Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cable hanger systems in the solar, mining, and electrical industries face challenges such as hangers easily falling off during installation due to open loop designs, difficulty in maintaining proper orientation, and the need for increased separation of AC and DC cables as per the National Electric Code, leading to complex wire management and increased labor costs.
Innovation Solution
A locking cable hanger system with a captive closed loop spiral attachment that securely grips the messenger wire, maintaining hanger orientation and spacing, and includes separate saddles for cable support, with an optional PVC coating for corrosion resistance and ease of handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If open loop attachment sections are used on cable hangers, then installation is simple, but hangers easily fall off during cable loading process
Solution Approach 1:
The attachment section transitions from a static open loop to a dynamic closed loop that rotates and locks onto the messenger wire during installation, providing both ease of initial attachment and secure locking during cable loading operations
Solution Approach 2:
The closed loop attachment section automatically locks onto the messenger wire through its own rotational movement during installation, eliminating the need for separate locking mechanisms or additional installation steps while ensuring secure attachment
2Productivity
If AC and DC cables are bundled together to simplify wire management, then installation efficiency improves, but signal interference and code compliance deteriorate
Solution Approach 1:
The cable hanger system divides cable bundles into separate AC and DC sections, physically segmenting power-carrying cables from data/control cables while maintaining organized wire management and compliance with NEC separation requirements
Solution Approach 2:
Data and control cables are extracted from mixed cable bundles and separated from AC/DC power cables, eliminating signal interference while maintaining installation efficiency through dedicated cable pathways
3Adaptability or versatility
If multiple cable sizes are accommodated in single hanger system, then versatility improves, but hanger design complexity increases
Solution Approach 1:
The cable hanger system incorporates universal attachment mechanisms and adjustable cable support structures that can accommodate various cable diameters and configurations through a single standardized hanger design
Solution Approach 2:
The hanger system adjusts its functional parameters such as cable support spacing, attachment loop size, and carrier configuration to accommodate different cable sizes while maintaining structural integrity and installation simplicity
