Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional optical fiber lateral output device is designed for a predetermined type of optical fiber core wire, then it achieves optimized performance for that specific type, but it lacks versatility and cannot handle various types of core wires
Solution Approach 1:
The device is designed with a universal clamping mechanism that can accommodate multiple types of optical fiber core wires (0.25mm, 0.5mm, and 0.9mm single core wires) through a single standardized interface. The clamping structure includes adjustable components that adapt to different core wire diameters while maintaining optimal bend geometry for light extraction.
Solution Approach 2:
The device enables dynamic adjustment of bending parameters including curvature radius, bend angle, and pressing force to match the optimal characteristics for each core wire type. The pressing unit can vary the applied force to achieve consistent bend quality across different core wire materials and diameters without requiring multiple dedicated devices.
2Manufacturing precision
If multiple dedicated devices are prepared for different core wire types, then each device achieves optimal performance for its specific target, but the device complexity and operational complexity increase
Solution Approach 1:
A single lateral output device integrates multiple functional capabilities to handle various core wire types through one unified system. The device includes a standardized clamping mechanism with adjustable parameters that can process 0.25mm, 0.5mm, and 0.9mm single core wires, eliminating the need for multiple dedicated devices and reducing overall system complexity.
Solution Approach 2:
The device incorporates dynamic adjustment mechanisms including variable pressing force control and adjustable clamping positions that can be modified in real-time based on the core wire type being processed. This dynamic adaptability allows one device to replace multiple static, dedicated devices.
3Manufacturing precision
If the operator changes the optical fiber lateral output device according to core wire type, then optimal performance is achieved for each type, but the operation time and productivity decrease
Solution Approach 1:
The device is pre-configured with standardized clamping geometries and pressing parameters that are optimized for common core wire types. The universal design allows operators to quickly adapt to different core wires without extensive reconfiguration, maintaining high binding efficiency while reducing setup time between different core wire types.
Solution Approach 2:
The pressing unit and clamping mechanism allow rapid adjustment of operational parameters such as pressing force magnitude and clamping position to match different core wire types. This quick parameter adjustment capability enables high productivity by eliminating the need for complete device changes while maintaining optimal binding efficiency for each core wire type.
