Rescue Coupler Segmentation for Manual Train Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rescue couplers are cumbersome, heavy, and difficult to adapt to the refined differences between different types of train couplers, with complex structures that complicate manual operation during rescue situations.
Innovation Solution
A rescue coupler design featuring a coupler body with a first coupling end, a second coupler hook, and a second coupling link, where the second coupler hook and link are arranged on the coupler body's sides, allowing for a detachable and arc-shaped structure that simplifies the design, reduces weight, and facilitates manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal rescue coupler with fixed structure is used to connect various types of train couplers, then adaptability to different coupler types is improved, but the structure becomes complex, size increases, and weight increases making coupling operation inconvenient
Solution Approach 1:
The rescue coupler is divided into multiple detachable components: a coupler body, a coupler hook, and a coupling link. These segments can be assembled and disassembled independently, allowing the rescue coupler to adapt to different train coupler types while keeping each component simple in structure and reducing overall complexity.
2Adaptability or versatility
If a universal rescue coupler with fixed structure is used to connect various types of train couplers, then adaptability to different coupler types is improved, but weight increases making coupling operation inconvenient
Solution Approach 1:
The coupler is segmented into separate components (coupler body, hook, and link) that can be stored independently. This segmentation reduces the weight that needs to be handled during coupling operations, as operators only need to attach the necessary components rather than maneuver a heavy fixed-structure coupler.
3Reliability
If existing rescue couplers with complex structures are used, then coupling functionality is achieved, but coupling operation becomes labor-consuming and difficult
Solution Approach 1:
The coupling link is designed to be detachable and movable, allowing operators to attach or remove it as needed. This dynamic design simplifies the coupling operation process, making it less labor-consuming while maintaining reliable coupling through the interlocking mechanism between the link and coupler body.
