Foldable Solar Panel Stand Assembly to Reduce Material and Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar panel stand arrangements are costly, material-intensive, and complex to assemble, with high wind loads and transportation challenges due to large, one-piece designs and the need for separate fasteners.
Innovation Solution
A stand arrangement using two separate, foldable stands with a minimal wind surface area, assembled without tools, and connected to a module frame using a rail with U-profiles and snap-in cups, providing stability and anti-twist protection, and optionally incorporating stiffening elements for increased rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a one-piece stand design is used, then structural stability is achieved, but material usage increases and wind load surface area expands
Solution Approach 1:
The stand is divided into multiple separate components (first stand, second stand, rail) that can be assembled together. This segmentation reduces material usage while maintaining structural stability through the interconnected framework, directly resolving the contradiction between stability and material consumption.
2Stability of the object's composition
If a one-piece stand design is used, then structural stability is achieved, but wind load surface area increases
Solution Approach 1:
By segmenting the stand into separate components with gaps between them, the continuous surface area exposed to wind is broken into smaller sections. This reduces the overall wind load while maintaining stability through the framework structure.
3Reliability
If separate fastening means are used, then panel securing is achieved, but production and assembly complexity increases
Solution Approach 1:
The fastening function is merged into the stand structure itself through integrated fastening elements (such as clips or attachment points built into the stand components). This eliminates the need for separate fastening means, reducing assembly complexity while maintaining reliable panel securing.
4Strength
If tubular profile mounting rails are used, then structural support is provided, but cost and weight increase
Solution Approach 1:
The mounting rail cross-section is changed from a tubular profile to a different geometric configuration (such as an open profile or flat section). This parameter change reduces material consumption and cost while maintaining adequate structural support through optimized geometry and distribution of structural elements.
