Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-driving systems face inventory-related issues due to unintended reading of RFID tags on objects and shelves during navigation, leading to interference and delays in the packing and shipping process.
Innovation Solution
Integration of an RFID reader with a sensor surface facing upwardly and a built-in printer in self-driving systems, allowing for precise reading of RFID tags and automatic label printing, while also incorporating cameras and sensors for obstacle avoidance and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If RFID reader is integrated into self-driving system for object identification, then identification capability is improved, but unintended reading of RFID tags on objects and shelves causes interference and delays
Solution Approach 1:
The RFID reader's sensor surface is positioned to face upwardly, creating 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 distant shelves or passing objects are excluded from the reading field, thus preventing unintended readings and interference
Solution Approach 2:
The system performs RFID tag reading as a preliminary action before the packing and shipping processes begin. By identifying objects upfront through the upward-facing sensor, the system prepares necessary information in advance, enabling streamlined subsequent operations without delays caused by unexpected tag readings during the process
2Measurement precision
If RFID reader with upwardly facing sensor surface is used, then misreading of RFID tags is minimized, but device complexity increases due to integration of multiple components
Solution Approach 1:
The patent combines multiple functions into a single integrated console unit: the RFID reader, printer, and image sensing camera are all integrated into the console structure. This merging approach consolidates what would otherwise be separate complex subsystems into one unified component, reducing overall system complexity while maintaining precise RFID reading capability through the upwardly facing sensor surface
Solution Approach 2:
The console serves as a universal platform that performs multiple functions: RFID tag reading (via the upward-facing sensor), label printing, and image capture. This multi-functional design eliminates the need for separate dedicated devices for each function, simplifying the overall system architecture while ensuring precise RFID reading through the specifically oriented sensor surface

Function Achieved in This Case
This solution minimizes misreads of RFID tags, streamlines the packing and shipping process by enabling on-site labeling and packing, reducing overall shipping time and overhead costs, and enhancing operational efficiency in environments like warehouses and hospitals.
Implementation Method 1
a RFID reader coupled to the console, the RFID reader having a sensor surface operable to read RFID tags placed on, over, or directly over the sensor surface
