Pivoting Track Processing Machine for Confined Rail Workspaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing track processing machines are difficult to use in areas with limited processing space, such as switches and bridges, due to their fixed dimensions and lack of flexibility in orientation.
Innovation Solution
A track processing machine with a connecting unit that allows for mechanical adjustment of its longitudinal dimension along the axis of rotation, enabling pivoting of structural units between 70° to 90°, and a handle system for user-friendly operation, allowing the machine to be adapted to various orientations and spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the track processing machine has a fixed large longitudinal dimension, then it is easy to operate with vertical orientation, but it cannot be used in confined areas with limited working space
Solution Approach 1:
The connecting unit enables dynamic reconfiguration of the machine's longitudinal dimension by allowing pivoting between first and second components. This transforms the machine from a static fixed-dimension device to a dynamic adjustable-dimension device, resolving the contradiction between ease of operation and adaptability to confined spaces.
Solution Approach 2:
The machine is divided into separable first and second components connected by a connecting unit. This segmentation allows the components to be pivored relative to each other, enabling the longitudinal dimension to be reduced for confined areas while maintaining full functionality, thus resolving the contradiction between operational ease and spatial adaptability.
2Ease of manufacture
If the track processing machine has a fixed structure, then it is simple to manufacture, but it cannot be adapted to different orientations and working spaces
Solution Approach 1:
The connecting unit introduces a pivoting mechanism that allows the machine to dynamically change its orientation and longitudinal dimension. This dynamic capability is achieved through relatively simple mechanical means (connecting joints and pivoting components), maintaining ease of manufacture while significantly improving adaptability to different orientations and working spaces.
3Adaptability or versatility
If the longitudinal dimension is reduced for confined spaces, then the machine can be used in turnouts and bridges, but it becomes difficult to operate with vertical orientation
Solution Approach 1:
The machine dynamically adjusts its configuration based on operational needs. When vertical orientation is required for ease of operation, the connecting unit allows the components to pivot to restore the larger longitudinal dimension. When confined spaces are encountered, the components pivot to reduce the longitudinal dimension, thus resolving the contradiction between adaptability and operational ease.
Solution Approach 2:
The connecting unit with pivoting capability enables the machine to perform multiple functions: operating with vertical orientation in open areas and operating with horizontal or reduced-dimension orientation in confined areas. This multi-functionality resolves the contradiction by allowing the machine to adapt its configuration to different operational requirements.
