Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the data transmission speed is maintained the same for all operations, then data transmission reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the transmission circuit configuration adjustable rather than fixed. The controller dynamically selects the number of active transmission circuits (1, 2, 4, or 8 slices) based on the operation type and data characteristics, allowing the system to adapt its power consumption and transmission reliability to match the actual needs of each operation.
Solution Approach 2:
The patent changes the parameter of transmission circuit activation status from a fixed state to a variable state. By modifying the number of active slices based on operation requirements, the system optimizes the balance between power consumption and transmission reliability, using more circuits only when necessary for high-reliability operations.
2Productivity
If more transmission circuits are activated, then data transmission speed is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the number of active transmission circuits based on the required data transmission speed. The controller selects from predefined configurations (1, 2, 4, or 8 slices) to match the bandwidth requirements of different operations, ensuring that transmission speed is optimized without unnecessarily consuming power.
Solution Approach 2:
The patent changes the operational parameter of transmission circuit activation from a static to a dynamic state. By adjusting the number of active slices according to bandwidth requirements, the system achieves optimal data transmission speed while minimizing power consumption for each specific operation type.
3Reliability
If the number of transmission circuits is increased, then signal integrity is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the transmission circuit into multiple independent slices that can be individually activated. This modular structure allows the system to achieve high signal integrity by activating multiple slices when needed, while maintaining lower complexity by only activating the necessary number of slices for each operation, rather than always maintaining all circuits active.
