Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID tag manufacturing processes lack productivity, requiring individual metal wires for each tag and resulting in higher production costs and reduced efficiency.
Innovation Solution
A method involving a sheet-like insulating base with regions defined by cutting lines, where a single metal wire is disposed to form a pattern with curved portions and an RFID module is placed within the regions, allowing for the simultaneous manufacturing of multiple RFID tags with the same pattern by cutting along the defined lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual metal wires are used for each RFID tag, then each tag can be manufactured independently, but productivity decreases and production costs increase
Solution Approach 1:
Multiple RFID tags are manufactured simultaneously by disposing a single continuous metal wire across multiple regions on an insulating base, rather than using separate metal wires for each tag. This merging approach increases productivity while maintaining tag consistency through uniform manufacturing processes.
Solution Approach 2:
The insulating base is divided into multiple regions separated by cutting lines, allowing the continuous metal wire to be segmented into individual tag components during the cutting process. This segmentation enables efficient batch production while maintaining the integrity of each individual tag.
2Productivity
If a single metal wire is used across multiple regions, then productivity increases, but the complexity of wire pattern design increases
Solution Approach 1:
The metal wire includes curved portions (first and second curved portions) that reverse the direction of the wire, creating a U-shaped or serpentine pattern. This curved design allows the wire to efficiently cover multiple regions while maintaining manageable complexity and enabling smooth integration with the cutting lines.
Solution Approach 2:
The metal wire is disposed in a predetermined pattern with curved portions before the cutting process. This preliminary arrangement ensures that the wire pattern is optimized for both manufacturing efficiency and electromagnetic performance, reducing the need for complex adjustments during production.
3Loss of time
If multiple RFID modules are disposed simultaneously, then manufacturing time is reduced, but positioning precision within each region becomes more challenging
Solution Approach 1:
The insulating base is pre-divided into multiple regions with defined cutting lines, and the metal wire is pre-positioned in a specific pattern. RFID modules are then disposed in predetermined positions within each region, ensuring consistent positioning accuracy while enabling simultaneous manufacturing of multiple tags.

AI summary
An RFID tag includes a booster antenna, a feeding loop, an RFID module, and a sheet-like insulating base. The insulating base includes first and second sides that are opposite to each other. The booster antenna is comprised by one metal wire having one end on the first side of the insulating base and the other end on the second side of the insulating base and includes a first curved portion that reverses a direction of the metal wire extending from the one end and a second curved portion that reverses a direction of the metal wire, which is reversed by the first curved portion, to connect to the other end. Moreover, the RFID module is disposed in a region surrounded by the metal wire including the first curved portion and the second curved portion.
