Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems for enabling transactions, such as fueling, for vehicles using tokens within a blockchain network face challenges when the transaction needs to occur at a location physically remote from the vehicle, as there is no direct method for the vehicle to communicate the token to a point of sale system.

Innovation Solution

Transferring the token from the vehicle to a mobile device, which can then communicate it to a point of sale system, allowing the mobile device holder to complete the transaction, even if the vehicle is not physically present, through various communication protocols like NFC, Wi-Fi, or Bluetooth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the vehicle directly communicates the token to the point of sale system, then the transaction can be completed efficiently at the vehicle location, but the system cannot support transactions at physically remote locations

Engineering Contradiction:

Improvetransaction location flexibilityVSAvoidcommunication system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a mobile device as an intermediary carrier to transfer the token from the vehicle to the point of sale system. The token is first transferred to the mobile device, which then communicates it to the POS system, enabling remote transactions without requiring direct vehicle-POS communication infrastructure.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the token is transferred to a mobile device for remote transaction completion, then transactions can occur at any location, but the risk of token misuse and unauthorized transactions increases

Engineering Contradiction:

Improvetransaction location flexibilityVSAvoidtransaction security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary verification of transaction conditions before the token is transferred and used. The processor verifies geographical location, timing, and other specified conditions in advance, and only then allows the token to be transferred to the mobile device and used for transaction completion.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors and verifies transaction conditions during the process. The processor receives information about geographical location, timing, and other conditions, and uses this feedback to determine whether to allow or deny token transfer and transaction completion.

Inventive Principle:

Principle #23Feedback

AI summary

A method of communicating a token to a mobile device includes a server or computing device issuing a token, the token defining a bond for a transaction associated with a vehicle and associated with an entity. The method also includes transferring the token to a mobile device. The token can then be communicated from the mobile device to a point of sale (POS) device to enable completion of the transaction associated with the vehicle.
