Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for data transmission between track-bound vehicle units require significant design effort and mechanical cabling, limiting flexibility and efficiency, especially at the transition between vehicle units.
Innovation Solution
Data transmission is facilitated through a land-based data device using a higher-level communication network, which includes a server unit for managing and securing data, and wireless transmission using mobile radio standards like LTE, enabling communication between vehicle units without the need for direct cabling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired data transmission between vehicle units is implemented, then data can be transmitted between communication networks, but design complexity and mechanical cabling requirements increase significantly
Solution Approach 1:
The patent introduces a land-based data transmission system as an intermediary between vehicle units. Instead of direct wired connections between vehicle units, data is transmitted through land-based infrastructure (such as GSM-R or other mobile communication networks), which acts as a mediator to eliminate the need for complex mechanical cabling while ensuring reliable data transmission.
Solution Approach 2:
The patent replaces the mechanical cabling system with a wireless communication system. By substituting physical wired connections with land-based data transmission (mobile radio standards like LTE), the system eliminates the need for mechanical coupling and associated cabling complexity while maintaining data transmission functionality.
2Reliability
If mechanical coupling of vehicle units is implemented, then wired data transmission can be ensured, but flexibility and adaptability are reduced
Solution Approach 1:
The patent replaces mechanical coupling with wireless communication infrastructure. Vehicle units no longer need to be mechanically coupled to ensure data transmission, as land-based wireless networks provide the communication link. This enables greater flexibility in vehicle formation and deployment while maintaining reliable data transmission.
Solution Approach 2:
The land-based data transmission system serves multiple functions: it enables data transmission between any vehicle units regardless of their physical proximity or coupling status, supports both wired and wireless communication modes, and can be used across different vehicle configurations and operational scenarios, thereby providing universal adaptability.
3Reliability
If direct cabling between vehicle units is used, then data transmission is established, but efficiency and ease of operation are limited
Solution Approach 1:
The patent replaces manual cabling operations with automated wireless communication. Land-based data transmission systems automatically establish and maintain data connections between vehicle units without requiring manual intervention for physical connection setup, thereby significantly improving ease of operation while maintaining reliable data transmission.
