Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching junction boxes to photovoltaic panels are inefficient and lack a standardized solution for secure and flexible mounting, particularly for multiple panels, which affects electrical connectivity and installation ease.
Innovation Solution
A bracket system with a central fastener and rotatable/spacer components that allows attachment to both photovoltaic and non-photovoltaic sides of panels, enabling secure mounting and electrical connection of two or four adjacent panels within a junction box, with adjustable spacers for versatile positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods for attaching junction boxes to photovoltaic panels are used, then installation can be completed, but the attachment is inefficient and lacks standardized secure mounting for multiple panels
Solution Approach 1:
The patent combines multiple attachment functions into a single integrated bracket system. The bracket simultaneously attaches to multiple photovoltaic panels and the junction box, creating a unified mounting structure that secures all components together in one operation, thereby improving both reliability and installation efficiency.
Solution Approach 2:
The bracket is designed with universal applicability to attach to multiple panels (two or four adjacent panels) and the junction box simultaneously. The standardized bracket design can be used across different panel configurations, providing a multi-functional attachment solution that works for various installation scenarios.
2Adaptability or versatility
If a standardized bracket system with central fastener and spacers is used, then secure and flexible mounting is achieved, but device complexity increases
Solution Approach 1:
The bracket system is divided into distinct functional components: the main bracket body, central fastener, and adjustable spacers. Each component has a specific function, and they can be independently adjusted or replaced. This segmentation provides mounting flexibility while keeping each individual component relatively simple in design.
Solution Approach 2:
The bracket system incorporates dynamic elements including the rotatable plate and adjustable spacers that can be moved to different positions. This dynamic capability allows the same bracket structure to adapt to different panel configurations and spacing requirements, providing versatility without requiring multiple different bracket designs.

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.
