Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing encoding/decoding schemes are used without polarity processing, then the device complexity is reduced, but the security and reliability of Ethernet data transmission deteriorates
Solution Approach 1:
The encoding function is divided into two independent parts: a polarity processing circuit that handles polarity conversion, and an encoder that performs encoding. This segmentation allows each component to be optimized independently, improving overall reliability without excessively increasing complexity.
Solution Approach 2:
Polarity processing is performed as a preliminary step before encoding. The polarity processing circuit converts incoming data to the required polarity format in advance, ensuring that the encoder receives properly formatted data, which enhances transmission security and reliability.
2Reliability
If polarity processing is added to ensure preset polarity, then the transmission reliability is improved, but the device complexity increases due to additional circuit components
Solution Approach 1:
The polarity processing circuit acts as an intermediary between the data source and the encoder. It mediates the polarity conversion process, ensuring data meets protocol requirements before encoding, thereby improving reliability with a dedicated intermediate component.
Solution Approach 2:
The polarity processing circuit changes the polarity parameter of the Ethernet data to match protocol requirements. By systematically handling polarity as a separate parameter transformation, the system achieves higher reliability while keeping the complexity manageable through parameter standardization.
3Manufacturing precision
If the encoder handles both encoding and polarity processing, then the device complexity is reduced, but the manufacturing precision and error rate worsen due to overburdening the encoder
Solution Approach 1:
The functions are segmented into polarity processing and encoding operations performed by separate circuits. This prevents the encoder from being overburdened with dual functions, maintaining high encoding accuracy and manufacturing precision while managing complexity through functional separation.

AI summary
An Ethernet data transmission circuit, an Ethernet data transmission system and an Ethernet data transmission method are provided. The Ethernet data transmission circuit includes: a polarity processing circuit for processing a polarity carried by Ethernet data into a preset polarity; and an encoder for receiving the Ethernet data and the preset polarity carried by the Ethernet data, and encoding the Ethernet data. On the one hand, the security of Ethernet in a transmission process can be improved; on the other hand, without increasing workload of the encoder, the polarity processing circuit of the Ethernet data transmission circuit can be used to process the Ethernet data to be with a preset polarity, to facilitate the encoder to code.
