RFID Device Request Forwarding to Object Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
RFID devices embedded in objects are limited in the information they can store and process, making it difficult to respond to requests that require access to information not stored within the device, and they typically do not share information with the object they are connected to.
Innovation Solution
A method and system that allows an RFID device to receive requests and forward them to a component of the object, enabling the object to process and generate responses, which are then transmitted back to the RFID device, thereby allowing for more advanced request processing and information retrieval about the object's presence and characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the RFID device stores limited information locally, then the device complexity is reduced and manufacturing is easier, but the device cannot respond to requests requiring information not stored within it
Solution Approach 1:
The patent introduces an intermediary component (such as a processor or controller) that mediates between the RFID device and the object's information storage systems. This intermediary receives requests from the RFID device, retrieves appropriate information from the object's components, and formulates responses, thereby enabling the RFID device to access information beyond its own limited storage without significantly increasing the RFID device's complexity
Solution Approach 2:
The system is segmented into distinct functional components: the RFID device for receiving requests, an intermediary processing component for coordinating information retrieval, and object components for storing and providing information. This segmentation allows each component to specialize in specific tasks, improving overall request processing capability while keeping individual component complexities manageable
2Loss of information
If the RFID device and object do not share information, then security is maintained and user control is preserved, but comprehensive information retrieval about the object is not possible
Solution Approach 1:
The patent implements a feedback mechanism where the RFID device sends requests to object components, receives information responses, and can use this information to make decisions or provide responses to external readers. This controlled feedback loop enables information sharing when needed for comprehensive retrieval while maintaining security by allowing the system to control what information is shared and with whom
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the RFID device to provide comprehensive responses to requests beyond its stored information, enhancing the ability to manage and control the object's functionality and status, while maintaining security and user control.
Implementation Method 1
receiving a request as an incoming RF signal at the RFID device... transmitting the response as an outgoing RF signal from the RFID device
