Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current RFID tag applications lack user control over data activation and management, leading to untimely or unauthorized interrogation, which hampers efficient inventory and supply chain management.

Innovation Solution

A user-controlled mechanism is introduced to deactivate, activate, or reconfigure RFID tags using mechanical or manual means, ensuring selective data exchange by encapsulating sensors and providing physical or digital confirmation, allowing for improved data management and communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If RFID tags are deployed for tracking and monitoring products, then inventory and supply chain management efficiency is improved, but user control over data activation and management is lost leading to untimely or unauthorized interrogation

Engineering Contradiction:

Improveinventory and supply chain management efficiencyVSAvoiduser control over data activation

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by pre-configuring RFID tags with encapsulated sensors and multiple layers of protection (seals, covers) that prevent unauthorized activation. The tags are prepared in advance with controlled activation mechanisms that require specific user actions (breaking seals, removing covers) to initiate data exchange, ensuring data is only activated when intended by the user.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces intermediary protective elements (encapsulation layers, seals, covers) between the RFID tag sensor and the external environment. These intermediaries physically protect the sensor and control access to the tag, requiring deliberate user action to remove or break the protection layers before data activation, thus preventing unauthorized interrogation while maintaining operational efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If RFID tags with sensors are activated for data collection, then data communication capability is enhanced, but unauthorized or untimely interrogation occurs compromising data management security

Engineering Contradiction:

Improvedata communication capabilityVSAvoiddata management security

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The system applies beforehand cushioning by implementing multiple protective layers (encapsulation, seals, covers) that cushion against unauthorized access attempts. These protective measures are in place before any data activation attempt, providing a buffer that prevents unauthorized interrogation while allowing legitimate user activation when needed.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The patent applies preliminary anti-action by pre-establishing protective barriers and activation controls that counteract potential unauthorized access. The encapsulated sensors and required activation steps create a preliminary defense mechanism that actively prevents unauthorized interrogation before it can occur, ensuring data security while maintaining communication capability.

Inventive Principle:

Principle #9Preliminary anti-action

3Ease of operation

If mechanical or manual activation mechanisms are added to RFID tags, then user control and data management are improved, but device complexity increases

Engineering Contradiction:

Improveuser control over data activationVSAvoidtag structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the RFID tag structure into distinct functional layers: the base tag component, encapsulation layers, protective seals, and activation mechanisms. Each layer serves a specific function and can be independently managed. This segmentation allows the addition of control mechanisms without fundamentally redesigning the entire tag system, making the complexity manageable and the activation process user-friendly.

Inventive Principle:

Principle #1Segmentation

AI summary

A system and method to provide user marketing recommendations or suggestions based on an interaction between a user and a product, using a radio frequency tag in communication with the product, a radio frequency reader, and a computing device. A motion of the user detected by the radio frequency tag is used to generate a signal containing level of motion, which is utilized by the computing device to determine a level of user interaction and generate marketing information. Marketing information about how to use the product in a recipe is sent to the user interface device.
