Rail Car Side Screen Protector With Deflectable Bumpers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo protection devices for autorack railway vehicles are often cumbersome to install, expensive, and fail to provide comprehensive protection against damage from contact with interior structures, particularly exposed support posts and sidewalls.
Innovation Solution
The development of removably installable protectors with a body and outwardly disposed bumpers that can be securely fastened to the sidewall of autorack railway cars, providing a barrier between the cargo space and the sidewall to prevent damage from contact with interior structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior protection devices are installed to protect automobile doors from contacting autorack structures, then damage prevention is improved, but installation complexity and time consumption increase
Solution Approach 1:
The protection device is divided into modular components: a mounting bracket that attaches to the autorack sidewall and a separate protective bumper element. This segmentation allows for easier installation and replacement, reducing overall installation complexity while maintaining protection reliability
Solution Approach 2:
The protective bumper is designed as a replaceable component that can be quickly installed and removed. If damaged during loading operations, the entire protective element can be replaced rather than repaired, minimizing downtime and maintaining protection reliability without complex repair procedures
2Reliability
If protection devices are installed to cover all exposed structures, then comprehensive protection is improved, but material usage and cost increase
Solution Approach 1:
Protection is applied locally only at the sidewall areas where automobile doors are most likely to contact during loading. The mounting bracket positions the protective bumper at these critical zones rather than covering the entire autorack interior, achieving comprehensive protection where needed while minimizing material usage in non-critical areas
Solution Approach 2:
The protective bumper extends slightly beyond the minimum required coverage area to ensure complete protection of the sidewall structure. This partial excess action guarantees that even with door profile variations, the critical areas remain protected while avoiding excessive material usage throughout the entire structure
3Stability of the object's composition
If fixed protection structures are used to protect sidewalls, then protection stability is improved, but adaptability to different door profiles decreases
Solution Approach 1:
The protective bumper is designed with flexible mounting options and adjustable positioning capabilities. The mounting bracket allows the bumper to be positioned at different heights and angles to accommodate various door profiles, maintaining protection stability through secure attachment while achieving adaptability through adjustable configuration
Solution Approach 2:
The mounting bracket design incorporates multiple attachment points and adjustment mechanisms that allow the same protective device to effectively protect against different door types and profiles. This universal design enables one protection system to serve multiple functions across different loading scenarios while maintaining stable protection
4Area of stationary object
If optimal protection locations are selected to cover maximum area, then protection coverage is improved, but material efficiency decreases
Solution Approach 1:
The protective bumper is strategically positioned at the sidewall locations where door contact probability is highest during loading operations. This localized placement maximizes the effective protection coverage area at critical zones rather than uniformly distributing material across the entire sidewall, achieving optimal coverage with improved material efficiency

AI summary
A protector for a railway car interior, such as an autorack car designed to transport automobiles. The protector is installed on and covers the sidewall of a railway car to provide a barrier between the car and the sidewall to prevent damage to automobiles being transported in the rail car. The protector has two bumpers that are connected to a body and are deflectable to provide expanded zones of protection when contacted by an object. The protector may be provided in different lengths to provide a suitable span of coverage of a railway interior structure when the protectors are arranged adjacently, horizontally along a sidewall of the rail car at suitable heights to provide protection. The outwardly projecting bumpers provide a protective barrier between the automobile, such as a door panel, and the railway sidewall or other structure. A railcar configured with protectors also is provided.
