Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If train route management is performed on the ground with extensive ground control, then train operation control can be achieved, but resource management complexity increases and timeliness deteriorates

Engineering Contradiction:
Improvetrain operation controlVSAvoidground equipment resource management
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides resource management into two levels: ground-level section resource management (coarse granularity) and train-level fine resource sharing (fine granularity). This segmentation allows the ground equipment to manage resources at a higher level while trains handle detailed resource allocation, reducing ground equipment complexity while maintaining control reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces train-to-train communication as an intermediary mechanism that enables direct resource negotiation between trains. This intermediary layer reduces the burden on ground equipment by allowing trains to autonomously coordinate resource sharing, thereby simplifying ground equipment while ensuring reliable control through decentralized coordination.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If all resources are managed at ground level, then centralized control is achieved, but implementation difficulty increases

Engineering Contradiction:
Improvecentralized controlVSAvoidimplementation difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent segments control functions between ground equipment (centralized section resource management) and trains (decentralized fine resource sharing). This segmentation maintains centralized control at the ground level while distributing implementation tasks to trains, reducing overall implementation difficulty.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent enables trains to autonomously negotiate and share resources through direct train-to-train communication. This self-service mechanism reduces the implementation burden on ground equipment while maintaining centralized oversight, making the system easier to implement.

Inventive Principle:
Principle #25Self-service

3Reliability

If extensive ground control is used for train route management, then train operation control can be maintained, but operation efficiency deteriorates

Engineering Contradiction:
Improvetrain operation controlVSAvoidtrain operation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent segments resource management into ground-level section management and train-level fine sharing. This segmentation enables trains to autonomously coordinate resource usage, reducing communication overhead with ground equipment and improving operation efficiency while maintaining control reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces train-to-train communication as an intermediary that enables direct resource coordination between trains. This intermediary mechanism reduces the timeliness impact of ground-based control by allowing trains to negotiate resources directly, thereby improving operation efficiency while maintaining reliable control.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A train operation control system and method based on train-ground coordination are provided. The system includes a dispatching center server, a resource management unit (RMU) for ground train control equipment, and on-board train control equipment (CC), wherein the dispatching center server is connected via communication to the on-board CC, and the on-board CC is connected via communication to the RMU for the ground train control equipment; and the RMU for the ground train control equipment and the on-board CC coordinatively complete resource management and implement train operation control, wherein the resource management is divided into two levels, at a first level, the RMU is responsible for performing the resource management in the unit of section, and at a second level, a preceding train and a succeeding train interact with each other via direct train-to-train communication, such that finer resource sharing in a section is achieved between the trains.
