Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current transaction systems, including credit cards, debit cards, and SmartCards, require physical contact and are cumbersome, especially at point-of-sale (PoS) and automated teller machine (ATM) centers, lacking secure and efficient biometric authentication, and often necessitate multiple devices for different banks, with inadequate secondary authentication methods.

Innovation Solution

A smart wearable ring with embedded RFID/NFC for contactless transactions, incorporating a fingerprint sensor and presence sensor for biometric authentication, directly connected to a bank server for secure and seamless transactions across multiple banks without the need for frequent loading of funds, utilizing a unique ring ID and PIN for authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If physical cards (credit/debit/SmartCards) are used for transactions, then transaction capability is provided, but physical contact and manual operation are required making the process cumbersome

Engineering Contradiction:

Improvetransaction processVSAvoidphysical card system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces mechanical card-swiping systems with a wireless communication system using electromagnetic fields. The wearable device communicates transaction data wirelessly to the PoS terminal through RFID/NFC technology, eliminating the need for physical card insertion or swiping actions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables automatic authentication and transaction processing without manual intervention. The wearable device automatically transmits user identification and transaction data when brought near the PoS terminal, and the system automatically verifies credentials and completes transactions without requiring users to manually enter information.

Inventive Principle:

Principle #25Self-service

2Reliability

If traditional authentication methods (PIN entry) are used, then security is provided, but multiple devices and frequent fund loading are required

Engineering Contradiction:

Improveauthentication securityVSAvoidauthentication system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple authentication mechanisms into a single integrated wearable device. The device merges biometric authentication (fingerprint sensor), wireless communication (RFID/NFC), and fund management capabilities into one compact unit, replacing the need for separate cards, PIN pads, and fund loading procedures.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The wearable device serves multiple functions: it acts as an identification card, authentication device, fund storage medium, and transaction terminal interface. The device can be used across different banks and transaction types without requiring separate devices or frequent reconfiguration.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If biometric authentication is implemented, then security is enhanced, but physical contact with the system is still required

Engineering Contradiction:

Improveuser identificationVSAvoidauthentication process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical fingerprint scanning systems with an integrated on-device fingerprint sensor. Instead of requiring users to place their finger on a separate PoS terminal scanner, the wearable device contains its own fingerprint sensor that captures and verifies biometric data locally, then transmits only the verification result wirelessly.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
