Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of electrical cables can be challenging due to the lack of suitable articles for suspension, particularly in environments like solar farms or electric railways.
Innovation Solution
A hanger system comprising a main part with a holding formation and support portion, optionally with an insertion member, reinforcing member, and closure member, designed to securely attach to elongate articles such as cables, ensuring stability and load support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional hanger systems are used to suspend electrical cables, then installation can be performed, but the hangers may slip or move along the cables, compromising security and reliability
Solution Approach 1:
The hanger system is divided into distinct functional components: a holding formation for securing the cable, a support portion for bearing the load, and optional reinforcing members. This segmentation allows each component to be optimized for its specific function while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The hanger incorporates a detent member that can dynamically engage with the cable to prevent slipping or movement. This dynamic feature ensures the hanger remains securely positioned along the cable while allowing for controlled installation and adjustment, thereby improving reliability without requiring overly complex fixed structures.
2Reliability
If polymeric materials are used for hanger construction, then durability and electrical insulation are improved, but structural strength may be insufficient without reinforcement
Solution Approach 1:
The hanger system combines polymeric materials with metal reinforcing members to create a composite structure. The polymeric material provides durability and electrical insulation properties, while the metal reinforcement embedded within or attached to the polymer structure supplies the necessary structural strength to support cable loads.
Solution Approach 2:
The reinforcing members are strategically positioned in specific locations within the hanger structure where maximum strength is needed, such as at the support portion or attachment points. This localized reinforcement allows the polymeric material to maintain its insulating properties in areas where electrical protection is critical while providing structural strength only where mechanically required.
3Reliability
If a secure attachment mechanism is implemented to prevent hanger movement, then reliability improves, but the device complexity increases
Solution Approach 1:
The detent member provides a dynamic securing mechanism that passively engages with the cable to prevent hanger movement along the cable. This simple yet effective mechanism relies on the interaction between the detent geometry and the cable surface, achieving reliable movement prevention without requiring complex active control systems or multiple components.
