Optical Waveguide Connector Lid Ratio for Automatic Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical waveguide connectors face challenges in automatic assembly due to misalignment issues between the lid and the main body, leading to reduced optical connecting accuracy and adhesive fixation problems.
Innovation Solution
The optical waveguide member connector kit features a design where the lid is positioned between the first and second walls with a specific length ratio, forming gaps that increase in cross-sectional area towards the bottom wall, allowing for reliable adhesive filling and improved fitting properties, ensuring accurate optical connection and fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the width of the PMT lid portion is set slightly smaller than that of the opening portion (99.3%±0.1%), then the fitting can be achieved by manual operation, but the lid cannot be fitted by automatic operation due to contact between the lid end and main body inner end
Solution Approach 1:
The patent changes the width ratio parameter from the conventional 99.3%±0.1% to a larger value within 95%-99%, and simultaneously introduces a tapered section with specific inclination angle (5-45 degrees) to modify the geometric parameters of the fitting interface, enabling both manual and automatic operations
2Extent of automation
If the width of the PMT lid portion is set greatly smaller than that of the opening portion, then the lid can be fitted by automatic operation, but the optical waveguide end floats upward reducing optical connecting accuracy
Solution Approach 1:
The patent optimizes the width ratio parameter to be within 95%-99% (not greatly smaller), and introduces a tapered section with inclination angle of 5-45 degrees to provide sufficient support to the optical waveguide end, preventing floating while enabling automatic operation
Solution Approach 2:
The patent adds a tapered dimension along the length direction of the lid, creating a gradual transition from the wider opening portion to the narrower fitting portion, which provides both automatic fitting capability and optical waveguide support
3Device complexity
If the width of the opening portion is the same as that of the PMT lid portion, then the dimensions are simplified, but the lid cannot be fitted due to contact between the lid end and main body inner end
Solution Approach 1:
The patent segments the lid structure into three distinct sections: a wider opening portion, a tapered intermediate section, and a narrower fitting portion, allowing each section to serve its specific function while maintaining overall dimensional control

AI summary
An optical waveguide member connector kit includes an optical waveguide member including an optical waveguide and a connector accommodating the optical waveguide member. The connector includes a main body having a bottom wall, and a first wall and a second wall that extend from the bottom wall toward one side in a thickness direction of the bottom wall and face each other at spaced intervals therebetween, and a lid disposed between the first wall and the second wall and sandwiching the optical waveguide member with the bottom wall when the optical waveguide member is accommodated in the connector. A ratio (L1/L2) of a length L1 in a facing direction of the lid to a facing length L2 between the first wall and the second wall is 0.80 or more and 0.99 or less.
