Solution Overview

Problem

Existing roulette gaming machines require complex systems for ball collection and discharge, leading to increased costs and maintenance complexity, and hinder player viewing angles due to the design of ball receiving parts and roulette plates.

Innovation Solution

A roulette device that uses compressed air to repeatedly roll a ball on a roulette plate without the need for ball collection or discharge systems, featuring ball receiving parts with a depth shorter than the ball diameter and a bank passage with inclined planes, allowing easy ball detection and reduced maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ball receiving parts are formed with predetermined depth to cover part of the ball, then the ball can be collected, but the roulette plate height must be increased which hinders player viewing

Engineering Contradiction:
Improveball collectionVSAvoidroulette plate height
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

The patent extracts the ball collection function from the ball receiving parts by providing a separate ball collecting part. The ball passing holes allow balls to be discharged from the ball receiving parts, and the dedicated ball collecting part receives these discharged balls. This separation enables the ball receiving parts to have reduced depth while maintaining ball collection capability through the external collecting part.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces ball passing holes as an intermediary mechanism between the ball receiving parts and the ball collecting part. These holes serve as a mediator that enables ball transfer from the receiving parts to the collecting part, allowing the receiving parts to be shallower while still achieving effective ball collection through the intermediary passage.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Volume of stationary object

If ball passing holes are formed on each ball receiving part for ball collection, then the system size is reduced, but complex operating units such as shutters are required increasing cost and maintenance

Engineering Contradiction:
Improvesystem sizeVSAvoidoperating unit complexity
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The patent implements a passive ball discharge mechanism where balls are discharged from the ball receiving parts through ball passing holes using gravity and the natural rolling motion of the balls themselves. No active operating units such as shutters or motors are required at each ball receiving part. The system uses the balls' own kinetic energy and gravitational force to achieve discharge, eliminating the need for complex localized control mechanisms.

Inventive Principle:
Principle #25Self-service

3Reliability

If ball receiving parts have operating units like shutters for opening/closing, then ball collection is enabled, but cost increases and game may stop due to breakdown

Engineering Contradiction:
Improveball collection controlVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent removes the operating units (shutters, motors, sensors) from each ball receiving part and extracts the ball collection control function to a centralized ball collecting part. The ball passing holes remain open and passive, eliminating per-part operating units. Only simple structural elements are needed at each receiving part, significantly reducing manufacturing cost and potential failure points.

Inventive Principle:
Principle #2Taking out (Extraction)

4Productivity

If roulette plate has discharge opening for ball discharge, then ball can be returned to roulette plate, but plate height must be higher than predetermined height

Engineering Contradiction:
Improveball discharge functionVSAvoidroulette plate height
Core Design Contradiction:
ProductivityVSLength of stationary object

Solution Approach 1:

The patent resolves the height constraint by changing the spatial arrangement from a vertical discharge approach to a horizontal/external collection approach. Instead of discharging balls upward through openings in the roulette plate (which would require high plate height), the system uses ball passing holes to discharge balls laterally to an external ball collecting part positioned at a lower elevation, enabling ball return without increasing plate height.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
