Solution Overview

Problem

Existing wagering games lack options for player interaction and customization, particularly in the form of physical tokens, which are used to enhance player engagement and enjoyment.

Innovation Solution

Physical cryptographic tokens are used to enhance player interaction and enjoyment, which include a passive identifier device for token authentication and a token dispenser device for managing cryptographic tokens.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If physical cryptographic tokens are introduced to enhance player interaction and enjoyment, then player engagement is improved, but device complexity increases due to the need for passive identifier devices and token management systems

Engineering Contradiction:
Improveplayer interaction optionsVSAvoidtoken management system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system is divided into separate functional components: physical tokens with embedded passive identifier devices, token dispenser devices for distribution, and cryptographic token management devices for tracking. This segmentation allows each component to perform its specific function independently, reducing overall system complexity while enabling enhanced player interaction through tangible physical tokens.

Inventive Principle:
Principle #1Segmentation

2Reliability

If passive identifier devices are embedded in physical tokens for authentication, then security is enhanced, but manufacturing complexity increases

Engineering Contradiction:
Improvetoken authentication securityVSAvoidphysical token manufacturing
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The passive identifier devices embedded in the physical tokens enable self-service authentication without requiring active power sources or complex programming in the tokens themselves. The tokens automatically provide authentication data when queried by authorized devices, simplifying the manufacturing process while maintaining high security standards through cryptographic verification.

Inventive Principle:
Principle #25Self-service

AI summary

A physical cryptographic token may include a substrate and a passive identifier device for passively providing a token identifier associated with the cryptographic token to a token authentication device. A cryptographic token management device may include a token authentication device for receiving token identifier from a passive identifier device of a physical cryptographic token, a token management interface for managing cryptographic tokens associated with token identifiers of physical cryptographic tokens, and a token dispenser device for dispensing a physical cryptographic token associated with a token identifier.
