Solution Overview

Problem

Existing train and tram inspection and maintenance platforms face issues with fixed height limitations, hindering access to various types of vehicles, and movable platforms are unstable and occupy significant space, hindering safe and efficient operations.

Innovation Solution

A machine with a sliding, H-shaped platform structure that adjusts height and extends a movable walkway to match the train or tram, incorporating lifting and locking mechanisms, perimetric delimitation, and fall prevention devices, allowing safe and flexible access to all parts of the vehicle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fixed platforms are used with extended walking surfaces, then operator safety is improved, but adaptability to different train heights deteriorates

Engineering Contradiction:
Improveoperator safetyVSAvoidadaptability to different train heights
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The platform is designed with movable supporting posts that can slide vertically along guide rails, allowing the platform to dynamically adjust its height to match different train or tram vehicles. This dynamic adjustment capability resolves the contradiction by enabling the platform to adapt to various heights while maintaining safety features.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The platform structure incorporates universal safety features including extended walking surfaces, handrails, and perimetric delimitation that can be adapted to different train types. The combination of height-adjustable supporting posts with standardized safety components creates a universal platform that serves multiple train models while ensuring operator safety.

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

2Adaptability or versatility

If movable platforms are used for height adjustment, then adaptability to different trains is improved, but stability deteriorates due to oscillations

Engineering Contradiction:
Improveheight adjustment capabilityVSAvoidplatform stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The supporting posts incorporate sliding mechanisms with controlled movement along guide rails, allowing height adjustment while maintaining stability during operation. The dynamic sliding capability enables adaptation to different train heights while the guided motion prevents unwanted oscillations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The platform includes locking mechanisms and perimetric delimitation systems that stabilize the platform structure once positioned at the desired height. These pre-designed stabilization features counteract potential oscillations and ensure platform stability during inspection operations.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Adaptability or versatility

If movable platforms are used for height adjustment, then adaptability to different trains is improved, but space occupation increases hindering access

Engineering Contradiction:
Improveheight adjustment capabilityVSAvoidspace occupation
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The platform is divided into modular components including multiple supporting posts that can be independently positioned and adjusted. This segmentation allows the platform to occupy minimal space while maintaining adaptability to different train heights through coordinated movement of individual modular elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The supporting posts slide along compact guide rails rather than requiring large movement spaces. This dynamic sliding mechanism enables height adjustment within a confined footprint, reducing the overall space occupation while maintaining full adaptability to different train or tram vehicles.

Inventive Principle:
Principle #15Dynamics
