Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional optical encoding schemes are used, then the optical communication path can maintain existing hardware configurations, but the transmission bandwidth and efficiency are limited
Solution Approach 1:
The patent changes the parameter being used for encoding from traditional intensity modulation to optical power levels. By mapping binary characters to different power levels (e.g., first power level for '0', second power level for '1'), the system achieves higher transmission efficiency without requiring additional hardware components, thus resolving the contradiction between improving productivity and avoiding increased device complexity
Solution Approach 2:
The patent introduces a new dimension for data encoding by utilizing the power level dimension of optical signals. Instead of only using the presence/absence or intensity variation of light pulses, the system encodes information in the power level itself, effectively adding another degree of freedom to the transmission medium, which increases bandwidth without physical alterations to the optical path
2Productivity
If optical power levels are used to encode binary characters, then transmission efficiency is improved, but the system requires more sophisticated power level mapping and detection
Solution Approach 1:
The patent applies preliminary action by pre-mapping binary characters to specific power levels before transmission. The encoder预先 assigns the first power level to represent binary '0' and the second power level to represent binary '1', creating a deterministic mapping that simplifies the detection process at the receiver end, as the receiver only needs to detect which power level is present rather than decode complex modulation patterns

AI summary
A system for transmitting data over an optical communication path is configured to receive data to be encoded in a bitstream for transmission using an optical communication path and encodes the received data to obtain a bitstream. The system is further configured to determine that the bitstream includes a sequence of consecutive bits, and obtain a power level at which to transmit a portion of the bitstream based on a count of the consecutive bits in the sequence. The system may be configured to selectively activate a light source at a power level according to a modulation scheme to optically transmit the portion of the bitstream at the power level.
