Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable management systems for solar arrays face challenges such as sharp edges damaging current lines, the need for expensive messenger wires and poles, and limited space occupancy, as well as difficulties in adding or removing current lines without damaging them.
Innovation Solution
A cable hanger system featuring a rigid element support coupling that is coupled to the solar panel installation frame, providing a gripping mechanism to securely hold current lines without sharp edges, eliminating the need for messenger wires and optimizing space usage, with a design that includes various shapes like circular, curvilinear, and polygonal configurations to fit different frame types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current lines are secured directly to the solar panel installation frame using cable ties or metal clips, then the current lines are supported and organized, but the sharp edges of the frame can cut or damage the current lines
Solution Approach 1:
The patent introduces a cable hanger as an intermediary component between the solar panel frame and the current lines. The cable hanger includes a support coupling that attaches to the frame and a supported element coupling that holds the current lines, preventing direct contact between the lines and sharp frame edges. This mediator structure eliminates the harmful effect of sharp edges while maintaining effective current line support.
2Object-affected harmful factors
If messenger wires and poles are used to elevate current lines, then the current lines are protected from damage, but the system becomes more expensive and occupies more space
Solution Approach 1:
The patent extracts and eliminates the messenger wire and pole components from the traditional cable management system. By directly coupling the cable hanger to the solar panel frame, the system removes the intermediate messenger wire and pole structures, thereby reducing cost and space occupation while maintaining current line protection through the cable hanger's supported element coupling.
Solution Approach 2:
The patent merges the support function previously distributed across multiple components (poles, messenger wires, cable hangers) into a single integrated cable hanger structure that attaches directly to the solar panel frame. This consolidation eliminates unnecessary components, reduces system complexity and cost, while maintaining effective current line support and protection.
3Ease of operation
If cable ties are used to bundle current lines, then the lines are secured together, but adding or removing current lines requires cutting and reinstalling cable ties, increasing the risk of damage
Solution Approach 1:
The patent implements a dynamic supported element coupling mechanism that allows current lines to be easily added or removed without permanent modification. The coupling structure can accommodate changes in the number of current lines by adjusting the gripping mechanism, eliminating the need to cut and reinstall fixed cable ties, thereby facilitating easy maintenance and modification.
