Solution Overview

Problem

Mechanical roulette systems face issues with dust accumulation due to friction between the roulette ball and annular track, leading to reduced randomization, increased game cycle times, and maintenance downtime, while new players find the various betting options confusing, and existing technologies do not effectively address these issues.

Innovation Solution

A roulette machine with a controller that regulates inertial values, adjusts roulette wheel rotation velocity, and synchronizes game cycles using audio and visual effects, along with a system that optimizes betting window times and randomizes betting options based on risk levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the roulette ball is launched into the angled annular track, then the game cycle progresses and results are generated, but dust is generated through friction which reduces randomization and increases game cycle times

Engineering Contradiction:
Improvegame cycle throughputVSAvoiddust accumulation
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes dust from the annular track using a vacuum system with a vacuum source, vacuum port, and flexible wiper member that contacts the track surface to wipe away dust particles, thereby eliminating the harmful dust accumulation that reduces randomization and increases game cycle times

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a flexible wiper member as an intermediary element between the vacuum source and the annular track surface. This wiper member transfers dust particles to the vacuum system while maintaining contact with the rotating track, enabling continuous dust removal without interfering with the roulette ball's motion

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If dust accumulates in the annular track, then material erodes and dust is generated, but this reduces randomization of game results and increases game cycle times

Engineering Contradiction:
Improverandomization of resultsVSAvoidgame cycle time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The vacuum system continuously extracts dust particles from the annular track, preventing dust accumulation that would otherwise reduce randomization and increase game cycle times through increased friction and ball engagement with dust particles

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses sensors to detect dust levels and game cycle timing, providing feedback to the control system which adjusts vacuum activation and wiper pressure to maintain optimal randomization and game cycle timing by preventing dust accumulation

Inventive Principle:
Principle #23Feedback

3Loss of information

If new players are presented with all betting options, then complete betting information is provided, but players find the options confusing and require significant time to place bets

Engineering Contradiction:
Improvebetting information completenessVSAvoidbetting process simplicity
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent segments the betting interface into multiple categories (inside bets, outside bets, special bets) with clear visual organization and icons. Each category is separated and presented in a structured manner, allowing players to access complete betting information without being overwhelmed by the full range of options simultaneously

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system provides preliminary guidance and tooltips that appear before players make betting decisions, explaining betting options and rules in advance. The interface pre-organizes betting options by risk level and popularity, helping players make informed decisions more quickly without requiring them to process all information at once

Inventive Principle:
Principle #10Preliminary action

AI summary

A roulette wagering system is described that includes a roulette machine configured to operate live roulette games in which a roulette ball is launched into an angled annular track encircling a roulette wheel. A controller associated with the roulette machine may regulate one or more inertial values associated with the roulette ball. A bet close time of a betting window associated with the live roulette games may be determined based on the one or more inertial values associated. A rotation velocity of the roulette wheel may be adjusted subsequent to a bet close time of a live roulette games. Game cycle events may be detected using audio associated with the live roulette games and audible and/or visual effects may be generated based on the audio. A controller associated with the roulette machine may synchronizes the live roulette games operated by the roulette machine with live roulette games operated by one or more additional roulette machines. Bets may be placed based on a player selected betting risk level.
