Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems lack efficient methods for managing and transferring digital promotions, such as coupons, across blockchain networks while ensuring compliance with acceptance rules, leading to potential misuse and lack of transparency in ownership and redemption.

Innovation Solution

A non-fungible token (NFT) system that includes immutable and mutable attributes to represent digital promotions, allowing for secure transfer and redemption by setting acceptance rules, with the immutable attribute referencing the rules and the mutable attribute indicating acceptance, enabling secure transfer between shopper devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If digital promotions are transferred across blockchain networks without immutable rule references, then transfer flexibility is improved, but compliance verification and rule adherence deteriorate

Engineering Contradiction:

Improvetransfer flexibilityVSAvoidcompliance verification

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces an intermediary structure (immutable attribute containing rule set reference) that mediates between the digital promotion and its acceptance rules. This intermediary enables flexible transfer of the promotion while maintaining reliable compliance verification, as the immutable reference ensures rules are consistently applied across blockchain networks without restricting transferability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the digital promotion representation into distinct components: an immutable attribute containing the rule set reference and a mutable attribute for acceptance status. This segmentation allows the promotion to be transferred flexibly while maintaining separate, verifiable rule compliance, resolving the contradiction between transferability and compliance verification.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If digital promotions use only mutable attributes for rule acceptance, then ease of updating acceptance status is improved, but transparency and trust in rule adherence deteriorate

Engineering Contradiction:

Improveupdating acceptance statusVSAvoidtransparency

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent divides the attribute structure into immutable and mutable components. The immutable attribute permanently stores the rule set reference, ensuring transparency and trust, while the mutable attribute efficiently tracks acceptance status updates. This segmentation maintains both transparency and operational ease simultaneously.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary action by establishing the immutable rule reference before any acceptance operations occur. This preliminary setup ensures transparency is built into the system from the start, while subsequent mutable updates to acceptance status remain efficient and traceable, preventing information loss.

Inventive Principle:

Principle #10Preliminary action

3Speed

If digital promotions are transferred without immutable rule references, then transfer speed is improved, but rule compliance verification and prevention of misuse deteriorate

Engineering Contradiction:

Improvetransfer speedVSAvoidmisuse risk

Core Design Contradiction:

SpeedVSObject-affected harmful factors

Solution Approach 1:

The immutable attribute serves as a lightweight intermediary that enables rapid transfer verification through cryptographic references to rule sets, without requiring heavy data transmission. This maintains high transfer speed while preventing misuse through enforceable, verifiable rule compliance embedded in the token structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Reliability

If digital promotions include comprehensive acceptance rules, then compliance and security are improved, but system complexity and difficulty of operation worsen

Engineering Contradiction:

ImprovecomplianceVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex rule set details from the transfer process itself, storing only an immutable reference to the rule set in the token attribute. This extraction maintains comprehensive compliance verification while reducing system complexity during transfer operations, as the detailed rules are managed separately rather than embedded in each transaction.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

An NFT processing server may cooperate with a first device to communicate a notification of a digital promotion having an acceptance rule set associated therewith. A tethered non-fungible token (tNFT) representative of the promotion may be generated and stored on a blockchain network. The tNFT may have an immutable attribute including a reference to the rule set, and a mutable attribute indicative of rule set acceptance. A first shopper may be prompted for rule set acceptance, and, thereupon, the server may set the mutable attribute to be indicative of the acceptance, permit transfer of the digital promotion to a second device, and transfer the promotion on the blockchain network to the second device by transferring the tNFT to a digital wallet. The server may also prompt a second shopper for acceptance of the rule set, and thereupon, set the mutable attribute to be indicative of the acceptance.
