Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If driverless transport vehicles navigate freely without track constraints, then mobility and flexibility are improved, but collision risk and traffic blockages increase
Solution Approach 1:
A central electronic computing installation acts as an intermediary between multiple driverless transport vehicles. This central system receives trajectory data from each vehicle, computes space requirements, detects overlaps that would cause collisions, and coordinates movements to prevent conflicts. The intermediary enables free navigation while maintaining safety through centralized oversight.
Solution Approach 2:
The system implements continuous feedback by having each driverless transport vehicle transmit its computed trajectory to the central electronic computing installation, which then provides coordination signals back to the vehicles. This closed-loop feedback mechanism allows real-time adjustment of vehicle paths to prevent collisions while maintaining flexible navigation.
2Productivity
If multiple driverless vehicles operate simultaneously in the same area, then system throughput is improved, but traffic coordination complexity increases
Solution Approach 1:
The patent merges the coordination function into a single central electronic computing installation that handles trajectory computation and conflict resolution for all vehicles. This consolidation approach enables multiple vehicles to operate simultaneously by providing unified coordination, preventing the system complexity from scaling linearly with the number of vehicles.
3Extent of automation
If vehicles compute their own trajectories independently, then vehicle autonomy is improved, but traffic conflicts and overlaps increase
Solution Approach 1:
The central electronic computing installation serves as an intermediary that receives independently computed trajectories from autonomous vehicles, analyzes them for conflicts, and provides coordination signals. This maintains vehicle autonomy in trajectory computation while preventing conflicts through centralized mediation.
Solution Approach 2:
The system performs preliminary action by having vehicles compute and transmit their intended trajectories to the central system before execution. The central installation then pre-analyzes these trajectories for potential conflicts and issues coordination signals in advance, preventing trajectory overlaps before they occur.

AI summary
The invention relates to a method for coordinating driverless transport vehicles (1, 2). A first trajectory (12) calculated by a first of the transport vehicles (1, 2) and a second trajectory (13), calculated by a second of the transport vehicles (1, 2), of the □ second transport vehicle (2) are received by means of a central computing device (8). A space requirement (10) of the first transport vehicle (1) along the first trajectory (12) and a second space requirement (11) of the second transport vehicle (2) along the second trajectory (13) are determined by means of the computing device (8). If it is determined by means of the computing device (8) that the S space requirements (10, 11) will at least partially overlap each other, the first or second transport vehicle (I, 2) is selected by means of □ the computing device (8), and a signal is transmitted to the selected transport vehicle (I, 2). The signal prompts the selected transport vehicle (1, 2) to change its movement along its trajectory (12, 13) and/or its trajectory (12, 13).
