Fiber Optic Adapter Shared Lightproof Plate Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic adapters require additional components and complex assembly processes to mount lightproof plates, which increase costs and reduce assembly efficiency due to the need for individual lightproof plates for each port and additional metal frames for fixation.
Innovation Solution
A fiber optic adapter design where two adjacent ports share a single lightproof plate with a rotation shaft, allowing the plate to open and close, and an elastic needle mechanism to ensure secure closure, eliminating the need for separate lightproof plates and metal frames, and simplifying assembly by using a cover that engages with the adapter body without additional fixed structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a lightproof plate is mounted on each port with an external clamping portion, then dust and light are blocked, but the external clamping portion protrudes into the port and reduces internal space
Solution Approach 1:
Two adjacent lightproof plates are merged into a single integrated structure that serves both ports simultaneously. The shared lightproof plate is mounted on the partition wall between ports, eliminating the need for separate external clamping portions for each port while maintaining dust and light blocking functionality.
2Reliability
If a cover and metal frame are used to fix the lightproof plate, then the lightproof plate is securely mounted, but the number of components increases and assembly complexity increases
Solution Approach 1:
The metal frame component is extracted and eliminated from the structure. Instead of using a separate metal frame to fix the lightproof plate, the lightproof plate is directly mounted on the partition wall of the adapter body, with the cover serving both protective and fixation functions.
Solution Approach 2:
The cover is given multiple functions: it protects the internal components and simultaneously serves as a fixation structure for the lightproof plate. The partition wall also serves dual purposes as a structural support and as the mounting surface for the shared lightproof plate.
3Object-affected harmful factors
If separate lightproof plates are used for each port, then each port is individually protected, but the number of components increases and assembly efficiency decreases
Solution Approach 1:
Two separate lightproof plates are merged into a single shared lightproof plate structure that protects both ports simultaneously. This integrated design reduces the number of components from two separate plates to one, and consequently reduces assembly operations while maintaining individual port protection.
Applied Scientific Principles

Function Achieved in This Case
This design reduces the number of components, simplifies assembly, and decreases costs while maintaining effective dust and lightproofing, improving assembly efficiency and structural strength without affecting internal port space.
Implementation Method 1
A first end of the lightproof plate is provided with a rotation shaft. The respective two adjacent ports are paired ports. Each of opposite inner walls of the paired ports are provided with a rotation slot adapted to the rotation shaft, the lightproof plate rotates around the rotation shaft to open or close the paired ports
