Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional parity bit verification is used, then data transmission can be performed, but verification errors occur leading to unreliable data validation
Solution Approach 1:
The verification process is divided into multiple independent modular operations (first modular operation and second modular operation) that process different aspects of the parity bits separately, then combine results for comprehensive verification, reducing single-point failure risks
Solution Approach 2:
Multiple parity bits are introduced as intermediary elements between the data transmission and verification processes. These parity bits serve as mediators that enable cross-validation through multiple modular operations, improving verification accuracy without affecting the original data
2Measurement precision
If multiple modular operations are performed on parity bits, then verification accuracy improves, but computational complexity increases
Solution Approach 1:
The complex verification task is segmented into multiple simple modular operations that can be executed independently and in parallel. Each modular operation processes specific parity bits using straightforward arithmetic, avoiding the need for complex algorithms while achieving high verification accuracy
Solution Approach 2:
The verification system changes the parameter of using multiple different moduli (first modular operation with one modulus, second modular operation with another modulus) to transform a single complex verification problem into multiple simpler problems that are easier to solve and combine

AI summary
A data transmission parity device for verifying data transmitted from a first device through a data line to a second device includes a processor and a memory. The data line includes an N number of signal pins for transmitting data and an (N+1)th signal pin for transmitting parity information. The processor is configured to receive and obtain a signal value of the N+1 signal pins, calculate a first sum of the signal value of the N+1 signal pins and apply a first modular operation on the first sum, determine whether a result of the first modular operation is equal to zero, and control the second device to reject the data when the result of the first modular operation is not equal to zero. The first modular operation and the second modular operation are both (mod 2) operations.
