Railway Stop Block With Adjustable Shims for Lateral and Vertical Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing railway track adjustment systems are complex, expensive, and require multiple stops and specific wedging for different rail types, making them inefficient and adaptable.
Innovation Solution
An abutment system with a block having a base surface and an upper surface relief, featuring lateral surfaces and a through opening for fastener passage, along with adjustable shims for lateral and vertical adjustments, allowing for simple, reversible, and adaptable positioning of rails on supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different stops are used to accommodate different rail types and positions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a single stop component that can accommodate multiple rail types (50E6, 60E1, and other profiles) through adjustable positioning mechanisms. The stop includes a block with a base surface, upper surface with relief forming housing, and lateral surfaces that can be adjusted laterally and vertically to fit different rail configurations, eliminating the need for multiple specialized stops.
Solution Approach 2:
The patent applies dynamics by incorporating adjustable shims that can be inserted or removed to modify the stop's lateral and vertical position. This dynamic adjustment capability allows the same stop structure to adapt to varying rail types and trajectories, transforming a static component into a flexible, multi-functional element.
2Manufacturing precision
If standard stops with specific shimming are used, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring the stop with a block structure that includes integrated lateral and vertical adjustment capabilities through shims. The shims are designed to be independently adjustable, allowing installers to achieve precise positioning without complex assembly procedures or specialized tools, thereby maintaining manufacturing precision while improving ease of operation.
3Adaptability or versatility
If adjustable stops are used, then adaptability is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies segmentation by dividing the adjustment function into independent lateral and vertical components. The stop block is designed with separate adjustment mechanisms for each dimension, using simple shims that can be independently inserted or removed. This segmentation simplifies the overall adjustment mechanism while maintaining full adjustability, reducing both complexity and cost.
