Solution Overview

Problem

Existing railway transport wagons for motor vehicles lack stability and efficiency during loading and unloading, particularly when extending a movable platform to an unloading ramp, necessitating additional equipment and prolonged loading/unloading times.

Innovation Solution

A railway transport wagon with a movable platform equipped with separate drive systems for beams with rollers, allowing for stable extension and retraction, featuring independent control of movement speeds and detachable linkage connections for versatile loading/unloading capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a movable platform is used for loading/unloading, then loading/unloading speed is improved, but stability during extension to unloading ramp deteriorates

Engineering Contradiction:
Improveloading/unloading speedVSAvoidstability during extension
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The movable platform is divided into two functional segments: the platform body for carrying vehicles and the extendable beams with rollers for reaching the unloading ramp. This segmentation allows the platform to maintain stability during extension while preserving high loading/unloading speed when the beams are extended to the ramp position.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The beams with rollers act as an intermediary element between the movable platform and the unloading ramp. These beams provide a stable connection and support structure that enables the platform to extend to the ramp while maintaining stability during the extension process and while vehicles are being loaded or unloaded.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If additional equipment like cranes is used for lifting containers, then loading/unloading capability is improved, but device complexity increases

Engineering Contradiction:
Improveloading/unloading capabilityVSAvoidneed for additional equipment
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The movable platform with extendable beams serves multiple functions: it acts as a vehicle carrier, an extendable bridge to the unloading ramp, and a stable support structure. This multi-functionality eliminates the need for separate cranes or additional lifting equipment, reducing device complexity while maintaining versatile loading/unloading capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The movable platform system is self-sufficient, using its own drive system to extend the beams and position the platform for loading and unloading operations. The system does not require external equipment such as cranes, thereby reducing overall device complexity while maintaining full loading/unloading capability.

Inventive Principle:
Principle #25Self-service

3Productivity

If the movable platform extends to the unloading ramp, then loading/unloading speed is improved, but reliability during extension deteriorates

Engineering Contradiction:
Improveloading/unloading speedVSAvoidstability during extension
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The beams with rollers are extended to the unloading ramp position before vehicles are loaded or unloaded. This preliminary extension ensures that the platform is already in the correct position and stable configuration, eliminating the need for adjustments during the loading/unloading process and thereby improving both speed and reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The beams with rollers serve as a stable intermediary structure that connects the movable platform to the unloading ramp. This intermediary provides reliable support and a fixed reference point, ensuring that the platform maintains stability during extension and throughout the loading/unloading operation, thus improving reliability while enabling high-speed operations.

Inventive Principle:
Principle #24Intermediary (Mediator)
