Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-driving systems face issues with unintended RFID tag reading due to their design, leading to inventory-related problems and interference with objects along their route.
Innovation Solution
Integration of an RFID reader with a sensor surface facing upwardly and a built-in printer within the self-driving system, allowing for precise RFID tag reading and printing of shipping labels, while minimizing interference with other tags and enhancing object identification and obstacle avoidance capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If an RFID reader is integrated into the self-driving system, then object identification capability is improved, but unintended reading of RFID tags on objects and shelves along the route occurs causing inventory issues
Solution Approach 1:
The RFID reader's sensor surface is positioned facing upwardly to create a localized reading zone directly above the self-driving system. This directional orientation ensures that only RFID tags in the immediate vicinity (on objects being handled) are read, while tags on shelves or objects along the travel route are excluded from the reading zone, thereby preventing unintended inventory scans
2Measurement precision
If the RFID reader sensor surface faces upwardly, then reading of RFID tags on objects is improved, but reading range increases potentially causing interference with other tags
Solution Approach 1:
By orienting the sensor surface upwardly, the RFID reader creates a concentrated electromagnetic field directly above the device. This localized field configuration enhances reading precision for tags in the immediate vicinity while naturally limiting the reading range, thereby preventing interference with distant tags on shelves or other objects along the route
