Train Coupler Deflection Device Pivot Anchor Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupler deflection devices for train vehicles often require the coupler rod to accommodate drives, limiting design flexibility and increasing the risk of interference during movement.
Innovation Solution
A deflection device that interacts with the coupler pivot anchor instead of the coupler rod, allowing for a design that incorporates dampers or deformation elements without the need for drive attachments, and can be positioned horizontally above or below the coupler rod's plane of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drive is directly connected to the coupler rod, then the coupler rod can be actuated to swivel about the coupler pivot anchor, but the coupler rod design is constrained and requires attachment space for the drive
Solution Approach 1:
The drive is extracted from the coupler rod and relocated to interact with the coupler pivot anchor instead. This separation removes the constraint of drive attachment on the coupler rod, allowing the coupler rod to be designed with dampers or deformation elements without compromising drive integration
Solution Approach 2:
The coupler pivot anchor serves as an intermediary element between the drive and the coupler rod. The drive acts on the pivot anchor, which in turn enables the coupler rod to swivel, thereby eliminating the need for direct drive-coupler rod connection and the associated design constraints
2Ease of operation
If the drive is positioned in the horizontal plane of coupler rod movement, then it can directly actuate the coupler rod, but the coupler rod may hit drive elements during movement
Solution Approach 1:
The drive is repositioned from the horizontal plane to a vertical arrangement, either above or below the coupler rod's plane of movement. This dimensional shift eliminates potential interference between the coupler rod during its horizontal swiveling motion and the drive elements, ensuring reliable operation
