Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a plurality of base stations is installed to expand communication coverage, then the communication coverage is improved, but the number of base stations in no-signal state increases, leading to reduced bandwidth utilization efficiency
Solution Approach 1:
The patent combines multiple client signals into a single multiplexed signal using signal multiplexing units. When multiple base stations are deployed, their signals are merged and transmitted through a shared optical communication device, ensuring that even if some base stations are in no-signal state, the bandwidth is still effectively utilized by aggregating available signals.
Solution Approach 2:
The optical communication device is designed to handle multiple types of client signals (Ethernet, SDH, etc.) and can dynamically adjust its operation based on the presence or absence of signals from different base stations. This multi-functionality allows the system to maintain high bandwidth utilization regardless of the operational state of individual base stations.
2Stability of the object's composition
If empty frames are transmitted to maintain signal continuity, then signal continuity is improved, but the effective use of communication bandwidth is reduced
Solution Approach 1:
The patent extracts and identifies empty frames within the multiplexed signal using frame analysis units. Once detected, these empty frames are removed or replaced with valid data signals, ensuring signal continuity is maintained only when necessary, while maximizing bandwidth utilization by eliminating unnecessary empty transmissions.
Solution Approach 2:
The system continuously monitors the content of transmitted frames and provides feedback to the signal multiplexing units. When empty frames are detected, the feedback mechanism triggers dynamic adjustment of the signal composition, replacing empty frames with valid data or adjusting the multiplexing configuration to maintain signal continuity without wasting bandwidth.
3Quantity of substance
If the optical communication device receives data traffic exceeding the predetermined communication bandwidth, then the data transmission capacity is improved, but the bandwidth management complexity increases
Solution Approach 1:
The patent implements dynamic bandwidth management where the optical communication device can adaptively adjust its operation based on the actual data traffic load. When data traffic exceeds the predetermined bandwidth, the system dynamically reconfigures the signal multiplexing and demultiplexing processes, and adjusts buffer management to handle the excess traffic efficiently without requiring complex static allocation schemes.
Solution Approach 2:
The system changes operational parameters such as buffer sizes, signal multiplexing ratios, and transmission rates based on the actual data traffic conditions. When data traffic exceeds the predetermined bandwidth, parameters like buffer capacity and multiplexing configuration are adjusted to optimize bandwidth utilization and manage the increased data transmission capacity without proportionally increasing device complexity.
