Optical Connector Holder Ribs for Assembly Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical connectors suffer from positional displacement issues during assembly due to the lack of interacting ribs and groove portions, leading to inferior assembly quality.
Innovation Solution
The optical connector incorporates a holder with ribs that extend along the inserting direction, fitted into groove portions in the housing, featuring a temporary engagement portion for initial alignment and a formal engagement portion for secure positioning, preventing pivoting or inclination during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a positioning projection is used to determine the assembling position of the holders relative to the housing, then the assembly position can be determined, but positional displacements occur where the holders are pivoted or inclined to the housing during assembly
Solution Approach 1:
The engagement portion is divided into two distinct segments: a temporary engagement portion for initial positioning and a formal engagement portion for final securement. This segmentation allows the holder to be guided into the correct position temporarily, then firmly locked to prevent any pivoting or inclination, thereby resolving the contradiction between determining assembly position and maintaining positioning stability.
Solution Approach 2:
The temporary engagement portion performs a preliminary action by guiding the holder into the correct assembly position before the final engagement. This preliminary positioning action ensures that the holder is correctly aligned before being firmly secured by the formal engagement portion, preventing positional displacements during the assembly process.
2Ease of manufacture
If the holder is inserted into the housing without additional positioning structures, then the assembly process is simple, but positional displacement occurs where the holder may be pivoted or inclined to the housing
Solution Approach 1:
The positioning and engagement functions are merged into a single integrated engagement portion structure that includes both temporary and formal engagement portions. This merged design provides precise positioning guidance while maintaining a relatively simple assembly process, as the holder is guided and secured in one continuous insertion motion without requiring separate positioning steps.
Solution Approach 2:
The temporary engagement portion acts as an intermediary structure that guides the holder into the correct position during insertion. This intermediary positioning mechanism ensures accurate holder positioning without complicating the overall assembly process, as it provides natural guidance during the insertion motion itself.
