Engineering Contradiction Analysis
1Loss of energy
If conventional lenses and mirrors are used in optical interconnects, then device complexity is reduced, but optical losses increase significantly
Solution Approach 1:
The patent applies local quality by customizing the dimensions, curvature radii, and coating properties of each lens and mirror according to its specific position and function within the optical interconnect. Receivers have lenses optimized for capturing divergent light, while transmitters have lenses optimized for collimating light, with each component tailored to minimize optical losses at its specific location.
Solution Approach 2:
The patent implements parameter changes by varying the curvature radii, dimensions, and coating characteristics of optical components based on their functional requirements. Different curvature radii are assigned to lenses at different positions, and coatings are selectively applied to control reflectivity and transmission properties, thereby optimizing overall system performance.
2Loss of energy
If individually tailored lenses and mirrors are designed for specific functions, then optical losses are minimized, but manufacturing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the optical interconnect into distinct functional modules, each containing specifically tailored optical components. This modular approach allows each lens and mirror to be independently optimized for its function while simplifying the overall manufacturing process through standardized assembly procedures for customized components.
Solution Approach 2:
The patent implements preliminary action by pre-calculating and pre-designing the optimal dimensions, curvature radii, and coating specifications for each optical component before manufacturing. This upfront design phase ensures that components are manufactured with precise specifications that minimize optical losses, rather than requiring iterative adjustments during assembly or operation.
3Productivity
If conventional optical components are used, then ease of manufacture is maintained, but signal transmission efficiency deteriorates
Solution Approach 1:
The patent applies local quality by optimizing each optical component's properties for its specific function in the signal transmission path. Lenses at receivers are designed with specific curvature radii to efficiently capture divergent light, while transmitter lenses are optimized for collimation, with selective coatings applied to minimize reflections and maximize transmission at each interface.
Solution Approach 2:
The patent implements composite materials by combining different optical coating materials on lens and mirror surfaces to achieve desired optical properties. Multi-layer coatings are applied to control reflectivity, transmission, and anti-reflection characteristics, creating composite optical structures that outperform conventional single-material components.
