Solution Overview

Problem

Current gaming devices and Electronic Gaming Machines (EGMs) managed in large computational networks face challenges such as network downtime, operational costs, and maintenance, which are exacerbated by offering monetary rewards to players.

Innovation Solution

A gaming system that facilitates the acquisition and stacking of Non-Fungible Tokens (NFTs), allowing players to redeem earned NFTs, stack them with existing NFTs in their digital wallet, and combine them into higher-tier NFTs, providing new gameplay features and rewards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If monetary rewards are offered to players of gaming devices and EGMs, then player motivation is improved, but operational costs and network complexity increase

Engineering Contradiction:
Improveplayer motivationVSAvoidnetwork complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses NFTs as digital copies or representations of game assets, rewards, and collectibles that can be traded and stacked without requiring physical delivery or complex monetary transactions. This reduces operational costs while maintaining player engagement through virtual asset accumulation.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If multiple low-value NFTs are distributed to players, then player engagement is improved, but marketplace flooding occurs

Engineering Contradiction:
Improveplayer engagementVSAvoidmarketplace flooding
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent implements a stacking mechanism where multiple identical or complementary NFTs can be combined to create a single higher-tier NFT with enhanced value and attributes. This consolidates multiple low-value tokens into fewer high-value tokens, reducing marketplace flooding while maintaining player engagement through progressive collection and combination goals.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If players accumulate multiple NFTs in their digital wallet, then collection value is improved, but wallet management complexity increases

Engineering Contradiction:
Improvecollection valueVSAvoidwallet management
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The stacking feature automatically combines identical NFTs held by players, reducing the number of individual tokens they need to manage. Instead of tracking dozens of separate low-tier NFTs, players see consolidated representations that reflect their total collection value and potential for further stacking, significantly simplifying wallet management while preserving collection value.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of operation

If NFT stacking is enabled to consolidate low-value NFTs, then wallet management is simplified, but loss of individual NFT value occurs

Engineering Contradiction:
Improvewallet managementVSAvoidindividual NFT value
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The stacking mechanism transforms the value parameters of NFTs by combining multiple units into a higher-tier configuration. Rather than losing value, players gain access to new attributes, rarity levels, and functionality associated with stacked NFTs. The system recalculates value based on the combined properties, ensuring that the total value increases or is maintained while simplifying management.

Inventive Principle:
Principle #35Parameter changes
