Solution Overview
Problem
Adhesive RFID/optical labels can be destructive to surfaces and difficult to reuse, and existing manufacturing methods are not efficient for producing large quantities quickly.
Innovation Solution
A hang tag design featuring an RFID tag, a hole for hanging, and upper and lower portions separated by a perforation, manufactured on a web to minimize tackiness and allow easy separation, enabling efficient mass production and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adhesive labels are used to attach RFID tags, then the labels can be applied to surfaces, but the adhesive can be destructive to the surface and the label cannot be easily reused
Solution Approach 1:
The adhesive is extracted from the label structure and replaced with a mechanical attachment system. The label is designed to be attached without adhesive, allowing it to be applied and removed without damaging surfaces, and reused multiple times.
Solution Approach 2:
The label is segmented into separate components including a hang tag portion and a product information portion connected by a perforation. This segmentation allows the label to be applied to hanging hardware rather than directly to the product surface, eliminating adhesive damage while maintaining ease of application.
2Ease of operation
If adhesive labels are used, then the labels can be applied to products, but the labels are difficult to reuse
Solution Approach 1:
The adhesive is removed from the label design entirely, replacing it with a mechanical attachment method using hang tags and split rings. This extraction enables the label to be easily removed and reused on different products without residue or damage.
Solution Approach 2:
The label system transitions from a static adhesive bond to a dynamic mechanical attachment that can be easily assembled and disassembled. The hang tag with split ring allows the label to be dynamically attached and detached for reuse.
3Ease of manufacture
If traditional manufacturing methods are used for labels, then the production process is simple, but the manufacturing speed and efficiency are insufficient for large quantities
Solution Approach 1:
Multiple label components (hang tag, product information, RFID tag) are merged into a single integrated label structure that is manufactured as one piece on a continuous web. This combining allows for high-speed automated manufacturing while maintaining design complexity.
Solution Approach 2:
The label components are pre-assembled and pre-configured during the web manufacturing process, including pre-attaching the RFID tag and pre-forming the perforation and hang tag structure. This preliminary action enables rapid deployment and high-volume production without complex post-manufacturing assembly steps.

Function Achieved in This Case
The solution allows for the creation of RFID/optical labels that can be easily applied and removed without damaging surfaces, while enabling efficient mass production and reuse, addressing the limitations of adhesive labels and traditional manufacturing methods.
Implementation Method 1
For passive tags, a typical RFID reader/writer energizes transponder circuitry in the tag by transmitting a power signal

AI summary
A hang tag may be disclosed. The hang tag can include an RFID tag, a hole, and an upper and lower portion separated by a perforation. The hang tag can additionally be manufactured on a web whereby once the tag is removed from the web, substantially no tackiness may remain on the hang tag.
