Solution Overview

Problem

In multimodal transport networks, passengers face challenges in minimizing journey time due to uncoordinated timetables across different monomodal networks, leading to prolonged waiting times and service disruptions, especially during vehicle delays or technical incidents.

Innovation Solution

A central supervision system that communicates with individual monomodal network operating systems to calculate and synchronize timetables, generate real-time traffic data, and modify operating rules to optimize passenger flow and service quality across interconnected networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If monomodal networks are managed independently by different operators with individual operating systems, then each network can be controlled according to its own operational constraints, but synchronization between networks is lost leading to prolonged passenger waiting times

Engineering Contradiction:
ImproveIndependent control of monomodal networksVSAvoidPassenger waiting time in connecting stations
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

A central supervision system is introduced as an intermediary between individual monomodal network operating systems. This central system receives real-time traffic data from multiple networks, calculates synchronized timetables considering interconnection constraints, and distributes modified operating rules back to the individual networks, thereby coordinating them without compromising their independent operational control

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent merges the operational supervision of multiple independent monomodal networks into a unified multimodal supervision framework. The central system combines traffic data from different networks and integrates timetable calculations across networks to achieve coordinated scheduling while maintaining the operational autonomy of each individual network

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If theoretical timetables are used for journey planning, then passengers can plan their trips in advance, but the timetables are not correlated between networks and may not be respected during vehicle delays

Engineering Contradiction:
ImproveTimetable adherenceVSAvoidReal-time response to delays and incidents
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system transitions from static theoretical timetables to dynamic real-time timetable adjustment. The central supervision system continuously receives actual traffic data, detects deviations and delays, and dynamically recalculates timetables for affected networks, ensuring that published schedules reflect current operational reality and can adapt to changing conditions

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A feedback mechanism is established where the central supervision system monitors actual vehicle positions and timetable adherence in real-time, compares them against planned schedules, and automatically triggers recalculations and rule modifications when deviations are detected, creating a closed-loop control system that ensures timetable reliability

Inventive Principle:
Principle #23Feedback

3Reliability

If a blockage occurs on one monomodal network, then that network experiences service disruption, but the impact spreads to other networks causing unforeseen congestion and extended passenger journeys

Engineering Contradiction:
ImproveService continuity on affected networkVSAvoidCongestion and delays on interconnected networks
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The system applies preliminary anti-action by proactively detecting service disruptions and automatically calculating compensatory timetable adjustments before they propagate through the network. When a blockage is detected on one monomodal network, the central supervision system immediately recalculates timetables for connecting networks to prevent passenger accumulation and secondary congestion

Inventive Principle:
Principle #9Preliminary anti-action

4Loss of time

If a central supervision system is introduced to coordinate multiple monomodal networks, then synchronization and service quality improve, but the system complexity increases

Engineering Contradiction:
ImprovePassenger journey timeVSAvoidSupervision system architecture
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The supervision system is segmented into modular functional components: a data collection module that receives traffic data from individual networks, a central calculation module that processes timetables and constraints, and a distribution module that communicates modifications back to networks. This segmentation allows the complex system to be built and operated as independent, manageable modules

Inventive Principle:
Principle #1Segmentation
