Solution Overview

Problem

Virtual items in video games and virtual reality environments are at risk of loss due to hacking, computer failures, or platform discontinuation, lacking real-world security and accessibility.

Innovation Solution

A 3D printing system and method that transforms limited edition virtual objects into tangible physical items, using digital rights management to prevent duplication, associating them with non-fungible tokens, and incorporating QR codes for ownership verification, while ensuring each item is printable only once.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If virtual items are stored only in digital form in virtual environments, then users can access and display them within the game platform, but they are vulnerable to loss from hacking, computer failures, or platform discontinuation

Engineering Contradiction:

Improvesecurity of virtual itemsVSAvoidrisk of loss from hacking or storage failure

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a 3D printing system as an intermediary between the virtual digital environment and the physical real world. The system converts virtual item data into physical 3D printed objects, creating a tangible backup that exists independently of digital storage systems. This intermediary transformation process allows users to preserve virtual achievements in a secure physical form that cannot be hacked or lost to digital storage failures.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If 3D printer files are made available for virtual items, then users can create physical copies of their achievements, but duplication of files may compromise the uniqueness and scarcity of limited edition items

Engineering Contradiction:

Improveability to print physical itemsVSAvoiduniqueness of limited edition items

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent implements preliminary actions by embedding digital rights management (DRM) protection and uniqueness identifiers into the 3D printer files before they are distributed to users. The system pre-configures files with authentication mechanisms and scarcity metadata that prevent unauthorized duplication. This preliminary protection ensures that when users print physical items, the uniqueness and limited edition status are maintained through built-in technical constraints.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical copying methods with digital authentication and blockchain-based verification systems. Instead of relying on physical security measures to prevent duplication, the system uses cryptographic verification, NFT association, and server-side validation to control file distribution and verify authenticity. This substitution of mechanical security with digital verification mechanisms enables precise control over file duplication while maintaining ease of legitimate printing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If digital rights management is implemented to prevent duplication, then authenticity and scarcity are maintained, but system complexity increases

Engineering Contradiction:

Improveauthenticity verificationVSAvoidcomplexity of DRM system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service mechanisms where the 3D printed physical objects contain embedded verification elements (such as QR codes, NFC tags, or unique identifiers) that enable automatic authentication. When users or collectors verify an item, the system automatically checks the embedded identifier against the blockchain or server database to confirm authenticity and ownership. This self-verifying approach reduces the need for complex manual verification processes and simplifies the user experience while maintaining strong authentication capabilities.

Inventive Principle:

Principle #25Self-service

AI summary

A 3D printing system and method for limited edition virtual objects is disclosed. The method including: enabling a user to obtain a limited edition virtual object associated with an activity of the user in a virtual environment; receiving a request from the user to 3D print the limited edition virtual object; preparing a 3D printer file of the limited edition virtual object requested by the user; sending the 3D printer file of the limited edition virtual object to a 3D printer to be printed; and validating authenticity of transformation of the limited edition virtual object into a 3D printed tangible physical item.
