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 the power level parameter of optical signals to encode multiple binary characters. Instead of using only the presence or absence of light pulses, the system varies the power levels to represent different data values, thereby increasing data throughput without requiring physical changes to the communication infrastructure
Solution Approach 2:
The invention introduces an additional encoding dimension by using power levels alongside traditional temporal encoding. By mapping sequences of binary characters to specific power levels, the system effectively adds a new dimension to the encoding space, allowing more information to be transmitted per signal unit
2Productivity
If power-based encoding is implemented to increase data throughput, then transmission efficiency improves, but the system requires sophisticated encoding and decoding mechanisms
Solution Approach 1:
The patent applies segmentation by dividing the encoding process into distinct stages: sequence segmentation (grouping binary characters into sequences), power level mapping (assigning power levels to segmented sequences), and transmission. This modular approach manages complexity by breaking down the sophisticated encoding mechanism into manageable, standardized components
Solution Approach 2:
The system performs preliminary actions by pre-defining mapping relationships between binary character sequences and power levels. These mappings are established beforehand through standardized protocols, allowing the encoding and decoding processes to operate efficiently without requiring complex real-time computations during transmission
3Loss of time
If repeated binary characters are mapped to higher power outputs for compression, then transmission efficiency increases, but power level management becomes more complex
Solution Approach 1:
The patent applies copying by creating standardized power level representations for repeated binary character sequences. Instead of transmitting each repeated character individually, the system copies the power level assignment pattern and applies it to sequences of repeated characters, reducing transmission time while managing power levels through predefined templates

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.
