Solution Overview
Problem
Existing RFID label production systems lack flexibility in producing various layout aspects of RFID labels, leading to inconvenient user experiences due to fixed layout positions of RFID circuit elements and prints, poor print quality, and inefficiencies in handling the presence or absence of RFID circuit elements.
Innovation Solution
An apparatus that allows for print control based on the presence or absence of RFID circuit elements and their layout, enabling the production of RFID labels with various layout aspects by adjusting the position of the print and RFID circuit elements on the label, using a cartridge system with a base tape and a print-receiving tape that can be bonded together to create labels with customizable layouts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed layout system is used for RFID circuit elements and prints, then the production process is simple, but the layout flexibility and user convenience deteriorate
Solution Approach 1:
The patent implements dynamic layout adjustment by allowing the print head to reposition along the tape width direction based on detected RFID circuit element positions. The print position is no longer fixed but dynamically adjusted to achieve optimal spacing (0.5-2mm) from the RFID elements, enabling flexible layout configurations while maintaining production efficiency
Solution Approach 2:
The system changes the positional parameter of the print relative to the RFID circuit elements by detecting the actual RFID element position and calculating an adjusted print position. This parameter adjustment ensures proper spacing without requiring fixed layout designs, thereby improving adaptability while using existing production equipment
2Manufacturing precision
If the print position is fixed relative to the tape, then the printing process is efficient, but the print quality deteriorates when RFID circuit elements are present
Solution Approach 1:
The system uses a detection means to identify the position of RFID circuit elements on the tape, then feeds this information back to the print control mechanism. Based on this feedback, the print position is adjusted to maintain optimal spacing (0.5-2mm) from the RFID elements, ensuring high print quality without requiring multiple printing passes or rework
Solution Approach 2:
The system performs preliminary detection of RFID circuit element positions before the printing operation. This advance knowledge allows the print position to be pre-calculated and adjusted, preventing print quality issues before they occur and eliminating the need for corrective printing operations that would reduce productivity
3Area of stationary object
If the print is made close to the RFID circuit elements, then the label space is utilized efficiently, but the print quality and RFID performance deteriorate
Solution Approach 1:
The system dynamically adjusts the positional parameter between the print and RFID circuit elements to maintain an optimal spacing of 0.5-2mm. This parameter optimization balances space utilization with print quality and RFID performance, preventing both print degradation and RFID interference while maximizing the usable label area
