Optical Module Pull Ring Assembly for No-Rework Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical module designs face inefficiencies in production due to the need for re-debugging and re-testing when replacing the unlocking pull ring, as the upper lid must be opened, disrupting previously completed debugging and testing processes.
Innovation Solution
The optical module incorporates a housing with suspension arm accommodating grooves and travel limiting grooves, allowing the pull ring assembly to move left-right along a specific path without separating from the housing, enabling easy replacement without disassembling the optical assembly or circuit board assembly, thus eliminating the need for re-debugging and re-testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pull ring assembly is disposed between the upper lid and base, then the unlocking function is achieved, but the upper lid must be opened for replacement causing re-debugging and re-testing
Solution Approach 1:
The pull ring assembly is segmented from the upper lid structure and repositioned to the bottom wall of the housing. This segmentation allows the pull ring assembly to be independently accessible and replaceable without affecting the upper lid or requiring disassembly of the housing, thereby enabling replacement without re-debugging and re-testing and improving production efficiency
Solution Approach 2:
The pull ring assembly is relocated from the vertical dimension (between upper lid and base) to the horizontal dimension (on the bottom wall external surface). This dimensional change provides external accessibility to the pull ring assembly, allowing replacement from the bottom side without opening the upper lid, thus avoiding repetitive debugging and testing procedures
2Ease of repair
If the upper lid is opened to replace the pull ring, then the pull ring can be accessed, but previous debugging and testing must be repeated
Solution Approach 1:
The pull ring assembly is extracted from the internal space between the upper lid and base and repositioned to the external surface of the bottom wall. This extraction makes the pull ring assembly externally accessible, allowing replacement without opening the upper lid or disturbing the internal optical and electrical assemblies, thereby eliminating the need for time-consuming re-debugging and re-testing
Solution Approach 2:
The bottom wall serves as an intermediary structure that provides external access to the pull ring assembly without requiring disassembly of the housing or upper lid. By positioning the pull ring assembly on the bottom wall external surface, the design creates an intermediate access path that bypasses the need to open the upper lid, thus preventing loss of debugging and testing results
3Adaptability or versatility
If the pull ring assembly is moved left-right along the line connecting optical and electrical interfaces, then the movement path is constrained, but the assembly integrity is maintained
Solution Approach 1:
The suspension arms are designed with dynamic movement capability within the suspension arm accommodating grooves, allowing the pull ring assembly to move left-right along the line connecting the optical and electrical interfaces. The grooves provide guided movement paths that constrain the motion to a specific trajectory, ensuring the pull ring assembly remains properly positioned while maintaining assembly integrity during replacement operations
Solution Approach 2:
The suspension arm accommodating grooves and travel limiting grooves serve as intermediary structures that mediate between the pull ring assembly movement requirements and the housing structure. These grooves provide constrained movement paths that allow flexibility in pull ring replacement while maintaining the integrity of the overall assembly, balancing adaptability with structural simplicity

AI summary
An optical module includes a housing, a pull ring assembly, an optical assembly, and a circuit board assembly. An optical interface and an electrical interface are formed at two opposite ends of the housing. The housing includes a bottom wall and two side walls. Two suspension arm accommodating grooves are formed on the two side walls. The pull ring assembly includes two suspension arms and a suspension arm connecting portion. Each suspension arm is disposed in a corresponding one of the suspension arm accommodating grooves. The suspension arm connecting portion is disposed on an external surface of the bottom wall of the housing. When the pull ring assembly moves, the suspension arms are subject to limitation by upper groove walls and lower groove walls of the suspension arm accommodating grooves and move left-right along a direction of a line connecting the optical interface and the electrical interface.
