Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar energy collection systems are costly, labor-intensive, structurally inferior, and mechanically complicated, requiring meticulous on-site assembly in harsh conditions without precise control, and struggle to accurately space photovoltaic panels for optimal performance across varying temperatures.
Innovation Solution
A bi-directional support system with tubular support rails and gravity clips allows for off-site assembly to precise specifications, enabling easy attachment and spacing of solar panels, with bolts and nuts forming a foldable structure for efficient shipping and secure on-site installation, using T-slot and C-slot channels for adjustable attachment and wire retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard metal framing channels and clips are used to support solar panels, then the panels can be secured in place, but the system becomes costly, labor-intensive, and mechanically complicated
Solution Approach 1:
The support system is divided into discrete modular components: adjustable support feet, telescoping rails with T-slot channels, and panel clips. These segments can be independently assembled and configured to match specific installation requirements, reducing overall system complexity while maintaining reliability.
Solution Approach 2:
The telescoping rails with T-slot channels serve multiple functions: they provide structural support, enable adjustable panel spacing, allow for electrical wiring integration, and facilitate easy assembly/disassembly. This multi-functionality eliminates the need for separate components, reducing system complexity.
2Manufacturing precision
If meticulous on-site assembly is performed to achieve precise panel spacing, then optimal performance is achieved, but installation becomes labor-intensive and costly
Solution Approach 1:
The support feet and telescoping rails are pre-assembled into modular units with built-in adjustment mechanisms before delivery to the site. This preliminary preparation allows installers to quickly configure precise panel spacing without time-consuming on-site fabrication or measurement, thereby maintaining precision while improving installation speed.
Solution Approach 2:
The telescoping rails incorporate T-slot channels that allow for dynamic adjustment of panel positions along the rail length. This dynamic capability enables installers to achieve precise spacing configurations quickly by simply sliding components into position rather than performing meticulous measurements and drilling during installation.
3Ease of manufacture
If fixed spacing is used for solar panels, then assembly is simplified, but the system cannot accommodate thermal expansion and contraction across varying temperatures
Solution Approach 1:
The telescoping rails with T-slot channels provide dynamic adjustment capability that allows the panel spacing to be modified in response to thermal expansion and contraction. The rails can be extended or repositioned to maintain optimal spacing as temperature conditions change, thereby providing both assembly simplicity and temperature adaptability.
Solution Approach 2:
The support system incorporates adjustable parameters including rail length, panel spacing, and clip positioning. These parameters can be changed to accommodate thermal effects, allowing the system to maintain performance across varying temperatures while preserving assembly simplicity through the modular design.
4Adaptability or versatility
If multiple separate components are used for support and wiring, then functionality is enhanced, but the system becomes heavier and more complicated
Solution Approach 1:
The T-slot channels in the telescoping rails are designed to simultaneously accommodate both structural support functions and electrical wiring integration. Wiring can be routed through or alongside the same rail structures that provide mechanical support, merging multiple functions into a single integrated component and reducing overall system weight.
Solution Approach 2:
The telescoping rails serve dual purposes: providing structural support for the panels and serving as conduits for electrical wiring. This multi-functionality eliminates the need for separate wiring channels or additional structural elements, thereby reducing system weight while maintaining enhanced functionality.

AI summary
An array of photovoltaic panels is supported in rows and columns spaced from one another using a foldable bi-directional span of support members. The support members include a plurality of support joists and support rails braced at an incline. Each support rail is tubular and generally rectangular, having a lower wall section with a T-slot channel for acceptance of the head of a bolt for adjustable attachment with the support joist. Also, the support rail may have a C-slot channel for retaining electrical wires. Clips are used to secure each panel to upper wall portions of underlying support rails. Each clip has a generally U-shaped gasket and is retained to a corresponding support rail through a threaded hole in a top wall of the support rail that receives a bolt or similar threaded fastener.
