Single-Piece Cable Hanger for Aerial Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trenching for underground cable installation is hindered by issues like flooding and deep mud, as well as high material and labor costs, which can be mitigated by carrying cables above ground, providing more predictable project costs.
Innovation Solution
A cable hanger system comprising a single piece of material forming a hanger support portion and two cable support portions, allowing for secure retention of cables above ground, eliminating the need for trenching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trenching is performed for underground cable installation, then cable protection is improved, but construction difficulty and cost increase due to flooding and deep mud
Solution Approach 1:
Instead of burying cables underground through trenching, the invention inverts the approach by suspending cables above ground using a cable hanger system. The cable hanger includes a support portion that attaches to a utility pole and cable support portions that hold the cables in an aerial position, eliminating the need to dig through flooded or muddy terrain while still providing secure cable installation
2Reliability
If trenching is performed for underground cable installation, then cable protection is improved, but material and labor costs increase
Solution Approach 1:
The invention inverts the traditional cable installation approach by using aerial suspension instead of underground trenching. The cable hanger system provides adequate cable protection through secure mounting on utility poles while significantly reducing material costs (no need for extensive excavation equipment, backfill materials, or complex trench shielding) and labor costs (simpler installation process without trenching operations)
Solution Approach 2:
The cable hanger is designed as a cost-effective, simple structure that can be easily manufactured and installed. While individual cable hangers may have limited service life compared to permanent underground installations, their low cost and ease of replacement make them economically advantageous, especially in difficult terrain where trenching is prohibitively expensive
3Stability of the object's composition
If multiple cables are installed using traditional methods, then cable organization is improved, but installation complexity increases
Solution Approach 1:
The cable hanger is designed as a multi-functional device that can simultaneously support multiple cables (first cable support portion, second cable support portion, etc.) in an organized manner. Each support portion can hold different cables at different positions, providing stable cable organization while maintaining a relatively simple single-piece structure that reduces installation complexity compared to multiple separate mounting devices

AI summary
A cable hanger includes a first cable support portion, a second cable support portion, and a hanger support portion. The first cable support portion is configured to hold one or more first cables. The second cable support portion is configured to hold one or more second cables. The hanger support portion is configured to retain the first cable support portion and the second cable support portion. The first cable support portion, the second cable support portion, and the hanger support portion are formed from a single piece of material.
