Solution Overview

Problem

Mobile terminals without electronic money functions cannot perform electronic money transactions, and even those with the function are limited to specific specifications, preventing cross-country transactions.

Innovation Solution

A mobile router equipped with dual wireless communication units (NFC and wireless LAN) registers allowed mobile terminals and confirms their presence before enabling electronic money transactions through NFC communication for international compatibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a mobile terminal uses a specific electronic money specification, then electronic money transaction is enabled for that specification, but electronic money transaction with different specifications is prevented

Engineering Contradiction:
Improveelectronic money transaction compatibilityVSAvoidtransaction security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a mobile router as an intermediary device between the mobile terminal and the external environment. The mobile router possesses electronic money function and acts as a mediator that enables electronic money transactions for mobile terminals without native electronic money capability. The router confirms the presence of the mobile terminal through wireless LAN communication before executing electronic money transactions via NFC communication, thus providing adaptability while maintaining security through the intermediary's control mechanisms

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the mobile router confirms terminal presence before transaction, then transaction security is improved, but transaction processing time is increased

Engineering Contradiction:
Improvetransaction securityVSAvoidtransaction processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by having the mobile router confirm the presence of the mobile terminal through wireless LAN communication before the actual electronic money transaction occurs. This preliminary confirmation step ensures that only authorized terminals can initiate transactions, enhancing security. The confirmation process happens in advance, allowing the subsequent transaction to proceed efficiently once authorization is established

Inventive Principle:
Principle #10Preliminary action
