Solution Overview

Problem

Conventional slot machines offer limited gameplay variety, leading to player boredom and a need for enhanced gaming experiences to attract more players.

Innovation Solution

A slot machine gaming device featuring multiple symbols at a single symbol position, including activator symbols that trigger bonus rounds and replicator symbols, which replace original symbols to create winning combinations and provide additional awards, such as free spins with a locked wild symbol during the bonus round.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional slot machine gameplay is used, then the device structure remains simple and easy to manufacture, but player engagement and excitement are limited leading to boredom

Engineering Contradiction:
Improvegameplay varietyVSAvoidgame structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic symbol transformation where symbols can change from single symbols to multiple symbols (e.g., 1x to 2x, 2x to 3x) during gameplay. This dynamic transformation allows the game structure to adapt and evolve during play, providing variety without requiring entirely separate game mechanisms. The symbols dynamically adjust their multiplicity based on game events, maintaining engagement while using a unified game framework.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs nested game structures where bonus rounds are embedded within the base game, and additional features like locked wild symbols and replicator symbols are nested within the bonus round structure. This nesting allows multiple layers of gameplay complexity to coexist within a single unified device, providing varied experiences without requiring separate physical machines for each game mode.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Productivity

If multiple symbols at single position and replicator symbols are implemented, then additional winning opportunities and player excitement are provided, but the device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improvewinning opportunitiesVSAvoiddevice construction
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The patent uses replicator symbols that function as copying mechanisms, where a single symbol can replicate to create multiple instances of itself during gameplay. This virtual copying through software logic provides additional winning opportunities without requiring physical multiplication of symbol components. The replicator symbol creates virtual copies that appear on the reels during bonus rounds, increasing productivity through digital rather than physical means.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent implements multi-functional symbols that can serve different purposes depending on game context. For example, wild symbols can function as both regular symbols and locked wilds during bonus rounds, and symbols can transition between single and multiple symbol states. This universality allows a limited set of physical components to perform multiple functions, reducing manufacturing complexity while maintaining high winning opportunity potential.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If activator symbols triggering bonus rounds are added, then player engagement increases, but the game structure becomes more complex

Engineering Contradiction:
Improvebonus round activationVSAvoidgame mechanics
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary action through activator symbols that are positioned in advance on the reels and trigger bonus rounds when specific combinations appear. This preliminary setup of trigger conditions allows the game to transition smoothly into bonus modes without requiring complex real-time decision-making mechanisms. The activator symbols are pre-configured on the reel strips, simplifying the triggering logic while maintaining engagement.

Inventive Principle:
Principle #10Preliminary action
