Mechanical Reels With Dynamic Paytables for Multi-Game Play

Solution Overview

Problem

Existing gaming machines are limited by static mechanical reels that can only offer a single game, lacking versatility and player engagement due to fixed payline configurations and symbols, which restricts the variety of games that can be played without requiring hardware upgrades.

Innovation Solution

Utilizing a video transmissive display device positioned over mechanical reels to dynamically alter payline configurations and probabilities, enabling multiple games to be played with the same set of mechanical reels by selecting different paytables based on activated paylines, allowing for varied symbol combinations and awards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If new mechanical reels are provided for each game variation, then game variety is improved, but device complexity and cost increase

Engineering Contradiction:

Improvegame varietyVSAvoidreel configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by enabling a single set of mechanical reels to serve multiple game variations through dynamic paytable selection. The system stores multiple paytables in memory, each corresponding to different game rules and symbol combinations, allowing the same physical reels to be configured for different games by simply loading different paytables, thus eliminating the need for separate reels for each game variant.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements dynamics by making the paytable selection process changeable and adaptable. The system can dynamically switch between different paytables based on game mode selections, player preferences, or random determinations. This dynamic reconfiguration allows the reels to adapt their behavior and payout structures without physical modification, resolving the contradiction between game variety and device complexity.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple mechanical reels are provided for different games, then game variety is improved, but manufacturing cost increases

Engineering Contradiction:

Improvegame varietyVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies universality by enabling a single set of mechanical reels to serve multiple game variations through dynamic paytable selection. The system stores multiple paytables in memory, each corresponding to different game rules and symbol combinations, allowing the same physical reels to be configured for different games by simply loading different paytables, thus eliminating the need for separate reels for each game variant.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses copying by creating virtual representations of different games through software-based paytables rather than physical copies of reels. Each paytable acts as a digital template that defines the game's symbol combinations, probabilities, and payout structures, allowing infinite game variations to be generated from a single physical reel set without additional manufacturing costs.

Inventive Principle:

Principle #26Copying

3Device complexity

If static mechanical reels are used, then device simplicity is maintained, but player influence over game dynamics is reduced

Engineering Contradiction:

Improvereel structureVSAvoidplayer influence

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamics by making the paytable selection process changeable and adaptable. The system can dynamically switch between different paytables based on game mode selections, player preferences, or random determinations. This dynamic reconfiguration allows the reels to adapt their behavior and payout structures without physical modification, resolving the contradiction between game variety and device complexity.
