Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The maintenance and repair of rail vehicle components housed in containers, particularly those placed in the ceiling area, are hindered by limited access and reduced room height, and existing solutions do not optimize volume utilization effectively.

Innovation Solution

The containers are positioned in the cove area of the rail vehicle body, where they are adapted to fit the inner contour and face the side wall with their back and the roof with their top, allowing for better access and optimizing space by forming part of the interior paneling, and can be connected via pluggable interface components to create a continuous data connection and facilitate maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If containers are arranged in the ceiling area, then volume utilization is improved, but access to components for maintenance and repair deteriorates

Engineering Contradiction:

Improvevolume utilizationVSAvoidaccess to components

Core Design Contradiction:

Volume of moving objectVSEase of repair

Solution Approach 1:

The container is positioned in the cove area, utilizing the transition zone between the side wall and ceiling roof. This spatial repositioning allows components to be accessed from the side direction rather than requiring removal of ceiling panels, thus maintaining good accessibility while utilizing the ceiling-proximal space for volume optimization.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Volume of moving object

If containers are arranged in the ceiling area, then volume utilization is improved, but room height is reduced

Engineering Contradiction:

Improvevolume utilizationVSAvoidroom height

Core Design Contradiction:

Volume of moving objectVSLength of stationary object

Solution Approach 1:

The container shape is adapted to the inner contour of the cove area, creating a localized storage solution that utilizes the transition zone between side wall and ceiling. This localized placement optimizes volume usage in the cove region without extending into the main passenger compartment space, thereby preserving overall room height.

Inventive Principle:

Principle #3Local quality

3Ease of repair

If containers are placed in the cove area, then access to components is improved, but space utilization is optimized

Engineering Contradiction:

Improveaccess to componentsVSAvoidspace utilization

Core Design Contradiction:

Ease of repairVSVolume of moving object

Solution Approach 1:

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Quantity of substance

If multiple containers are arranged in the cove area, then component accommodation is improved, but device complexity increases

Engineering Contradiction:

Improvenumber of componentsVSAvoidcontainer configuration

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The container system is divided into multiple separable container units that can be independently installed and removed. Each container can accommodate specific rail vehicle components, and the modular design allows for flexible configuration based on the number and type of components needed, simplifying the overall system while increasing capacity.

Inventive Principle:

Principle #1Segmentation
