Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operations and timetable-coordinated mapping are used for same-platform transfer, then passenger transfer can be facilitated, but operational staff work pressure increases significantly and synchronization reliability decreases
Solution Approach 1:
The system enables automatic train association and schedule adjustment through computer algorithms. The central server automatically calculates optimal arrival and departure times, matches trains between lines, and adjusts schedules without manual intervention, allowing the system to self-regulate and maintain synchronization reliability
Solution Approach 2:
Manual mechanical operations by drivers and staff are replaced with automated computer-based control systems. The patent implements automatic train association algorithms and electronic schedule management that substitute human decision-making with computational processes, improving both reliability and reducing operational pressure
2Reliability
If long station dwell time is used to coordinate train schedules, then synchronized transfer can be achieved, but passenger waiting time increases and system efficiency decreases
Solution Approach 1:
The system dynamically adjusts station dwell times based on real-time train performance data, arrival predictions, and transfer requirements. Instead of using fixed long dwell times, the algorithm optimizes dwell duration for each specific train pairing, achieving synchronization while minimizing passenger waiting time and improving overall system efficiency
Solution Approach 2:
The patent changes the parameter of station dwell time from a fixed value to a dynamically optimized value. The system calculates optimal dwell times based on multiple factors including train early or delayed arrivals, transfer passenger flow, and subsequent train schedules, thereby achieving synchronization with reduced waiting time
3Productivity
If manual schedule coordination is used, then train arrivals can be managed, but the amount of time spent on manual operations increases and operational complexity increases
Solution Approach 1:
The patent merges train schedule management for multiple lines into a unified automated system. The central server consolidates schedule data from different lines and performs integrated train association calculations, reducing the complexity of manual coordination across multiple operations while improving overall management efficiency
Solution Approach 2:
An automated computer-based intermediary system is introduced between train operations and schedule management. The central server acts as an intermediary that receives train performance data, performs automatic association calculations, and generates adjusted schedules, eliminating the need for complex manual coordination processes
4Adaptability or versatility
If trains experience early or delayed arrivals, then operational flexibility is maintained, but synchronization between lines becomes difficult and work pressure on staff increases
Solution Approach 1:
The system implements continuous feedback loops where actual train arrival and departure data are fed back to the central server. The algorithm uses this feedback to recalculate optimal schedules in real-time, automatically adjusting to early or delayed arrivals while maintaining synchronization. This feedback mechanism preserves operational flexibility while making synchronization easier through automated adaptation

AI summary
The present invention relates to a train adjustment method for same-platform “automatic train protection”, a device, and a medium. The method includes the following steps: step A: an interaction process of predicted cross-line train running information, used to achieve real-time synchronous and periodic refresh of train schedule information of two lines; step B: an automatic train association process at a transfer station, using a “magnetic attraction algorithm” to associate and match trains; and step C: an automatic train association process at a non-transfer station. Compared with the prior art, the present invention has advantages of significantly alleviating the work stress of on-site personnel, enhancing the reliability of train control at the transfer station, more comprehensively ensuring passenger transfer convenience, reducing a considerable amount of waiting time at a platform, and the like.
