Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robotic optical switching systems face limitations due to entanglement of optical fiber cables, which hinders further switching capabilities and requires careful planning to prevent cable entanglement.
Innovation Solution
An N×N switching apparatus with a tensioned optical fiber system, including a first element maintaining the fiber in tension and a second element for detachable coupling, along with a control unit to manage the fiber's movement and tension, prevents cable entanglement by using a spooling mechanism and adjustable tension to facilitate smooth reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If direct connections are made between optical fiber cables in robotic switching systems, then switching capability is provided, but cable entanglement occurs which prevents further switching
Solution Approach 1:
The patent applies the dynamics principle by making the cable management system movable and adjustable. The cable routing mechanism includes movable guides and tensioning elements that can dynamically reposition cables during switching operations, preventing entanglement while maintaining switching capability. The system transitions from static cable routing to dynamic cable management that adapts to different switching configurations.
Solution Approach 2:
The patent resolves cable entanglement by introducing additional spatial dimensions for cable routing. Instead of planar cable connections, the system uses three-dimensional cable pathways with vertical and lateral separation, allowing cables to be routed above and below switching elements. This dimensional separation prevents cables from tangling while maintaining full switching connectivity.
2Ease of operation
If cable range of movement is limited to prevent entanglement, then entanglement is reduced, but switching reconfiguration capability is restricted
Solution Approach 1:
The patent applies segmentation by dividing the cable routing path into multiple independent segments or zones. Each segment can move or reposition independently within its own spatial envelope, preventing entanglement within each zone while allowing overall system reconfiguration. The switching apparatus is divided into modular sections with dedicated cable management for each, enabling independent optimization of each segment.
3Ease of operation
If careful planning of cable connections is required, then entanglement is reduced, but system complexity and planning time increase
Solution Approach 1:
The patent implements self-service through automated cable management mechanisms that actively prevent entanglement without requiring external planning or intervention. The system includes automated cable routing guides, tensioning devices, and positioning mechanisms that automatically maintain cable order during switching operations. The cable management system serves itself by dynamically adjusting to prevent entanglement as switching occurs, eliminating the need for pre-planning.

AI summary
An N×N switching apparatus for optical components is provided. A switching apparatus includes a first element that provides for a supply of a length of optical fiber in tension and has an interface component for maintaining an end of the optical fiber in tension at a first position. The switching apparatus further includes a second element that has a coupling component for detachably maintaining the end of the optical fiber at a second position. The first and second elements are arranged such that the end of the optical fiber is movable between the first and second elements.
