Innovation Solution

A personal data protection system that includes a device capable of detecting carrier signals from RFID readers and activating a blocking mechanism to prevent reading of RFID chips, integrated with holders that transmit alert signals when the device is removed, ensuring the RFID chip remains secure within a protected range.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If RFID-enabled devices are made contactless for convenience, then ease of operation is improved, but vulnerability to unauthorized data access increases

Engineering Contradiction:

Improvecontactless operation convenienceVSAvoidunauthorized data access

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary anti-action by implementing alert mechanisms that detect and warn of unauthorized RFID readers before data can be compromised. The system proactively monitors for carrier signals from unauthorized readers and triggers visual or audible alerts to notify the user, preventing unauthorized data access before it occurs.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The patent introduces an intermediary monitoring system that sits between the RFID chip and unauthorized readers. This intermediary layer detects carrier signals from unauthorized readers and generates alert signals, creating a protective buffer that warns users of potential threats while allowing legitimate contactless operations to proceed.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If RFID chips store comprehensive personal data for functionality, then device capability is improved, but risk of identity theft increases

Engineering Contradiction:

Improvedata storage capabilityVSAvoididentity theft risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements feedback mechanisms that continuously monitor RFID transactions and alert users to unauthorized access attempts. The system provides real-time feedback about the status of RFID operations, notifying users when unauthorized readers are detected, thereby enabling them to take protective action while maintaining full data storage capability for legitimate uses.

Inventive Principle:

Principle #23Feedback

3Device complexity

If no shielding mechanism is implemented for RFID devices, then device complexity is reduced, but data security against carrier signals deteriorates

Engineering Contradiction:

Improvesystem structure simplicityVSAvoidcarrier signal interference

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces physical shielding mechanisms with electronic detection and alert systems. Instead of using metal barriers or electromagnetic shielding materials to block carrier signals, the system uses electronic sensors to detect the presence of unauthorized readers and generates electronic alert signals, achieving protection through information rather than physical obstruction.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
