Autonomous Transport Corridor Control for Obstacle-Aware Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomously moving transport systems face inefficiencies due to inflexible environmental sensors that lead to emergency stops or slowed travel in response to immobile and dynamically changing environments, limiting their productivity and safety.
Innovation Solution
The system divides the monitored zone into a travel corridor and one or more secondary corridors, allowing adaptive adjustment of travel parameters such as speed and steering based on object location and movement, enabling efficient navigation without collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If environmental sensors monitor protective fields to ensure safety, then safety is improved, but productivity deteriorates due to emergency stops and slowed travel
Solution Approach 1:
The monitored zone is divided into multiple zones (first monitored zone, second monitored zone, third monitored zone) with different safety requirements. Objects in the first monitored zone (direct travel path) trigger emergency stops, while objects in the second and third zones (peripheral areas) trigger speed reductions or route adaptations, allowing the system to maintain safety while reducing unnecessary stops and maintaining productivity
Solution Approach 2:
The system adapts travel parameters dynamically based on object location. Instead of a binary stop/go response, the system adjusts speed, steering angle, and acceleration differently depending on which monitored zone contains the detected object, enabling flexible response that maintains both safety and productivity
2Adaptability or versatility
If protective fields are switched to respond to different environments, then adaptability is improved, but device complexity increases due to cumbersome switching
Solution Approach 1:
The system uses dynamic zone assignment where the monitored zones and their associated response strategies are continuously adapted based on vehicle movement and environment. The control apparatus automatically adjusts which zone corresponds to which response level without requiring manual reconfiguration or complex switching mechanisms, achieving high adaptability with simplified control logic

AI summary
An autonomously moving transport system comprising a control apparatus, an obstacle recognition device and a drive unit, wherein the drive unit is configured to move the autonomously moving transport system along a travel route with a specific travel parameter. The obstacle recognition device is configured to detect an object in a monitored zone and to transmit corresponding object information to the control apparatus. The control apparatus is configured to divide the monitored zone into a travel corridor and at least one first secondary corridor. The control apparatus is configured to determine, based on the object information, whether the detected object is located in the travel corridor or in the at least one first secondary corridor. The control apparatus is configured to adapt a travel parameter differently when the object is in the first secondary corridor than when the object is located in the travel corridor.
