Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a method change is carried out in an optical communication system to save power, then power consumption is reduced, but data communication must be stopped which increases risk and reduces reliability
Solution Approach 1:
The patent applies dynamics by making the optical signal transmission mode adjustable and switchable between multilevel mode and single-level mode. The system dynamically changes transmission parameters based on traffic conditions, allowing power-saving operation during low traffic while maintaining high-performance mode during high traffic, thus reducing power consumption without requiring system shutdown
Solution Approach 2:
The patent changes the transmission parameter (number of light intensity levels) to achieve power saving. By switching between multilevel optical signals (higher power consumption, higher data rate) and single-level optical signals (lower power consumption, lower data rate), the system optimizes power consumption according to actual traffic conditions while maintaining continuous operation
2Productivity
If multilevel optical signals are used for data transmission, then data transmission speed is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the transmission mode based on real-time traffic conditions. During high traffic periods, multilevel optical signals are used to maximize data transmission speed. During low traffic periods, the system switches to single-level optical signals to reduce power consumption, achieving adaptive optimization of both speed and energy usage
Solution Approach 2:
The patent implements periodic monitoring of traffic conditions and periodic switching between transmission modes. The determination unit periodically assesses whether to use multilevel or single-level signals based on current traffic load, creating a rhythm of high-performance and power-saving operation that responds to changing conditions

AI summary
A method of communication through a network, executed by a communication apparatus that performs transmission by selecting a transmission mode, the method includes determining whether to transmit the data in either a first mode or a second mode when transmitting data; transmitting the data using a predetermined number of kinds of optical signals having different levels in light intensity when determined to transmit in the first mode; and transmitting the data using a fewer number of kinds of optical signals having different levels in light intensity than the predetermined number when determined to transmit in the second mode.
