Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Consumers are hesitant to purchase items with embedded RFID security tags due to privacy concerns, as existing methods to deactivate or reduce the RFID's functionality do not allow for continued use in downstream applications like returns management and recycling, and consumers lack means to detect the RFID's status or control its functionality.

Innovation Solution

A system that integrates a bar code with an RFID chip, allowing consumers to query, identify, and change the mode of the RFID chip via a management platform, providing status indication and enabling control over its functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If RFID chip functionality is deactivated to protect consumer privacy, then consumer privacy is improved, but the ability to use RFID for downstream applications like returns management and recycling is lost

Engineering Contradiction:

Improveconsumer privacy concernVSAvoiddownstream application usability

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The RFID chip is configured to dynamically change its operational state based on external commands. It can switch between active, deactivated, and restricted communication modes, allowing it to adapt to different situations - protecting privacy when needed while maintaining functionality for authorized downstream applications.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The RFID chip's communication parameters are made changeable through commands received via bar code scanning. The chip can alter its operational mode (active/deactivated/restricted) and communication characteristics based on these commands, enabling flexible control over privacy and functionality trade-offs.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If RFID chip remains active for downstream applications, then downstream application usability is maintained, but consumer privacy is compromised due to continuous communication capability

Engineering Contradiction:

Improvedownstream application usabilityVSAvoidconsumer privacy concern

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system transitions from a static RFID chip state to a dynamic one where the chip can change its communication behavior based on received commands. This allows the chip to be active when needed for applications while becoming deactivated or restricted for privacy protection.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The consumer gains direct control over the RFID chip's operational state through bar code scanning and command transmission. The chip responds to these commands by adjusting its own communication behavior, enabling consumer-directed privacy management without requiring retailer intervention.

Inventive Principle:

Principle #25Self-service

3Object-affected harmful factors

If existing deactivation methods are used, then consumer privacy is improved, but the RFID functionality for inventory management and recycling is lost

Engineering Contradiction:

Improveconsumer privacy concernVSAvoidinventory management functionality

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

Instead of permanent deactivation, the system uses dynamic state changes. The RFID chip can be deactivated temporarily or restricted to specific communication modes, allowing inventory management and recycling functions to continue when needed while protecting privacy at other times.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of the RFID chip rather than completely deactivating it. By adjusting communication modes and restrictions, the chip can maintain necessary functionality for inventory and recycling while reducing communication capabilities to protect consumer privacy.

Inventive Principle:

Principle #35Parameter changes

4Object-affected harmful factors

If consumers want to control RFID functionality, then consumer privacy is improved, but the complexity of the system increases due to additional control mechanisms

Engineering Contradiction:

Improveconsumer privacy concernVSAvoidsystem complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The bar code serves as an intermediary that carries commands to control the RFID chip. Instead of requiring direct complex interaction with the RFID chip, consumers can use standard bar code scanning devices to transmit control commands, simplifying the user interface while maintaining control capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The bar code system serves multiple functions - it can provide product information, enable consumer control of RFID functionality, and facilitate communication with the management platform. This multi-functionality reduces the need for separate control mechanisms, thereby limiting the increase in system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A bar code may be integrated with a product, and a management platform may be configured to: receive a query for the mode information of the RFID chip via the bar code, identify the RFID chip based on the bar code; and transmit an indication of a mode of the RFID chip. The bar code may include a two-dimensional code, a quick response (QR code), a three-dimensional code, and/or any graphical or visual machine-readable code.
