Wireless Tag Determination Unit for Data Transmission Optimization

Solution Overview

Problem

Existing wireless tag systems with built-in sensors face challenges in reducing data transmission volume, leading to prolonged communication times and rapid battery consumption, especially when handling large volumes of data, and lack determination capabilities within the wireless tags, necessitating the retrieval of entire temperature histories for monitoring temperature.

Innovation Solution

Incorporating a determination unit within the wireless tag to evaluate sensor data against criteria and transmit only the determination result instead of raw data, along with a communication control unit to manage data transmission efficiently, allowing for reduced data transfer and flexible communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the wireless tag transmits all raw sensor data to the reader/writer, then the reader can access complete information, but the communication time increases and battery consumption accelerates

Engineering Contradiction:

Improveinformation completenessVSAvoidcommunication time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The wireless tag performs preliminary determination of sensor data against stored criteria before transmission. The determination unit evaluates whether sensor data meets predetermined criteria and only transmits determination results rather than all raw data, reducing communication volume while maintaining necessary information.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts only the essential determination results from the complete sensor data set. Instead of transmitting all raw temperature data, the system extracts and transmits only the determination results (e.g., whether temperature exceeded thresholds), reducing data volume while preserving critical information.

Inventive Principle:

Principle #2Taking out (Extraction)

2Loss of information

If the wireless tag transmits all raw sensor data to the reader/writer, then the reader can access complete information, but the battery consumption increases

AI summary

A system comprising a wireless tag and a tag reader. The tag comprises: a sensor for generating a detected information; a storage for storing the detected information; a determination unit for storing a criteria information and outputting a result of determination on the detected information on the basis of the criteria information; and a communication control unit for transmitting the determination result in response to receiving a request. The reader transmits the request to the tag and receives the determination result from the tag.
