Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a lens assembly with multiple bevels is used to split and direct light signals, then signal transmission efficiency and coupling efficiency are improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple optical functions (light splitting, directing, and coupling) into a single lens assembly with four bevels. The first bevel splits the light signal from the light emitting chip, the second bevel directs the first split light to the first optical fiber array, the third bevel directs light to the light receiving chip, and the fourth bevel directs the second split light to the light monitoring chip. This merging of functions into one component improves signal transmission efficiency while managing device complexity.
2Manufacturing precision
If preset angles are used to control light signal paths, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent employs four preset angles (first preset angle, second preset angle, third preset angle, and fourth preset angle) to precisely control the light signal paths through the bevels. These fixed angular parameters enable accurate positioning and direction of light signals to different chips and fiber arrays, improving manufacturing precision and optical alignment.
3Adaptability or versatility
If light signals are split into multiple paths, then adaptability is improved, but loss of energy increases
Solution Approach 1:
The patent divides the light signal from the light emitting chip into multiple paths using the first bevel, which splits it into first split light and second split light. The first split light is directed to the first optical fiber array for transmission, while the second split light is directed to the light monitoring chip for monitoring. This segmentation enables simultaneous transmission and monitoring functions, improving adaptability.
