Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching junction boxes to photovoltaic panels are inefficient in providing a secure and flexible mounting solution that allows for easy electrical connections between multiple panels, particularly in commercial installations where multiple modules are interconnected.
Innovation Solution
A bracket system with a central fastener and rotatable/spacer components that attach to both the junction box and the non-photovoltaic side of photovoltaic panels, enabling secure mounting and electrical connection between two or four adjacent panels, with adjustable spacers for versatile positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bracket system with rotatable spacers and central fastener is used to attach junction boxes to photovoltaic panels, then the flexibility and adaptability of mounting positions are improved, but the device complexity increases
Solution Approach 1:
The bracket system incorporates rotatable spacers that can rotate to different positions, allowing the same bracket to adapt to multiple mounting configurations. This dynamic component enables the system to accommodate different panel arrangements and mounting positions without requiring multiple specialized brackets, thus improving adaptability while managing complexity through a single adjustable mechanism.
Solution Approach 2:
The bracket system with rotatable spacers and central fastener serves multiple functions: it attaches junction boxes to panels, adjusts to different mounting positions, and accommodates various panel configurations. This multi-functional design allows a single bracket type to replace what would otherwise require multiple specialized mounting solutions, improving versatility while consolidating components.
2Reliability
If a secure attachment method using brackets and fasteners is used to connect junction boxes to photovoltaic panels, then the reliability of the connection is improved, but the ease of installation is reduced
Solution Approach 1:
The attachment system is divided into separate functional components: the bracket, the rotatable spacers, and the central fastener. This segmentation allows each component to be optimized for its specific function while enabling modular assembly and disassembly. The bracket provides structural support, the spacers provide positioning and rotation capability, and the fastener secures the connection, making the overall installation process more manageable and easier to perform correctly.
3Stability of the object's composition
If a bracket system with multiple components (bracket, fastener, spacers) is used to attach junction boxes, then the stability of the attachment is improved, but the manufacturing complexity increases
Solution Approach 1:
The attachment system is divided into separate functional components: the bracket, the rotatable spacers, and the central fastener. This segmentation allows each component to be optimized for its specific function while enabling modular assembly and disassembly. The bracket provides structural support, the spacers provide positioning and rotation capability, and the fastener secures the connection, making the overall installation process more manageable and easier to perform correctly.

AI summary
A device for attaching a junction box to a photovoltaic. The photovoltaic panel has a photovoltaic side and a non-photovoltaic side. The device includes a bracket with a first side attachable to the junction box and a second side attachable to the non-photovoltaic surface of the photovoltaic panel. A central fastener is attachable at one end to the bracket and a plate is adapted for connecting to the other end of the central fastener and for mounting on the photovoltaic side of the photovoltaic panel. One or more rotatable spacers, connectible to the central fastener, may be located on the non-photovoltaic side of the photovoltaic panel. One or more fixed spacers may be located on the non-photovoltaic side connectible to the bracket.
