Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction of guide plates in bridge track beams is difficult and accuracy is hard to guarantee, leading to challenges in travel safety and increased costs due to complex structures and deformation issues.
Innovation Solution
A track beam design with a separate guide plate connected to the main component through a connecting structure, allowing for separate machining and selection of materials, reducing the need for thickening and temporary devices, and facilitating easier assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the web plate is thickened to ensure structural strength and stability, then the strength and stability are improved, but the amount of steel used increases and costs increase
Solution Approach 1:
The track beam is divided into a main component (web plate, top plate, bottom plate) and a separate guide component (guide plate). This segmentation allows the web plate to be optimized for structural strength while the guide plate is separately optimized for guiding accuracy, avoiding the need to thicken the web plate unnecessarily.
Solution Approach 2:
The guide plate is extracted from the web plate structure and made as a separate component connected by a connecting structure. This extraction allows the web plate to maintain its optimal thickness for structural strength while the guide plate provides the necessary guiding function, preventing over-design of the web plate thickness.
2Strength
If the web plate or guide plate is machined into a complex structure to connect them, then the connection strength is improved, but the machining difficulty increases and construction complexity increases
Solution Approach 1:
The connection system is segmented into a connecting structure that joins the guide plate to the web plate. This allows both the web plate and guide plate to be manufactured as simple, standardized components, reducing machining complexity while maintaining connection strength through the dedicated connecting structure.
Solution Approach 2:
A connecting structure serves as an intermediary component between the web plate and guide plate. This intermediary simplifies the connection process by providing a standardized interface, eliminating the need to machine complex connection features directly into the web plate or guide plate.
3Manufacturing precision
If a temporary device is added during construction to prevent deformation, then the manufacturing precision is improved, but the loss of time and material resources increases
Solution Approach 1:
By segmenting the guide plate from the web plate and providing a separate connecting structure, the guide plate can be positioned and connected in a way that inherently maintains guiding accuracy without requiring temporary support devices during construction.
Solution Approach 2:
The connecting structure is designed in advance to provide precise positioning and alignment of the guide plate relative to the web plate. This preliminary design ensures guiding accuracy is built into the structure itself, eliminating the need for temporary devices during construction.
4Manufacturing precision
If the web plate is machined to meet guiding accuracy requirements, then the guiding accuracy is improved, but the machining difficulty and costs increase
Solution Approach 1:
The guiding function is extracted from the web plate and assigned to a separate guide plate. This allows the web plate to be machined to standard tolerances for structural strength, while the guide plate is separately machined to the high precision required for guiding, avoiding unnecessary machining complexity of the web plate.
Solution Approach 2:
The guide plate acts as a separate, dedicated component that copies the guiding function from the web plate's original purpose. This allows the web plate to be simplified for structural strength while the guide plate provides the precise guiding surface, separating the structural and guiding manufacturing requirements.

AI summary
A track beam includes a main component and a guide component. The main component includes a top plate, a bottom plate, and a web plate. The bottom plate is disposed below the top plate, and the web plate is connected between the top plate and the bottom plate. The guide component includes a guide plate and a connecting structure. The guide plate is disposed between the top plate and the bottom plate. The guide plate includes a planar plate structure extending in a longitudinal direction and is spaced apart from the web plate in a transverse direction. The connecting structure is connected between the main component and the guide plate such that the guide plate is connected to the main component through the connecting structure.
