Method for storing washing machine identification code in tag memory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for storing washing machine identification codes in electronic tags do not effectively prioritize and manage fabric attribute information, leading to inefficient storage and potential data overflow in the limited memory space of RFID tags.
Innovation Solution
A method that detects available storage space in the EPC memory of an RFID tag and stores the washing machine identification code accordingly, using different writing priorities for fabric attribute information, such as fabric material, color, category, and manufacturer data, ensuring key information is stored effectively and safely within the tag memory, conforming to the EPC Class1 Gen2 protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fabric attribute information is stored in the EPC memory of the RFID tag, then the identification code can be efficiently accessed, but the limited storage space may be exceeded causing data overflow
Solution Approach 1:
The patent segments the storage strategy by first attempting to store the washing machine identification code in the EPC memory, and if that space is insufficient, then storing it in the USER memory instead. This segmentation of storage locations resolves the contradiction between efficient access (EPC) and available space (USER), allowing the system to adapt to different storage capacity scenarios.
2Loss of information
If all fabric attribute information is stored with equal priority, then all data can be preserved, but critical information may be lost due to storage constraints
Solution Approach 1:
The patent applies local quality by assigning different writing priorities to different types of fabric attribute information. Critical information such as fabric material and color is given higher priority and stored first in the available space, while less critical information is stored subsequently or omitted if space is insufficient. This ensures that the most important data is preserved even when storage space is limited.

AI summary
The present disclosure discloses a method for storing a washing machine identification code in a tag memory, the washing machine identification code being for indicating fabric information, the tag memory including an EPC memory for storing an electronic product code for identifying a tag object and a USER memory for storing user-defined data. The method includes: detecting a storage space remained of the EPC memory of the tag memory; storing the washing machine identification code into the EPC memory if the storage space is enough to store the washing machine identification code; otherwise, storing the washing machine identification code into the USER memory. Meanwhile, different writing priorities are used for different types of fabric attribute information in the storage process, thus ensuring that the electronic tag memory can completely and effectively store the key information of fabric attributes and meeting the requirement of smart washing of the washing machine.
