Solution Overview

Problem

RFID transponders often have predefined settings that are difficult to change, leading to limited functionality and non-optimal performance due to the need to comply with various country-specific regulations, resulting in increased development effort and potential violation of regulations.

Innovation Solution

A method and system for modifying RFID transponder settings during a communication session using a command from an RFID reader, allowing dynamic adjustment of parameters such as transmitter strength, frequency bandwidth, and internal state to ensure compliance with regional regulations while optimizing performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If RFID transponders use predefined settings to meet safety regulations in various countries, then regulatory compliance is ensured, but functionality is limited and development effort increases

Engineering Contradiction:
Improveregulatory complianceVSAvoidfunctionality
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic configuration of RFID transponder settings by introducing a controller that can modify parameters such as transmitter strength, frequency bandwidth, and internal state during operation. This allows the transponder to adapt its settings based on the communication session requirements and regulatory environment, resolving the contradiction between fixed regulatory compliance and flexible functionality.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If RFID transponders have fixed predefined settings, then device complexity is reduced, but adaptability to different regional regulations is limited

Engineering Contradiction:
Improvesettings configurationVSAvoidregional compliance
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent enables the RFID transponder to automatically configure its own settings by incorporating a controller that receives information about the desired operational parameters and autonomously adjusts the transponder's configuration. This self-service approach maintains simple device architecture while achieving high adaptability to different regional regulations without requiring complex pre-programming.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If RFID transponder settings are made modifiable during communication session, then functionality and performance are optimized, but risk of unauthorized changes increases

Engineering Contradiction:
Improveperformance optimizationVSAvoidconfiguration security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements a controlled modification mechanism where the controller receives feedback about the current communication session context and regulatory requirements before adjusting settings. This feedback loop ensures that modifications are made based on legitimate operational needs rather than unauthorized changes, maintaining security while enabling performance optimization.

Inventive Principle:
Principle #23Feedback
