Universal Cable Hanger With Adjustable Gripping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hanger systems for securing communication cables are inefficient due to the need for multiple hangers to accommodate various cable sizes and structural attachments, leading to increased storage, transportation, and maintenance challenges, and known stackable hangers exacerbate wind profile and structural stress.
Innovation Solution
A universal cable hanger with a fixed block and movable block design that adjusts to different cable sizes, featuring curved sections, thumb grips, and adjustable attachment methods, allowing for secure mounting on various structures and stacking without structural compromise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple hangers of different sizes are used to accommodate various cable sizes, then cable size compatibility is improved, but device complexity and storage requirements increase
Solution Approach 1:
The hanger is designed with a universal structure that can accommodate multiple cable sizes through a single device type. The fixed block with curved sections and the movable block with adjustable arms create a standardized interface that adapts to different cable diameters, eliminating the need for multiple specialized hanger sizes.
Solution Approach 2:
The movable block with its movable arms allows dynamic adjustment of the gripping width to match different cable sizes. The arms can be positioned at various intervals along the curved path, enabling the same hanger to securely hold cables of varying diameters through mechanical adjustment rather than requiring multiple fixed-size hangers.
2Adaptability or versatility
If multiple hangers for various cable sizes are stored and carried, then cable size compatibility is improved, but ease of operation and installation efficiency deteriorate
Solution Approach 1:
Technicians only need to carry and store one type of universal hanger instead of multiple size-specific hangers. The standardized design with curved sections and adjustable arms allows a single hanger type to serve all cable size requirements, simplifying inventory management and field operations.
Solution Approach 2:
The hanger is pre-configured with curved sections and arm positions that can be quickly adjusted in the field. The design allows technicians to rapidly adapt the hanger to different cable sizes without requiring complex tools or procedures, maintaining installation efficiency while improving versatility.
3Quantity of substance
If stackable hangers are used to support increasing number of cables, then cable capacity is improved, but wind profile and structural stress increase
Solution Approach 1:
Multiple hangers are stacked in a nested configuration where each hanger is positioned within the structural envelope of the others. This nesting arrangement allows multiple cables to be supported vertically while minimizing the overall horizontal profile, thereby reducing wind load and structural stress compared to lateral spreading configurations.
Solution Approach 2:
Instead of spreading multiple cable supports horizontally which increases wind profile, the hangers are stacked vertically in the vertical dimension. This dimensional transition allows increased cable capacity while maintaining a compact horizontal footprint, reducing the harmful wind profile effect.

AI summary
A universal cable hanger or clamp that can accommodate a variety of cable sizes, and can be mounted on a variety of structures in a various ways. The hanger includes a fixed block with a movable block, where the fixed block can be clamped or attached to a fixed structure, and includes a pair of partially open curved sections adapted to receive and hold cables of various sizes. The movable block includes two curved or V-shaped or U-shaped arms that correspond to the partially open curved sections. As the movable block is inserted into the fixed block, the arms close off the curved space, in whole or in part, to grip and hold a cable in the space. Two posts on the movable block engage indentations in slots on the fixed block, thereby providing a curved space of fixed size corresponding to different cable sizes. Multiple hangers can be stacked.
