Solution Overview

Problem

Existing gaming systems lack dynamic and engaging mechanisms for accumulating and collecting symbols, limiting player interaction and reward diversity.

Innovation Solution

A gaming system that temporarily accumulates collectable symbols based on the occurrence of a symbol collection event, using collector symbols to differentiate and redeem accumulated symbols, allowing multiple paths to awards through individual or multiple game plays, and supporting various game types and platforms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If symbols are accumulated indefinitely in existing gaming systems, then the system structure becomes complex and management becomes difficult, but player engagement and reward diversity remain limited

Engineering Contradiction:
Improvereward diversityVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic symbol accumulation with automatic expiration based on play counts or time periods. Symbols are not statically stored indefinitely but dynamically managed with set durations, automatically expiring after a predetermined number of plays or time period. This dynamic approach enables diverse reward paths while maintaining manageable system complexity through automated lifecycle management.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system pre-establishes collection criteria and expiration conditions before symbols are accumulated. Predetermined play count thresholds and time periods are set in advance, allowing the system to manage symbol accumulation with pre-defined rules rather than complex real-time decision structures. This preliminary configuration enables versatility while controlling complexity.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple collection criteria are implemented to provide diverse award paths, then player engagement increases, but the difficulty of detecting and measuring collection events increases

Engineering Contradiction:
Improveaward realization pathsVSAvoidcollection event tracking
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The system implements automated feedback mechanisms that track symbol accumulations and automatically detect when collection criteria are met. The gaming system monitors play counts and time periods, providing continuous feedback on accumulation status. When symbols reach predetermined thresholds or time periods expire, the system automatically triggers collection events, eliminating manual tracking complexity while enabling multiple award paths.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The accumulation and collection system operates autonomously using self-service mechanisms. Symbols automatically accumulate during gameplay, and the system self-monitors collection criteria without requiring external intervention. The predetermined play count thresholds and time periods enable the system to self-determine when collection events should occur, reducing measurement difficulty while maintaining versatile award paths.

Inventive Principle:
Principle #25Self-service

3Quantity of substance

If symbols are accumulated for extended periods, then more awards can be redeemed, but the reliability of symbol retention decreases due to potential expiration

Engineering Contradiction:
Improvenumber of redeemable awardsVSAvoidsymbol retention
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The system implements periodic action through predetermined time periods and play count intervals. Symbols are accumulated for specific durations or until a set number of plays occur, creating regular cycles of accumulation and potential redemption. This periodic structure allows multiple awards to be redeemed over time while maintaining reliable tracking through automated expiration based on pre-set intervals, balancing quantity with retention reliability.

Inventive Principle:
Principle #19Periodic action
