Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If software-based processing is used for handling mixed data frames, then data processing flexibility is improved, but processing speed and efficiency deteriorate
Solution Approach 1:
A hardware intermediary component is introduced between the serial bus system and network coupling elements. This intermediary performs automatic identification and routing of data frames (CAN vs Ethernet) at the hardware level, enabling fast processing while maintaining flexibility through dedicated hardware logic that can be configured for different data frame types without software intervention.
Solution Approach 2:
The patent replaces software-based data frame processing with a hardware-based processing mechanism. The hardware component directly intercepts and processes data frames on the bus, performing identification, extraction, and routing operations in hardware rather than through software execution, thereby achieving both high speed and flexibility through circuit-level logic.
2Adaptability or versatility
If indirect communication pathways are used for data transfer, then system compatibility is improved, but communication speed and efficiency deteriorate
Solution Approach 1:
The communication pathway is segmented into dedicated hardware channels: one path for CAN data frames and another for Ethernet data frames. The hardware intermediary automatically directs each data frame type through its optimized pathway directly to the appropriate network coupling element, eliminating indirect routing while maintaining compatibility with both communication protocols through separate dedicated paths.
3Productivity
If hardware-based direct exchange is implemented, then processing efficiency is improved, but device complexity deteriorates
Solution Approach 1:
The hardware intermediary is designed with multi-functionality to perform multiple operations within a single device: data frame interception, protocol identification, frame extraction, and directional routing. By consolidating these functions into one universal hardware component, the system achieves high processing efficiency without proportionally increasing overall device complexity, as the single component handles multiple tasks that would otherwise require separate devices.

AI summary
A computer-implemented method for processing data associated with a transmitter and/or receiver device for a serial bus system. The method includes: a) exchanging first data, for example using data frames of a first type, via the serial bus system, b) exchanging second data, for example using data frames of a second type, with at least one network coupling element, for example a switch.
