Chipless RFID Liner-Free Labels for Low-Waste Item Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional RFID systems require microchips, adding complexity and cost, and traditional labels generate waste due to the need for a removable liner, which is inefficient and environmentally harmful.
Innovation Solution
Integration of chipless RFID antennas on liner free labels that reflect electromagnetic signatures for identification, eliminating the need for microchips and liners, thus reducing waste and manufacturing costs while maintaining tracking capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional RFID microchips are used for item identification, then reliable tracking capability is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the RFID chip from the traditional RFID system, eliminating the microchip component while retaining the antenna and electromagnetic identification functionality. This reduces device complexity and manufacturing cost while maintaining reliable tracking capability through chipless RFID technology.
Solution Approach 2:
The patent employs disposable, inexpensive RFID tags without microchips for item identification. These simple antenna-based tags are cost-effective and can be easily applied to items, providing reliable tracking without the complexity and cost of reusable chip-based RFID systems.
2Ease of operation
If traditional labels with removable liners are used, then label application functionality is achieved, but material waste and environmental harm increase
Solution Approach 1:
The patent removes the liner component from traditional label structures, creating liner-free labels that apply directly to surfaces. This extraction of the unnecessary liner element eliminates the associated material waste and environmental harm while preserving the core label application functionality.
Solution Approach 2:
The patent eliminates the need to discard liners after label application. By using liner-free construction, the entire label can be applied to the item without separation, preventing the waste generation that occurs when liners are removed and discarded in traditional labeling systems.
3Stability of the object's composition
If traditional labels with liners are used, then label protection during storage is achieved, but manufacturing cost and processing time increase
Solution Approach 1:
The patent removes the liner component that provides protection during storage, instead relying on alternative protective measures or storage methods that do not require the liner. This simplifies manufacturing by eliminating the liner material and associated processing steps, reducing both cost and processing time while maintaining label integrity through different means.

AI summary
A chipless RFID-enabled liner free label includes a substrate with an RFID antenna on the substrate and adhesive applied to the same side. The RFID antenna may be purchased from a third party, printed with conductive ink, formed from transferred conductive foil, or created as a combination of printed ink and foil. The adhesive may be flood coated or applied in discontinuous and/or continuous patches or patterns. The labels may include printed sense marks, or the antenna itself may function as a sense mark. A roll of such labels provides waste reduction benefits through elimination of the liner while maintaining RFID functionality without requiring chips. This technology in a roll format offers a cost-effective alternative to traditional chip-based RFID labels while preserving tracking capabilities.
