Dynamic IC Tag Data Management for Appliance State Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID technologies face limitations in providing users with the most needed information according to the usage conditions of electronic appliances, as the data stored in IC tags is fixed and not dynamically updated, and the systems lack the ability to respond to appliance states, leading to inconveniences in user interaction.
Innovation Solution
A data management device that detects the state of an electronic appliance and selects appropriate data from a storage unit based on predefined rules, storing this data in a contactless storage medium for immediate presentation to the user, ensuring that necessary information is always available and relevant to the appliance's current state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is stored in IC tags with fixed content, then data storage is simple and reliable, but the data cannot be dynamically updated to match appliance states or user needs
Solution Approach 1:
The patent applies dynamics by enabling the IC tag data to change from static to dynamic state. The tag data is updated based on appliance operational states (normal, error, maintenance modes) and user interaction history, allowing the same physical tag to present different information content depending on current conditions without requiring multiple physical tags
Solution Approach 2:
The system implements feedback mechanisms where the appliance state information is continuously monitored and fed back to update the IC tag content. The terminal device also provides feedback about user interactions, which triggers further data updates on the tag, creating a closed-loop system that adapts to both appliance state and user needs
2Loss of information
If all possible data is stored in the IC tag, then comprehensive information is available, but users cannot quickly find the most needed information and must search through extensive data sets
Solution Approach 1:
The patent extracts only the most relevant information from the complete data set and places it on the IC tag for immediate user access. Based on the appliance state and user profile, the system extracts specific error codes, maintenance instructions, or operational guidance and displays them prominently, while other comprehensive data remains available in the appliance memory or cloud for reference if needed
Solution Approach 2:
The system applies local quality by providing different information content to different users or in different contexts. The IC tag displays customized information tailored to the specific user's needs, appliance state, and usage pattern, rather than presenting uniform comprehensive data to all users
3Ease of operation
If the system stores only essential data in IC tags, then data access is fast and simple, but users may not access the most needed information according to their specific usage conditions
Solution Approach 1:
The system performs preliminary actions by pre-loading and organizing data on the IC tag based on predicted user needs and appliance state. Before the user actually queries for information, the system has already prepared and positioned the most relevant data on the tag, so when the user approaches, the needed information is immediately available without requiring complex real-time processing

AI summary
A data management device configured to manage data stored in a contactless storage medium mounted to an electronic apparatus has a data storage unit that stores a plurality of data units including information of the electronic apparatus, a state detection unit that detects a state of the electronic apparatus, a data selection unit that, by referring to selection rules associating states of the electronic apparatus with types of the data, selects data comprising information conforming with the electronic apparatus under a state detected by the state detection unit from the data storage unit, and a data management unit that stores the data selected by the data selection unit in the contactless storage medium.
