Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If currency conversion is used to enable international transactions, then participants can trade across different monetary systems, but exchange rate fluctuations and currency devaluation create economic risk and uncertainty

Engineering Contradiction:

Improveability to conduct international transactionsVSAvoideconomic risk from exchange rate fluctuations

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by allowing participants to lock in exchange rates at the time of transaction initiation. The system determines and fixes the exchange rate before the transaction is completed, protecting participants from future currency fluctuations. This is achieved through the transaction facility that automatically calculates and locks exchange rates when a transaction is initiated, eliminating the risk of rate changes during processing.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If credit card companies settle transactions at their discretion, then they can minimize their own risk, but buyers bear the risk of currency devaluation before settlement

Engineering Contradiction:

Improvecredit card company risk managementVSAvoidbuyer uncertainty and inconvenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent reverses the conventional approach by applying preliminary action to benefit the buyer rather than the credit card company. The system locks in the exchange rate at transaction initiation, determining the settlement amount before the transaction is completed. This eliminates buyer uncertainty about the final amount while still allowing the credit card company to settle at favorable rates.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The transaction facility acts as an intermediary between the buyer and credit card company, managing the exchange rate risk. The system automatically determines exchange rates and locks them in, serving as a mediator that protects both parties from currency fluctuations while enabling the credit card company to maintain flexible settlement timing.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If sellers accept foreign currency directly, then they can sell products internationally, but they incur risk due to possible changes in currency exchange rates

Engineering Contradiction:

Improveability to sell in multiple currenciesVSAvoidseller risk from exchange rate changes

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by locking in exchange rates at the time of transaction initiation. Sellers accept foreign currency payments with the exchange rate determined and fixed beforehand, protecting them from future currency fluctuations. The system automatically calculates the settled amount based on the locked rate, eliminating seller risk while maintaining the ability to accept multiple currencies.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If buyers convert currency before purchase, then they can buy products from sellers accepting specific currencies, but they assume risk of devaluation and possible non-convertibility

Engineering Contradiction:

Improveability to purchase from any sellerVSAvoidbuyer risk of devaluation and non-convertibility

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent eliminates the need for preliminary currency conversion by locking in exchange rates within the transaction facility. Buyers can purchase from any seller accepting the facility's services without converting currency beforehand, as the system determines and locks the exchange rate at transaction initiation. This removes the risk of devaluation and non-convertibility while maintaining global purchasing ability.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method and apparatus for facilitating online payment transactions in multiple currencies between participants of a network-based transaction facility are described. In one embodiment, a user interface is communicated to a sender via a communications network. The user interface facilitates sender input with respect to a desired currency in which a payment to a recipient is to be made. Further, data identifying a sender-selected currency is received from the sender via the communications network. In response, information identifying a current exchange rate for conversion between the sender-selected currency and a sender primary currency is communicated to the sender via the communications network. If the sender confirms the payment in the sender-selected currency, the recipient is informed about the payment in the sender-selected currency.
