Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing optical splitting/coupling devices use fixed connection configurations, then device functionality is ensured, but device complexity and cost increase due to needing separate backup devices for each configuration
Solution Approach 1:
The optical splitting/coupling device is designed with a standardized interface that can accommodate different connection configurations (2-fiber or 4-fiber connections) using the same physical device structure. This universal design allows a single device type to perform multiple configuration functions, eliminating the need for separate backup devices for each configuration type.
Solution Approach 2:
The device separates the connection interface from the core functional circuitry, allowing the same core device to support different connection configurations through interchangeable interface modules. This segmentation enables flexibility in configuration while maintaining a standardized core component that can be universally deployed.
2Stability of the object's composition
If existing optical splitting/coupling devices use fixed connection configurations, then connection stability is ensured, but cost increases due to inability to share backup devices
Solution Approach 1:
By designing a universal device that can operate in multiple connection configurations (2-fiber or 4-fiber), the system reduces the total number of devices needed for backup purposes. This universality maintains connection stability through standardized interfaces while reducing overall system cost by eliminating redundant specialized devices.
3Ease of operation
If optical splitting/coupling devices have different forms for different connections, then connection requirements are met, but adaptability decreases due to inability to share devices
Solution Approach 1:
The device incorporates a standardized interface design that can accommodate different connection types (2-fiber or 4-fiber configurations) without requiring different device forms. This universal interface approach maintains ease of operation for specific connection requirements while significantly improving adaptability and device shareability across different deployment scenarios.
Solution Approach 2:
The device design allows dynamic configuration adaptation where the same physical device can be configured for different connection types based on operational requirements. This dynamic capability enables a single device form to serve multiple connection purposes, enhancing both adaptability and ease of operation.
