Solution Overview

Problem

Existing rail vehicle side wall cladding attachment methods require numerous screw connections, making assembly and disassembly labor-intensive and not vandal-proof, while existing solutions using profile rails and holders do not fully address the need for invisible and secure attachment.

Innovation Solution

A side wall cladding element with profile rails and holders that allow for flexible positioning and attachment to the rail vehicle's bodyshell, using a combination of clamping, screw connections, and hook-and-loop fasteners to provide secure and vandalism-proof attachment, enabling variable sizing and arrangement of cladding elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If numerous screw connections are used to attach side wall cladding elements to the body shell, then the attachment becomes vandalism-proof, but the assembly and disassembly work becomes labor-intensive

Engineering Contradiction:
Improvevandalism resistanceVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The attachment system is divided into modular components: profile rails mounted on the body shell, and holder elements that attach to both the profile rails and the cladding elements. This segmentation allows the cladding elements to be securely attached through multiple distributed connection points rather than requiring numerous individual screw connections across the entire surface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Profile rails and holder elements serve as intermediary components between the body shell and the cladding elements. These intermediaries provide structured attachment points that simplify the connection process while maintaining security, eliminating the need for direct numerous screw connections between the cladding and body shell.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If profile rails and holders are used to attach cladding elements, then assembly work is reduced, but the attachment may not be sufficiently invisible from the passenger compartment

Engineering Contradiction:
Improveassembly efficiencyVSAvoidvisibility of attachment components
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The profile rails are positioned and designed to be located in areas that are not visible from the passenger compartment interior. The attachment components are strategically placed on the outer surfaces or edges of the cladding elements, ensuring that while the attachment mechanism remains functional and secure, it remains aesthetically concealed from the passenger perspective.

Inventive Principle:
Principle #3Local quality

3Device complexity

If fixed-size cladding elements are used with limited holder positions on the body shell, then the attachment structure is simplified, but the ability to form different sizes and arrange cladding elements variably is restricted

Engineering Contradiction:
Improveattachment structure complexityVSAvoidcladding element sizing and arrangement flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The profile rails are designed as continuous or segmented linear structures that allow holders to be positioned at multiple locations along their length. This dynamic positioning capability enables cladding elements of various sizes to be attached at different intervals and arrangements along the vehicle body, providing flexibility without requiring a completely different attachment structure for each configuration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The profile rail and holder system serves multiple functions: it provides structural attachment, enables variable positioning of cladding elements, accommodates different cladding element sizes, and maintains a relatively simple overall structure. The same basic attachment mechanism can be used across different vehicle models and configurations, making the system universally applicable while maintaining adaptability.

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