Solution Overview

Problem

Conventional RFID tags used for service purchases lack the provision of content information and authentication, leading to increased communication time and uncertainty for users when purchasing digital content.

Innovation Solution

An RFID tag system that includes a method for acquiring and authenticating service purchase information, using an RFID tag and reader to validate and process payments for digital content purchases, thereby ensuring reliable and efficient service transactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If conventional RFID tag provides only demo content information without purchase information, then the RFID tag structure remains simple, but communication time increases due to separate server access for purchase

Engineering Contradiction:

Improvecommunication timeVSAvoidRFID tag structure

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent combines purchase information, content information, and right information into a single RFID tag structure. The tag now stores comprehensive data including content identification, purchase status, and authentication information, eliminating the need for separate server access and reducing communication time.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The RFID tag pre-stores purchase information and authentication data before the actual purchase transaction. This preliminary preparation allows the system to validate purchases quickly without requiring real-time server communication for basic authentication, thereby reducing communication time.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If conventional RFID tag does not provide authentication function, then the RFID tag remains simple, but reliability of purchase information is compromised

Engineering Contradiction:

Improveauthentication functionVSAvoidRFID tag structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates authentication functionality directly into the RFID tag by storing right information and purchase authentication data within the tag itself. This merging of authentication capabilities with the tag structure ensures reliable verification of purchase information while maintaining a unified, manageable system.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If user must determine purchase decision shortly after obtaining demo content information, then the system responds quickly, but user convenience is reduced due to time pressure

Engineering Contradiction:

Improveuser convenienceVSAvoidpurchase processing speed

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The RFID tag pre-stores all necessary purchase information including content details, pricing, and authentication data. This allows users to review complete purchase information at their own pace without time pressure, while the system maintains readiness for immediate transaction processing when the user confirms.

Inventive Principle:

Principle #10Preliminary action
