Solution Overview

Problem

Security assets, such as stocks and bonds, are not commonly used for everyday payments due to longer transaction times, fluctuating values, and high transaction costs, making them unsuitable for merchants and impractical for fractional transactions.

Innovation Solution

A payment service system that allows users to manage and transfer security assets in fractions, using ledgers to record ownership and facilitate transactions, reducing costs and improving efficiency by enabling purchases, sales, and payments with arbitrarily specified quantities of security assets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If security assets are used for everyday payments, then investment diversification is improved, but transaction time increases

Engineering Contradiction:
Improveinvestment diversificationVSAvoidtransaction time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent segments security assets into fractional units, allowing payments to be made in partial shares rather than whole units. This segmentation enables faster transaction processing while maintaining investment diversification benefits, as users can transfer smaller portions of security assets without waiting for full unit consolidation or approval processes.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If security assets are accepted by merchants, then payment options are improved, but transaction costs increase

Engineering Contradiction:
Improvepayment optionsVSAvoidtransaction costs
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent introduces a payment network as an intermediary layer between security asset holders and merchants. This intermediary handles the conversion and settlement processes, reducing direct transaction costs for merchants while expanding payment options. The network mediates the complex interactions between different security assets and merchant requirements, making the system more efficient and cost-effective.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If fractional transactions of security assets are enabled, then payment flexibility is improved, but system complexity increases

Engineering Contradiction:
Improvepayment flexibilityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent creates digital representations or copies of security asset ownership rights that can be divided and transferred fractionally. Instead of physically dividing actual securities, the system uses digital tokens or records that replicate ownership rights, enabling flexible fractional transactions while keeping the underlying asset structure simple and manageable.

Inventive Principle:
Principle #26Copying

4Productivity

If security assets are used for payments, then asset utilization is improved, but reliability decreases due to value fluctuation

Engineering Contradiction:
Improveasset utilizationVSAvoidvalue stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic parameter adjustment mechanisms that monitor security asset values and automatically adjust transaction parameters such as settlement timing, conversion rates, or collateral requirements. When value fluctuation exceeds certain thresholds, the system modifies transaction parameters to maintain reliability, allowing continuous asset utilization while protecting against excessive value instability.

Inventive Principle:
Principle #35Parameter changes

AI summary

In one embodiment, a method includes receiving a request for payment associated with a transaction between a merchant and a customer, where a payment amount is specified in a fiat currency, determining a preference of the customer to pay for the transaction using a security asset, and verifying that a value of the security asset held by the payment system and assigned to the customer is sufficient to satisfy the payment amount. The method also includes initiating a transfer of at least a portion of the value of the security asset from a customer balance of the customer to a service balance of the payment service, initiating a transfer of a value in the fiat currency from the service balance of the payment service to a merchant balance of the merchant, and storing a record of the transaction between the customer and the merchant.
