Rail Vehicle Ceiling Fastening Profiles for Flexible Retrofitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for arranging and attaching devices in the roof area of rail vehicles are inflexible and costly, particularly due to the use of separate equipment carriers or closed inner ceiling containers, which are not easily adaptable for retrofitting or conversion during the long service life of rail vehicles.
Innovation Solution
A fastening device with parallel and oppositely arranged fastening profiles that provide multiple interfaces for flexible attachment of devices, partitions, and cross-connectors, allowing for local and variable arrangement of equipment, including air conditioning ducts, and enabling efficient cooling of electrical and electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate equipment carriers or closed inner ceiling containers are used to arrange devices in the roof area, then device arrangement is possible, but the number of mechanical parts increases and flexibility for retrofitting is reduced
Solution Approach 1:
The fastening profiles serve multiple functions: they provide structural support for the ceiling lining, offer attachment interfaces for devices and air conditioning ducts, and enable flexible positioning along their length. This multi-functionality eliminates the need for separate equipment carriers, reducing the number of mechanical parts while maintaining adaptability for device arrangement and retrofitting throughout the vehicle's service life.
2Productivity
If equipment carriers are attached independently of air conditioning ducts, then device installation is simplified, but the use of limited roof space is not optimized
Solution Approach 1:
The invention merges the attachment system for devices with the air conditioning duct support system into a single integrated fastening profile structure. The profiles are positioned to accommodate both devices and air conditioning ducts, allowing them to be installed together in a coordinated manner. This integration optimizes the use of limited roof space while the standardized interfaces maintain installation simplicity.
3Reliability
If multiple separate components are used for device attachment, then secure fastening is achieved, but costs increase due to production and installation complexity
Solution Approach 1:
The fastening profiles are segmented with multiple interfaces distributed along their length, allowing devices to be securely fastened at various positions. The profiles themselves can be produced as modular sections that are easy to manufacture and install. This segmentation provides secure fastening capability while reducing overall complexity compared to using multiple separate attachment components throughout the roof area.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces the number of mechanical parts required, enhances flexibility for device installation and retrofitting, and provides efficient cooling in the limited roof space, thereby reducing costs and improving adaptability over the vehicle's service life.
Implementation Method 1
the fastening profiles on a side facing the space each having a plurality of interfaces running parallel in the longitudinal direction of the fastening module for a locally flexible fastening of brackets, partitions and/or cross-connectors
Implementation Method 2
at least one of the plurality of interfaces of the at least one fastening profile serves to fasten the fastening profile itself in the interior ceiling area of the car body... the at least one fastening profile realizes at least parts of a functional element, wherein the functional element can be, for example, an air conditioning duct for supplying the interior of the car with cold and/or warm air. In particular, cold air flowing through the air-conditioning duct can advantageously contribute to the cooling of devices.
