Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional optical encoding schemes are used, then the optical communication path can transmit data, but the bandwidth is limited and cannot be increased without physical alterations to the communication infrastructure
Solution Approach 1:
The patent applies parameter changes by utilizing multiple power levels of the optical signal to encode multiple bits per symbol. Instead of using only binary presence/absence of light, the system varies the power level parameter to represent different data values, thereby increasing bandwidth capacity without physical infrastructure changes
Solution Approach 2:
The invention introduces an additional dimension for data encoding by using power level amplitude alongside traditional temporal encoding. This dimensional expansion allows multiple bits to be encoded in each optical symbol, effectively increasing bandwidth without adding physical communication paths
2Productivity
If multiple power levels are used to encode repeated binary characters, then transmission throughput is enhanced, but the decoding complexity increases
Solution Approach 1:
The patent applies preliminary action by performing run-length encoding and power level mapping at the transmitter before optical transmission. This pre-processing organizes repeated binary characters into encoded sequences with associated power levels, simplifying the receiver's decoding task by providing structured input data
Solution Approach 2:
The invention replaces complex sequential decoding operations with parallel power level comparison and lookup operations at the receiver. By substituting mechanical/sequential processing with optical/electrical parallel comparison, the system achieves high throughput while maintaining manageable decoding complexity
3Productivity
If power output is used to encode binary characters, then additional data can be transmitted without hardware modification, but energy consumption increases
Solution Approach 1:
The patent applies partial action by using power level variations only for encoding repeated binary characters (runs) rather than every individual bit. This selective application of high-power encoding reduces overall energy consumption compared to transmitting every bit at maximum power, while still achieving increased data capacity
Solution Approach 2:
The invention merges multiple binary characters into single encoded symbols represented by power levels. By combining repeated bits into compact power-level-encoded representations, the system transmits more data per energy unit, improving energy efficiency while increasing transmission capacity

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.
