Electrical Interface for Track-Bound Vehicle Head Module Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for connecting electrical components between the car body and head module of rail-bound vehicles are labor-intensive due to the need for laying and connecting electrical lines in cramped spaces, particularly after the two parts are assembled, which complicates meeting safety and fire protection requirements.
Innovation Solution
A rail-bound vehicle design featuring a mechanical interface with pre-assembled electrical plug connections, where electrical lines in the car body are terminated on one part of the plug connection and those in the head module on another, allowing for assembly of the plug connections at a later stage, simplifying the electrical connection process and reducing the complexity of cable management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical lines are laid and connected after the head module and car body are assembled, then fire protection requirements can be met by sealing openings, but the assembly work becomes relatively high due to cramped space conditions
Solution Approach 1:
The patent applies preliminary action by pre-assembling the electrical plug connections on both the head module side and car body side before the final assembly. The electrical lines are terminated on plug connections that are pre-installed on cross members, allowing the connections to be ready before the head module is mounted on the car body. This eliminates the need to perform cable laying and connection work in the cramped space after assembly, while still maintaining fire protection by sealing the openings.
2Reliability
If electrical lines are routed through openings with fire protection sealing, then fire safety is ensured, but the complexity of cable management increases in cramped spaces
Solution Approach 1:
The patent applies preliminary action by pre-terminating the electrical lines on plug connections before final assembly. The plug connections are pre-installed on cross members in the car body and on the head module, with electrical lines already routed and connected to these plugs. This preliminary preparation simplifies cable management by organizing the electrical connections before the cramped space conditions are encountered during final assembly, while fire safety is maintained through proper sealing of the openings.
3Reliability
If the car body and head module are assembled separately and then joined, then collision safety requirements can be met with deformable zones, but the electrical connection process becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-assembling the electrical plug connections on both the head module and car body before final assembly. The electrical lines are terminated on plug connections that are pre-installed on cross members, allowing the electrical connections to be ready before the head module is mounted on the car body. This preliminary preparation simplifies the electrical connection process by eliminating the need to perform cable laying and connection work after assembly in cramped spaces, while collision safety is maintained through the separate assembly with deformable zones in the head module.
