Solution Overview

Problem

Existing systems for coupling and uncoupling train coaches require manual effort for operating the bellows, making the process time-consuming and costly, especially when adjusting the number of coaches to match passenger demand.

Innovation Solution

The system integrates an automatic coupler with a controller that operates a latching actuator, allowing for automated coupling and uncoupling of coaches by controlling the locking mechanism and latching mechanism of the bellows, reducing manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual operation is used for coupling and uncoupling bellows, then the system is simpler, but the process becomes time-consuming and labor-intensive

Engineering Contradiction:
Improveautomation of bellows couplingVSAvoidcomplexity of coupling system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the bellows latching mechanism with the automatic coupler system, integrating multiple functions (mechanical coupling, electrical connection, and bellows latching) into a single automated operation sequence. The controller coordinates the coupling actuator and latching actuator to perform both operations automatically, eliminating manual intervention entirely.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system enables self-service operation where the automatic coupler and controller work together to autonomously perform the coupling and latching operations. The coupling actuator automatically engages the locking mechanism, and the latching actuator automatically secures the bellows, allowing the system to service itself without external manual operation.

Inventive Principle:
Principle #25Self-service

2Productivity

If automatic coupling is implemented, then operational efficiency improves, but the device complexity increases

Engineering Contradiction:
Improvecoupling speedVSAvoidcomplexity of automatic coupler system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The automatic coupler system is divided into distinct functional modules: the coupling actuator for mechanical engagement, the latching actuator for bellows securing, and the controller for coordination. This segmentation allows each component to be optimized independently while working together to achieve high-speed automated coupling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by pre-positioning the coupling components and bellows in readiness before the actual coupling operation. The controller prepares the actuators and ensures all components are aligned, enabling the coupling to occur rapidly when activated.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the number of coaches is increased to match peak demand, then passenger capacity improves, but energy consumption increases

Engineering Contradiction:
Improveflexibility in coach configurationVSAvoidenergy consumption
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The system enables dynamic reconfiguration of train composition by allowing rapid coupling and uncoupling of coaches. Trains can be dynamically adjusted to match varying passenger demand, transitioning between different coach configurations efficiently rather than operating with a fixed number of coaches throughout the day.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows change in the operational parameter of train composition by enabling quick modification of the number of coaches in service. During peak hours, additional coaches are coupled to increase capacity; during off-peak hours, coaches are uncoupled to reduce energy consumption, adapting the train configuration to match demand conditions.

Inventive Principle:
Principle #35Parameter changes
