Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple plug connectors and interface cards are used to support different message bus protocols (RS232, RS485, CAN), then the system can communicate with diverse onboard devices, but the device complexity and manufacturing complexity increase significantly
Solution Approach 1:
The patent implements a universal interface card that can operate in multiple modes (RS232, RS485, CAN) depending on configuration, replacing the need for separate dedicated hardware for each protocol. This multi-functional design reduces the number of physical components while maintaining broad protocol compatibility across different message bus standards.
Solution Approach 2:
The interface card's functionality is made dynamic through software configuration and hardware jumpers that can be adjusted to change the operational mode. This allows the same physical hardware to adapt its behavior and interface characteristics based on the required communication protocol, eliminating the need for static, protocol-specific hardware designs.
2Adaptability or versatility
If hardware jumpers are used to configure interfaces, then the system can be reconfigured for different protocols, but the reconfiguration process becomes time-consuming and error-prone
Solution Approach 1:
The patent replaces manual mechanical configuration (hardware jumpers) with automated software-based configuration. The interface card can be programmed and configured through software, eliminating the need for physical jumper installation and removal. This substitution of mechanical operations with software control dramatically reduces configuration time and eliminates human error associated with manual hardware manipulation.
Solution Approach 2:
The interface card incorporates self-configuration capabilities where the system can automatically detect the required protocol and configure itself, or be easily reconfigured through software without requiring manual hardware intervention. This self-service approach eliminates the time-consuming manual jumper adjustment process while maintaining full configurability for different protocols.
3Adaptability or versatility
If diagnostic PCs with multiple interface cards are used, then data from various message buses can be accessed, but the system complexity and cost increase
Solution Approach 1:
The patent consolidates multiple protocol-specific interface cards into a single universal interface card that can handle RS232, RS485, and CAN protocols. This merging of previously separate hardware components into one multi-functional unit reduces system complexity, decreases the number of cards required in the diagnostic PC, and maintains the ability to access all message bus types.
4Loss of information
If manual data retrieval using laptops and software is used, then fault information can be obtained, but the process requires temporary immobilization of rolling stock
Solution Approach 1:
The patent enables continuous data acquisition from rolling stock through the universal interface card that can be permanently installed in the diagnostic PC. This allows ongoing monitoring and fault detection without requiring temporary connections or immobilization of the rolling stock. The useful action of data retrieval becomes continuous rather than intermittent, eliminating downtime associated with manual diagnostic sessions.

AI summary
A device configured to process data comprised in data messages passing on message buses of a rolling stock comprises: a universal input interface receiving data messages complying with the three following physical layers: RS232; RS485; CAN. From the message buses, the data messages comprise data; a processing engine receiving a remote requested configuration comprising one or more processing rules; a standardizing unit decoding the data messages into standardized data streams in function of the remote requested configuration; and wherein the processing engine further applies one or more of the one or more processing rules of the standardized data streams in function of the remote requested configuration.
