Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mirrors and via holes are formed in the optical wiring layer using conventional methods, then the optical waveguide board can be manufactured, but positional deviations occur between the smooth surface and via holes, reducing optical signal transmission efficiency
Solution Approach 1:
The supporting member is divided into distinct functional portions: a conduction portion for electrical connection and a smooth surface portion for optical reflection. This segmentation allows each portion to be optimized independently for its specific function, with the conduction portion providing precise electrical alignment and the smooth surface providing optimal optical reflection, thereby resolving the positional deviation issue between these components.
Solution Approach 2:
The supporting member serves multiple functions simultaneously: it provides mechanical support for the optical element, establishes electrical connection through the conduction portion, and enables optical signal reflection through the smooth surface portion. By integrating these functions into a single component, the invention eliminates positional deviations that would occur if these features were formed separately in the optical wiring layer.
2Productivity
If the optical waveguide board uses conventional wiring board structures, then manufacturing is straightforward, but transmission efficiency deteriorates at high operating speeds due to noise
Solution Approach 1:
The invention replaces conventional electrical signal transmission through wiring boards with optical signal transmission through the optical waveguide. By substituting electrical signals with optical signals, the system achieves higher transmission speeds and immunity to electromagnetic noise, thereby improving both productivity and reliability simultaneously.
Solution Approach 2:
The optical waveguide acts as an intermediary medium that converts electrical signals from the conduction portion into optical signals for transmission, and then converts them back to electrical signals at the receiving end. This intermediary optical transmission path eliminates the noise and interference problems associated with direct electrical wiring at high operating speeds.
