Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fiber optic connection boxes are too large for narrow workspaces and have high costs, with limited practical application due to fixed adapter positions requiring sufficient single-fiber cable length for coupling.
Innovation Solution
A compact fiber optic connection assembly featuring a fan-out member with a multi-fiber optical cable and single-fiber optical cables, where the single-fiber optic connectors and adapters are hermetically sealed within outer shields to prevent moisture and water ingress, allowing flexible cable lengths and arrangement for efficient coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional fiber optic connection box is used to house all fiber optic adapters and connectors, then the connection function is achieved, but the device occupies a large volume and cannot be used in narrow workspaces
Solution Approach 1:
The invention divides the connection system into two parts: a compact fan-out module containing only the multi-fiber to single-fiber splitting function, and separate adapter/connector components that can be positioned independently. This segmentation allows the main connection box to be very small while operators can handle adapters and connectors separately during coupling operations, resolving the contradiction between small volume and ease of operation.
Solution Approach 2:
The invention transitions from a three-dimensional box structure to a more linear, extended arrangement where the fan-out module serves as a compact central point and cables extend outward in multiple directions. This dimensional reorganization allows the connection function to be achieved with a much smaller central component while maintaining operational accessibility through the extended cable arrangements.
2Stability of the object's composition
If fiber optic adapters are fixed on the body of the connection box, then the structure is stable, but the single-fiber optical cable must have enough length to reach the adapter, complicating the operation
Solution Approach 1:
The invention makes the adapter mounting position adjustable rather than fixed, allowing the adapter to be repositioned along the cable path as needed. This dynamic positioning capability enables operators to place adapters at optimal locations for cable coupling, reducing the required cable length and simplifying operations while maintaining structural stability through secure but movable mounting mechanisms.
3Adaptability or versatility
If a conventional fiber optic connection box with multiple adapters is used, then the connection function is achieved, but the cost of the device is very high
Solution Approach 1:
The invention uses a universal fan-out module design that can accommodate different numbers and types of fiber connections through standardized interfaces. This multi-functional approach allows the same basic module to serve various connection configurations, reducing the need for multiple specialized components and thereby lowering manufacturing costs while maintaining connection versatility.
Solution Approach 2:
The invention employs standardized, mass-producible adapter and connector components that can be replicated and assembled in various configurations. By using copied, standardized parts rather than custom-designed components for each connection point, the system achieves versatility through modular assembly while significantly reducing manufacturing costs through economies of scale.
