Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage and fulfilment systems face challenges in reliably determining the correct location of load handling devices operating in a workspace, particularly when communication is lost or devices become unresponsive.
Innovation Solution
A method and system that utilize image sensors to capture the workspace, map target image portions to target locations, and determine exclusion zones to prevent transport devices from entering specific areas, thereby ensuring safe operation and preventing collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image sensors and mapping systems are implemented to determine exclusion zones, then safety and collision prevention are improved, but device complexity and system cost increase
Solution Approach 1:
The patent introduces an intermediary system consisting of image sensors, processors, and mapping algorithms that act as a mediator between the transport devices and the workspace environment. This intermediary captures visual data, processes it through mapping algorithms, and generates exclusion zone information that guides device navigation, thereby improving safety without requiring direct complex communication between all system components
Solution Approach 2:
The patent replaces traditional mechanical collision avoidance systems with optical sensing and computational mapping. Instead of relying on physical sensors or mechanical interlocks, the system uses image capture devices and software-based exclusion zone determination to prevent collisions, reducing mechanical complexity while enhancing safety
2Reliability
If exclusion zones are determined and enforced to prevent collisions with unresponsive devices, then collision prevention is improved, but operational efficiency and productivity may deteriorate due to restricted movement areas
Solution Approach 1:
The patent implements dynamic exclusion zones that can be adjusted in real-time based on the workspace environment and device status. Rather than fixed restricted areas, the system continuously updates exclusion zone boundaries to match actual device locations and operational needs, allowing transport devices to efficiently navigate available spaces while maintaining collision prevention
Solution Approach 2:
The system incorporates feedback mechanisms where image sensors continuously monitor the workspace, detect unresponsive devices, and update exclusion zone information accordingly. This closed-loop feedback ensures that exclusion zones are maintained only where necessary for safety, allowing operational efficiency to be preserved in areas where no safety risks exist

AI summary
A method and system for assisting the controlling of movement of one or more transport devices operating in a workspace. The method involves obtaining an image representation of the workspace captured by one or more image sensors and a target image portion of the image representation of the workspace. The target image portion is mapped to a target location in the workspace. An exclusion zone in the workspace, comprising the target location, is determined based on the mapping. The exclusion zone in the workspace is to prohibit the one or more transport devices from entering. Exclusion zone data, representative of the exclusion zone, is outputted to a control system for implementing the exclusion zone in the workspace.
