Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

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

Innovation Solution

A user-controlled mechanism is introduced to selectively deactivate, activate, or reconfigure RFID tags using mechanical or manual means, ensuring data confidentiality and enabling next-step data actions, such as product order placement and marketing recommendations, through a cover or material that encapsulates the sensor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If RFID tags are continuously active for tracking and monitoring products, then inventory management efficiency is improved, but data security and unauthorized interrogation risks increase

Engineering Contradiction:

Improveinventory management efficiencyVSAvoiddata security

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic control of RFID tag activation through user interface devices that can selectively activate or deactivate tags based on current operational needs. This allows the system to transition between active tracking mode and inactive security mode, resolving the contradiction between continuous monitoring efficiency and data security risks.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces an intermediary control system comprising user interface devices and processing logic that mediates between the RFID tags and the inventory management system. This intermediary layer provides authorized control over tag activation, preventing unauthorized interrogation while maintaining efficient inventory management through controlled access.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If RFID tags are activated for real-time product tracking, then supply chain visibility is improved, but energy consumption and device complexity increase

Engineering Contradiction:

Improvesupply chain visibilityVSAvoidtag energy consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic activation of RFID tags rather than continuous operation. Tags are activated at specific intervals or triggered by specific events (such as product movement or inventory checks), maintaining supply chain visibility while significantly reducing energy consumption compared to continuous operation.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system employs event-triggered activation where RFID tags automatically activate when specific conditions are met (such as being brought near a reader or detecting movement). This self-service approach eliminates the need for continuous power supply while maintaining visibility when needed.

Inventive Principle:

Principle #25Self-service

3Reliability

If user control mechanisms are added to manage tag activation, then data confidentiality is improved, but device complexity and ease of operation are worsened

Engineering Contradiction:

Improvedata confidentialityVSAvoidcontrol mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates user control functionality into existing user interface devices that are already part of the inventory management system. The same devices used for inventory queries and product information display are also used for tag activation control, avoiding additional complexity while maintaining data confidentiality.

Inventive Principle:

Principle #6Universality (Multi-functionality)
