Camera-Based Modular Shelving for Real-Time Package Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current package tracking systems face inefficiencies and errors due to the lack of real-time monitoring and incorrect loading of packages, leading to increased costs and logistical challenges in delivery processes.
Innovation Solution
A modular shelving system equipped with cameras and controllers that continuously track packages using optical sensors, allowing for real-time monitoring and accurate identification of package placement and movement, reducing human error and optimizing loading strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If barcode scanning is used for package tracking, then package identification is achieved, but real-time monitoring capability is lost
Solution Approach 1:
The camera captures images of packages on shelves before loading errors can occur or before the shipping personnel complete their work. This preliminary capture of state information allows the system to later detect whether packages were incorrectly loaded or misplaced without requiring continuous real-time monitoring during the entire loading process.
Solution Approach 2:
Instead of using physical barcodes that require manual scanning, the system creates digital copies of package locations through camera images. These image copies serve as permanent records of package positions, allowing verification of correct loading without requiring physical presence or manual scanning at each stage.
2Reliability
If manual package loading is performed without monitoring, then loading flexibility is maintained, but loading accuracy deteriorates
Solution Approach 1:
The camera system operates autonomously to monitor and verify package loading without requiring active intervention from shipping personnel. The system automatically captures images, stores them, and enables later verification, allowing the loading process to proceed with manual flexibility while simultaneously providing automated accuracy verification.
3Measurement precision
If RFID chips are placed on packages for tracking, then real-time tracking capability is achieved, but system cost and complexity increase
Solution Approach 1:
The patent replaces electronic RFID tracking hardware with an optical imaging system. Instead of using radio frequency chips and readers to track packages, the system uses cameras to capture visual images of package locations, substituting a complex electronic tracking infrastructure with a simpler optical documentation system that provides sufficient tracking precision for verification purposes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enhances package tracking accuracy and efficiency by providing real-time location data and reducing loading errors, thereby improving delivery processes and minimizing costs.
Implementation Method 1
a camera fixed at a distance from the at least one shelf such that a field of view of the camera faces the at least one shelf
Data Source
AI summary
A shelving system has at least one shelf, a camera fixed at a distance from the at least one shelf such that a field of view of the camera faces the at least one shelf and closely encompasses the at least one shelf, and a controller in communication with the camera. The controller has a processor adapted to receive images captured by the camera within the camera's field of view and to determine from the images whether a particular object has been placed on, moved, or removed from the at least one shelf.
