Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data exchange speed is increased to several Gbps using high-speed interface, then transmission capacity is improved, but the possibility of erroneous operations increases at high clock frequencies
Solution Approach 1:
The patent segments the transmission signal into multiple parallel lanes (e.g., 2 lanes for 10Gb/s, 4 lanes for 20Gb/s, 8 lanes for 40Gb/s). Each lane operates at a lower clock frequency, reducing the possibility of erroneous operations while collectively achieving high transmission capacity through parallel data transmission.
Solution Approach 2:
The patent transitions from single-serial transmission to parallel transmission by adding the dimension of multiple signal lanes. This allows the system to achieve high transmission capacity not by increasing the clock frequency of a single channel, but by multiplying the number of simultaneous transmission channels.
2Productivity
If transmission capacity is increased using more voltage levels, then data exchange speed is improved, but device complexity increases
Solution Approach 1:
Instead of increasing voltage levels within a single channel, the patent segments the transmission into multiple lanes, each using simple binary voltage levels (0V and 1.5V). This maintains signal simplicity while achieving higher capacity through parallelism.
Solution Approach 2:
The patent creates multiple copies of the transmission channel (parallel lanes), each transmitting independent data streams. This copying approach increases capacity without requiring complex signal modulation, as each lane uses the same simple voltage level scheme.
