Star-Shaped Cable Management Device for Aircraft Bundles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable management devices for aircraft cause damage to sensitive coaxial cables due to external pressure during installation, requiring complete route replacement and being complex to install, especially for electrical cables.
Innovation Solution
A star-shaped cable management device with outer-radial recesses and a retaining clamp that allows cable insertion without squashing, using a radially-slit ring clamp with anti-rotation and anti-slide features, eliminating the need for self-vulcanising tape and simplifying installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a plastic clamp with self-vulcanising tape is used to secure cable bundles, then the cables are protected from mechanical damage, but coaxial cables suffer from external pressure that negatively affects signal transit times
Solution Approach 1:
The clamp is divided into two distinct parts: a star-shaped cable management element that provides gentle support for individual cables through outer-radial recesses, and a separate retaining clamp that secures the bundle without direct contact with cables. This segmentation allows mechanical strength to be provided by the retaining clamp while cable protection is provided by the star-shaped element, eliminating harmful pressure on coaxial cables.
Solution Approach 2:
The star-shaped cable management element acts as an intermediary between the retaining clamp and the cables. It provides a protective interface that distributes forces evenly and prevents the retaining clamp from exerting direct external pressure on the cables, particularly protecting sensitive coaxial cables while still allowing secure bundling.
2Object-affected harmful factors
If a star-shaped cable management element with intermediate ring is used, then gentle bundling of individual cables is achieved, but the installation process becomes elaborate and complex
Solution Approach 1:
The invention merges the cable management function and the retention function into a single integrated device. The star-shaped cable management element and the retaining clamp are combined so that the retaining clamp directly secures the star-shaped element without requiring separate intermediate rings on each cable. This integration simplifies the installation process while maintaining gentle cable bundling.
Solution Approach 2:
The retaining clamp serves multiple functions: it secures the star-shaped cable management element to the support structure, maintains the bundled configuration of cables, and provides attachment to stationary supporting structures. This multi-functionality eliminates the need for separate intermediate rings and simplifies the overall installation process.
3Stability of the object's composition
If separate retaining brackets with stable line are used for attachment, then stable mounting to supporting structure is achieved, but the installation process becomes elaborate and time-consuming
Solution Approach 1:
The retaining clamp integrates the attachment function directly into the cable management device. The attachment portion of the retaining clamp provides direct mounting to stationary supporting structures without requiring separate retaining brackets or stable lines. This integration maintains mounting stability while significantly reducing installation time and complexity.

AI summary
A cable management device accommodates bundles of cables in an aircraft. The cable management device includes a star shaped cable management element and a retaining clamp. The star-shaped cable management element includes a plurality of outer-radial recesses disposed in an outer radius of the star-shaped cable management element that are spaced apart from each other. Each outer-radial recess is configured to accommodate a cable inserted therein. The retaining clamp is disposed around an outer circumference of the star-shaped cable management element so as to encompass the star-shaped cable management element and close the outer radial recesses. The retaining clamp includes an attachment portion configured to affix the cable management element to a stationary supporting structure.
