Overhead Imaging Pallet Guidance System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in warehouse logistics lies in the inefficiency and accuracy of moving products from conveyor systems to pallets, particularly due to human error, time-consuming processes, and the risk of damage or misplacement of packages, which can lead to safety issues and logistical challenges in ensuring correct delivery.
Innovation Solution
An overhead imaging system using 2D cameras that read machine-readable identifiers on packages, providing real-time guidance and feedback to operators through visual, audible, and tactile signals to ensure correct placement on pallets, along with virtual pallet construction and foreign object detection, enhancing operational efficiency and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling of packages from conveyor to pallet is used, then workers have flexibility in handling, but placement accuracy decreases due to human error
Solution Approach 1:
The system uses overhead cameras to capture images of packages on the conveyor and pallet, processes these images to generate virtual representations, and provides real-time visual feedback to workers through a display system. This feedback loop enables workers to see the virtual pallet configuration and understand where packages should be placed, maintaining operational flexibility while significantly improving placement accuracy.
Solution Approach 2:
The system creates a virtual copy of the physical pallet and packages through image processing. The virtual pallet stack digitally represents the physical arrangement, allowing workers to view the intended configuration before placing packages. This virtual copying mechanism provides guidance without restricting manual handling operations.
2Manufacturing precision
If real-time imaging and processing system is implemented, then package placement accuracy improves, but system complexity increases
Solution Approach 1:
The overhead camera system serves multiple functions: capturing images of packages on the conveyor, capturing images of the physical pallet, generating virtual representations, and providing visual feedback to workers. This multi-functional approach consolidates what could be multiple separate systems into a single integrated solution, reducing overall complexity while maintaining high placement accuracy.
Solution Approach 2:
The system automatically processes images captured by the overhead cameras to generate virtual pallet stacks without requiring manual intervention. The image processing and virtual representation generation occur autonomously, reducing the operational complexity despite the advanced technology involved.
3Productivity
If virtual pallet construction is used, then pallet construction efficiency improves, but time for system processing increases
Solution Approach 1:
The system pre-generates the virtual pallet stack configuration based on the captured images and package information before the worker begins placing packages. This preliminary preparation of the visual guide allows workers to immediately start efficient package placement without delays during the process, improving overall productivity while keeping processing time minimal.
Data Source
AI summary
A system and computer-implemented method for pallet management and constructing a pallet stack may include generating a virtual pallet stack using virtual packages having sizes and shapes corresponding with known available actual packages. In response to identifying an actual package to be placed on a pallet, an indication may be provided to a worker where the identified actual package is to be placed on the pallet stack based on the location of a corresponding virtual package on the virtual pallet stack.
