Modular Rail Brake Interface for Unified Data and Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electro-hydraulic brake systems in rail vehicles face challenges due to non-uniform, project-dependent, and voltage-dependent interfaces, leading to complex wiring, limited functional expansions, and inability to transmit additional data, particularly diagnostic information, due to hard-wired connections.
Innovation Solution
A modular hydraulic brake system with a universal interface and transmission medium that allows for uniform data transmission between function modules and vehicle electronics, enabling flexible expansion and independent operation of function modules with standardized voltage supply, reducing the need for additional wiring and allowing for secure data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard-wired connections are used for data transmission between brake components and vehicle electronics, then reliable data transmission is achieved, but wiring complexity increases and functional expansion is limited
Solution Approach 1:
The patent implements a universal interface that combines multiple functions (data transmission, diagnostics, control) into a single standardized connection between brake components and vehicle electronics. This universal interface eliminates the need for separate hard-wired connections for different functions, reducing wiring complexity while maintaining reliable data transmission through a multi-functional communication protocol
Solution Approach 2:
The patent replaces mechanical hard-wired connections with an electronic communication system that transmits data, diagnostic information, and control signals through a standardized digital interface. This substitution eliminates physical wiring for diagnostic and control functions while maintaining reliable communication through error-checked data transmission protocols
2Adaptability or versatility
If project-dependent and voltage-dependent interfaces are used, then specific functional requirements are met, but adaptability to different configurations is reduced
Solution Approach 1:
The patent introduces a universal interface standard that can adapt to different functional requirements through software configuration rather than hardware customization. The standardized interface supports multiple voltage levels and functional modes, allowing the same physical connection to serve different brake system configurations without requiring project-specific interface designs
Solution Approach 2:
The patent enables adaptation to different functional requirements by changing operational parameters (voltage levels, data rates, communication protocols) of the universal interface rather than changing the physical interface itself. This allows a single standardized interface design to accommodate different voltage requirements and functional configurations through parameter adjustment
3Loss of information
If additional diagnostic data transmission is implemented, then system monitoring capability is improved, but existing communication channels become insufficient
Solution Approach 1:
The patent combines control data transmission and diagnostic data transmission into a single communication channel. The universal interface multiplexes different types of data (control commands, status information, diagnostic data) over the same communication medium, eliminating the need for separate dedicated lines for each function while maintaining complete information transmission
Solution Approach 2:
The universal communication interface is designed to handle multiple types of data traffic simultaneously, including control commands, status reports, and diagnostic information. This multi-functional communication channel replaces the need for separate specialized channels, reducing overall system complexity while improving diagnostic capability
