanical alternatives.

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The system controls ball launch parameters by varying airflow characteristics (pressure, duration, direction) rather than using complex mechanical adjustments. The controller modulates pneumatic parameters to achieve desired ball speeds and trajectories, simplifying the overall mechanism while maintaining precision.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If fixed airflow parameters are used for ball launch, then device complexity is reduced, but adaptability to different game conditions deteriorates

Engineering Contradiction:
Improveairflow control system complexityVSAvoidball launch adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic airflow control where the pneumatic system parameters (pressure, flow rate, duration) are continuously adjusted based on real-time game conditions, ball position, and desired trajectory. This dynamic adaptation allows the same device to handle various game scenarios without increasing fundamental system complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms that monitor ball position, launch conditions, and game state, then use this information to adjust airflow parameters for subsequent launches. This closed-loop control enables adaptability while keeping the device architecture relatively simple through intelligent control algorithms.

Inventive Principle:
Principle #23Feedback

3Device complexity

If manual ball recovery and relaunch preparation is used, then device complexity is reduced, but game downtime increases

Engineering Contradiction:
Improveball recovery system complexityVSAvoidgame downtime
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent implements an automated ball recovery and relaunch system where the pneumatic mechanism automatically retrieves the ball after it completes its trajectory and prepares it for the next launch without human intervention. The system self-manages the transition between game rounds, minimizing downtime while maintaining simple device architecture through automation of routine tasks.

Inventive Principle:
Principle #25Self-service

4Ease of operation

If predictable ball launch timing is used, then ease of operation is improved, but game security against manipulation deteriorates

Engineering Contradiction:
Improveball launch operation simplicityVSAvoidgame security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system uses periodic or randomly varied launch timing rather than fixed predictable intervals. The controller introduces variability in launch timing while maintaining operational simplicity through automated control, preventing manipulation while keeping the system easy to operate through standardized procedures.

Inventive Principle:
Principle #19Periodic action

AI summary

The present invention relates to a roulette wheel apparatus, and in particular to a ball launcher for use in a gaming system such as a roulette wheel apparatus and roulette wheel apparatus comprising the ball launcher. The airflow generator for generating the airstream through the launch tube is controlled by an airflow controller adapted to reverse airflow direction and/or to cause airflow in a direction opposite to the ball moving direction when a detected ball speed is higher than a desired ball speed and/or the ball speed is to be decreased.
