Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional micro-optoelectronic systems are used in 5G networks, then the system structure is simple, but the system requires re-plugging for upgrades and configurations which reduces productivity and increases loss of time
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple service modes (100G CWDM4, 100G WDM PON, 200G WDM4) within the micro-optoelectronic system. The system预先 prepares different service configurations that can be activated online without physical re-plugging, thereby improving upgrade efficiency and eliminating time loss associated with manual re-plugging operations.
Solution Approach 2:
The patent applies dynamics by enabling the micro-optoelectronic system to dynamically switch between different service modes and configurations during operation. The system can adaptively adjust its functionality based on online configuration commands, transforming from a static fixed-function device to a dynamic reconfigurable system that supports continuous service upgrades without interruption.
2Adaptability or versatility
If dedicated MAC layer and CPRI service conversion are implemented as in 100G WDM PON solution, then service functionality is improved, but the system loses online upgrade and configuration capabilities
Solution Approach 1:
The patent implements universality by designing a multi-functional micro-optoelectronic system that can support multiple service modes (100G CWDM4, 100G WDM PON, 200G WDM4) within a single device. The system incorporates universal interfaces and a unified control architecture that enables both dedicated service functionality and online reconfigurability, allowing one system to perform multiple functions without requiring separate dedicated devices for each service type.
Solution Approach 2:
The system pre-configures multiple service modes and protocols within its architecture, including dedicated MAC layer and CPRI service conversion capabilities. These functions are prepared in advance but can be dynamically activated or deactivated through online configuration, maintaining both service functionality and upgrade accessibility simultaneously.
3Quantity of substance
If 100G CWDM4 solution is used, then fiber resource requirements are reduced, but online upgrade and configuration functions are completely lost
Solution Approach 1:
The patent applies dynamics by creating a reconfigurable optical system that can change its operational characteristics during runtime. The micro-optoelectronic system dynamically adjusts its service mode, wavelength configuration, and protocol handling based on online commands, enabling the system to adapt to different service requirements without requiring additional fiber resources or physical re-plugging.
Solution Approach 2:
The system utilizes parameter changes by allowing dynamic modification of operational parameters such as wavelength, data rate, and service protocol through online configuration. This enables the same physical infrastructure to support different service types and capacities by changing operational parameters rather than requiring physical reconfiguration or additional resources.
4Device complexity
If micro-optoelectronic system requires re-plugging for bottom-level upgrades, then device complexity is low, but ease of operation deteriorates due to manual intervention requirements
Solution Approach 1:
The patent implements self-service by enabling the micro-optoelectronic system to perform its own configuration and upgrade operations autonomously. The system includes built-in control logic that can receive online configuration commands and automatically adjust its operational parameters, service modes, and internal settings without requiring manual physical intervention. This self-service capability maintains relatively simple device architecture while dramatically improving ease of operation.
