Solution Overview

Problem

Electronic gaming machines (EGMs) consume significant amounts of energy and generate excessive heat, leading to increased operational costs and environmental concerns, particularly in large casino environments.

Innovation Solution

Implementing a system with multiple display interfaces, including integrated and removable GPUs, and a Slot Machine Interface Board (SMIB), which allows for dynamic switching of graphical content to reduce power consumption by activating and deactivating display interfaces based on trigger conditions such as activity levels and player presence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a single high-performance display interface is used to maintain high graphical output quality, then graphical content quality is improved, but power consumption increases

Engineering Contradiction:

Improvegraphical content qualityVSAvoidpower consumption

Core Design Contradiction:

Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The system divides the display interface into multiple independent interfaces (first display interface and second display interface), each capable of operating independently. The processor can selectively activate only the necessary interface based on trigger conditions, thereby maintaining graphical quality when needed while reducing power consumption during idle periods.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically switches between different display interfaces based on real-time trigger conditions (e.g., player presence, game state). The first display interface may be used during active gameplay while the second interface handles idle or low-power states, allowing the system to adapt its power consumption profile to actual operational needs.

Inventive Principle:

Principle #15Dynamics

2Reliability

If multiple display interfaces are maintained active for seamless switching, then system reliability is improved, but power consumption increases

Engineering Contradiction:

Improveseamless gameplay continuityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system prepares multiple display interfaces in advance, with the second interface potentially pre-loaded or pre-configured to enable rapid switching. This preliminary preparation ensures that when a switch is needed (based on trigger conditions), the transition is seamless and maintains gameplay continuity without interruption.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Different display interfaces are assigned different operational qualities based on their current usage state. The first interface may operate at full performance during active gameplay, while the second interface operates at reduced performance or in standby mode during idle periods, optimizing the balance between reliability and power consumption.

Inventive Principle:

Principle #3Local quality

3Illumination intensity

If high-performance graphical processing is continuously provided, then graphical content quality is improved, but heat generation increases

Engineering Contradiction:

Improvegraphical content qualityVSAvoidheat generation

Core Design Contradiction:

Illumination intensityVSTemperature

Solution Approach 1:

The system employs periodic switching between display interfaces based on trigger conditions related to gameplay activity. During active gameplay periods, the first interface provides high-performance graphical output. During idle or transition periods, the system switches to the second interface or reduces graphical processing, thereby periodically reducing heat generation while maintaining quality when needed.

Inventive Principle:

Principle #19Periodic action

AI summary

A gaming device includes a display device, a processor circuit, a first gaming device display interface coupled between the processor circuit and the display device, a second gaming device display interface coupled between the processor circuit and the display device in parallel with the first gaming device display interface, and a memory coupled to the processor circuit. First graphical content is provided to the display device via the first gaming device display interface. In response to a determination that a first trigger condition indicative of a power consumption reduction state for the gaming device has been satisfied, second graphical content is provided to the display device via the second gaming device display interface, and provision of the first graphical content to the display device via the first gaming device display interface is discontinued.
