Reconfigurable Cable Duct System with Movable Flaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable duct systems in electrical equipment enclosures are typically configured based on a specified cable feed direction, making them unusable if the direction needs to be changed at the installation site from top to bottom or vice versa.
Innovation Solution
The enclosure design includes two side-by-side cable ducts with a movable flap that can be reconfigured to allow cable routing from either the top or bottom, enabling flexible cable feed direction changes by blocking or allowing access through shared openings between the ducts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cable ducts are configured based on a specified cable feed direction prior to delivery, then the cable duct system provides a fixed and simple structure, but the system becomes unusable if the cable feed direction needs to change at the installation site
Solution Approach 1:
The cable duct system incorporates movable flaps that can be repositioned between different positions to dynamically change the cable routing path. The flaps can be moved to block certain openings and direct cables through alternative paths, allowing the system to adapt from a top-feed configuration to a bottom-feed configuration or vice versa, transforming a static structure into a dynamic, reconfigurable system.
Solution Approach 2:
The cable duct system is divided into multiple segments with separate controllable flaps in different ducts. Each flap can be independently positioned to control cable flow through specific openings. This segmentation allows selective activation of different cable paths without requiring complete system redesign, enabling flexible reconfiguration while maintaining overall system integrity.
2Adaptability or versatility
If cable ducts are configured for a specific cable feed direction, then the manufacturing and installation process is simplified, but the system lacks flexibility when installation site requirements change
Solution Approach 1:
The cable duct system is designed with multiple openings and movable flaps that enable the same duct structure to serve multiple functions - accommodating both top-feed and bottom-feed cable configurations. The flaps can be positioned to create different effective duct paths, allowing a single manufactured unit to adapt to various installation site requirements without requiring custom manufacturing for each configuration.
3Adaptability or versatility
If the cable feed direction changes from top to bottom or vice versa at the installation site, then the system becomes unusable with traditionally configured cable ducts, but adding reconfigurability increases structural complexity
Solution Approach 1:
The system merges multiple cable routing paths into a single integrated duct structure with shared openings and common cable access points. By combining top-feed and bottom-feed paths within the same physical duct system and using flaps to control flow between them, the design achieves reconfigurability without requiring completely separate duct systems for each configuration, thus limiting the increase in structural complexity.
