Forklift Extension Zone Control for Collision-Aware Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial truck guidance systems in logistics facilities are limited in scope and fail to dynamically adapt to changing conditions, such as vehicle status, obstacles, and traffic density, which can lead to collisions and inefficient navigation.
Innovation Solution
A method that determines a dynamically adaptable industrial truck extension zone based on the truck's absolute position, orientation, speed, and environmental factors, using anchor nodes and wireless communication to transmit data for collision avoidance and efficient navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If industrial trucks move at the highest possible speed to transport goods quickly, then productivity increases, but collision risk increases
Solution Approach 1:
The system performs preliminary actions by determining the extension zone in advance based on predicted future positions. The extension zone is calculated considering the truck's current speed, direction, and deceleration characteristics, allowing the system to prepare safety zones before actual movement occurs, thus preventing collisions while maintaining high speeds
Solution Approach 2:
The extension zone is made dynamic and adaptable rather than static. It changes continuously based on the truck's motion state (speed, direction, acceleration), environmental factors (obstacles, traffic density), and operational context. This dynamic adjustment allows the safety zone to optimize between collision avoidance and movement efficiency
2Reliability
If driver assistance systems use locally limited zones to restrict operation, then safety in specific hazardous areas improves, but navigation efficiency decreases
Solution Approach 1:
The extension zone concept applies local quality by creating safety zones with different characteristics in different locations. Rather than uniform restrictions, the system determines specific extension zones based on local conditions such as hazardous areas, obstacle locations, and traffic density, allowing safe operation in high-risk zones while maintaining efficiency in low-risk areas
3Reliability
If the extension zone is determined dynamically based on vehicle state and environment, then collision avoidance improves, but system complexity increases
Solution Approach 1:
The system performs self-service by having each industrial truck determine its own extension zone independently based on its own sensor data, vehicle state, and local environment. This distributed approach eliminates the need for a complex central control system to calculate zones for all trucks, reducing overall system complexity while maintaining high collision avoidance capability
Solution Approach 2:
The extension zone determination system serves multiple functions simultaneously: it provides collision avoidance, defines safe operating boundaries, guides navigation, and adapts to different vehicle types and operational conditions. This multi-functionality reduces the need for separate specialized systems, thereby managing complexity

AI summary
The invention relates, inter alia, to a method for operating a forklift truck (20) in a goods logistics facility (10). It is provided that the absolute position of the forklift truck (20) within the goods logistics facility (10) is determined, and the driving orientation of the forklift truck (20) within the goods logistics facility (10) is determined. Depending on the determined absolute position and the determined driving orientation of the forklift truck (20) within the goods logistics facility (10), a dynamically adjustable and/or variable forklift truck extension zone (30) is determined, preferably at predetermined intervals.
