Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical module manufacturing techniques face challenges with complex fiber coiling operations, long processing times, and difficulty in ensuring the bending radius of optical fibers, which affects the power stability of the optical module.
Innovation Solution
The optical module incorporates a fiber coiling member with a fiber coiling body and stop walls to stabilize the optical fiber, allowing it to coil and extend along the fiber coiling wall while being limited by the stop space, ensuring consistent bending radius and power stability without the need for deliberate correction during coiling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the optical fiber is arranged by coiling to avoid breakage due to stress, then the reliability is improved, but the device complexity and processing time increase
Solution Approach 1:
The fiber coiling member is pre-formed with a specific coiling structure before the optical fiber is installed. The accommodating cavity and guide walls are pre-configured to guide the fiber into the correct coiled position, eliminating the need for complex manual coiling operations during assembly.
Solution Approach 2:
The fiber coiling member acts as an intermediary component between the optical fiber and the housing. It provides a structured medium that receives and secures the coiled fiber, simplifying the overall assembly process while maintaining the fiber's protected coiled configuration.
2Reliability
If the optical fiber is coiled to ensure proper bending radius, then the reliability is improved, but the processing time increases
Solution Approach 1:
The fiber coiling member is pre-formed with the correct coiling geometry and dimensions. The accommodating cavity and guide walls are pre-configured to maintain the proper bending radius, eliminating the need for time-consuming manual coiling and adjustment operations during assembly.
Solution Approach 2:
The fiber coiling member is designed to automatically guide and secure the optical fiber into the correct coiled position through its structural features. The guide walls and accommodating cavity work together to self-align and hold the fiber, eliminating the need for operator intervention and adjustment.
3Ease of manufacture
If the optical fiber is directly connected to minimize length, then the ease of manufacture is improved, but the reliability deteriorates due to stress breakage
Solution Approach 1:
The fiber coiling member is pre-formed with a specific coiling structure before the optical fiber is installed. The accommodating cavity and guide walls are pre-configured to guide the fiber into the correct coiled position, eliminating the need for complex manual coiling operations during assembly.

AI summary
An optical module, comprising a circuit board (110), a photoelectric assembly (130) electrically connected to the circuit board (110), an optical interface (120), and optical fiber (140) in optical communication with the photoelectric assembly (130) and the optical interface (120), and a fiber coiling member (150). The fiber coiling member (150) comprises a fiber coiling body (151) enclosing an accommodating cavity (1510), and the fiber coiling body (151) is provided with a bottom wall (1512) and a fiber coiling wall (1511) extending from the bottom wall (1512) in the thickness direction of the circuit board (110). The fiber coiling wall (1511) defines a peripheral boundary of the accommodating cavity (1510). The fiber coiling member (150) further comprises stop walls (152) arranged opposite to the bottom wall (1512) in the thickness direction of the circuit board (110), and protruding from the fiber coiling wall (1511) to the interior of the accommodating cavity (1510). The accommodating cavity (1510) is provided with a stop space formed between the stop walls (152) and the bottom wall (1512), and the optical fiber (140) coils and extends along the fiber coiling wall (1511) and is limited in the stop space by the strop walls (152). The fiber coiling efficiency of the fiber coiling member (150) is high, and the bending radius of the optical fiber remains unchanged at will.
