Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a persistent non-symbol element is introduced to enhance gameplay engagement, then player interest and retention are improved, but device complexity increases

Engineering Contradiction:
Improvegameplay engagementVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The non-symbol element dynamically changes position across reels based on game outcomes. The element moves from one reel to another according to symbol combinations, transforming a static game element into a dynamic one that adapts to gameplay conditions, thereby enhancing engagement without requiring complex external systems

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The non-symbol element serves multiple functions: it acts as a game mechanic that moves across reels, triggers bonuses when landing on specific symbols, and influences subsequent gameplay. This multi-functionality reduces the need for separate systems, maintaining simplicity while enhancing versatility

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

2Adaptability or versatility

If a persistent non-symbol element moves across reels affecting each play, then game dynamics are enhanced, but measurement precision requirements increase

Engineering Contradiction:
Improvegame dynamicsVSAvoidposition tracking accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system uses visual representations and symbolic markers to track the non-symbol element's position rather than requiring precise physical measurement. The element's position is indicated through display graphics and game state data, eliminating the need for high-precision measurement mechanisms while maintaining accurate game dynamics

Inventive Principle:
Principle #26Copying

AI summary

An electronic gaming machine (“EGM”) can display a grid of symbols as part of a slot game. The EGM can further detect a triggering event as part of the slot game. The EGM can further, responsive to detecting the triggering event, determine that a non-symbol element is at a position relative to the grid of symbols. The EGM can further display the non-symbol element at the position.
