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 bandwidth and transmission efficiency cannot be increased
Solution Approach 1:
The patent changes the parameter being used for encoding by utilizing transmission power levels in addition to temporal and spatial dimensions. By mapping binary characters to specific power levels (e.g., first power level for '0', second power level for '1'), the system increases bandwidth capacity without adding physical infrastructure, directly resolving the contradiction between productivity improvement and device complexity
Solution Approach 2:
The patent introduces a new dimension for data encoding by using power levels as an additional degree of freedom. Instead of only varying the presence or absence of light pulses in time, the system now varies power levels, effectively adding a dimensional layer to the encoding scheme that increases capacity without requiring additional hardware components
2Quantity of substance
If more devices are added to increase demand for optical communication bandwidth, then the need for bandwidth increases, but the existing optical communication path cannot handle the increased traffic
Solution Approach 1:
The patent increases transmission capacity by changing the encoding parameters to include power level variations. This allows the existing optical path to carry more data traffic by efficiently utilizing power level distinctions, directly addressing the contradiction between increasing data traffic volume and maintaining transmission capacity on existing infrastructure
3Productivity
If physical alterations are made to the optical communication path to increase bandwidth, then the transmission capacity increases, but the hardware configuration must be changed
Solution Approach 1:
The patent achieves increased transmission capacity solely through parameter changes in the encoding scheme (utilizing power levels) without any physical alterations to the optical communication path. This resolves the contradiction by improving productivity while maintaining ease of manufacture, as no hardware modifications are required
Solution Approach 2:
The patent creates a virtual expansion of capacity by using power level copying/mapping to represent multiple binary characters. Instead of physically adding more transmission channels, the system creates additional capacity through intelligent use of power level variations, avoiding hardware modifications 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.
