Pivoting Cable Bundle Hanger for Mobile Solar Panel Abrasion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable bundle hangers for solar panels, especially mobile ones, face issues with shifting positions due to side forces, leading to tension and abrasion problems between the hangers and cables.
Innovation Solution
A cable bundle hanger with a pivot joint that allows the lower section to pivot with respect to the attachment section, reducing tension and abrasion by accommodating the movement of solar panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable bundle hangers are used with mobile solar panels, then the cables can be secured to the panels, but the hangers shift positions due to side forces creating tension and abrasion
Solution Approach 1:
The patent applies the dynamics principle by introducing a pivot joint that allows the lower section of the cable bundle hanger to rotate relative to the attachment section. This dynamic mechanism enables the hanger to adapt its orientation in response to side forces generated by mobile solar panels, preventing position shifts and reducing harmful tension and abrasion on the cables while maintaining secure cable attachment.
2Strength
If stationary mounting options are used for cable bundle hangers, then the hangers can be securely attached, but they cannot accommodate the movement of mobile solar panels
Solution Approach 1:
The pivot joint transforms the static attachment structure into a dynamic one, allowing the hanger to maintain strong attachment to the solar panel frame while adapting its orientation to accommodate mobile panel movement. The pivot mechanism preserves attachment strength through the pivot joint ring and swaged top member connection while enabling rotational movement to follow the panel's tracking motion.
3Strength
If rigid cable bundle hangers are used, then the structure is simple and strong, but they create side forces that move or disengage the hangers over time
Solution Approach 1:
The patent replaces the rigid, fixed-orientation hanger structure with a dynamic pivot joint system. The pivot joint maintains the structural strength needed to support cable loads while allowing rotational movement that prevents the buildup of side forces. This dynamic adaptation eliminates the position instability and disengagement issues that occur with rigid hangers on mobile panels.

AI summary
A cable bundle hanger secures cables routed to solar panels. The cable bundle hanger includes an attachment section and a lower section. The attachment section engages a solar panel frame to secure the cable bundle hanger. The attachment section includes an attachment member and a pivot joint ring. The lower section is pivotally secured to the attachment section. The lower section has a swaged top member. The swaged top member pivots within the pivot joint ring thereby enabling the lower section to pivot with respect to the attachment section.
