Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an existing optical transceiver is used, then the device structure is simple, but it cannot simultaneously receive and transmit GPON, 10 G PON, and 50 G PON optical signals
Solution Approach 1:
The optical device is segmented into multiple independent functional modules: multiple laser emitters (first, second, third laser emitters) for different communication protocols, multiple optical receivers, and multiple filters (first filter group, second filter group, third filter group, fourth filter group). Each module handles a specific protocol (GPON, 10G PON, 50G PON), allowing the system to process multiple protocols simultaneously while maintaining manageable complexity through modular design.
Solution Approach 2:
The optical device is designed as a universal transceiver capable of simultaneously receiving and transmitting multiple communication protocols (GPON, 10G PON, 50G PON) through a single integrated unit. The housing integrates multiple laser emitters, optical receivers, and filters that work together to provide multi-protocol functionality, eliminating the need for separate transceivers for each protocol.
2Adaptability or versatility
If multiple filters are added to handle multiple protocols, then the adaptability improves, but the demultiplexing precision may deteriorate due to alignment errors
Solution Approach 1:
The filters are pre-adjusted to precise positions and angles before being fixed in the housing. The adjustment mechanisms allow for preliminary alignment of each filter (first filter group, second filter group, third filter group, fourth filter group) to ensure optimal demultiplexing performance before final installation, preventing alignment errors that would degrade precision.
Solution Approach 2:
Adjustment mechanisms serve as intermediaries between the filters and the housing, enabling precise positioning and alignment of each filter. These mechanisms allow for fine-tuning of filter positions and angles during assembly and maintenance, ensuring that demultiplexing precision is maintained while handling multiple protocols.
3Adaptability or versatility
If multiple laser emitters and receivers are integrated, then the multi-protocol capability is improved, but the device volume increases
Solution Approach 1:
Multiple laser emitters, optical receivers, and filter groups are nested within a single housing structure. The compact arrangement places the first laser emitter, second laser emitter, third laser emitter, first optical receiver, second optical receiver, third optical receiver, and multiple filter groups in a space-efficient configuration, reducing the overall device volume while maintaining multi-protocol functionality.
Solution Approach 2:
The patent merges multiple separate transceiver functions into a single integrated optical device. The housing combines multiple laser emitters, optical receivers, and filter groups that would traditionally require separate devices, achieving space savings through consolidation while providing simultaneous GPON, 10G PON, and 50G PON capabilities.
