Pivotable Plastic Optical Module for Component Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical telecommunication modules with pivoting designs are impractical for high-capacity and large-height configurations, as they lack easy access and robustness for component installation and maintenance.
Innovation Solution
An optical telecommunication module with a plastic housing featuring a pivotable rear plate and cover plate, allowing 90-degree and 180-degree movement respectively, and a metal front adapter plate for secure storage and connector management, along with a mounting frame and lateral support for flexible pivot axis orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cover plate is made pivotable relative to the front plate and connected to the back plate by a clip arrangement, then the module structure is simplified and easier to assemble, but the module becomes impractical for high-capacity and large-height configurations where easy access to components is required
Solution Approach 1:
The housing is divided into multiple independently pivotable plates (cover plate, rear plate, front plate) that can be accessed separately. This segmentation allows the cover plate to pivot 180 degrees for easy component access while the rear plate pivots 90 degrees for cable management, resolving the contradiction between simplified assembly and ease of operation by providing targeted access to different components without requiring full disassembly.
2Adaptability or versatility
If the module is designed for small capacity with low height, then the simplified cover plate configuration is suitable, but it cannot accommodate high-capacity applications requiring great height equal to several standardized units
Solution Approach 1:
The housing transitions from a static structure to a dynamic one with multiple pivotable plates. The cover plate can pivot 180 degrees and the rear plate 90 degrees, providing adaptive access configurations. This dynamic structure allows the same module design to serve both small-capacity applications (where plates remain closed) and high-capacity applications (where plates can be opened for component intervention), resolving the adaptability contradiction.
3Adaptability or versatility
If multiple pivoting arrangements are integrated into the module, then flexibility in installation and storage is improved, but the device complexity increases
Solution Approach 1:
The pivoting mechanism is segmented into independent hinge joints for each plate (cover plate hinge, rear plate hinge) rather than a complex integrated mechanism. Each hinge is a simple rotational joint allowing independent movement of its associated plate. This segmentation reduces overall device complexity while maintaining installation flexibility, as each plate can be operated independently without affecting the pivoting capability of others.
4Adaptability or versatility
If the rear plate is made pivotable relative to the bottom plate with guiding and splicing parts integrated, then functionality is improved, but the manufacturing complexity of the plate structure increases
Solution Approach 1:
The guiding parts, splicing parts, and cable management features are merged into the rear plate as integrated molded features rather than separate components. The rear plate is manufactured as a single piece with built-in channels for cable guidance, splicing areas, and mounting features. This merging reduces the number of separate parts to manufacture while providing comprehensive functionality, resolving the contradiction between functional capability and manufacturing complexity.
