Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing optical modules with light separation parts face challenges in accurately positioning the optical receptacle due to obstruction by the divided reflection surface, requiring active positioning and increased time and manpower, which complicates the detection of the light-emitting surface and affects coupling efficiency.
Innovation Solution
The optical module is configured with a first optical device and a second optical device, where the first optical device is positioned without a light separation part to allow clear detection of the light-emitting surface, and the second optical device includes a light separation part with divided reflection and transmission surfaces to separate light into monitor and signal paths, facilitating easy alignment and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a light separation part with divided reflection surface is included in the optical receptacle, then the light can be separated into monitor light and signal light, but the positioning of the optical receptacle becomes difficult due to obstruction of the light-emitting surface detection
Solution Approach 1:
The optical receptacle is divided into a first optical device and a second optical device. The first optical device contains the light separation part with divided reflection surface for separating monitor light and signal light, while the second optical device contains the light-emitting surface detection unit. This segmentation allows the light separation function and positioning function to operate independently without mutual interference, resolving the contradiction between light separation reliability and positioning accuracy.
2Manufacturing precision
If active positioning is used to achieve accurate positioning of the optical receptacle, then the coupling efficiency can be maintained, but the time and manpower required for manufacturing increase
Solution Approach 1:
The second optical device includes a light-emitting surface detection unit that enables the optical receptacle to perform self-positioning during assembly. The detection unit detects the light-emitting surface of the light source component through the first optical device, allowing the position to be determined automatically without requiring complex active positioning systems. This self-service positioning mechanism maintains manufacturing precision while significantly reducing the time and manpower required, thereby improving productivity.
