Serpentine Comb Assembly for Cable Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable management methods in enclosures, such as zip ties and bundling, are inefficient in tight spaces and require significant manual effort, especially when cables need to be added, removed, or replaced, due to the stiffness and natural straightness of cables, leading to challenges in organizing and retaining cables effectively.
Innovation Solution
A serpentine comb assembly with curved features that provides axial and lateral retention of cables through friction, eliminating the need for additional securing accessories by bending cables within channels defined by the curved surfaces, allowing for easier installation and access without unbundling entire cable groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional bundling methods (zip ties, Velcro) are used to manage cables, then cables can be grouped and retained, but significant manual labor is required and installation is time-consuming
Solution Approach 1:
The cable management system uses the cable's own stiffness and natural straightness to work in favor of retention. The serpentine channel geometry and curved features automatically guide and retain cables without requiring manual bundling or additional fastening actions, allowing cables to self-organize as they are inserted
Solution Approach 2:
The patent employs curved retention features and serpentine channel paths that utilize the natural tendency of cables to return to their straight state. The curved geometry creates mechanical engagement that passively retains cables through their inherent stiffness, eliminating the need for active fastening mechanisms
2Area of stationary object
If cables are forced through tight spaces and densely packed, then space is utilized efficiently, but cable management becomes more challenging and requires additional bundling devices
Solution Approach 1:
The serpentine channel design utilizes three-dimensional space by creating a winding path that engages cables along their length rather than relying solely on lateral compression. This dimensional approach allows efficient space utilization while maintaining cable accessibility and reducing management complexity
Solution Approach 2:
The cable management system provides different channel geometries and curvature radii tailored to specific cable types and sizes. Each channel is locally optimized for its intended cable, allowing efficient packing while maintaining ease of management through appropriate geometric matching
3Ease of operation
If traditional bundling methods are used, then cables can be retained, but adding or removing individual cables requires undoing the entire bundle
Solution Approach 1:
The cable management system divides the cable group into individual channels, each capable of holding separate cables independently. This segmentation allows any single cable to be inserted or removed from its channel without affecting other cables, eliminating the need to undo entire bundles
Solution Approach 2:
The system provides dynamic cable access where cables can be independently inserted and removed from individual channels as needed. The retention mechanism remains engaged throughout the process, allowing flexible cable management without requiring system-wide reconfiguration
4Device complexity
If curved features are used to retain cables through friction, then additional securing accessories are eliminated, but the channels must be precisely sized for varying cable diameters
Solution Approach 1:
The serpentine channel design with specific curvature radii and geometric features creates a universal retention mechanism that accommodates multiple cable diameters and types within a single structure. The curved geometry provides scalable engagement that works across different cable sizes without requiring multiple specialized components
Solution Approach 2:
The patent utilizes variations in channel curvature radius, width, and depth as design parameters to optimize retention for different cable types. By adjusting these geometric parameters within the serpentine channel design, the system achieves broad compatibility while maintaining a unified structure that eliminates the need for additional accessories
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The serpentine comb assembly enables faster cable installation and easier access by using frictional retention within the channels, reducing manual labor and eliminating the need for traditional bundling methods, while supporting cables of varying diameters without additional restraints.
Implementation Method 1
Each of the channels defines a serpentine path, whereby a cable received in and extending along a length of one of the channels is retained by friction generated between an outer surface of the cable and portions of the facing sides

AI summary
A cable manager or serpentine comb assembly that can be provided as part of or as an add-on accessory to an electronics cabinet or enclosure (such as in a server rack or the like) to provide improved cable management. The cable manager uses a series of spaced-apart curved features or walls (“comb teeth”) to retain cables axially and laterally. The movement restriction provided by the cable manager is a product of the mechanical interaction of a cable, positioned in a channel or void between an adjacent pair of these curved walls/comb teeth, with the curved surfaces on the cable manager. The channels can be sized with varying widths and engagement curvatures to account for flexibility and minimum bend requirements of the cables being retained and managed by the cable manager or based on its intended use.
