Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing railway track supports using prefabricated concrete modules are complex, costly, and time-consuming, failing to enable rapid production and optimized logistics in replicating the track outline and linking manufacturing steps effectively.
Innovation Solution
A method involving a movable insertion machine that forms and equips prefabricated concrete elements with inserts near the installation zone, allowing for quick production and assembly of railway track supports, reducing transport distances, and ensuring precise alignment of rails and inserts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If prefabricated concrete modules are arranged side by side on prepared ground using existing methods, then the railway track support can be constructed, but the manufacturing process becomes complex, costly, and time-consuming
Solution Approach 1:
The insert is arranged in the fresh concrete block before the concrete dries, allowing the prefabricated element to be fully equipped with inserts during the manufacturing process itself. This preliminary action eliminates the need for separate insertion operations at the installation site, reducing both time and complexity while maintaining productivity
Solution Approach 2:
The patent combines multiple operations (concrete pouring, shaping, and insert arrangement) into a single integrated manufacturing process. The movable insertion machine performs insert arrangement while the concrete is still fresh, merging what would otherwise be separate manufacturing and installation steps into one coordinated operation, thereby simplifying the overall process
2Adaptability or versatility
If the insertion machine is fixed in position, then it can manufacture track supports, but it cannot adapt to multiple production zones or sites along the installation zone
Solution Approach 1:
The insertion machine is designed to be movable rather than fixed, allowing it to be relocated along the installation zone as needed. This dynamic capability enables the machine to serve multiple production zones and sites, significantly improving adaptability and versatility without creating substantial time losses, as the machine can be efficiently repositioned between production locations
3Productivity
If the installation zone is not fully prepared, then construction cannot begin, but this delays the entire project timeline
Solution Approach 1:
The prefabricated elements are manufactured and equipped with inserts in advance, in the production zone, while the installation zone is still being prepared. This preliminary manufacturing action allows construction activities to overlap with site preparation activities, eliminating idle waiting time and accelerating the overall project timeline without compromising installation quality
4Manufacturing precision
If inserts are not pre-positioned in fresh concrete, then they can be installed later, but alignment precision and positioning accuracy are compromised
Solution Approach 1:
The insert is arranged in the fresh concrete block while the concrete is still workable, allowing for precise positioning and alignment to be established during manufacturing. This preliminary positioning action ensures high manufacturing precision for insert placement, and subsequently simplifies the installation process by eliminating the need for complex field adjustment operations

Function Achieved in This Case
This approach enables rapid and efficient manufacturing of railway track supports with reduced immobilization time for the insertion machine, improved alignment of rail systems, and quicker installation, while optimizing logistics and aligning with the desired track outline.
Implementation Method 1
each insert is arranged in the corresponding fresh concrete block by vibrating the concrete around this insert during its movement, until it reaches a predefined position
