NFC-Enabled Fabric Tags for Reliable Data Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for affixing RF tags to fabrics, such as QR codes and RFID tags, face challenges including difficulty in capturing accurate images, inability to change encoded data, and aesthetic unappeal, while RFID tags lack interactive capabilities and are not designed for ongoing user experiences.
Innovation Solution
An NFC-configured RFID tag is sealed between water-resistant layers and securely affixed to fabric, allowing programming for interactive functions like directing electronic devices to web addresses, ensuring robustness and reliability through polyurethane vinyl layers and thermal transfer press application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If QR codes are used on fabric objects, then information can be encoded and displayed to users, but the code is visually unappealing and difficult to capture accurately under certain conditions
Solution Approach 1:
The patent replaces the visual QR code with an RFID tag that stores the same information (web address, product details) but in a different form - as electromagnetic data that can be read without visual capture. This eliminates the need for cameras and image processing while maintaining information accessibility.
Solution Approach 2:
The patent substitutes the mechanical/optical system of camera image capture with an electromagnetic field-based RFID reading system. Users interact with the product through proximity-based RF communication rather than visual scanning, eliminating capture difficulties under various lighting and angle conditions.
2Reliability
If RFID tags are integrated into garment labels, then inventory tracking and basic information encoding are enabled, but the tags lack interactive capabilities and are not designed for ongoing user experiences
Solution Approach 1:
The patent enhances the RFID tag to perform multiple functions beyond basic tracking: it stores web addresses for e-commerce integration, enables product authentication, provides care instructions, and facilitates ongoing user engagement. This multi-functional approach makes the tag adaptable to various user experience scenarios while maintaining reliable tracking.
Solution Approach 2:
The patent makes the RFID tag dynamic by enabling it to respond to user interactions in real-time. The tag can trigger different responses based on reading conditions, product state, and user device capabilities, transforming from a static information carrier to an interactive component that adapts to ongoing user experiences.
3Ease of manufacture
If RFID tags are affixed to fabric using conventional methods, then the tags can be applied to objects, but they are not securely attached and cannot withstand repeated wear and washing
Solution Approach 1:
The patent merges the RFID tag with the fabric label as a single integrated unit. The tag is embedded within or attached to the label structure, combining the functionality of both components into one durable assembly that maintains integrity through repeated wear and washing while simplifying the manufacturing process.
Data Source
AI summary
A RFID tag configured with a Near Field Communication (NFC) protocol is sealed between water-resistant layers and affixed to a fabric. The NFC-configured tag can be programmed with instructions to automatically direct an electronic device to a web address by which means virtually any additional information can be communicated to the user of the electronic device. According to a method aspect, the NFC-configured tag is initially sealed between water-resistant layers. A compatible water-resistant layer is affixed to a fabric and then the sealed NFC-configured tag and a further water-resistant cover layer are affixed to the fabric over the previously-affixed compatible layer. The tag is then securely and permanently affixed to the fabric, with which the tag can be safely subjected to repeated wear and washing.
