Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a control signal is superimposed as AMCC in a low-frequency band between user devices, then the control signal can be transmitted without interfering with the main signal, but it becomes difficult for other devices to superimpose new control signals on the main signal during communication
Solution Approach 1:
The control signal is segmented into intermittent burst signals that are superimposed on the main signal at specific timing intervals. The detector segments the incoming signal to identify rising/falling edges, and the optical modulator segments the superimposition process to occur only during appropriate time windows, enabling multiple control signals to be multiplexed without continuous interference
Solution Approach 2:
The system employs periodic action by detecting rising or falling edges of control signals and superimposing new control signals at these periodic intervals. This timing-based periodic superimposition allows multiple control signals to share the same communication channel without conflict, as each superimposition occurs at a predetermined timing point in the signal cycle
2Adaptability or versatility
If control signals are transmitted as continuous AMCC between user devices, then reliable control signal reception is achieved, but the system cannot accommodate new control signals from other devices during ongoing communication
Solution Approach 1:
The system performs preliminary detection of rising or falling edges in the incoming control signal before superimposing a new control signal. This preliminary action ensures that the new control signal is only superimposed when the channel is appropriately clear or at a valid timing point, maintaining reliability while enabling adaptability
Solution Approach 2:
The detector acts as an intermediary that monitors the incoming control signal and triggers the optical modulator only when specific conditions (rising/falling edges) are detected. This intermediary mechanism ensures that new control signals are superimposed at appropriate moments, maintaining transmission reliability while enabling flexible control signal addition
