Mobile RFID Reader for Object Detection Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting objects using RFID data carriers require high personal effort and installation costs due to the need for multiple stationary readers with limited transmission ranges, making it inefficient for comprehensive detection.
Innovation Solution
A mobile reader with both a first interface for connecting with RFID data carriers and a second interface for network data transfer, allowing for continuous data collection and transfer as it moves within the data carrier environment, reducing the need for individual activation and increasing coverage with fewer devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple stationary readers are used to cover the entire data carrier environment, then detection coverage is improved, but device complexity and installation costs increase
Solution Approach 1:
The patent transforms the static detection system into a dynamic one by using mobile readers that move through the data carrier environment. Instead of having multiple fixed readers covering specific zones, a single mobile reader travels through different positions to detect all data carriers, reducing the number of devices needed while maintaining comprehensive coverage
Solution Approach 2:
The mobile reader is designed with dual functionality: it can detect RFID data carriers and simultaneously determine its own position using positioning data carriers. This multi-functionality allows a single device to perform what previously required multiple specialized readers, reducing system complexity
2Reliability
If multiple stationary readers are deployed to ensure complete detection, then detection coverage is improved, but installation effort and costs increase
Solution Approach 1:
The system replaces complex stationary infrastructure with simple mobile devices that can be freely moved. This eliminates the need for ceiling mounting, electrical installations, and precise positioning of multiple readers, significantly reducing installation effort and costs
Solution Approach 2:
The mobile reader autonomously determines its position by reading positioning data carriers and automatically associates detected objects with the correct location. This self-positioning capability eliminates the need for complex installation and calibration procedures that would be required for multiple stationary readers
3Device complexity
If handheld readers are used for each read operation, then device complexity is reduced, but personal effort and time consumption increase
Solution Approach 1:
The mobile reader operates continuously as it moves through the environment, automatically detecting data carriers without requiring manual activation for each read operation. This continuous operation eliminates the repetitive manual triggering that characterizes handheld reader usage
Solution Approach 2:
The system automatically associates detected objects with position information by having the mobile reader continuously determine its own position and link it with detected data carriers. This automated process eliminates the need for operators to manually record or associate object data with locations

AI summary
The invention relates to a method for detecting objects, comprising a plurality of RFID data carriers (DT1-DT9) designed as tags, one data carrier being assigned to each object and the data carriers forming an RFID data carrier population with a random distribution of the RFID data carriers in a data carrier vicinity and at least one mobile read device (R1-R5). The read device, in an active operating mode, moves between at least two different positions in the data carrier vicinity and receives object data or position data of the RFID data carriers that are within range of the read device, such that a data carrier association is made in the read device, in accordance with the position of the latter, between an RFID data carrier and the read device and an object data record or position data record is created and then said object data record or position data record is transmitted to a network interface (NS) within transmission range of the read device.
