Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for producing labels with chips are time-consuming and prone to errors, requiring separate devices for printing on the label surface and writing data to the chip, which increases operational inefficiency.
Innovation Solution
A portable label printer that integrates a print head module and an RFID antenna assembly, allowing for simultaneous printing on the label surface and data writing on the chip using radio frequency identification technology, eliminating the need for additional devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional label printer is used to print product information onto the label and then an RFID writing device is used to write data on the chip, then the label can be produced with both printed content and chip data, but the process becomes time-consuming and prone to errors
Solution Approach 1:
The patent combines the printing function and RFID data writing function into a single integrated label printer device. The print head module and RFID antenna assembly are integrated within the same device, allowing simultaneous or sequential operation without requiring separate devices. This merging eliminates the time loss and errors associated with transferring labels between a printer and an RFID writing device, directly resolving the technical contradiction between production speed and accuracy.
2Ease of manufacture
If separate devices are used for printing on the label surface and writing data to the chip, then each device can be optimized for its specific function, but the operational efficiency decreases
Solution Approach 1:
The label printer is designed as a multi-functional device that performs both printing and RFID data writing operations. The device includes a print head module for printing content onto the label surface and an RFID antenna assembly for writing data to the chip, both integrated within the same device structure. This multi-functionality maintains the optimization of each function while eliminating the need for separate devices, thereby improving operational efficiency and productivity.
3Adaptability or versatility
If multiple devices are used for label production, then specialized functions can be performed by each device, but the complexity of the operation increases
Solution Approach 1:
The patent integrates multiple specialized functions (printing and RFID data writing) into a single device. The print head module and RFID antenna assembly are combined within one device housing, with a control module that coordinates both functions. This integration reduces operational complexity by eliminating the need to operate and coordinate multiple separate devices, while still maintaining the specialized capabilities of each function through modular design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The portable label printer streamlines the process by directly writing data onto the chip after printing on the label surface, reducing errors and saving time, thus enhancing operational efficiency for logistics and other applications.
Implementation Method 1
The RFID antenna assembly is electrically connected to the RFID processing module, and performs data reading and data writing on the chip of the label
Data Source
AI summary
A portable label printer for printing content onto a surface of a label is provided. The label has a chip disposed therein. The portable label printer includes a main body, an RFID antenna assembly, a front cover unit, a back cover unit, and a print head module. The front and back cover units are disposed in the main body, and a paper exit port is formed between the front and back cover units. The RFID antenna assembly is disposed in the main body and adjacent to the paper exit port. The print head module is disposed in the main body and under the RFID antenna assembly. The label first passes through the print head module, and then passes through the RFID antenna assembly. When the label passes through the RFID antenna assembly, the RFID antenna assembly performs data reading or data writing on the chip of the label.
