Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing column caps for solar arrays are inefficient due to excessive material usage, deformation under load, high fabrication costs, and incompatibility with horizontal beams of non-circular cross sections, making them difficult to install and costly.
Innovation Solution
A solar array column cap design featuring a main body with radial flanges and upper flaps that surround vertical columns, allowing for secure attachment of horizontal beams with U-bolts, and accommodating various beam cross-sections through adjustable angles and materials like steel or stainless steel, reducing material waste and fabrication complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing column caps use traditional casting methods with steel or aluminum material, then structural strength is achieved, but material usage is excessive and fabrication cost increases
Solution Approach 1:
The patent changes the material parameter from traditional steel/aluminum casting to cold-formed steel sections (C-shape, Z-shape, or box sections). This parameter change reduces material usage while maintaining structural strength through optimized section geometry and cold-forming process that enhances material properties.
Solution Approach 2:
The column cap design applies local quality by using different steel section types (C-shape, Z-shape, or box sections) optimized for specific loading conditions and attachment requirements. Each section type provides localized strength where needed while minimizing overall material usage compared to traditional uniform casting.
2Ease of manufacture
If existing column caps are designed for circular cross section beams, then attachment to circular columns is simplified, but compatibility with rectangular or square cross section beams is lost
Solution Approach 1:
The column cap is designed with universal adaptability to accommodate multiple beam cross-section types (circular, rectangular, square) through standardized attachment configurations. The cold-formed steel section design includes flexible flange arrangements that can be configured for different beam geometries, making a single cap design suitable for various solar array support structures.
Solution Approach 2:
The column cap design incorporates dynamic adaptability through adjustable attachment mechanisms that can accommodate different beam cross-sections. The flange configurations can be modified or repositioned to match various beam shapes, allowing the same basic cap structure to serve multiple functions across different solar array designs.
3Reliability
If existing column caps use traditional casting and welding methods, then structural integrity is achieved, but fabrication complexity and installation difficulty increase
Solution Approach 1:
The patent replaces the traditional casting and welding mechanical system with a cold-forming process. This substitution eliminates complex mold fabrication, casting defects, and post-casting welding operations. The cold-formed steel sections are produced through controlled rolling or pressing operations that directly create the final structural shape with inherent integrity, significantly reducing fabrication complexity.
4Ease of manufacture
If existing column caps are designed with fixed geometry, then manufacturing is simplified, but adaptability to different solar array configurations is reduced
Solution Approach 1:
The column cap is segmented into modular components with standardized sections that can be configured for different solar array arrangements. The cold-formed steel section is divided into functional segments (main body, flanges, attachment points) that can be independently optimized or reconfigured, allowing the same basic design to adapt to various array configurations while maintaining manufacturing simplicity through standardized parts.

AI summary
Disclosed herein is a solar array column cap that includes a main body extending between a left side and a right side to define a channel, the channel configured to at least partially receive a vertical column of a solar array support structure such that the main body surrounds the vertical column. The main body further includes a left flange extending radially outwardly from the left side of the channel and right flange extending radially outwardly from the right side of the channel. Further, the main body includes an left upper flap extending from a top edge of the left flange, and a right upper flap extending from a top edge of the right flange, the right upper flap and left upper flap being co-planar. In another embodiment, a body has an opening extending along a center axis from a bottom to a top, the opening configured to receive the vertical column such that the body surrounds the vertical column, and an upper support surface configured to receive a horizontal beam, the upper support surface being located in a plane that is non-perpendicular with the center axis.
