Insulating Rail Brace Assembly for Joint Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-performance, non-metallic rail joints used in rail systems are expensive due to the need for specialized materials to withstand high tensile and flexural forces, and standard rail joints positioned at unsupported sections can lead to premature failure under stress.
Innovation Solution
A rail brace assembly with electrically insulating materials and fasteners is used to reinforce rail joints at unsupported sections, providing additional support and maintaining alignment while preventing excessive force on the joints, and includes a base plate and clips with insulating material to secure the rails without requiring removal of existing joints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-performance non-metallic joints are used to electrically isolate rail sections, then electrical isolation performance is improved, but cost increases significantly due to expensive specialized materials
Solution Approach 1:
The patent uses composite materials consisting of resin material bonding metal rail sections together, with electrically insulating material applied to the outer surfaces of the rail joint. This composite approach provides both mechanical strength from the metal components and electrical isolation from the insulating material coating, achieving reliable electrical isolation at lower cost than fully non-metallic joints.
2Ease of operation
If standard rail joints are positioned at unsupported sections to simplify installation, then ease of installation is improved, but reliability deteriorates due to premature failure under high stress
Solution Approach 1:
The patent introduces a rail brace assembly as an intermediary support structure positioned adjacent to the rail joint. This brace assembly includes support elements that contact and reinforce the rail sections near the joint, distributing the mechanical stress and preventing premature failure while allowing the joint to remain in the unsupported section for ease of installation.
3Device complexity
If rail joints are placed at unsupported sections to reduce complexity, then device complexity is reduced, but strength deteriorates due to excessive stress on the joint
Solution Approach 1:
The rail brace assembly acts as a mediator structure that provides additional support to the rail joint without requiring complex modifications to the joint itself. The brace assembly includes support elements positioned to contact and reinforce the rail sections, distributing loads and reducing stress on the joint while maintaining overall structural simplicity.
4Reliability
If existing rail joint components are removed to install reinforcement, then reliability of the reinforced joint is improved, but loss of substance increases due to removal of existing components
Solution Approach 1:
The rail brace assembly is designed to be installed in addition to existing joint components rather than requiring their removal. The support elements of the brace assembly are positioned to contact and reinforce the rail sections alongside the existing joints, providing reinforcement while preserving the original joint components and avoiding material loss.
