RFID Tag Fabrication via Dynamic Cutting Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RFID tag fabrication techniques do not allow for the adjustment of tag dimensions based on the size of the printed indicia, limiting the flexibility in forming characters or bar codes and making large numbers of characters difficult to visually inspect.
Innovation Solution
An RFID-tag fabricating apparatus that includes a substrate-accommodating device for tapes with printable surfaces, a printing device, a tag-tape forming device, and a tag-tape cutting device, allowing for the formation and cutting of RFID tags with varying lengths based on the size of the printed indicia, and a cartridge for removably mounting substrates to accommodate different dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional RFID tag fabrication techniques are used, then the tags can be produced with fixed dimensions, but the flexibility in adjusting tag size to match printed indicia dimensions is limited
Solution Approach 1:
The cutting device is configured to vary the cutting position along the tag tape based on the detected length of the printed indicium. The control unit dynamically adjusts the segment length by comparing the printed indicium length with the IC circuit portion length, enabling flexible tag size adaptation without fixed dimensional constraints
Solution Approach 2:
The system changes the physical parameter of tag length by adjusting the cutting position relative to the printed indicium size. The control unit modifies the segment length parameter based on the relationship between printed indicium length and IC circuit portion length, allowing tags to be fabricated in multiple sizes to match different printed indicia requirements
2Quantity of substance
If a relatively large number of characters are printed on the RFID tag, then more information can be displayed, but the maximum size of each character is limited making visual inspection difficult
Solution Approach 1:
The system dynamically adjusts the tag length to accommodate varying numbers of characters while maintaining optimal character size. By varying the segment length based on the printed indicium dimensions, the system ensures that tags with more characters still provide adequate visual inspection capability
Solution Approach 2:
The tag length parameter is changed to match the printed indicium length, which contains the characters to be displayed. This parameter adjustment ensures that the tag dimensions are optimized for the specific number and size of characters required, balancing information quantity with visual inspectability
3Ease of manufacture
If the dimensions of RFID tags are fixed without consideration of printed indicium size, then the fabrication process is simplified, but the relationship between tag size and printed indicium size cannot be optimized
Solution Approach 1:
The system performs preliminary detection of the printed indicium length before cutting the tag tape. The control unit uses this detected information to determine the appropriate segment length, ensuring that the tag dimensions are precisely matched to the printed indicium size before the actual cutting operation
Solution Approach 2:
The control unit receives feedback from the detection means regarding the printed indicium length and uses this information to adjust the cutting position and segment length. This feedback mechanism ensures that the tag dimensions are precisely controlled based on the actual printed indicium size, achieving manufacturing precision while maintaining ease of operation
