Sliding Rail Mounting Structure for Equipment Compartment Bottom Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting structures for equipment compartment bottom plates in rail vehicles require numerous bolts for connection, making mounting and maintenance cumbersome and inefficient.
Innovation Solution
A detachable mounting structure featuring sliding rails with recesses and protrusions on the bottom plate and skeleton lateral beam, respectively, allows for easy engagement and disengagement, reducing the number of connecting pieces and facilitating faster mounting and maintenance, while a pressing block assembly ensures secure positioning and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sets of bolts are provided to ensure reliable mounting of the bottom plate, then the connection reliability between the bottom plate and the skeleton lateral beam is improved, but the device complexity and maintenance workload increase significantly
Solution Approach 1:
The patent combines multiple separate bolts into a single integrated sliding rail component. The sliding rail incorporates multiple connection points and engagement features that simultaneously secure the bottom plate to the skeleton lateral beam at multiple locations, replacing the conventional approach of using multiple independent bolts.
Solution Approach 2:
The sliding rail is designed with segmented engagement features including multiple recesses and protrusions that can independently engage with corresponding features on the skeleton lateral beam. This segmentation allows the single component to provide multiple connection points equivalent to multiple bolts while maintaining structural integrity.
2Reliability
If multiple sets of bolts are used to fix the bottom plate, then the mounting reliability is improved, but the ease of operation during mounting and maintenance deteriorates
Solution Approach 1:
The patent merges multiple bolt operations into a single sliding rail installation operation. The sliding rail is designed to be installed as one component that simultaneously establishes multiple connection points, eliminating the need to individually install and tighten multiple separate bolts.
Solution Approach 2:
The sliding rail incorporates a sliding mechanism that allows for dynamic adjustment and easy engagement/disengagement. The rail can slide along the bottom plate and engage with the skeleton lateral beam through interlocking recesses and protrusions, enabling quick mounting and dismantling without complex fastening operations.
3Strength
If multiple sets of bolts are provided for connection, then the connection strength is improved, but the maintenance time and productivity are reduced
Solution Approach 1:
The patent combines multiple bolt connections into a single sliding rail assembly that maintains equivalent or superior connection strength. The sliding rail is designed with multiple engagement points and interlocking features that distribute loads across multiple locations, providing robust connection while enabling maintenance of the entire assembly through removal of a single component.

AI summary
A mounting structure for equipment compartment bottom plate is provided. The bottom plate is detachably connected to a skeleton boundary beam of the equipment compartment. A sliding rail is fixedly connected to a side of the bottom plate where the bottom plate is lap-jointed to a skeleton lateral beam of the equipment compartment. One of the sliding rail and the skeleton lateral beam is provided with a recess and the other is provided with a protrusion engaged with the recess. In the mounting structure, the connection of the bottom plate and the skeleton lateral beam is achieved by the engagement of the recess and the protrusion. Therefore, connecting pieces for connecting the bottom plate and the skeleton lateral beam are removed and the number of the connecting pieces is significantly reduced.
