Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional railroad rail profiles have limitations in load capacity, stability, especially in curves and at high speeds, and require multiple models for varying loads, leading to inefficiencies and environmental impact.
Innovation Solution
A railroad rail profile with a double or triple web configuration, featuring laterally arranged webs with cutouts for wires and cables, enhancing stability and stress absorption, while maintaining mechanical strength and reducing material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional single web rail profile is used, then manufacturing is simple and cost is low, but stability at high speeds and in curves is insufficient
Solution Approach 1:
The rail web is segmented into multiple parallel webs (double web or triple web configuration) instead of a single monolithic web. This segmentation increases the moment of inertia and structural stability of the rail, particularly improving performance at high speeds and in curves while maintaining manufacturability through standard rolling processes.
2Strength
If rail profile is designed for heavy loads, then load capacity increases, but speed performance decreases
Solution Approach 1:
The invention transitions from a single web configuration to a multi-web configuration, adding dimensional complexity to the web structure. This dimensional change increases the moment of inertia and structural rigidity, enabling the rail to support heavier loads while maintaining the speed performance characteristics of lighter rails.
3Adaptability or versatility
If multiple single web models are used for different loads, then adaptability to various load conditions is achieved, but device complexity and resource consumption increase
Solution Approach 1:
The multi-web rail profile serves multiple functions: it can accommodate both light and heavy loads, provide enhanced stability at high speeds, and maintain curve performance. This universal design eliminates the need for multiple specialized rail models, allowing a single rail type to adapt to varying operational conditions through its inherent structural flexibility.
4Ease of manufacture
If conventional rail profile is used, then manufacturing is straightforward, but environmental impact increases due to frequent replacements
Solution Approach 1:
The invention applies partial modification to the conventional rail profile by introducing additional webs while maintaining the basic Vignole structure and manufacturing process. This partial action approach enhances rail longevity and reduces replacement frequency (thereby reducing environmental impact) without completely overhauling the manufacturing system, keeping it straightforward and compatible with existing infrastructure.

AI summary
A profile for the composition of a railroad rail with the provision for at least one pair of webs in each profile of the rail, in addition to being provided with a set of cutouts of a plurality of geometric shapes that allow the crossing of wires and cables for several purposes. The webs arranged more laterally to the center of the rail provide greater stability to the rail the plurality of holes enables greater capacity to absorb stresses and vibrations, consequently, greater stability for the train, especially at high speeds. The adopted geometries also present a greater mechanical strength in relation to common rail profiles compared to the same amount of used material.
